Some suggestions for sources:
The Electronic Goldmine
http://www.goldmine-elec-products.com/searchprods.asp
part no. G961
is three carbide router bits with 1/8 " shanks for $2. I've bought
these in the past and they have very good finishes and the shanks are
about 1/2 inch long.
If you're in good graces with your dentist, ask him for used dental
drills (actually minature router bits.) However be aware that these may
only be carbide brazed to HS steel shanks (like the ones I got.) But I
guess that some may be carbide all the way. I'd be interested if your
results vary!
Look at part no. 8788A124
from McMaster Carr 1 1/2 in. long by 1/8 in dia. carbide drill blanks.
$1.95 ea. Many other lengths and dia. available.
