I hope most people realize the effort that goes into shooting and editing these videos, adding all the graphics and animations, switching to macro lenses, dragging the camera around mounting and focusing, explaining technical jargon while being funny. I certainly enjoy and appreciate them. It's also the first tool grinding video that didn't make me pass out from boredom
Andrew Cullen I'm a master welder took video production for 4 years in school and this stuff is rocket science literally down to the nutty gritty using 1000ths this and rocket 🚀 science. that's about it. I've used manual machines like presses brakes drills saws and even a mill cutter and I've known how to stick weld for almost ten years(yes I still do it because my vlog playing online video games haven't hit big for me yet. give me the money💰 ) my step dad had own business but I left after I got basics because family and business doesn't mix. believe it. but this shit rocket 🚀 science even after all that and every video online until I can put it to work(he has fab not machine shop and I don't have time to play with these machines they pay the bills),
Andrew Cullen I'm serious adobe movie maker like from when it was created through the 7th versos I believe. and honestly I've been working steel and stick welding ten years mug welding he wouldn't let me do for the first year until I could pass bend test and work in the field a year and tig about the same. and I'm telling you you're wrong on every level. 🚀 rocket science
Tool maker 65 years and your descriptions are great. It's one thing to know how, but quite another thing to explain it. I've done everything there is to do in the industry, but still enjoy and learn from your explanations. Thank you and God bless you.
This is the 4th time I've watched this video. That's what This Old Tony has going on that very few other machinist RUclipsrs manage to pull off: These videos are fantastically rewatchable.
I'm going to have my apprentice watch this video, it's absolutely the best primer on single point tooling I've ever run across. I started learning the trade from old machinists 40 years ago and I'm still doing it and still learning! Thanks Tony for helping me train my youngers!
I often think how awesome it must be starting on an engineering apprenticeship nowadays. There is so much amazing information to be had from the RUclips channels, In fact I started as an apprentice in 1967, and I am _still_ learning new stuff. (Not from this video however. We did not have tipped tools when I started, so I have ground a LOT of HSS tool bits. I actually ground one two days ago because I wanted to cut hardwood on the metal lathe, and tipped tools are not great on wood. You can buy the blanks cheap as chips from wish.com
@@TrevorDennis100 You could try to grind the shape of a skew chisel into a solid HSS bar. Just watch a few videos on how skew chisels are used in woodturning and you'll know how to grind the mini version in your stock so that its positioned to the wood like a skew chisel to the wood in woodturning.
Applied Science stole my line. I was going to say, "Awesome! This is the best all-in-one video introduction to tool geometry I've ever seen. Nice job!"
I’m 53 years old now living in Ontario Canada and I’ll never forget my grade 9 high school machine shop teacher in the early 80’s. He was originally from Bulgaria and he was frickin amazing! He showed me how to do just this. I have always used his technique on how to make a specific tooling for the lathe. It has served me and saved me throughout the years where I have seen many other tool, makers fall on their face.
@@ThisOldTony The Scooby Doo approach reminded me of Jam Handy films like "Around the Corner" (ruclips.net/video/yYAw79386WI/видео.html) and "Spinning Levers" (ruclips.net/video/JOLtS4VUcvQ/видео.html) and I still think it is the best way to teach a lot of topics. Your videos are more fun than Jam Handy films though, 11/10.
Anyone can learn from their own mistakes, but it slows progression and advancement since it is expending time that could simply be leaped over by knowledge. If one knows what to do and what not to do, the experimental process for advancement can be done instead. No *need* to reinvent the wheel if it isn’t necessary, so to speak.
@@WilliamHelstad Yes, which is why we have referenced resources such as books, manuals, magazines, videos, audio recordings, ect. of knowledge from historical timelines of technology to years of experience from writers. For example, some thrird-world countries bypassed certain technologies because they didn’t have the resources and/or skills other countries had, but as those first-world countries advanced they spread them to the third-world countries. Think of skipping dial-up to DSL, skip b&w T.V./photography to color, land-line phones to cell phones. Manual dexterity is only learned through experience, however with guidance on techniques and form one can acquire mastery much quicker. For instance, if you know how the stir pancake mix you can use that same technique to mix mortar/concrete (knowing more-or-less the consistency). Once the basic fundamental processes, techniques, and principles are learned and understood they can be translated and incorporated into other subjects than the ones which were learned from. I see a lot of basics being missed simply because the necessary skills aren’t translated from other fields which have the same basic principles. Only if they broke it down to to simple steps and processes and used what is already familiar to them would they succeed, and quicker. Sometimes the bigger picture needs to be put aside and ignored.
40 years ago I took the wrong career path being mesmerized by electronics. I didn't recognize I had a talent for working materials back then. I've never had any schooling in metal work but everything I saw in this video made sense. A very well produced video. The hand gestures kept the attention going.
This is absolutely solid gold. My 23 year old son is just now learning to become a machinist oh, and this is the type of irreplaceable priceless information that you just can't get in a class! Thank you so much for your contribution to the art!!! too many young kids are becoming appliance operators with their CNC machines, I was blessed enough to have learned on manual machines when I was much much younger, and it makes the troubleshooting process with a Haas CNC machine much easier.
I just started a college level intro to manual machining class, and both my instructor and my textbook explain the tool geometry pretty well, but you, you TOT, you blew both of them out of the ball park. Excellent Video! I wish he would have played this for my class!
Tony brings the theory to real life using simple down to earth graphical illustration that wake the brain up and provides the viewer an Epiphany Moment in time where the World Stops and the Magic comes to the Light of Day.

