My guess is that the dremel just has too much slop for these bits. Any
suggestions.
The two Dremels I have tried have run-out enough to break a sturdy 1/8" bit!
Just NOT the machine for this application! A plain ol' "machinist's" 1/2"
chuck drill-press is more precise!

There are precision quill-motors, both high-freq. 3-phase and "air" which
will do the job (NSK comes to mind), but I guess $400 is more budget than a $90
Dremel (worth $12.95 on a good day!)...

Lotsa luck!
