Application
Simple, radially adjustable tool holder, ensures the precise friction required. Concentricity and alignment errors can be compensated without vibration, high cutting and service life is consequently ensured. The integrated coolant supply ensures an optimal supply of cooling lubricant to the reamer's cutting edges.

Execution
  • Simple and precise adjustment via adjusting screw
  • The thread and the wedge angle on the adjustment wedge create a self-locking effect, so there is no setting behaviour
  • Radially adjustable to 0.015 mm for permanent concentricity "0"
  • Excellent damping properties to increase the service life of tools and machine spindles
  • With 10 mm axial length adjustment
  • avec réglage de la longueur axiale de 10 mm
  • goujons d'extraction requis, n° 23690

Advantage
  • Concentricity easily adjustable to 0 μm
  • Reducing sleeves for maximum flexibility
  • Optimum precision and surface quality
  • Longer cutting tool service life
  • High-precision centric clamping

Delivery
1x HSK63 hydraulic expansion chuck (ISO 12164)
