Re: [DMCForum] Re: Glitch #182



titanium bits, imo, suck.  "high speed" bits suck.  Black 'hardened' bits
suck.  They may be good for wood, but I have rounded off too many bits in
hard metal applications.  You need COBALT bits.  I haven't managed to
destroy one yet, even drilling though various types of stainless.  The
ones I have have a 4-point edge, so they look a little different from the
top.  Though, I haven't seen any cobalt bits without a 4-point edge. 
I've found that the cobalt bits work best with high pressure/low RPMs. 
You can most likely pick some up at your local true value/ace hardware
store.

There's always tungsten carbide if you're rich and desperate.  I mean
have lots of $$$$!
