I use a cheap Harbor Freight $39 drill press. It has lots of runout.
From Enco I purchased a microdrill chuck for $7.50 and 1/32 drill bits
by the dozen at $0.22 each. This combination makes a spinning drill
with lots of runout.
I design my boards so the center of each drill hole is etched. This
creates a starting point for a wobbly drill. The drill centers on
this hole and does its work cleanly. I replace the cheap bit when it
gets dull.
A head mounted magnifier, bought for $8, provides a closeup view of
the procedings.
For the occasional builder this is a nice system. You can spend lots
of money and time trying to get a "no-runout" system to use carbide
bits. I decided to just forget about them.
