Drilling with a twist drill in a drill press is not a suitable way to
get
_perfectly_ on-center holes in anything.

Indeed there is no such tool that exists...

then re-index (or re-check
your index of) the workpiece,

Why do you recheck after drilling? If an axis of the mill is not moving
while you are cutting, it must be clamped - always.

Yes. Just 'checking' never hurts a precision job.


and "drill" the hole with a fly cutter,

Perhaps you mean, "boring head"?

Ummmm.... Blush... yep...


bits drill more than two thousanths over their miked-out size, they need
regrinding to center the cut.

This depends on the diameter of the drill, of course...
