What would be the best approach when using carbide bits with a hand
drill motor? One other thing: Ever used a diamond-coated bit? A
long, long time ago when I was a Navy jet mech, we had to drill out
some super-hard fasteners on an N1 case. If memory serves, someone
went to dental and got some "diamond dental bits". Whatever they
were, they worked pretty well.

Carbide in a hand drill tends to get you a lot of busted drill bits.
They dont take sideways bending, something very hard not to do when
runnng a hand drill.

I can, after years of practice, not bust 1/8 and up, if Im very very
careful. But I generally stick carbide in a drill press.
