I want a high speed milling option for my CNC X3 (but the question is generic to any CNC mill).
The intended purpose is for cutting wood on the mill, as well as using small cutters on Aluminum.
Here's a pic I pulled off of Bob Warfield's site that shows what I have in mind.

I'm stuck deciding for either the Bosch Colt PR20EVSK or the Makita RT0701C, both of which get great reviews on the wood working boards.
Makita
1.25 HP
10,000 - 30,000 rpm
1/4" & 3/8" OEM collets available
no after market support (would have to use a collet reducer to run small cutters)
Bosch
1.0 HP
16,000 - 35,000 rpm
1/4" max size collet (which I think is adequate)
1/8" after market collets and high precision after market collets available.
So my questions are....
Would I be better with the extra rpm at the low end or the high end?
Would using a collet reducer on the Makita give me too much run out?
I've inspected both and they are each really nice units and the price is the same. Both have soft start and speed control to put more amps to motor under load.
