Is anyone running an air tool? Thought of this while considering a replacement for my second Disposable Freight Co. cutter in 3 weeks. I see plenty of sub-100USD pneumatic grinder/drill options advertised with 20k+ RPM. Obviously this would require a good compressor/large tank/shop air setup.
You could control speed with a cheap solenoid-based air pressure regulator, turning it off entirely during non-cutting moves.
Coefficient with an existing needle chip blasting/cooling setup? These tools are also tiny and lightweight compared to our electric routers.
Is this a crazy idea? Not enough torque?
