Re: 0.502" Drill bit?

I second...or third...or n... the idea of using a reamer...
Proper fit in a hole is made by using a reamer. You can start the hole with a drill... or bore it out...but the final thousands are taken with the reamer.

Reamers for .5, .375, and .25 should be part of any team's toolkit..
(rather .501/.502...etc) to use with 1/2", 3/8", 1/4" shafts.

If you are looking for press fits... you may have to purchase different reamers that will make the necessary pressfits for your bearings or whatever else you want to press in...
