Making of: Small precize lathe tool out of broken drill bits [M4 internal thread cutting]

Hy There,
I use DORMER A117 HSCO drills in this video!
In this video i'll show you how i make super small and precise lathe cutting tool, i just make a simple holder and grind broken dill bits into usefull cutting inserts
there are lot of option to grind different shape of knife by your needs, i just make a few basic one like for turning, facing, boring, internal turning and thread cutting.
i use 3.3mm drill bits so with this insert i can cut M4 internal thread.
This tool is really very usefull and alsmost free to make

Thank you, what a terrific teaching video. I’m a 58yo beginner after many years working with timber and I’ve just bought my first mini lathe so this is really helpful for me, thank you

[@ChrisBrown-dy8ts]

Nice job, I make all 29 deg, acme tool bits out of HSS centre drills old slot drills and old Carbide milling cutters.

I've been saving all of my carbide end mills from my CNC router and never knew why, just didn't want to throw them out. This is PERFECT! Thank you for posting this.

Thanks for the useful info. I have just tried it myself and am very impressed!

[@fuchsmode]

Nice! I thought you'd just grind them on a bench grinder, but I didn't expect that you'd grind the tools on the lathe. I think I'll try to make threadmills and custom endmills that way. Thanks for sharing.

[@nathaniellangston5130]

Wow! This is pretty amazing! I hadn't thought you could actually get that kinda cutting tool geometry from just a grinder on a lathe!

[@saartal4524]

Wonderful project and tools made... Very creative. I may use that...
A life saving tip: cobalt drill bits and carbides are dangerous - use a respirator if you gring these.

Thats a new life for broken drill bits

Awesome idea! Thank you. I needed a boring bar for very small holes, and this looks like a perfect solution! (Plus I like the idea of mounting a grinding tool on the cross slide. ;)

New to your channel from another of your viewers we like your channel because your work is small metric and that is what we do in America, great use of the Proxxon The seed oil type I did not make out it does a great job today I use cold bluing for my surfaces. Nice video teaching and thank you for making them.

Looking at these lovely tools compared to my awful attempts at making d-bits.... nice work!

[@leerogers6423]

Nice work. A man after my own heart , waste nothing. If you have a small lathe grinding your own HSS tools is a must. If your having finish or chip controll problems with insert tools try HSS.

[@TheRainHarvester]

This is a great topic. These days, before throwing anything away, I always ask, "what is this made of, and how can I use the parts".

[@niklar55]

I've always done that, first from necessity, and now from habit!

[@DaveSmith-cp5kj]

@@niklar55 It's also good because then you don't have to keep buying chinese stuff that fails. You can buy the good stuff because you can extend the life beyond the intended use.

Thanks, but be sure that used hardened drills, or you need to reharden if you use basic drills, i use HSCO drills with hardened shank

[@stemer1149]

Very very good. So far I have used 6 or 4mm silver steel for small tool bit, hand filed. But it needs to be hardened and tempered. Your approach seems much better. Besides, using the lathe, one can set the angles precisely like you showed. Thank you very much!

[@TinC33]

Thanks, that hsco drills are just great for that.

[@lindsayfog5246]

broken carbide endmills are good for this sort of cutter too, they are the same material throughout, unlike some hss drills and some cheaper hss+cobalt bits. anyway its easy enough to check hardness and you'll find out pretty fast if it isn't.

[@stanfischer6175]

Enjoyed your video, I've done the same. I have a small Rockwell mill that will turn in excess of 6000 rpm's! I grind high speed blanks into thread tools. I use 1/4" shank grinding rocks from the local hardware store. While I wished I had a proper tool and cutter grinder machine I can make do. Watching your video makes me think of my little Rivett 608 lathe, it has indexing holes in the spindle plus collets to hold the work. Need to make a grinder holder like the one you made.

[@pricklyshark2337]

Хорошая идея!

[@martintobias6319]

Genius man👍

[@MrBLaauwen]

Great
But may i suggest making a guard for the grinding disks. One of those fly apart and it can hurt bad.

[@nikolaishriver7922]

Cool video. I would suggest offsetting your tool holder center hole so you can get more strength(more threads) out of the set screws. Also, it would be helpful for heavier turning to grind a flat spot on your tools for the set screws to sit against so they don’t rotate. Awesome work

[@TinC33]

I think to make flat surface for screw, but i see that it's unnecessary for so small insert, one screw hold it ok, but i got thread through the hole so i can fix it with two screw.
Biggest pros of flat surface is that alway hold on same angle position, because it set angle itself to a flat surface when tighten the screw.
