Application
For high precision centric clamping of drilling, reaming and milling tools.
Execution
- Concentricity tolerance < 0.003 mm.
- With axial longitudinal adjustment.
- Reducing sleeves for flexible application.
- Coolant pressure up to 80 bar.
- Heat-resistant up to 50°C.
Advantage
- Vibration-damping effect reduces micro-cracks and improves the workpiece surface.
- Damping properties increase the service life of the tool and machine spindle.
- High torque transfer (dia. 20 = 400 Nm/dia. 32 = 730 Nm).
- All standard shanks can be clamped (dia. tolerance h6).
Notes
The previous standard JIS B 6339 MAS BT was superseded by ISO 7388-2.
