I am parting out a PCB drilling CNC machine. Inside of it, there is
a
good pile of a few lbs of carbide "PCB Drills". These are tiny
drills
and perhaps end mills, with what looks like 1/8" shanks.

I wonder if there is any non-PCB use for them. I do realize that
these
carbide drills can only be used in CNC equipment, and I have a CNC
milling machine. Trying to think of any good use cases but can't.

They work reasonably well on a milling machine with this type of
manual-feed adapter:

I have a small sensitive chuck like that. I am sure that I would
sell
those drills, but I wanted to keep at least a couple dozen of them,
and I am not sure which ones to pick.

You could try them to find the smallest size that doesn't break on
your drill press.
