Power Shrink Chuck
DIN 69893-1 · HSK-A63

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
  • Higher machining accuracy
  • With threaded holes in order to balance with balancing screws
  • Cool Jet bores that can be sealed included
  • Cooling with Cool Flash for an extra charge

The long versions (A = 130 and 160 mm) with slim tips are especially versatile to use.

  • 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