Tool geometry on cutting effect has always been more black magic than science for me although having a chance to make my own tool back in school. Thank-you so much for making it super clear! Love your videos
It has finally come to it. The ultimate consequence of watching thisoldtony. It’s still hard believe it. I bought a lathe. And I’m not even (too) embarrassed of saying it was largely because of his videos. This is the third time i’m watching this one. The first, i was but a hobbyist handtool woodworker, who inadvertently fell asleep while watching some other, more woodworking-friendly, of tot’s videos, and woke up midway this one while on autoplay. The second one, I watched because I had seen enough of tony’s videos to understand a little bit better what he is talking about, and was honestly enjoying the technical content and having a better grasp of the jokes. Now, I’m about to grind some hss blanks. Wish me luck. Otherwise, I’ll be sending you an invoice for the price I paid for the lathe. 😆 Thanks for your great work tot! This is how awesome you are! Congrats on 1M subscribers!
I own an ancient Zyto hobby type lathe. Passed down through the family. I followed your instructions and was able to make my own tools in 1/4" HSS in no time. They cut like a dream. Thank you!
This is the most approachable introduction to the subject I've seen. I remember struggling with this for an hour in a machining class I once took, and in the end the instructor had to basically do it for me... I just couldn't understand what I was even trying to do. Now I might try to give another crack at it. Also, funny to boot. Thanks a lot!
Wow! I have no experience with this nor do I have a clue what lathe tools are supposed to look like, but what a wonderful methodology and video for showing someone the HOW and WHY you make the tool as you do. I feel more intelligent just from watching you. Thank you for your Time, effort, experience and wisdom when making this video for us. Beautifully Done!
Probably the single best explanation about a) how to grind HSS tooling, and b) WHY to grind it that way. Absolutely indispensable, and definitely bookmarked for future reference.
I want to let you know, you are incredible. I spent a week attempting to figure out what was going on with rake angles, chip load, etc. during University, and I nearly failed the section. This actually clarified everything so super well. I know that I probably could have put this all together myself, but not nearly as well as this half hour has been. Thank you sooooo much for this.
Again, this video giving insight into the why more than the how suits my needs much better. I keep watching this channel probably until I have seen all 7 years of it. Thanks!
Tony - I agree with folks who praise your skill and talent at setup, videography and narration - you're a natural at this and your production quality absolutely delivers. Beyond that, you are a wonderful teacher and mentor - folks don't realize what a gift this is. I greatly enjoy all of your video productions - thank you for providing these great videos !
Rather than just add my thumbs up, I have to agree with arkwoo, your videos should be a prerequisite for an apprentice machinist, tool and die maker or model maker. I was a machinist and only wished I could have had somebody as good as you instruct me. I had to learn it the hard way and even as I loved what I was doing my instructors were absolutely no help. I was successful, but damn was it hard!
I've been gradually going through watching each of Tony's videos, and every time there's a new one I actually get a bit giddy. These videos are all amazing, it's pretty incredible how much I learn from each one and how entertaining they are at the same time. This guy really doesn't get enough attention in my opinion.
I can not thank you enough for the clearest explanation I have ever seen. This one video cleared all my doubts than in my class I have ever attended. Thank you so much. Thanks for the great efforts to make it easy to understand.
Just ground my first lathe tool based on what you showed here - 3 years after watching it. I honestly am shocked that enough of what you showed stuck in my head that the tool actually worked really well!
Thanks for describing all the reasons for the grinds...it's been over 40 years since Trade Shop Class and I needed the refresher. Picked up an older model Edestaal SL1000 and trying to relearn how to use it correctly. Thanks again...
This is such a great video! This is one of my favorite methods to learn - trial and error, I love that you took the time to make this video and go step by step as though you were solving a problem. I've shared your videos with everyone I know because even if they don't have an interest in machining - they get a real kick out of your presentation which is by far the best of all! Thanks for all of the great content that you produce and I realize this video is a little old... but still :D
Man. you should have been my math teacher in grade school ....you made this complicated subject as clear as it can ever be.. thank you for your time and effort.
That sort of information is the most useful thing in the world, I think reading 100 books is not yet enough to get all that info you mentioned in this video. I love your work!
SIR! You have answered every question about tool bits & the various angles. I do no machine work & never have, but I have insatiable curiosity about many things. Bravo ! & thank you !
Well THANK YOU. After watching hundreds of footage on lathe cutters, I have to state `this was so easy to understand, You did a great explanation through the whole footage, 'and very well filmed, I understood what a relief is on drill bits and after 50 years I now can sharpen my own drill bits through watching other vids, And now ill be able to sharpen cutters etc for a lathe, I take my hat of to you, for your time you've taken out to show us how to do this, So a big thanks' And thank you for not using music which end up drowning over a persons voice.
For a novice like me that's a super-useful video. The fact that you bothered with such high production values and also made it funny is a huge bonus. Very many thanks.
Damn! I've watched this video already... But I have a machining process exam tomorrow and had a hard time understanding this topic. So I rewatched it. You are awesome. Learning from home due to covid, I've never seen a lathe tool in person and your video is definitely the best after searching for so long!
Thank you very much for the info and the effort made to post this. My family ran a motorcycle dealership for 40 years and we bored many cylinders in that time. My dad had been a tool and die maker years before that so we had some knowledge in our shop about cutting tools. Occasionally my dad or I would try to sharpen the cutter for the boring bar (by hand). Because of the years of experimenting with good and bad results, it was really interesting to watch your video. We eventually bought a tool with carbide inserts but we found that we could get much less chatter from our machine if we modified the tip of the insert a little. My theory was the the angle on the end of the tool was just a little different that what we really needed. We had the machine overhauled at one point and that helped some too but having the right tip geometry was key to getting a finish that would hone out easily and make for the best cylinder surface.
Hi Tony what a fantastically presented video. I have just started teaching myself how to use my new mill drill. Purchased my first bit of 1/4" tooling now I feel I can have a good go at sharpening it. Thanks heaps from a new subscriber in New Zealand
OMG The sarcasm and jokes and video edits never disappoint! Thanks so much for doing this. I am not wealthy and bought and am upgrading the dreaded Harbor Fraught Baby lathe. It does 80% of my small stuff I need but it has definately needed every upgrade I've done , A Lot. Now I am starting to do a few things and need to make bits so these vids are a godsend. Thank you.
