Shrinker Shrink Fit Tool Holders

Shrinker shrink fit chucks provide an optimal connection between the holder and the tool shank by utilizing the thermal expansion properties of the shrink fit tool holder. This clamping system is an economical solution that provides maximum clamping force and rigidity while dramatically increases tool life. In fact, you can count on 100% longer life from our shrink fit tool holders over conventional tooling.

For critical high speed or high precision cutting applications, Shrinker’s TIR (total indicator reading) and tremendous holding strength are benefit enough – most toolholders simply can’t achieve this degree of precision. And with our Maximum Velocity™ technology, all shrink fit tooling can be balanced to 2.5 G or better at 30,000 RPM.

Advantages of Shrink Fit Tooling:

  • Best possible TIR (total indicator reading)
  • Best possible balance
  • Best available gripping power
  • Increased tool and spindle life
  • Thin profile holders for machining hard-to-reach places
  • Short gauge lengths available for increased rigidity
  • Ability to preset for required tool length
  • Eliminates wrenches, collets, set screws and other accessories
  • Reduces costs associated with tool changes, holder maintenance and machine downtime
  • Design and build custom holders for any application
