💡 What controls torque and spindle runout in a high revolution air die grinder?

This handy setup relies on compressed air dynamics rather than electric motors to spin the cutter shaft smoothly.
* Airflow volume sets rotational stability and prevents wobble under heavy cut loads
* Inline regulators and grease pumps keep internal bearings spinning evenly without drift
* Rear exhaust tuning cuts backdrag noise and stops heat buildup inside the motor sleeve✝️
