When I was a kid I couldn't afford to buy milling cutters so I started making d bit mills. I found that if you insert some shim under one of the jaws in your 3 jaw ( I couldn't afford a four Jaw and collets were something I only ever saw in catalogues and books) then you could generate some form relief. You've just got to mark out the high point before you mill. (or in my case back then file ) the flat. Weirdly 45 years later I am still making these tools to overcome emergency problems in a hurry. Keep up the good work the videos are fantastic. Thank you
If there's any kids watching... auctions and scrounging are the answer. I got 200 (yes, 200) sets of geometric die head cutters for £50, a pair of Herbert precision drills for £50, a Parkson 2A horizontal milling machine for £50 (bit of a theme developing here). I passed on two pallets of 4, 5 & 6 morse taper drills (maybe 500 drills) for free (help yourself son!) because I knew I'd never own a machine big enough to use them. That was before Ebay of course. Wish I'd taken them now. I got a box of about 50 rotary cutters for £30 when the Cincinnati main dealer closed in Peterborough. My first lathe was a Colchester Student for £200 (same place I got the Parkson). I've outfitted a very decent workshop for next to bugger all. Everything dates from the 60s & 70s and works fine. Pickings aren't as good as they were 30 years ago but you can still buy decent lathes, mills, drills, etc if you watch local auctions and just nosey around machine shops. I've been offered very decent lathes and all sorts of other stuff for free. Scrap bins. Never pass a scrap bin. Always be polite and offer cash or a bottle of something.
This video just inspired my semi-functional brain to come up with a "solution" to a very tedious boring operation required to complete a project of mine that is at a stand still and has been bothering me for some time. Thank You!
This collection of videos are like therapeutic to me. Watching the precision, the amazing footage, and listening the descriptions, simply relaxes me, and makes me forget about my stress...
Your projects are amazing. I now see why some of these things cost so much money. The amount of time and work that go into a project like this is phenomenal.
Yaaayyy... a new Clickspring video. Been missing them. Always thoroughly impressed with your work. Both on the actual topic of the video, as well as the production value of the video itself. One thing that really speaks to the quality of the presentation is that the viewer is left with a feeling that one could do it oneself. Even if I'm painfully aware of the fact that I have several years of practicing ahead of me if I ever dream of repeating anything done in your videos =) Thanks again for an excellent video!
We have been using D shape or half lip cutters on our 3d engraving machine for over 40 years. About 30 years back I came across a design where I can give a relief to the cutting edge. So we made an improvised cutter grinder where a swash plate mechanism has been used for the relief. But this video is just awesome
Such a craftsman, Chris. These videos are an absolute joy to watch. I'm hanging out to see your new videos more than my favourite TV shows or movies. And I'm glad you're sharing some home-grown Aussie intelligence, engineering and easy-going nature with the world. That's how we roll. Certainly the quiet achievers. Keep it up mate.
Another well made tip. It's good to see someone explain D Bits well as they make excellent reamers for jobs that require a reamed diameter on a flat bottomed hole. I recently made one for a block of aluminum that needed a 4" long cartridge heater. A D bit made from drill rod was the perfect tool to ream .3750 clear to the bottom of the 4" blind hole. Love the videos, keep them up!
As a tradesman Toolmaker from New Zealand, it often saddens me to see tricks like these, as well as things like spade bits, hand made fly cutters etc fall out of favor in toolrooms, the basic sort of things i first learned when i started my Apprenticeship are almost becoming forgotten tricks of the trade. Really awesome to see someone demonstrate them in such a clear and concise fashion for the home engineer. And i have to say it, i'm genuinely jealous of your meticulous attention to detail and finish quality.
There's nothing like making your own cutting tools for the shop. Those single flute d-bits are awfully handy and do a great job when properly made. Nice work.
Have to say that your video quality is excellent. Too many RUclips videos are spoiled by poor camera work. Yours are amazing and adds to the dimension of the quality of the work with the tools.
I have never been really "interested" in milling..... not that i had anything against it, just haven't had much exposure. After obsessing over your videos overnight for the past month... i can really see the possibilities that learning these skills could open. Now i just need money for the tools... Thanks for making these videos!
Just found this excellent video. I have been making and using 'D-bits' for metalworking for years, first inspired by Bogs. Your video adds improved techniques. I plan to make several as you have shown for the CNC router I'm building. Thank you for sharing your technique, well done!
Fell in love with the video quality, style, accent and attention to detail in first video that I watched :) Now I can't have enough. Thanks for excellent content and hope you won't stop for a long time.
+krneki44 Thanks for the encouragement mate, will certainly keep doing the videos. Some great new projects lined up for next year I think you'll really enjoy :)
I love watching the tool making videos. Especially when the tools are as nice as these. Whenever I score a mixed lot of tools the first thing I look for are handmade/customized tools. It's a bit like a mystery novel trying to figure out who made it, when they made it and why they made it. You do fine work, sir.
Clickspring Great to have something (and someone!) of this caliber on RUclips! I love seeing your work: a combination of all my passions, designing, making, and clocks, machining, art and moving parts! (And thank you. :D)
Excellent! I started making one last night, based on a sketch in an old lathe book, but I couldn't figure out the purpose of the 'recess behind the flat'. Thanks for explaining. Cheers Paul
Hello Chris: @3:47 you illustrate a relief angle. But separate from feed speed and depth of cut would you not avoid that angle when machining brass? It seems that that angle would risk climbing or pulling on the brass. Much in the way you eliminate the positive rake on your drill bits in “Spare parts #7 - Modifying A Twist Drill For Drilling Brass”. I was presuming that that was why you stayed .01 of a mm shy of the center line to asure a negative rake. Or did I miss the point entirely?
+halnywiatr The relief angle is there for a different reason to the rake angle. A relief angle is typically always required to ensure that the cutter doesn't drag on the work, regardless of the material being cut. It's strictly a clearance thing. The rake angle is the angle on the 'front' or top of the cutting edge, that can potentially cause a cutting tool to 'dig in' as you mentioned. Think of it as 'the surface that hits the chips'. Interestingly, D bits are essentially always zero rake, yet will cut steel almost as well as brass or other soft materials. The +0.01 is more for assuring the opportunity for future sharpening opportunities, before the flat is ground below center.
+Clickspring The debate in my head is that that is true for a plunge cut. But in milling perpendicular to the axis of the D-bit, the fight between “climb” and “standard” might be exacerbated by a relief angle. That, however, is only an interesting mental exercise. What is important is that you have shown that it works without a relief angle in brass. Thank you for that empirical evidence.
+Clickspring It is always a pleasure Chris, I love your vids! I haven't moved yet due to economical situation. I'm planning to do it in mid April. Cheers!
I just tried making one myself! I it sort of worked for me haha. I think I either removed too little or two much material when making the flat. It seems to push the material rather than cut it. I'll have to head back to the shop and make another one. This time I'll be more careful. Thanks for the video!
Hi Chris, your job is amazing, congrats! I have a technical question to you, if you can answer, please. About Boric Acid + Meth Spirits, how much of each one do you put in? I mean, proportionality? Meth Spirits is a kind of alcohol? I'm sorry if is not written very well. Another doubt is in 2:20minuts, what is the liquid inside the glass, that you put in, something to clean the tool?? Thank you very much. I am Andrés Oscar, from Argentina. Regards!Thank you!
I generally mix the boric acid until a stiff paste, yes methylated spirits is a kind of denatured alcohol. 2:20 is a generic compressor oil for quenching, recommend this book for heat treating: amzn.to/2IdTQLw - Cheers :)
Hi Nice video. Thanks for sharing. We used Drill Rod, Silver Steel previously for making cutters without getting adequate glass hardness. Need to re-think and re-do our Hardness technique. aRM
I am 57, but when I grow up I want to be like you.
This is my favorite part of machining: when you need a tool, you just stop and make one! Very empowering.
My issue is I've been making tools to make more tools to make tools. That I've forgotten what I was making to begin with.
When I was a kid I couldn't afford to buy milling cutters so I started making d bit mills. I found that if you insert some shim under one of the jaws in your 3 jaw ( I couldn't afford a four Jaw and collets were something I only ever saw in catalogues and books) then you could generate some form relief.

