Description
Version:
Shrink-fit chuck for very high metal removal rates during high-performance cutting (HPC). The optimised design combines excellent stiffness with vibration damping. This protects the machine, spindle and tool.
- Safe-Lock tool pull-out protection prevents the tool being pulled out accidentally.
- Higher metal removal rate due to higher speeds, higher feed rates and greater cutting depth.
- Shorter machining times.
- Runs more smoothly, which improves the surface quality and protects the tool, spindle and machine.
- With tapped holes for balancing with screws.
- With pluggable Cool Jet holes.
- With length adjustment screw (adjustment path 10 mm).
Application:
For clamping tools with parallel shank to h6 tolerance with Safe-Lock ground surface. Suitable for all types of shrink-fit unit such as inductive, contact and hot air shrink-fit units.
Optional extras:
For milling cutters with Safe-Lock clamping flat, see solid carbide milling cutters.
