Aluminium Profile Type Router - Initial questions

[Neale]

I also couldn't find an obvious answer on this - can I use normal 1/2" router bits in the spindle or does everyone use endmills? Obviously something like a Lock Mitre bit would be a bad idea, but the simple 2 flute straight bits, chamfer etc..

One way to look at this is, "Would I use this cutter in a handheld 1/2" router at 26000RPM?" Or even a 1/4" router. If the answer is yes, then go ahead with it in a more powerful spindle with much better control!
