Specs At A Glance

Good To Know

Q: How often should CNC retention knobs be replaced? A: It is recommended to inspect retention knobs regularly and replace them after 2,000 to 3,000 hours of spindle time to prevent catastrophic failure.

Q: Can these be used on BT40 spindles? A: No, these are designed specifically for CAT40 spindles and will not fit BT40 configurations due to different thread and flange standards.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
