Torque Wrenches for CNC Retention Knobs
 |  |  |
Prevent damage to CNC spindles and tool holders when installing knobs. These wrenches torque retention knobs to manufacturer specs to avoid overtightening that can bend or misalign your setup. Set your torque and the wrench signals when it’s reached with an audible click and an impulse in the grip. All come with a calibration certificate, which includes test measurements that confirm accuracy.
