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

[@philipbyrnes7501]

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

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.

Wow! What a brainy? Nice to watch this video. Here after i won't throwout broken D Bits.

[@georgewolf7063]

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. ;)

[@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.

[@nathaniellangston5130]

[@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.

[@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.

[@creast56]

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

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.

[@TinC33]

Thanks robert

[@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.

[@TomMakeHere]

What sort of hardness are you getting? Looks to work ok Have you tried grinding closer to the flutes as the shank is generally softer than the flutes Nice grinding work!

[@TinC33]

This drills are complete hardened from top to bottom made out of hsco

[@dalemcinnes1834]

@Chris Yes you can. Have you ever heard of annealing? Dale in Canada

[@DCFusor]

Now I'm glad I kept that big plastic drawer of "dull or broken" bits...I kinda figured a use for that super good steel would turn up. Milling bits too..

[@TinC33]

Good, just be sure to use hardened part, i forgot to tell bere that i use hsco drills wich is entire hardened also shaft. Mill bits will be right stuff.

[@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.

[@sunilmistri2714]

Very nice sir ..

[@MultiChaga]

You are brilliant, all my admiration...

[@richards6452]

Tine, very nice and precise way to make cutters. May I just comment that the end of a high speed drill is not completely hardened so that the drill chuck can "bite" into the shank and not slip. That being so the tool made from the far end of the shank will not be at optimum hardness to resist wear. A hardening and tempering cycle will address this and I note you have the equipment and set up to achieve this. The torch and the oil is all you require and a little research on the technique on UTube will show the methodology. Thank you for the excellent video, Richard
