COVID-19 : La réponse de Kennametal


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.




Highest clamping force in the industry.

Diameter 20 and 32mm: Runout of 3 μm or less at 2.5x diameter overhang [6 μm for diameter 50mm].

Balanced G2.5 at 25.000 RPM, delivering precision.

3 clamping bore sizes for all applications. 20, 32, and 50mm.

Short projection length and 40% thicker front wall enabling high cutting parameters and optimum surface quality.

3x higher clamping force than High-Performance line.
