You just showed me how to correctly sharpen drill bits! Never realized that there is a technique to properly get the drill square and sharp! Thanks so much for explaining this! I've struggled with this a long time, can't wait to try my hand at this now.
Thanks for watching and commenting. Appreciate it!
Immensely useful. You’re downloading the most superb essence of your intelligence and experience, so generous, so useful, so very much appreciated. Thank you so much. Cheers, Will
Thank you Will. I'm happy that our videos are proving to be useful. Appreciate your comments!
This was one of many skills I was taught in Jr. High shop class in the 70s. It seemed easy then but now when I try to free hand a drill its a challenge. Its great to see someone with skills!
Allen, you have to keep practicing! Helps to have very good eyesight too. Thanks for watching..
Great Video! The only drill sharping video necessary.
This is the best drill sharpening video I’ve seen. Thank you, Mitch & Paul! Wishing you both well!!
Right?
You know it's right when you see swarf coming from both sides of the drill as it goes in. :)
Great to see that you are out of the hospital and back home again Paul!
You and Mitch together have produced one of the best, most informative and entertaining RUclips channels on bike and workshop subjects.
Best wishes.
Thank you Ronald! 😉
Ronald thank you for the update with Paul’s health. I’ve been checking the comments virtually daily. I’m curious, is there another area to look at for updates on Paul’s health?
@@davidsnyder2000
Try the about tab on his you tube chanel. There you can find links to Paul’s othet sites
I love how patient you are in your explanations you’re a great teacher keep doing what you do you’re amazing
I taught Framebuilding 101 at the University for almost 10 years. That experience really helped in the videos.
Yes your are right, I love how patient he is when explaining the process. I’m working on how to do that my self. He is a great example of a humble craftsman. 🤜🏽
@@NestDesigns210 Thank you so much 😉
Best video I've seen on the subject. Clearly tons of experience. Solid filming and great detailed useful explanation. Wish RUclips had more content like this! Thank you!!
Thanks Alex. Yes, I have been making things in my shop for many, many years now! ...
Thanks for reminding people to stand to the side when starting up a new wheel. That's a safety issue that many people over look. Great video
Thanks Dave.
It’s always a bad day when they pass right by you and you realize you never could have moved in time.
The best explanation ever, thank you!
Thank you very much!
Thanks Paul and Mitch love the attention to detail and what you share with us. Go well.
Thanks so much for this. I’ll have to watch this several times but I finally feel up to trying to sharpen 40+ years of blunt drills.
Andrew, you are welcome. Just take your time and have a bit of patience!
@@paulbrodie it all looks possible and lacking in mystery now. I’ll be giving it a go soon.
Right on!
Outstanding Paul, well worth the wait...thank you, another brilliant technical video, your a legend
holly crap Mr.
Brodie, these bits get me so frustrated ,tks for the tip.....!!!
Thanks Dell.
I'm very sorry to hear that keep your chin up we need you back in the shop 👍
Thanks Peter! 😉
Good Morning you two. Thanks for the tip!
👍 , , , my grandfather was a machinist , , , started out during world war two , , , became a machine shop teacher here in Sault Ste Marie , Ontario in Canada at the Sault College , , , i took machine shop all through high school and at the college , , , i really like watching your channel and the things you show and teach , reminds me all the stuff i learned and the the things my grandfather showed me. 👍
Good to see you are replying to comments Paul, you will be back educating & entertaining us when you are ready, of that I am sure. Beaming lots of positive energy from the UK.🤞
Thank you Lodge, appreciate your support 😉
Helpful, thank you!
Good morning and hope you are doing better. I also sharpen drills by hand. You know when you're good at it when you're fellow mechanics ask you to sharpen theirs. Now retired, I have my neighbors asking to sharpen theirs. There is something meditative in the process and enjoyable. Blessings 🙏
Making the world a better place.
Excellent work, thank you.
Thanks Bradley!
Took me back over 40 years to being an apprentice in the machine shop and being shown how to sharpen drill bits. And truing the wheels. Thanks for the memory Paul.
Thank you. I'm glad I had that experience in machine shop when I was young.
Hi Paul. You are perfectly teaching, thank you so much...!
Prashant, thank you very much!
Thank you for sharing your knowledge with the world.
And thank you for watching.
Sorcery, absolute sorcery. I will watch this one easily a dozen times. Awesome Paul ,thank you.
