Patrick WallinHow to make a lathe cutter
https://www.youtube.com/watch?v=2R0l6I1yrrkIt's kind of boring but if you use a lathe it's an OK video.

William D. WhitePatrick,
Well, the presentation is quite a bit longer than it needs to be. Besides that, any information on forming and dressing cutting tools is some of my favorite subject matter!
I will submit that using a 1200 grit diamond wheel with a synthetic oil or water based coolant is preferable to dry grinding; you'll get a beautiful razor sharp finish with both high speed steel and carbide, and a 1x6" wheel is not that expensive either:
HERE. You'll also need a good coolant:
Gem Lube works perfectly with these wheels...for grinding anything!
I firmly believe that the key to precise micro-machining is the ability to impart a micro-edge to your micro tools!

Patrick WallinWilliam,
I agree. All the way through the video I wondered if he was going
to change stones at the end.....

William D. WhiteMike,
These carbide micro drills are still available through
Harbor Freight Tools. They come as random selections and the smallest ones usually have a little shoulder which can be profiled as the one I made. The 1/8" blanks Mr. Kaszubski has work great and can also be held in a standard pin vice.

David E. Booth, Jr.Here is here I buy drill bits. They are good to deal with, and do not have a minimum order requirement. They carry bits in a full range of English and metric sizes and materials, including carbide, titanium, and HSS.
