Hydraulic Expansion Chucks represent the elite standard in tool holding, offering superior damping and high-torque clamping for precision aluminum and non-ferrous milling. Available in both HSK63F and ISO 30 interfaces, these holders utilize a sealed hydraulic system to ensure uniform clamping and a concentricity of ≤ 0.005 mm. Designed for rapid, tool-free changes using a simple Allen key, they significantly reduce vibration and extend tool life by up to 40%.

Features

  • Superior Clamping Precision: Delivers a guaranteed concentricity of ≤ 0.005 mm, ensuring maximum cutting accuracy and superior workpiece finishing.
  • Vibration Damping: The internal hydraulic oil chamber absorbs harmonics during high-speed routing, reducing tool wear and improving edge quality.
  • Extended Tool Life: High-stability clamping and reduced vibration can extend cutting tool lifespan by up to 40%.
  • High-Speed Performance: Precision balanced to G2.5 at 24,000 RPM for stable, high-speed milling operations.
  • Rapid Tool Changes: Allows for quick setup without external heating or pressing equipment; simply tighten the internal piston screw with the included T-key.
  • Extreme Durability: Engineered to maintain peak accuracy for up to 3,000 tool changes without loss of clamping force.
  • Versatile Sizing: Available in HSK63F and ISO 30 configurations; compatible with T521 reduction sleeves to accommodate multiple shank diameters.
  • Machine Compatibility:
    • HSK63F: Produced according to DIN 69893 for modern high-speed CNC centers.
    • ISO 30: Includes specialized retaining stud for HSD spindles.
  • Bi-Directional Use: Optimized for both right-hand and left-hand rotation with a 5.5 N/m tightening torque.
  • Made in Italy with high quality materials and workmanship.