Technique, not sorcery! Thanks Glen.
Very informative guys, thanks for sharing. My father and two brothers have all had back surgeries already (degenerative disc) and I also have difficulties with mine from time to time so I can understand where your coming from. Hope you feel better soon.
Great stuff as usual. It’s very rewarding to hand sharpen a bit and have it cut easily with even swarf.
Miss you guys. Hope all is well!
Thanks. Mitch and I will be back after I finish my healing process.
This is the best drill sharpening video I’ve seen
Well that is a very nice comment. Thank you very much!
I have binged watched every episode now twice. Nope, couldn’t find Mitch. Reading your responses gives me hope that things are going well and getting better. We are waiting for your triumphant return as I need a little inspiration to get back in my shop.
Not to give anything away, but the is a very small possibility you may be seeing a little more of Mitch in the days to come! Thanks for liking our videos. Mitch and I appreciate viewers like you 😉
It is amazing how clear your explanations are and how well your video makes the study clear and simple. Thank you so much for sharing.
Thank you Randolph. Glad you liked our videos. Mitch and I keep trying to do better! 😉
Your sharpened drill sounds nice as it goes thru the piece of aluminum.
Thank you for sharing.
Paul thanks for the update on your heath issue. Hope you are better soon.

This is the best drill bit sharpening video I’ve seen, many videos I’ve watched do not show you close ups of the angles, thank you for uploading this video it’s now in my saved list.
Thank you Frank. Appreciate your comments!
Hoping and praying your both doing good….especially Paul. I hope your healing and energy are on the upswing🙂🙏
One thing that wasn't discussed in this video is head on bit geometry. When you look at a twist drill bit head on the chisel point ( that's the bit in the middle the web) will have an angle in relation to the cutting lip angle. There's two cutting lips one on each flute and they both have to be parallel to one and another. Go look at a bit. If it's sharpened right those cutting lips are parallel. When they're not even they're not parallel. That's not good. You need to keep grinding until they are parallel. Otherwise you'll drill oversized holes. The bigger of the two flutes will swing wide. Throwing two chips is a sign you have an evenly ground bit. If they're not even one lip will cut and one won't. A large part of learning how to sharpen twist drills is studying the geometry. Which in practical terms means really looking at a drill bit and seeing why it cuts. If you make the bits you sharpen look right they'll work right. Paul covered heel relief but he didn't cover parallel edges. A twist drill are chisels in the round. That's how they work.
That's true. However, when you keep track of cutting lip length and angle - because of it being a twist drill - you will be pretty darn close. You develop the feel and chip formation can be checked visibly.
Going one step further, you can put a micrometer on the mill table and check the height of each individual flute. An experienced machinist will keep a tolerance of 0,05 mm, but this will of course grow the more you sharpen the same drill.
@@valkman761
if you can hand grind a drill to within two thousandths of an inch ( approx 0.05mm) you are a god😂
When hand sharpening achieving perfection is all but impossible , we can get close but if you want it perfect use a tool and cutter or D bit grinder , i prefer 4 facet sharpening on anything over 10mm 0r 3/8 inch and anything under is either hand sharpened or replaced . I have yet to find anyone on RUclips that shows how to sharpen a number 80 drill !
@@ianbertenshaw4350 Sharpening is not the same as grinding a drill bit sharp from blank as Paul here does. You can dress the edge and here's where the 0,05mm comes into play.
"chisels in the round" ... I'll remember that.
Combining your expert knowledge with a flawless video makes a fabulous teaching tool. Paul, you are an exceptional teacher. Thank you, and keep up these amazing tutorials.
Thank you Paul.. really appreciate you taking the time to pass on your knowhow and experience.
Priceless.
Cheers from Wisconsin
Jason, thank you kindly.
Thank you both, that is the best "how to sharpen a drill bit " that I have come across. I have always known the basics but you have clearly and simply upgraded my skillset. I have subscribed. Thanks again
Thanks Roy.. I'm glad you found the video to be helpful...
Fantastic 🙏🏼
I very much appreciated this. Thank you.
Thanks John. We appreciate you watching and commenting....
The best, thank you.
i can just listen to you all day you made me feel so relaxed. the world needs more people like you. thank you very much Paul. your a legend with the gift of the gab. i am now subscribed and will watch all your other videos at my earliest convenience.
