Although we frequently use a dental style micro-drill
with carbide ball mills for cutting circuits, we
prefer milling vs. drilling.  We have many precision
drill systems made by Servo Products.  We fit them
with carbide end mills.  These units give us a flat
bottom milled cut with great depth control.  You can
see a pictures at:
