💡 How does a dedicated carbide rotor file tool keep cutting force stable when dragging across flaky paint layers?
Grasping the right air pressure ratio keeps the bit spinning hot enough to shear debris without bogging down.
- Consistent rotational momentum shatters hardened oxide flakes rather than pushing them aside
- Reduced torque drop off lets you apply extra hand weight without killing the motor speed
- Quick-change collets swap out dull cartridges in seconds to maintain peak abrasive contact
