measure the shank of the bit. You should measure the flutes. The shank
is back tapered so that it will not "catch" on the hole you are drilling.
But even so, there are several factors which could still cause the
diameters to be different between individual bits, such as:
Different tolerance between cheap and quality bits
Allowable tolerance in manufacturing the bits because you are supposed to
use a reamer for accuracy. ;)
