I have drilled .018" holes (.457 mm) with the Westwind, and I'm sure it can do smaller. I have drilled a whole board without breaking a single bit. I have it rigged up so I can put it on my Bridgeport in a couple minutes. See http://pico-systems.com/wwspndl.html for a few pics. I actually got the motor for free, I got a bunch of stuff off an Excellon tape-NC PCB drilling machine. This thing had an air bearing X-Y slider table on a 5' x 5' x 8" thick granite surface plate that was supposed to weigh 17000 Lbs! I got the X-Y drives with insanely accurate ballscrews, the two spindle motors and a bunch of other stuff for $300 many years ago. The X-Y drives and ballscrews are on my Bridgeport.
