💡 What causes a loose collet nut on a manual mill during heavy cuts?
Proper installation prevents vibration and keeps cutting tools centered on rough stock.
- Worn spindle threads and improper torque sequencing let shanks slip under load
- Handy preload alignment matches factory tolerances for zero chatter
- Consistent grip reduces tool deflection and extends carbide life
