Again, I should have been more clear in what I'm writing... sorry. Spindle reaches max torque at 12kRPM, but it can spin up to 24kRPM:

It works well with both alu and wood. With constant TEA paths and smaller TiAlN coated endmills it has enough torque for light work in steel (min. 6kRPM), but I don't do that often since the machine is not rigid enough.