When doing a boring operation, typically you want the tool to make chips. Long stringy shavings get caught up on your boring bar and ball up inside the work, causing scratched up finishes or breaking your cutting point. Small chips fall into the bottom of the work (tube/pipe or what have you), and just flow out of the work into your chip tray like fluid. With coolant, chips tend to flow out of a bore quite well. I've had some really far from fun boring operations where we couldn't push the tool hard enough to break a chip (due to clamping limitations), and I must say stringy shavings in a bore are a bitch to deal with. If your tool's geometry has a chip breaker built into it, generally as long as the tool is sharp, speeds and feeds will dictate whether or not it breaks a chip. Often times, these speeds and feeds are much harder than you would want to/could even push a hobby machine. Love the videos though, always entertaining.
Got my 50 year old lathe today, Have not even cleaned it up or switched it on yet. Your video makes me think I can do this! Thanks Tony you took away the jargon and added the fun.
ToT is the most informative and entertaining channel on RUclips. The only channel where I still watch every video even if it's on a subject I know I'll never get into. And now that I'm thinking of up grading to a workshop that has more than just a cheap drill press, it's the only channel where I'm re-watching lots of videos =) Thank you ToT =)
While we may not all agree on every aspect of the advice and descriptions offered, a point that the presenter addresses openly in the monologue, this is (IMO) one of the best novice hobby machinist basic instructional videos on the subject of griding high speed tools available RUclips. Nice job .......
Wonderfully informative video. I love the way you describe things. It helps me to understand things at a very basic "first principles" level, which is much more useful than a "here's how to do it" video. Thank you.
This video was really good. Now I undestand perfectly! Nestish-barb-wire is good, buying cutters is cheaper, and feed-rate for metal/alumnium is between 5000~7000. I'm so confident now that I'm going to work alone in my shop all night. Smell ya later
Thanks very much! The way you explained this tool grinding procedure finally allowed me to understand what it is that you are trying to do when grinding the blank. You are an awesome teacher!
I work in a heat treating plant. High speed steels thermal resistance comes from the high molybdenum carbides in the alloy that retain their structure better under heat than regular ferric carbides. It's difficult to work besides a lot of grinding though, it needs to be nearly molten to be movable, and it quenches at nearly the melting point of the steel itself so if you overshoot at all or have a lower alloy than you thought you melt it and potentially burn your molybdenum out. I'm not an expert metallurgist though, I may be wrong and that's just the one variation I've seen.
Hawkeye, this is absolutely the best shop video you ever made! I'm amazed at what repeatability it has! Each time I zero it out I sit back with a cup of Joe to learn and enjoy. If RUclips ever has a VideoLympics in SHS Lathe category this vid would run away with Gold Medals! THANKS!! Wakodahatchee Chris
I'm 76, had 2 seizures and don't take care of myself. All of which definitely affects memory. The plus side of this is movie and home shop video "ReRunAbility". It was only 10 months ago since I posted here but I didn't know that until I started a new comment. Sho nuff, my substance and entertaining rating of this video remains *YOUR ABSOLUTE BEST*!!!! I still love it! 🥰🥰🥰 Wakodahatchee Chris
Thanks so much for the time y. ou spent explaining the various angles and how they affect the cutting process. Now I can approach my tool bit grinding with some real knowledge about how to actually grind them!
Your presentation here is exactly how I started out with tool bits when I knew literally nothing about lathe tool geometry. Went from trying an unground bit too experimenting with different angles.
HSS is the future .... in the home shop! Mastering, or at least getting the basics of grinding HSS tooling will save you so much money and help you get projects done faster. I know that carbide is much more efficient at removing material but you have to look at the big picture. Insert tooling is expensive .. and I'm part Dutch so naturally I avoid the stuff like the plague in the home shop. Stefan grinds his own carbide - something that is probably as economical as using HSS, but you need to master grinding HSS first. Loved the video, as always. Edutainment at its finest!
I've been watching ToT videos since this one was newly released. I've only just had the chance to get my own lathe and finally I can put all of this info to use. Time to grind my first HSS tool. Thanks Tony, you've taught me so much
None of the teachers of my college explained tool geometry this easily. I was struggling understanding all this Angles. Thanks a lot ..... You are a great teacher.... You made this so simple to understand.
Awesome video! Also another example of when you dont want to "break" chips, when i work with a more expensive metal on a lathe ill try and keep my shavings in nice long pieces, especially for silver/brass/high quality steel, as its easy to collect and sort large spring like shavings rather than a bunch of tiny chips, this way you can easily recast your shavings into ingots
Tony, I don't know if you teach for a living but you absolutely should teach. Your knowledge and humor will keep even the most uninterested student engaged and facinated. Kudos. And if only 10% of the people who make videos had your technique, youtube would not be the vast wasteland of shameless self promoters that it has become.
I took a Metal Cutting class back in engineering school, they let us play with lathes, drill presses, and we made our own cutting tool with HS Steel. Your video brings all that back. It was a fun class. Great video BTW, Liked and subscribed.
I really enjoyed the video, but there is one thing that bothers me alot... Why am I watching these kind of videos, when i'm nowhere near a lathe or high speed steel or anything related to this?
It would help your from been screwed by a machinist, when you carried a project to be done. Like going to a Auto Mechanic and he tell you $10. to change a radiator cap because it requires some technical work to do so. Respect.
