Shrink Fit Chuck Heavy Duty Chuck, ASME B5.50 · CAT50
Quality pass
Chuck body fine balanced G2.5 at 25.000 rpm or U < 1 gmm
All functional surfaces fine machined
Taper tolerance AT3
Coolant supply form AD/AF
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. Heavy Duty Chuck is the shrink fit chuck for extreme cases. The contour is optimized for highest rigidity and clamping force.

  • Smooth clamping of the tool shank
  • No deformation at the tool shank after shrink process
  • TIR less than 0.00012" (3 µm)
  • Reinforced outer contour
  • To shrink with 13 kW HD coil or with high performance shrink fit unit HAIMER Power Clamp Profi Plus (20 kW)
  • With internal groove in the clamping bore
  • Cool Jet coolant bores that can be sealed included
  • With threaded holes in order to balance with balancing screws
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
  • Extended tool life up to 100%
  • Higher reliability of cutting process
  • No more balls of chips on tool
  • Cool Jet starting from shank diameter 6 mm
Cool Flash (optional)
  • Optimized coolant bores with coolant outlet through slots
  • Coolant directly to the cutting edge
  • Extended tool life up to 100%
  • No more balls of chips on tool
  • Optimized runout accuracy! No additional unbalance! No disturbing clearance!
  • Cool Flash available for shank diameter 6 - 25 mm
