Power Shrink Chuck with Safe-Lock™
similar JIS B 6339-2 · BT40 with face contact
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.
- Additional support on the flange surface for more rigidity
- Increased machining capacity due to higher spindle speed, higher feed and larger cutting depth
- Shorter processing times
- Higher machining accuracy
- Quieter running, therefore better surface quality and protection of tools, sindles and machines
- With threaded holes in order to balance with balancing screws
- Cool Jet bores that can be sealed included
- Optional: 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

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)
