• 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 to verify compatibility.
