the standard drill diameter for PCB work is 1/8" dia. Therefore, to
answer your quesiton, 1/8"

You can buy drill bits on E-bay for about 50 cents each, in lots of
25. Go for the guys who will tell you up-front what diameter drills
you will get.

I bougth a cheap set and 45 pieces were 13 thou or less. Totally
unusable for my needs.