Miss seeing your videos……your still in my prayers Paul❤️🙏😐
Thank you David. I appreciate your support very much 😉
It took me a lot of time to learn how to sharpen a bit by hand. I got tired of buying drill bits. I finally used new bits to learn the angle, then put them in a drill press to test them.
Learn on big bits first and that will help you.
I finally mastered the process.
Congrats! Knowing how to sharpen a drill bit is a great skill to have...
this is great , the camera work and explenation was very well done . thanks so much
that was amazing....it was like a one to one personal tutorial...
Thank you. You are very kind!
Best drill sharpening video I've seen. Now I think I can actually do this! Thanks!!
Glad I could help! Thanks for watching.
That was such a good explanation. Thanks Paul, it explained parts I’ve struggled over, so I’ll be watching again, and giving it a go. I have too many blunt drills and this video will help (has helped) a lot. Thanks again. Les in UK
Thank you Les.
Best wishes Paul from England, Be Lucky.
Thank you Lodge. I will try to be as lucky as I can 😉
@@paulbrodie 🤞❤️
You taught me something again. Cheers Paul and Mitch, always informative and entertaining.
Thanks Dave.
Patient and perfection 💯💯💯💯❤️❤️❤️❤️❤️❤️
All the best and positive waves to you!
Thank you Grey Beard. We appreciate your support! 😉
Excellent! Thanks for sharing your knowledge.
And thank you for watching!
The world is on pause, waiting for You.
We are expecting You to come back stronger, better and with a good fit. 💜
Thank you Jim. I will do my best. Paul 😉
Excellent. I have struggled with this for years. I bought drill sharpener electric things and they never worked or I was using them wrong. This is the most comprehensive, clear, concise explanation I have ever seen. I have bought numerous bits just because the old ones were dull. Thank you!
Thanks Bill. Glad you found value in our video...
Extremely informative video! Thanks!
Greetings from Ukraine!
Hello Ukraine! Thanks for liking our video...
Awesome Paul, thanks for putting up this video. Your explanations were great, easy to understand 👍
Hi Paul, Thanks so much for your entertaining and educational channel. We all hope you can overcome your injuries soon. Early in my Electrical Trade apprenticeship 50 years ago I was taught exactly what you have shown in this video. I have sharpened all my own drills and everyone else's ever since and is a great skill to have under your belt. Greetings from Australia.
Thank you Australia!
this is the best visual lesson for drill sharpening!!! thank you!
Thank you 😉
Hope you get feeling better man. Take it easy and heal up 🤙🏻 miss seeing the videos but praying for a quick recovery for you.
Working on it for sure!
Thank you good job.
Great explanation, thanks. Nice bikes in the background.
Yes this is the best drill sharpening video I’ve seen too. Very informative. Thank you for taking the time to make this video for us.
Brilliant, thanks so much for the in-depth explanation and techniques.
Thank you Allan...
The best drill sharpening video in the world, I did my fitting machining apprenticeship 30 years ago in Sydney and I was lucky enough to have an instructor who was very much like Paul. Made me a better man and good tradesman :)
Thanks for sharing. Very nice comments, Murray.
thank you for taking the time to really explainthr bit . good job sir i understand everything you explained.
Thank you Stosh!
Awesome instruction.
Thank you Tyler....
Love the Peter Counter! Keep it!
Thanks! Will do!
Great tutorial on drill sharpening, 👍, the best I have seen on RUclips, thanks.
Nice comment, thank you.
You're a great great teacher Paul. Another excellent video. Learn with you is great. Thanks a lot. From Buenos Aires, Argentina.
Thank you Dario.
Thank you that was more informative than I ever could’ve imagined. I now know that I can fix my grinding wheel from being uneven, thank you.
Thanks for watching!
Thanks for the subtitles. Thanks for the knowledge. Очень полезно.
Thanks for watching.
The best video explaining on how to do something with some much detail. I love it. Thank you, I have learn a lot
Thank you very much :)
This is the best drill sharpening that I have seen , many thanks
Thank you Hossein. Appreciate your comment!
When I was a young lad I could sharpen drills as small as 1/8th inch by hand. Now that I'm in my 60's anything smaller than 3/8ths goes in the Drill Doctor box. I have always used a guide when sharpening, felt that would be more consistent than hands alone. I never thought to use the single point dresser. I've always associated those with precision machines like surfacers and valve grinders.
excellent info! national treasure
Thank you very much!