Seriously this is the best quality content on youtube
I've learned a lot from this channel. One of the most valuable ones is all these shop-made precision tools, like this and the pivot drill.
This collection of videos are like therapeutic to me. Watching the precision, the amazing footage, and listening the descriptions, simply relaxes me, and makes me forget about my stress...
+alex akkers Terrific to hear that Alex :)
Great tool. Cutters are always expensive so making simple tools like that are a bargin. Thanks for sharing.
Your projects are amazing.
I now see why some of these things cost so much money. The amount of time and work that go into a project like this is phenomenal.
I know absolutely nothing about machining (though I watch videos like this almost religiously), but your videos have the best payoff. The BEST.
Jesus christ, the quality of these videos is amazing. The video, the bacground music, the narration, everything fits so well. Incredible job man!
+asda89 Thank you for watching :)

you just blew my mind, great video. I have always thought this type of cutter was only for glass cutting/drilling......
I bet you make a wicked fixed blade knife
Wow this is my first video and I am already really hooked! Amazing!
Awesome Ian, great to have you watching mate :)
Nice. In boring head at 4:30. Using boring head with profile cutter ! You figure out a lot of shop solutions.!
Excellent! I started making one last night, based on a sketch in an old lathe book, but I couldn't figure out the purpose of the 'recess behind the flat'. Thanks for explaining.

Thanks for showing you are gifted.
This channel is awesome. I can only dream of doing this kind of manufacturing. I have the skills and knowledge but lack rescources and finances.
Another impressive video! I was wondering about the relief angle so I am glad you mentioned it :)
Yeah... New Clickspring videos!!
Brilliant finish on the clock surround at the end, nice one.
If you like his videos disable adblock if you have it. Work like this needs as much support as possible.
+Valtra103 Thank you mate, I very much appreciate your support :)
Clickspring
I like to make stuff myself, so I know how much work you put into these videos :)
Fantastic work and you make it look so simple !
Good and sencible presentation, well done.
Yes clickspring updates!!!!!!
Great stuff Chris. As usual, beautifully videoed and most informative. Hope the clock is in good health! :)
+ChrisB257 Cheers Chris!
Merci beaucoup pour ce beau travail
mind blown ive never seen one of those !!! great video !
Just excellent videography. Many thanks.
It may have been mentioned already, but I use a toaster oven and oven thermometer to temper and I get pretty accurate results. Great videos!
+Nick Watson Thank you for sharing Nick, and thank you for watching :)
Thanks Chris! Always worth the wait!
Wow! Perfect work
Nice work! I’ve learned a lot from you! Thank you!
Can you elaborate on the angles used for the lathe style D bit reamer.
Thanks !
best information I've come across bravo man
+Darren Birkbeck Cheers Darren, thanks for watching

Good idea , thanks guys
Hello from Indonesia
Awesome trick for beginners
Hi
Nice video. Thanks for sharing.
We used Drill Rod, Silver Steel previously for making cutters without getting adequate glass hardness. Need to re-think and re-do our Hardness technique.
