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
- Radial and axial coolant transfer = AD/AF
- Radially adjustable to 0.010 mm
- Excellent damping properties to increase the service life of tools and machine spindles
- With 10 mm axial length adjustment
- Pull studs no. 23690 required
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
Notes
