Cat. & BT Shank Balanced Precision Chuck
(Alternate to Hydraulic Chucks)







Increase Productivity At An Economy Price With This Unique Precision Chuck.

This high precision chuck is designed specifically to meet the demands of today’s new generation of machines and cutting tools. It’s powerful clamping force and ability to hold tools within 50 millionths T.I.R. eliminate the need for expensive hydraulic chucks and conventional milling chucks.
  • Clamping surfaces ground directly from the tool holder body. Holding a cutting tool within 0.0002" T.I.R. is achieved with no adjustments.
  • Is ideal for rough milling and finish milling. Because of its unusually high accuracy, it is perfectly suited for hole making applications that normally require hydraulic chuck or boring operations.
  • Ensures greater work piece accuracy, while delivering increased feed rates and tool life.
  • Patented, vibration-damping structure. This chuck interrupts the transmission of helical vibrations to allow increased RPM and feed rates.
  • Guaranteed high accuracies. Tools clamp within 0.0002" T.I.R. with no adjustment. Truing screws that contact directly to the tool shank can be set easily and quickly to achieve T.I.R. within 50 millionths.
  • Ideal for today's finest machine tools. These chucks are balanced to 22,000 RPM and are sealed for coolant-through applications.
  • Locking screw. In addition to exerting extremely powerful clamping forces, this high precision chuck is equipped with a Weldon type screw to eliminate tool pullout common with standard heavy duty milling chucks.
  • Value pricing. These high precision chucks can replace expensive hydraulic chucks and heavy duty milling chucks, yet are available at a fraction of the cost.
The bottom line: Increased productivity.
