I picked up this drill from Amazon a while ago, and it is the best small tool for model making that I own! It is small (6" long), operates at low rpm, and is able to accommodate drill sizes from #80 (.0135") to #22 (5/32"). This is perfect for drilling treenail holes. Just use an awl to put a tiny hole in the wood, rest the drill bit in the hole and turn the drill on. Excellent control, unlike a Dremel, and no more sore hands from using a pin vice, or broken bits using the manual push-action hand drill.
I cannot recommend this more highly! And only $30!
