What CFM compressor is required? most DIY "Router guys" wont have the luxury of a 200ltr receiver and 18CFM hydrovane units....Not to mention sympathetic neighbours :naughty: :idea:

My hydrovane is only 10 CFM

Mind you I do have two of them

What about these for PCB drilling / routing?

Some have integrated electronics, and some are high speed and are continuously rated.
We also have torque curves.

All good stuff but it is speed I am looking at. A Dremel tops out at 33,000 rpm, no load, and I consider that a little pedestrian.
Ok so gear things up but using something like belt drives at high rpm involves tensioners and even then at high speeds perceived internet wisdom seems to think that belts stretch, slip, burn out, skip out of grooves, become unbalanced, 'become complicated'. Gears seem to suffer a similar perceived status of 'complicated'. At the moment my thinking is that direct drive is the way to go but I am still very much open to persuasion and/or reasoned argument

What speed and torque are you after?
the fastest we offer has a no load speed of 43000 rpm.
I have seen small motors run faster, but they were induction motors specially made for drilling applications like dental drills, but they can be expensive.
These were made by http://www.airbearings.co.uk and they can offer speeds of up to 300000 RPM.
but at these speeds expect to pay a lot and will also use air bearings
