BTW, have you seen the small DC powered clone at Harbor Freight? It
runs on 12 VDC, and comes with an AC adapter. I was thinking about
using one (or more, with different sized drills) with a homebrew CNC
machine to drill PC boards.

I have one of those HF pseudo-dremels. Not very torque-y at all. Bogs
down very easily. A very light touch is required.


Plus the collets are brass and wear out in no time. Good for a one or
two time use project, no substitute for a pneumatic die grinder.
Bearings suck on them, too. Whadda ya want for $6 anyway? Spend a
couple of bucks more and get the mini-pneumatic die grinder. Some of
the ones I have accept Foredom collets, too.


Well you need an air compressor for one of those, a tool relatively few
people own. I use a pneumatic die grinder occasionally, but it's louder than
my Dremel and it spews out a bit of oil in use.


Sounds like you nead an oil trap next to your bench.

Good Luck!
