I have to drill a number of flat bottom holes, 7/8" diameter and 1/10"
(.1") deep in some 2/10" (.2") thick aluminum. Is there a source for
flat bottom drill bits of this size that will fit in the 1/2" drill
chuck that's on my drill press? If there are no bits of this size with
a turned down 1/2" shank, can an adapter be purchased to go from the
7/8" bit to the 1/2" chuck? Thanks for any help. Marty

In a drill press? You're dreaming. You *could* make it happen, but the
hassle to do it would be ridiculous. Mill.

Bottom cutting plunge endmill, followed up by the correct drill bit
for the screw shank hole. Or a ready made counter sink for the screw.
Aint no other way to do it without it walking all over hell and gone.
