Royal QG-80 Emergency Collets

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 us 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.
