Heavy Duty Shrink Chuck with Safe-Lock™
similar JIS B 6339 · BT50 with face contact

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
High runout accuracy: 3 μm
Reinforced outer contour
With dirt groove in the clamping bore
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
Safe-Lock™ pull out protection included

To shrink with all HAIMER Power Clamp 20 kW shrink fit units and shrink fit machines with 13 kW HD-Coil.

Technical data subjects to change without prior notice.

The most important features:

Safe-Lock™ pull out protection

Highly accurate clamping due to shrink fit technology
High torque due to form closed clamping
No loss of accuracy
No pull out and no spinning ot the tool
Groove on tool shank is directed so that the tool will be pulled into the chuck (depending on direction of rotation)
