118 Vs 135 Drill Bits

[Bob Korves]

Just looked up Drill Dr., smallest it will sharpen is 3/32, .094. I need to be able to sharpen .037, about one third diameter of 3/32. Guess I'll just have to continue doing them by hand.

I am lucky to see the cutting edges on drills that small, much less grind them accurately. I have a bunch of tiny drills, but very rarely use one, have to hold my tongue just right or it is broken before it is tight in the chuck... 8^) I do not grind drills smaller than 3/32", just buy new ones.

Look at this well made and cleverly designed drill grinding machine:

that thing is huge considering it maxes out at 3/4" bits.
