Reply to "TiN drill bits"

bob2:

Thanks for the tip. That's a new one on me - I have occasionally had problems with drill bits grabbing in brass, but this is the first time I ever heard of a zero rake bit. I did some Googling and the only commercially made zero rake bits I could find were for Plexiglas and acrylic - they have 90 degree points and are not suited for metal. I did, however, find a nice how-to for modifying your own. Next time I have to drill brass I guess I'll have to get out a honing stone.
