These toolholders are designed for ISO20 ATC Spindles. The balancing of these toolholders is done to a very high grade, and that’s why they can run up to 30,000RPM.
We strongly recommend when working at high RPM you always verify the toolholder has 100% fit and the pull stud is 100% compatible with your spindle. Incorrect fit can cause major bearing damage and destroy the ATC Spindle