I was working with some hot rolled steel bar from a big box store that doesn't machine well at all with indexable carbide insert tooling. I re-watched this video, and proceeded to dig out an old 3/8th inch HSS lathe bit I'd fumbled around with grinding a long time ago. I quickly spotted how mine differed from your example and ground it to match yours - minus the chip breaker. Honed the edge and gave it a try. While the mystery metal HRS is still some crappy stuff, the nice sharp HSS cuts instead of plows, and the rounded tip leaves a far and away better finish than my TCMP 21.51 inserts tooling could get on my little benchtop 7x12 mini-lathe. Followed up with a bit of wet-sanding with 400 grit and got about as nice a finish as is possible with this metal with minimal effort. Your intention to help people certainly paid of well for me today. so thank you very much! Your videos are simply outstanding and this particular one has gotten me back into wanting to grind my own tooling again. I think it is time to make up some proper adjustable tool rests for my cheap grinder and do things right this time around. Thanks for the inspiration...!
I don't know how it happened.. I didn't use to have any particular interest in machining past an 'oh that's neat'... But now somehow I'm 12+ hours into watching this channel and now know more in-depth details about this world than I ever thought a human who doesn't do this for a paycheck should know. Very fascinating. If you get sick of doing this stuff, apply for a comedian position. Great comedic timing. I wish I could talk about leatherworking the way you talk about relief angles.
I use to have a family, wife, kids and a little turtle, my life did a 180 turn since I discovered rake angles, curls and chip breaking AND I don't even have an laythe ! I love you dude, keep it up.
Hi mate. I think you kicked a lot of the other grinding videos out of bed here. Although, maybe not the nicest tool to look at, it explained all I liked to know. I particularly liked the pencil analysis. All the little gages kept it all light and digestible, for me at least. Thanks teach.
Tony: I forgot, as always your instructional talks are excellent both in content and the visual display. You convey the "Point" in a very concise and graphic manner.
Newby here, appreciate the humor, good for my sanity quotient, reminds me I bought a metal lathe to have fun with it. Luckily I have ample time to waste, being a retired widower. Many mistakes buying stuff on the internet! A watchmakers lathe with zero accessories and trying to purchase split wire chucks, three tries and no match for the lathe, no name on the lathe that I can read, written in Chinese. I ordered another lathe hoping I can manufacture parts for the watchmakers lathe. I like to tinker! This is an expensive hobby but I am persistent. I have more time and money than good sense. I love your videos!!!
I've been working as a machinist for about 14 years, and I came here to brush up on some basics and found this very refreshing. In a modern workplace with CNC lathes, we rarely grind our own tools. 99% of the time we buy them from other companies that grind them using CNC. Great video! Hand grinding is a very important skill that is becoming lost in the modern world it seems.
Did I hear you right? We're you suggesting Mrs TOT's chocolate chip cookies are harder than aluminum? Another GREAT instructional video. Thank you! Joel.....
That's why TOT sounds so frustrated with chip breaking on aluminum, but also how he built up a wealth of knowledge on tool design. Trying to carve chocolate chips out of Mrs T's cookies is no joke.
As a lathe newbie and an old fart, this video clearly explained the 'black magic' behind the cutter angles. Thank you very much, you have a new subscriber.
I've kust come back to this video after first watching it years ago. I'm in the process of grinding some new tools for my day job and this video is an absolutely superb how-to guide
The chip breaker/controller grind you finally put on that tool completely masked the rake angles you ground into the top of the tool. I know; instructional, exploitative video, but just saying. Thanks for presenting all that and especially starting from a square tool and developing each feature that progressively improved the tool's cutting performance. Very enlightening.
This is the best lathe tool grinding tutorial I've seen yet (and I've seen a bunch). Explaining the actual function of each facet is very helpful. Good job!
At 5:45, I've always called that "chatter." The chatter marks are seen in the corrugated pattern on the OD of the cut area. At 26:59, I wanted to scream "GET BACK!" Positive rake into a grinding wheel? Yikes! I got the same scolding after doing the same thing, then talking about the result. My result was that the tool caught on the wheel and shot toward the concrete floor, leaving a divot. It also took a chunk out of the grinding wheel and ruined the balance. Made quite a noise, followed by some astonished cussing. I was lucky not to be injured, and in retrospect, surprised the wheel didn't come apart. The wheel was shot, but I kept it for a while as a reminder. If I were to attempt the same grinding, I might use a Dremel with a cutoff wheel and clamp the HSS in a vice. Something - ANYthing else. All ranting aside, this is a very informative video, especially regarding chip breakers. I struggle with them, too. If you think 6061 aluminum is bad, consider 304 stainless without a chip break. Lots of sharp razors flying around. Ask me how I know...
Best explanation ever, never had to rewind to try and understand. 100 thumbs up. You focus on the topic and keep the humor to a minimum. Well done I am now a subscriber
Old Tony You skipped the part from 1880 to 1906 when Frederic Taylor invented high speed steel, developed the Feed, Steed, Depth of Cut tables and Flood Coolant necessary to use it to best advantage, then published his findings in his book "On The Art Of Cutting Metals" which is available from Amazon.com otherwise pretty thorough history.
This is an outstanding instructional video. One of the best If seen on the internet. at 14:40 when you faced the tool to the camera as the work see's it. That was brilliant. I wish my instructors would have had a video like this. Thank you for such a great video
Super informative, took a lot of the invisible magic away. What grit/material grinder wheels are more or less ideal for this process? Do you prefer oil stone over diamond honing tool?
Excellent presentation! That should be the first lesson in cutting with the lathe. Regardless of the lathe you use the cutter geometry will make all difference in the quality of the work. Thank you for such a clear and informative lesson.

2nd time for me! Fantastic videos!
@MichaelKingsfordGray Wow, good one.
This is only my third. Better pick the pace up. :)

Manual dexterity is only learned through experience, however with guidance on techniques and form one can acquire mastery much quicker. For instance, if you know how the stir pancake mix you can use that same technique to mix mortar/concrete (knowing more-or-less the consistency).
Once the basic fundamental processes, techniques, and principles are learned and understood they can be translated and incorporated into other subjects than the ones which were learned from.
