Description
Version:
- High-temperature steel.
- Integrated length adjustment of the tools.
- For HSS and solid carbide tools.
- Shanks hard turned (smooth cutting action!).
- With RFID/Balluffchip bore.
- With coolant channel bores and threads that can be sealed.
- With tapped holes on each side for balancing screws.
- Reinforced version/contour.
- Polished surface.
- Specially mounted carbide core in the shrink-fit chuck body.
Advantage:
- Vibration-damping.
- Better workpiece surface finish.
- Optimised tool life.
- Increased process reliability.
- Lower corrosion tendency due to polished surface.
Application:
For clamping tools with plain shank (h6 shank tolerance). Suitable for inductive, contact and hot air shrink-fitting units.
