That's the one. :) I bought one, cut a hole in the wall for the novelty of 
it, and then promptly tossed it under the workbench. It looks usable as a 
spindle for a micro-mini-mill-drill. 30k RPM, pretty solid 1/8" collet, huge 
cooling fan. The housing is FRP, pretty flexible, so a really rigid mount 
will be wasted. A split clamp around the throat and a single 4mm screw in 
the handle mount lug, 5" distant, should suffice for light drilling. (A few 
small steppers and a Taiwanese XY table will make a usable CNC drill. I'll 
see about a Kavo and ER-16 collet after/if this toy burns out.)

BTW, I use their down-cut spiral bits in the laminate trimmer and router for 
rough cutting MDF and plywood. They're cheap and last long enough that I 
forget how much I paid for the last 10 pack. Ironic, isn't it? It saves the 
good carbide for real work.
