Machine Shop Solutions

Problem: Low quality milling chucks cause vibration and runout during machining that can lead to inadequate finishing results. Solution: A powerful roller bearing design increases grip and reduces vibration, giving you low runout accuracy and improved surface finishes.

More Clamping Torque, Less Vibration & Runout

The CAT 40 Hi-Power milling chuck is aptly named for its ability to increase clamping torque by up to 400%, leading to higher productivity and longer tool life compared to traditional holder options. The Hi-Power uses a specially-designed roller bearing to offer low runout accuracy and higher friction resistance, increasing both clamping strength and finishing results in one go. Your entire holder is protected by an anti-corrosive coating, while a sealed bearing mechanism shields the clamping nut from dust and coolant interference for added longevity.


  • Very high clamping forces lead to increased productivity and tool life.
  • Immediate improvement in surface finish due to less vibration.


  • Low run-out accuracy of 5µ @ 3 times the tool diameter.
  • Sealed bearing mechanism of the clamping nut keeps out dust and coolant.
  • Roller bearing design provides high friction resistance and greater gripping torque.
  • Protective anti-corrosive coating on entire tool holder.
  • Up to 400% increase in clamping torque compared to traditional collet holders.
  • Higher clamping force ensures a stronger, more rigid tool which in turn delivers improved tool life and better surface finishes.