I see a lot of basics being missed simply because the necessary skills aren’t translated from other fields which have the same basic principles. Only if they broke it down to to simple steps and processes and used what is already familiar to them would they succeed, and quicker. Sometimes the bigger picture needs to be put aside and ignored.
40 years ago I took the wrong career path being mesmerized by electronics. I didn't recognize I had a talent for working materials back then. I've never had any schooling in metal work but everything I saw in this video made sense.
A very well produced video. The hand gestures kept the attention going.
My problem is I am into both....
Same
Old school machinist here. Why am I watching this? It is all quite correct. No drama. Good job.
I’ve been at it for more than fifty years and I agree completely.
This is absolutely solid gold. My 23 year old son is just now learning to become a machinist oh, and this is the type of irreplaceable priceless information that you just can't get in a class! Thank you so much for your contribution to the art!!! too many young kids are becoming appliance operators with their CNC machines, I was blessed enough to have learned on manual machines when I was much much younger, and it makes the troubleshooting process with a Haas CNC machine much easier.
Wow, Tony you have a GIFT of communication and instruction. I greatly appreciate you making these videos.
I just started a college level intro to manual machining class, and both my instructor and my textbook explain the tool geometry pretty well, but you, you TOT, you blew both of them out of the ball park. Excellent Video! I wish he would have played this for my class!
Tony brings the theory to real life using simple down to earth graphical illustration that wake the brain up and provides the viewer an Epiphany Moment in time where the World Stops and the Magic comes to the Light of Day.
Tony brings the theory of GRINDING HSS TOOLING, to real life, using simple down to earth graphical illustration that wake the brain up and provides the viewer an Epiphany Moment in time where the World Stops and the Magic comes to the Light of Day.
Tool geometry on cutting effect has always been more black magic than science for me although having a chance to make my own tool back in school. Thank-you so much for making it super clear! Love your videos
This is the type of instructional video i like. It goes beyond just telling you what to do, it teaches you how things work.
It has finally come to it. The ultimate consequence of watching thisoldtony. It’s still hard believe it. I bought a lathe. And I’m not even (too) embarrassed of saying it was largely because of his videos.
This is the third time i’m watching this one. The first, i was but a hobbyist handtool woodworker, who inadvertently fell asleep while watching some other, more woodworking-friendly, of tot’s videos, and woke up midway this one while on autoplay. The second one, I watched because I had seen enough of tony’s videos to understand a little bit better what he is talking about, and was honestly enjoying the technical content and having a better grasp of the jokes. Now, I’m about to grind some hss blanks. Wish me luck. Otherwise, I’ll be sending you an invoice for the price I paid for the lathe. 😆 Thanks for your great work tot! This is how awesome you are! Congrats on 1M subscribers!
I own an ancient Zyto hobby type lathe. Passed down through the family. I followed your instructions and was able to make my own tools in 1/4" HSS in no time. They cut like a dream. Thank you!
This is the most approachable introduction to the subject I've seen. I remember struggling with this for an hour in a machining class I once took, and in the end the instructor had to basically do it for me... I just couldn't understand what I was even trying to do. Now I might try to give another crack at it. Also, funny to boot. Thanks a lot!
I just tried doing this now in shop class. Came out like complete shit. Had no idea what I was doing
Wow! I have no experience with this nor do I have a clue what lathe tools are supposed to look like, but what a wonderful methodology and video for showing someone the HOW and WHY you make the tool as you do. I feel more intelligent just from watching you. Thank you for your Time, effort, experience and wisdom when making this video for us. Beautifully Done!
Man way to break it down so even a dimwit like myself can follow along! Just what I was looking for, thanks for the help!
Gunflint Designs Here, here, me too
Joim the club lol
Me too!
Probably the single best explanation about a) how to grind HSS tooling, and b) WHY to grind it that way. Absolutely indispensable, and definitely bookmarked for future reference.
I want to let you know, you are incredible. I spent a week attempting to figure out what was going on with rake angles, chip load, etc. during University, and I nearly failed the section. This actually clarified everything so super well. I know that I probably could have put this all together myself, but not nearly as well as this half hour has been. Thank you sooooo much for this.
David im still confused
Again, this video giving insight into the why more than the how suits my needs much better. I keep watching this channel probably until I have seen all 7 years of it. Thanks!
The amount of knowledge in this is amazing. These videos are just awesome.
Instructional and well laid out with excellent descriptions. This is what I have found,lately: ruclips.net/video/SAMy_hiROyk/видео.html

Tony - I agree with folks who praise your skill and talent at setup, videography and narration - you're a natural at this and your production quality absolutely delivers. Beyond that, you are a wonderful teacher and mentor - folks don't realize what a gift this is. I greatly enjoy all of your video productions - thank you for providing these great videos !
Rather than just add my thumbs up, I have to agree with arkwoo, your videos should be a prerequisite for an apprentice machinist, tool and die maker or model maker. I was a machinist and only wished I could have had somebody as good as you instruct me. I had to learn it the hard way and even as I loved what I was doing my instructors were absolutely no help. I was successful, but damn was it hard!
I've been gradually going through watching each of Tony's videos, and every time there's a new one I actually get a bit giddy. These videos are all amazing, it's pretty incredible how much I learn from each one and how entertaining they are at the same time. This guy really doesn't get enough attention in my opinion.
I can not thank you enough for the clearest explanation I have ever seen. This one video cleared all my doubts than in my class I have ever attended. Thank you so much. Thanks for the great efforts to make it easy to understand.
Dude, I love your videos so so much
You have no idea the joy they bring me
Just ground my first lathe tool based on what you showed here - 3 years after watching it. I honestly am shocked that enough of what you showed stuck in my head that the tool actually worked really well!
Another great video. I wish more RUclipsrs would take the time to produce well scripted thoughtful and humorous informative videos.
Thanks for describing all the reasons for the grinds...it's been over 40 years since Trade Shop Class and I needed the refresher. Picked up an older model Edestaal SL1000 and trying to relearn how to use it correctly. Thanks again...
