Quick-Grip™ Emergency Collets

QG-65 Emergency Collet shown
  • Semi-hard Quick-Grip™ emergency collets are designed to be machined in-place by the user to accommodate special sizes, shapes, steps, etc.
  • Available in assorted pilot hole sizes to minimize machining time.
  • Collets can be counter-bored beyond standard capacity, eliminating the need for a three-jaw chuck on many jobs. The chart below provides some basic counter-bore guidelines, but many other diameter/depth combinations are possible. Please contact Royal for additional information.
  • Boring fixture holds collet segments firmly in-place and puts collet under slight compression to ensure accuracy and roundness during machining. Order fixture separately.

Royal Quick-Grip™ Collet Counter-Bore Guidelines

Boring fixture holds collet segments firmly in-place and puts collet under slight compression to ensure accuracy and roundness during machining.

  • The parameters shown represent a sampling of counter-bore possibilities. Other diameter/depth combinations are possible. Please contact Royal with your specific requirements.
  • For precise z-axis positioning, best practice is to use a Royal stop.
  • Users can counter-bore their own emergency collets, or order to size as hardened and ground specials.
  • For a better understanding of counter-bore collets and their use, please contact us.
