What PCB drills are you guys using? Anyone got any  recommendations?



Totally home-brew with "instrument grade" 400 Hz. 3-Ø  quill-motor rebuilt 
with 1/8" collet-chuck.  Turns 12,000 RPM, fixed.   Would prefer twice that, but 
motor was "surplus" cheap, but very  fine.   New, probably $200?
 
This is mounted in a fixture with Thomson linear  ball-bearings.  Only 1/4" 
"Z movement", but drills a hole per second with  ease.  LOTSA "DIY 
work"!!!!!!!!!!!!