This is such a great video! This is one of my favorite methods to learn - trial and error, I love that you took the time to make this video and go step by step as though you were solving a problem. I've shared your videos with everyone I know because even if they don't have an interest in machining - they get a real kick out of your presentation which is by far the best of all! Thanks for all of the great content that you produce and I realize this video is a little old... but still :D
Man. you should have been my math teacher in grade school ....you made this complicated subject as clear as it can ever be.. thank you for your time and effort.
That sort of information is the most useful thing in the world, I think reading 100 books is not yet enough to get all that info you mentioned in this video. I love your work!
That's right Mohammed
SIR! You have answered every question about tool bits & the various angles. I do no machine work & never have,
but I have insatiable curiosity about many things. Bravo ! & thank you !
Well THANK YOU.
After watching hundreds of footage on lathe cutters, I have to state `this was so easy to understand, You did a great explanation through the whole footage, 'and very well filmed,
I understood what a relief is on drill bits and after 50 years I now can sharpen my own drill bits through watching other vids,
And now ill be able to sharpen cutters etc for a lathe,
I take my hat of to you, for your time you've taken out to show us how to do this, So a big thanks'
And thank you for not using music which end up drowning over a persons voice.
For a novice like me that's a super-useful video. The fact that you bothered with such high production values and also made it funny is a huge bonus. Very many thanks.
Damn! I've watched this video already... But I have a machining process exam tomorrow and had a hard time understanding this topic. So I rewatched it. You are awesome. Learning from home due to covid, I've never seen a lathe tool in person and your video is definitely the best after searching for so long!
Thank you very much for the info and the effort made to post this. My family ran a motorcycle dealership for 40 years and we bored many cylinders in that time. My dad had been a tool and die maker years before that so we had some knowledge in our shop about cutting tools. Occasionally my dad or I would try to sharpen the cutter for the boring bar (by hand). Because of the years of experimenting with good and bad results, it was really interesting to watch your video. We eventually bought a tool with carbide inserts but we found that we could get much less chatter from our machine if we modified the tip of the insert a little. My theory was the the angle on the end of the tool was just a little different that what we really needed. We had the machine overhauled at one point and that helped some too but having the right tip geometry was key to getting a finish that would hone out easily and make for the best cylinder surface.
Hi Tony what a fantastically presented video. I have just started teaching myself how to use my new mill drill. Purchased my first bit of 1/4" tooling now I feel I can have a good go at sharpening it. Thanks heaps from a new subscriber in New Zealand
OMG The sarcasm and jokes and video edits never disappoint! Thanks so much for doing this. I am not wealthy and bought and am upgrading the dreaded Harbor Fraught Baby lathe. It does 80% of my small stuff I need but it has definately needed every upgrade I've done , A Lot. Now I am starting to do a few things and need to make bits so these vids are a godsend. Thank you.
When doing a boring operation, typically you want the tool to make chips. Long stringy shavings get caught up on your boring bar and ball up inside the work, causing scratched up finishes or breaking your cutting point. Small chips fall into the bottom of the work (tube/pipe or what have you), and just flow out of the work into your chip tray like fluid. With coolant, chips tend to flow out of a bore quite well. I've had some really far from fun boring operations where we couldn't push the tool hard enough to break a chip (due to clamping limitations), and I must say stringy shavings in a bore are a bitch to deal with.
If your tool's geometry has a chip breaker built into it, generally as long as the tool is sharp, speeds and feeds will dictate whether or not it breaks a chip. Often times, these speeds and feeds are much harder than you would want to/could even push a hobby machine.
Love the videos though, always entertaining.
Got my 50 year old lathe today, Have not even cleaned it up or switched it on yet. Your video makes me think I can do this! Thanks Tony you took away the jargon and added the fun.
This is insane. I'm getting obsessed with your videos, Tony. Can't wait for the next one!
ToT is the most informative and entertaining channel on RUclips. The only channel where I still watch every video even if it's on a subject I know I'll never get into. And now that I'm thinking of up grading to a workshop that has more than just a cheap drill press, it's the only channel where I'm re-watching lots of videos =) Thank you ToT =)
Wow. I acquired a lathe with a ton of cutters and tooling and now I know what I’m looking at. I can identify how each cutter should be used
While we may not all agree on every aspect of the advice and descriptions offered, a point that the presenter addresses openly in the monologue, this is (IMO) one of the best novice hobby machinist basic instructional videos on the subject of griding high speed tools available RUclips. Nice job .......
I let out an audible "Yeah!" when I saw this in my feed.
Povl Besser it's the first thing I learnd at school (this was not ment to be a response 😆)
Povl Besser ..i know that feeling :D
But did you change your speed to match this change in your feed?
Povl Besser I think we all did !!!!
Always the case when tony has a new video tbh..
The greatest tutorial I've watched on the subject.. explains the "why" instead of just do this.. Excellent job!!
I've yet to see anything on T.V. as good as this channel! Very good content, editing, humor ect..
Wonderfully informative video. I love the way you describe things. It helps me to understand things at a very basic "first principles" level, which is much more useful than a "here's how to do it" video. Thank you.
This video was really good. Now I undestand perfectly! Nestish-barb-wire is good, buying cutters is cheaper, and feed-rate for metal/alumnium is between 5000~7000. I'm so confident now that I'm going to work alone in my shop all night. Smell ya later
Xano Trevisan Kothe lol what
Man this was the BEST explanation of grinding tool bits I’ve ever seen!
You're subtle subliminal message of subscribe wont work on me. I already subscribed.
Dang, I saw it and I still subscribed!
I'm not hypnotized either. Though I am subbed for some reason....
You are subtle subliminal message of subscribe wont work on me. I already subscribed.
I bet people would subscribe more often if you flashed it every second. I can't stop subscribing!
