It provides fast, secure clamping at speeds up to 25,000 RPM, enabling efficient high-speed milling, drilling, and finishing tasks. The hydraulic expansion mechanism grips cutting tools evenly and securely, delivering stability and reduced vibration for better surface finish, dimensional accuracy, and extended tool life.
- DIN69871 compatibility: Seamless integration with a broad range of machining centers and tool holders, reducing setup time and downtime so you can move quickly between jobs.
