Heavy Duty Shrink Chuck, DIN 69893-1, HSK-A125
Quality pass
Chuck body fine balanced G2.5 at 25.000 rpm or U < 1 gmm
All functional surfaces fine machined
More accurate than DIN
Cool Jet, can be sealed
Shrink fit chuck suitable to all high performance inductive shrink fit units.

For heavy machining applications it is now possible to replace the Weldon tool holders finally. The Heavy Duty Chuck is the shrink fit chuck for extreme cases. The contour is optimized for highest rigidity and clamping force.
  • No deformation at the tool shank after shrink process
  • High runout accuracy: 3 μm
  • Reinforced outer contour
  • With internal groove in the clamping bore
  • With threaded holes in order to balance with balancing screws
  • With Cool Jet bores that can be sealed (Thread M4) and 6 bores
  • Higher coolant flow rate due to optimized coolant bores
  • To shrink with all HAIMER Power Clamp 20 kW shrink fit units and shrink fit machines with 13 kW HD-Coil
Scope of Delivery
  • With backup screw
HAIMER TIP
For RPM higher 8000 U/min we recommend the optional cooling system Cool Flash. (on request)
The most important features:
  • 1. High runout accuracy (< 0.003 mm)
  • 2. Reinforced wall thickness at the clamping range
  • 3. Extremly rigid outer geometry
  • 4. Dirt groove in the clamping bore for safe clamping force
  • 5. Expansion grooves in the clamping bore
  • 6. Standard with Cool Jet (can be re-sealed)
  • 7. Safe-Lock (optional)
Cool Jet (optional)
  • Optimized coolant bores, aimed at center
  • Coolant directly to the cutting edge