This just in subscribing part 2 confirmed
Thanks very much! The way you explained this tool grinding procedure finally allowed me to understand what it is that you are trying to do when grinding the blank. You are an awesome teacher!
I work in a heat treating plant. High speed steels thermal resistance comes from the high molybdenum carbides in the alloy that retain their structure better under heat than regular ferric carbides. It's difficult to work besides a lot of grinding though, it needs to be nearly molten to be movable, and it quenches at nearly the melting point of the steel itself so if you overshoot at all or have a lower alloy than you thought you melt it and potentially burn your molybdenum out. I'm not an expert metallurgist though, I may be wrong and that's just the one variation I've seen.
Hawkeye, this is absolutely the best shop video you ever made! I'm amazed at what repeatability it has! Each time I zero it out I sit back with a cup of Joe to learn and enjoy. If RUclips ever has a VideoLympics in SHS Lathe category this vid would run away with Gold Medals! THANKS!!
Wakodahatchee Chris
I'm 76, had 2 seizures and don't take care of myself. All of which definitely affects memory. The plus side of this is movie and home shop video "ReRunAbility". It was only 10 months ago since I posted here but I didn't know that until I started a new comment. Sho nuff, my substance and entertaining rating of this video remains *YOUR ABSOLUTE BEST*!!!!
I still love it! 🥰🥰🥰
Wakodahatchee Chris
Every time I see one of your videos on my sub box I get stupid grin on my face and click it as fast as I can! Thanks for you wonderful work!
What an explanation. Charity at its highest. What effort would have gone into this. May God reward you for this. All I can say is BIG THANK YOU.
Thanks so much for the time y. ou spent explaining the various angles and how they affect the cutting process. Now I can approach my tool bit grinding with some real knowledge about how to actually grind them!
The most concise and complete explanation I have ever seen. Very nicely done.
Great video, Tony! As you know, this subject is near and dear to my heart. :)
Thanks, glad you liked it!
Your presentation here is exactly how I started out with tool bits when I knew literally nothing about lathe tool geometry. Went from trying an unground bit too experimenting with different angles.
HSS is the future .... in the home shop! Mastering, or at least getting the basics of grinding HSS tooling will save you so much money and help you get projects done faster. I know that carbide is much more efficient at removing material but you have to look at the big picture. Insert tooling is expensive .. and I'm part Dutch so naturally I avoid the stuff like the plague in the home shop.
Stefan grinds his own carbide - something that is probably as economical as using HSS, but you need to master grinding HSS first.
Loved the video, as always. Edutainment at its finest!
I agree, great video. The overlay drawing added was brilliantly done.
I've been watching ToT videos since this one was newly released. I've only just had the chance to get my own lathe and finally I can put all of this info to use. Time to grind my first HSS tool. Thanks Tony, you've taught me so much
Brilliant vid - you should have called it 'Grinding HSS tools demystified".
I learnt a great deal - very well explained, thank you. Subbed.
None of the teachers of my college explained tool geometry this easily. I was struggling understanding all this Angles. Thanks a lot ..... You are a great teacher.... You made this so simple to understand.
Awesome video! Also another example of when you dont want to "break" chips, when i work with a more expensive metal on a lathe ill try and keep my shavings in nice long pieces, especially for silver/brass/high quality steel, as its easy to collect and sort large spring like shavings rather than a bunch of tiny chips, this way you can easily recast your shavings into ingots
Tony, I don't know if you teach for a living but you absolutely should teach. Your knowledge and humor will keep even the most uninterested student engaged and facinated.
Kudos.
And if only 10% of the people who make videos had your technique, youtube would not be the vast wasteland of shameless self promoters that it has become.
Those C shaped chips are called 6's, except for in Australia where they're called 9's.
Andre Gross is that because they're upside down

What black magic do you use to turn your text down under?
Dont they call em "e" in US ?
I took a Metal Cutting class back in engineering school, they let us play with lathes, drill presses, and we made our own cutting tool with HS Steel. Your video brings all that back. It was a fun class. Great video BTW, Liked and subscribed.
I really enjoyed the video, but there is one thing that bothers me alot... Why am I watching these kind of videos, when i'm nowhere near a lathe or high speed steel or anything related to this?
builds survival skills. :)
Szabó Arthur
Tony is just that good that he can draw in people that have no idea or interest in machining :)
I spent years in this realm. It's not that you don't have a lathe. It's that you don't have a lathe YET.
It would help your from been screwed by a machinist, when you carried a project to be done. Like going to a Auto Mechanic and he tell you $10. to change a radiator cap because it requires some technical work to do so. Respect.
I was working with some hot rolled steel bar from a big box store that doesn't machine well at all with indexable carbide insert tooling. I re-watched this video, and proceeded to dig out an old 3/8th inch HSS lathe bit I'd fumbled around with grinding a long time ago. I quickly spotted how mine differed from your example and ground it to match yours - minus the chip breaker. Honed the edge and gave it a try. While the mystery metal HRS is still some crappy stuff, the nice sharp HSS cuts instead of plows, and the rounded tip leaves a far and away better finish than my TCMP 21.51 inserts tooling could get on my little benchtop 7x12 mini-lathe. Followed up with a bit of wet-sanding with 400 grit and got about as nice a finish as is possible with this metal with minimal effort.
Your intention to help people certainly paid of well for me today. so thank you very much! Your videos are simply outstanding and this particular one has gotten me back into wanting to grind my own tooling again. I think it is time to make up some proper adjustable tool rests for my cheap grinder and do things right this time around. Thanks for the inspiration...!
Shout out from Australia, new to the industry and love your vids, classic mate
I don't know how it happened.. I didn't use to have any particular interest in machining past an 'oh that's neat'... But now somehow I'm 12+ hours into watching this channel and now know more in-depth details about this world than I ever thought a human who doesn't do this for a paycheck should know.
