Application
For high-precision and centric clamping of milling, drilling and reaming tools – particularly with milling and heavy-duty machining during rough machining.
Execution
- With axial longitudinal adjustment
- Reducing sleeves for flexible application
- Very high concentricity (< 3 µm)
- Coolant pressure up to 80 bar
- Temperature-resistant up to 100 °C
Advantage
- Robust version ideal for HPC+HSC machining
- Damping properties to increase service life of tool and machine spindle
- Vibration-damping effect reduces micro-cracks and improves the workpiece surface
- All standard shanks can be clamped (dia. tolerance h6)
- Very high torque transfer (dia. 20 = 650 Nm/dia. 32 = 890 Nm)
Notes
The previous standard DIN 69871-1 was replaced by ISO 7388-1.
Delivery
