Chucks HYDRAULIC CHUCKS HYDROFORCE™ For any application, providing an unparalleled combination of accuracy and clamping force. Optimum performance for round-tool applications. 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. The highly concentric clamping force secures the tool shank, while the pressurized fluid delivers a damping effect that reduces vibration and helps prevent Explore Collets micro-cracking on cutting edges. and Sleeves Explore HSK E5 kennametal.com
