For any application, providing an unparalleled combination of accuracy and clamping force.

High Performance

Universal solution for drilling and tapping.

Slim Line

For long-reach applications and narrow conditions.

Activation of the chuck is achieved by turning the piston screw, which pressurizes the hydraulic fluid and exerts force on a thin-walled membrane along the length of the clamping bore.

This highly concentric clamping force not only holds the tool shank more securely, but also produces a dampening effect that reduces vibration and helps eliminate micro-cracking on cutting edges.

All part of the First Choice Program. 

Easy to select, easy to order, easy to apply, exceptional performance. Learn more about First Choice.
