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
- Heat-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)
Notes
The previous standard JIS B 6339 MAS BT was superseded by ISO 7388-2.
Delivery
1x short, heavy-duty BT40 hydraulic expansion chuck (ISO 7388-2)