Very fascinating. If you get sick of doing this stuff, apply for a comedian position. Great comedic timing. I wish I could talk about leatherworking the way you talk about relief angles.
I use to have a family, wife, kids and a little turtle, my life did a 180 turn since I discovered rake angles, curls and chip breaking AND I don't even have an laythe ! I love you dude, keep it up.
The best explanation for the need for a single point cutting tool that I have seen as well as a clear explanation of how to create it.
Hi mate. I think you kicked a lot of the other grinding videos out of bed here. Although, maybe not the nicest tool to look at, it explained all I liked to know. I particularly liked the pencil analysis. All the little gages kept it all light and digestible, for me at least. Thanks teach.
Tony:
I forgot, as always your instructional talks are excellent both in content and the visual display. You convey the "Point" in a very concise and graphic manner.
very good video, probably the best on the tube. If I was still teaching shop I would be asking you for the educational rights to it.
Thanks Billy, that's quite the compliment.
Newby here, appreciate the humor, good for my sanity quotient, reminds me I bought a metal lathe to have fun with it. Luckily I have ample time to waste, being a retired widower. Many mistakes buying stuff on the internet! A watchmakers lathe with zero accessories and trying to purchase split wire chucks, three tries and no match for the lathe, no name on the lathe that I can read, written in Chinese.
I ordered another lathe hoping I can manufacture parts for the watchmakers lathe. I like to tinker!
This is an expensive hobby but I am persistent. I have more time and money than good sense. I love your videos!!!
Wow, before I knew it, I had already gotten to 24:18. That is a really smooth thing that you did. The surface finish is like looking into a mirror.
I've been working as a machinist for about 14 years, and I came here to brush up on some basics and found this very refreshing. In a modern workplace with CNC lathes, we rarely grind our own tools. 99% of the time we buy them from other companies that grind them using CNC. Great video! Hand grinding is a very important skill that is becoming lost in the modern world it seems.
Did I hear you right? We're you suggesting Mrs TOT's chocolate chip cookies are harder than aluminum?
Another GREAT instructional video. Thank you! Joel.....
How do you think they machine carbide inserts? The cookies are not just for aluminum.
That's why TOT sounds so frustrated with chip breaking on aluminum, but also how he built up a wealth of knowledge on tool design. Trying to carve chocolate chips out of Mrs T's cookies is no joke.
As a lathe newbie and an old fart, this video clearly explained the 'black magic' behind the cutter angles.
Thank you very much, you have a new subscriber.
“That sounded splendid!” 😂
I've kust come back to this video after first watching it years ago. I'm in the process of grinding some new tools for my day job and this video is an absolutely superb how-to guide
does the "subscribe" or "like" grinding wheel leave a better finish? ;)
rdavidr no but the my eyes are up here does
I would say "better" finish as much as "happier".
Don't forget the 'My eyes are up here'.
The chip breaker/controller grind you finally put on that tool completely masked the rake angles you ground into the top of the tool. I know; instructional, exploitative video, but just saying.
Thanks for presenting all that and especially starting from a square tool and developing each feature that progressively improved the tool's cutting performance. Very enlightening.
"I want to show you what the tool sees." Subscribed!
This is the best lathe tool grinding tutorial I've seen yet (and I've seen a bunch). Explaining the actual function of each facet is very helpful. Good job!
At 5:45, I've always called that "chatter." The chatter marks are seen in the corrugated pattern on the OD of the cut area.
At 26:59, I wanted to scream "GET BACK!" Positive rake into a grinding wheel? Yikes! I got the same scolding after doing the same thing, then talking about the result. My result was that the tool caught on the wheel and shot toward the concrete floor, leaving a divot. It also took a chunk out of the grinding wheel and ruined the balance. Made quite a noise, followed by some astonished cussing. I was lucky not to be injured, and in retrospect, surprised the wheel didn't come apart. The wheel was shot, but I kept it for a while as a reminder.
If I were to attempt the same grinding, I might use a Dremel with a cutoff wheel and clamp the HSS in a vice. Something - ANYthing else.
All ranting aside, this is a very informative video, especially regarding chip breakers. I struggle with them, too. If you think 6061 aluminum is bad, consider 304 stainless without a chip break. Lots of sharp razors flying around. Ask me how I know...
Best explanation ever, never had to rewind to try and understand. 100 thumbs up. You focus on the topic and keep the humor to a minimum. Well done I am now a subscriber
Old Tony
You skipped the part from 1880 to 1906 when Frederic Taylor invented high speed steel, developed the Feed, Steed, Depth of Cut tables and Flood Coolant necessary to use it to best advantage, then published his findings in his book "On The Art Of Cutting Metals" which is available from Amazon.com
otherwise pretty thorough history.
You mean "Frederick Winslow Taylor" "On the art of cutting metals"
Yes
Great video! That’s the first time anyone has ever explained the reason for the cutting angles to me. Thanks again.
If you did not notice them, go back and read the secret messages on the grinding wheel. Very subtle Tony!
I saw that too where the NORTON should have been.
This is an outstanding instructional video. One of the best If seen on the internet. at 14:40 when you faced the tool to the camera as the work see's it. That was brilliant. I wish my instructors would have had a video like this. Thank you for such a great video
Super informative, took a lot of the invisible magic away. What grit/material grinder wheels are more or less ideal for this process? Do you prefer oil stone over diamond honing tool?
Excellent presentation! That should be the first lesson in cutting with the lathe. Regardless of the lathe you use the cutter geometry will make all difference in the quality of the work. Thank you for such a clear and informative lesson.
Video so good I actually appreciate getting schooled! Love the vid! Detail, humor and info is awesome!
For a beginner, this is the best video I've seen on RUclips. Thank you.
My tooling always looks and sounds like the very first pass!! LOL Great vid, I think my 10 inch atlas will thank you!
The illustrations to explain what you've done, or are going to do, are highly informative. Thanks!