Thanks Paul, Ive been sharpening freehand for a while , but badly! Now I can see what I need to do to make a better job, Im thrilled👍🏼👍🏼
Thanks Andrew. Sharpening is a learned technique so have a little patience too :)
Hi Paul & Mitch,
Great demo and explanation on the drill bit sharpening. My college machine shop teacher didn't explain it anywhere near that well! Thanks again!
Thank you Tom.
Nicely done. Just the way I was taught 40 years ago. Would like to add, that switching to an aluminium oxide wheel will give you much better control of how much comes off each pass, and a much better finish to the edge.
YES
Excellent
Thank you very much!
That was very informative And I believe I might give a go at sharpening. Thanks for sharing your knowledge Paul.
Thanks Carl. Give it a go. Getting the hand motions right is important and I think you can do it 😉
Although I don't understand English, with the help of Google translator, which is not very good, but with the images of your movements and also the good placement of the cameras, I understood the explanation perfectly. Thank you very much for sharing your knowledge, greetings and see you soon. 🫂🫂👏🏿👏🏿👏🏿👍🏿
Excellent explanation! Thank you for sharing your knowledge & skills.
Finally somebody on RUclips that actually knows how to sharpen a drill bit. This guy is spot on the angle really doesn't matter what is important is to make sure that the leading edge is higher than the trailing edge and it will cut
Thanks for watching! 😉
Hello Paul, how’re you doing? Everything good or on a good way with your recovery? Wish you all the best and I stay tuned for your next videos! 👍🍀🌞
Great video,
all ways found drill sharpening one of those things that looks so easy when someone like you does it, but goes all wrong when I do it 😉
Will practice with your tips and methods. 😎👍
Really clear, informative and detailed explanation of the subject. I've recently discovered your channel and as a long time mountain biker and a woodworker I absolutely love it! Especially your chilled method of teaching, I know a pro when I see one. I picked up a few good techniques here, usually I put a sort of micro bevel then the rake angle on my bits which works ok but I can't wait to try out your more fluid motion. Thank you Paul!
Once learned, it is so easy to get a bit back into shape. Nice video Paul, cheers!
I don't know if I'd call it easy. I'd say it's more like riding a bicycle. Once you've figured it out then it's not so hard to do. But yeah if you're using twist drills then do learn how to sharpen them. There's a lot of knuckleheads that just throw bits away when they get dull. Or they continue trying to use the bits even when they're dull. It's sad.
Thanks 👍
Suffering from a bit of separation anxiety from an absence of your videos and when I check to see what's up I find out about your bad news. I can't offer any wonderfully wise words of comfort other than to say that I'm truly very sorry and that I hope that it all works out well for you and that you will return to full and robust health. I'm sure that your RUclips family are all rooting for you and wishing all the very best for you.
Thank you. Yes, I am working on regaining my health, but it is going to take some time. Really do appreciate all the support and good wishes 😉

Very good video explaining how to do it thanks for your time
Thank you Ron 😉
Another amazingly well filmed and documented teaching video, thank you, Gentlemen. Missing seeing you guys on RUclips, hope you are recovering well Paul.
Thank you Shane! It was not easy showing how to sharpen a simple drill bit. I am slowly getting better, and we hope to resume filming possibly in a few months time 😉

Mr Brodie.Your years of experience shine through.This video was an absolute pleasure to watch and understand.Keep up the amazing work..Thank you,from Ireland.
Well that's a very nice comment. Thank you very much!
As a old shop teacher I would give you a A+ on your demonstration and expatiation. It was the hardest thing to teach any body to do.
Thank you.
When I was 18 and went to work in my first machine shop, the owner asked if I could sharpen tool bits. Of course I said "Sure". He took out a drill bit, ground the end flat and said "Sharpen it". I did. Been doing it by hand ever since. Great video Paul!
Thanks. Another good story!
Thank you for the class on drill sharping. GREAT tip on standing to the side of the grinder when starting a "new" wheel be it a brand new one or just a new to you wheel.
Thanks Tom.
Thanks sir, I fixed my dull bits and now they are better than new.
Excellent!
Very impressive putting the split points on there I just found your channel a while ago you’re amazing
Ernie, thanks for finding our channel :)
Good work 👍
Thanks Much.
