Hydraulic Chucks

Optimum Performance for round-tool applications.

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.

Reducer sleeve anatomy

Reducer Sleeves

  • One-piece design with slot configuration to seal coolant.
  • Capable of up to 120 bar (1,500 psi) coolant pressure.
  • Cutting tool shank requirement tolerance is h6 and Ra ≥0,3 μm (12 μ in) surface finish.
  • Maximum collapse is h6.


Hydraulic Chuck Extensions

Hydraulic Chuck extensions are the perfect solution for tight workpiece situations and long-reach applications. For use in all drilling and reaming applications. They offer modular flexibility for lathe and multi-axis machine tool applications.

  • Fits in all hydraulic chucks.
  • Excellent runout ≤ 3 µm.
  • Through coolant capability.
  • One clamping screw ensures easy handling.
  • High flexibility in conjunction
          with reducer sleeves.
  • Increases tool life by adding a
          dampening effect.
  • Axial tool length adjustment of 10mm.
  • Fine balanced G2.5 at 25,000 RPM.
