The cnconabudget spindle with a small DC brush motor is an entirely different animal than a 1.5 kw brushless spindle with an inverter. Other than the fact that they both rotate and hold bits they don't have much else in common. With very small bits you need very high speeds. If you just want to go fast, Harbor Freight was selling a 60K rpm air powered tool for a while. It looks like a big dentist drill and it holds 1/8th bits. I bought one for about $20 on sale and ran it briefly but never as a spindle - yet. I have no idea how much real power it can deliver. Probably less than 100 watts.
