SK20-60-90 BT Collet Chuck Adapter CNC Holders Cutting Tools Milling Arbors

Features:

1. Standard roate speed is 40000RPM G2.5
2. SK collet taper is 4 degree , to increase the power of clamping
3. All round ball nut could be able to reduce the resistance and noise
4. Improve the stability and accuracy
5. Collect must be assembled into the clamping nut before inserting into the chuck.

Specifications:

It reduce the clocking resistanced and also show best performance on heavy cutting.
