WIDIA™ Shrink Fit Technology How it works...

Heat shrinking is not new technology in the tooling industry, but only recentlyWhen the toolholder is heated, the bore expands and the shank is able
has it been applied to quick-change toolholding systems. Shrink fitting worksto slip inside the bore. As the toolholder cools, it shrinks, clamping the
by having toolholders with an internal bore that is slightly smaller than thetwo pieces together. This creates evenly distributed pressure with minimal
connecting end of a cutting shank.vibration between the toolholder and shank that resembles a monoblock tool.

Advantages of Shrink Fit Tooling:

  • Evenly distributed pressure 360° along the length of the cutting tool.
  • Slim and short toolholder designs can be achieved due to the lack of moveable parts.
  • Absolute symmetry of the grip provides the best possible balance for high-speed operations.
  • Stronger clamping force than collet or hydraulic chucks.
  • Can be repeated thousands of times.
  • Capable of greater speeds and feeds.
  • Adapts to various shank types.
  • Increased productivity.
