Application

For high precision, centric clamping of milling, drilling and reaming tools – particularly for milling and heavy-duty machining during rough machining.

Execution

  • With axial longitudinal adjustment
  • Reducing sleeves for flexible application
  • Coolant pressure up to 80 bar

Advantage

  • Damping properties to increase the service life of tool and machine spindle
  • Very high torque transfer (dia. 20 = 400 Nm/dia. 32 = 730 Nm)
  • Vibration-damping effect reduces micro-cracks and improves the workpiece surface
  • All standard shanks can be clamped (dia. tolerance h6)

Notes

The previous standard DIN 69871 was superseded by ISO 12164.

Delivery
