Shrink fit chuck suitable to all inductive shrink fit units.
The Power Shrink Chuck is the shrink fit chuck for highest machining capacity in high-speed manufacturing. The optimized design combines high rigidity with dampening vibrations, therefore giving more protection to machines, spindles and tools.
  • Increased machining capacity due to higher spindle speed, higher feed and larger cutting depth
  • Shorter processing times
  • Quieter running, therefore better surface quality and protection of tools, spindles and machines
  • Higher machining accuracy
  • With threaded holes in order to balance with balancing screws
  • Cool Jet bores that can be sealed included
  • Safe-Lock pull out protection included
  • High rigidity
  • Slim at the tip
  • Dampen vibrations
  • High clamping force
  • Equally suited to high-speed manufacturing and heavy milling
  • Universal usage, saves space in tool magazine
Scope of Delivery
  • With backup screw
HAIMER TIP
For rpm higher than e.g. 8000 we recommend the optional cooling system Cool Flash. (on request)
