So I figure a ten thousandth is within margin of error.

You would be surprised what just .0001" of tolerance will effect. I have heard people having that much LESS main bearing clearance and causing a catastrophic failure. I know this isn't an engine, so please forgive me.
On to the drill bit. Could you have a deformation on the end of that drill bit? Are you measuring the very TIP of the drill bill or a little further up?
Mudsport96:
No not the very tip, just behind the tip of it. Was thinking the end might be cut different or may be bevelled for cutting. They are Bowman gold oxide drill bits. 135 degree split point...
I'm just going to cross my fingers and hope for the best. I think it will be ok
