Pullback design with an internally threaded back plate enables the use of a stop rod.
Fixture face is precision ground and includes tapped holes, enabling the use of custom stops, locators, etc.
Bottom and all four sides are ground for both vertical and horizontal mounting.

Industry-leading 0.062" Gripping Range (0.080" for QG-100) – greater than other quick-change collets on the market and more than 12X that of traditional spring collets.
Royal Quick-Grip Collets are precision-ground to nominal size, with a gripping range of ±0.031" (0.040” for QG-100) to handle undersized/oversized stock.
Example – a ½" QG-65 collet is ground to 0.500" dia., and can hold any part ranging in size from 0.469" – 0.531" dia.
Ultra-Precision Accuracy – 0.0002" TIR or better guaranteed on round-bores. Total system accuracy (chuck + collet) guaranteed to 0.0004" or better.
All Royal Quick-Grip™ Collets are designed for minimal projection beyond the chuck face (≤ 0.020") for optimum rigidity and machine work-zone utilization.
All models have a smooth gripping surface, but round-bores are also available from stock in a double-serrated version for very aggressive first-op machining.

Vulcanized rubber between the hardened steel collet segments provides outstanding protection against coolant and chip penetration, and Royal’s advanced vulcanization process carries a lifetime guarantee against failure.
Collets can be counter-bored for increased capacity.
S-type master collets available for QG-65 and QG-80 chuck models.
Royal Quick-Grip™ Collets are compatible with some other brands of quick-change chucks, but note that the QG-80 and QG-100 models have a six-slot design (for increased gripping torque) that requires the use of a Royal installation tool. Call us to verify compatibility.
Custom sizes and shapes available as quick-ship specials. Collet segments can also be carbide-coated for extremely harsh applications. Contact one of our applications engineers at 1-800-645-4174 to discuss your requirements.
