Shrink fit toolholders provide concentric clamping force of 10,000 lbs or more directly on the tool shank.  This translates to TIR as low as 0.0" to 0.0002".  Ideal for high speed or high torque machining applications.

Shrink fit toolholders are balanced to 18,000 RPM at G2.5 for high speed performance.  Balancing to higher speed is available as well.

With shrink-fit tooling machinists report an increase in tool life up to 50%, and are able to increase feed rate 25%.
