- Slim shrink-fit chuck-style design makes it suitable for narrow interference contours
- Excellent damping properties
- Max. concentricity < 0.003 mm
- Standard tool changes as with expansion chucks without requiring additional devices
- Reducer bushings enable various applications
- Pre-balanced to G2.5/25,000 rpm
