Royal 5C Emergency Step & Expanding Collets
Easily Machined To Required Size
- Unlike chucks and most collets that grip the OD of a workpiece, 5C expanding collets are designed to grip on the ID of a part.
- Accu-length design ensures precise workpiece positioning – no z-axis movement.
- Collet head is easily machined to required size. Can be re-machined as necessary.
- Concentricities of ±0.0002″ can typically be achieved using Royal 5C expanding collets.
- Made from 1144 steel that can be hardened after machining for wear resistance.

*We recommend ordering a collet with a head diameter at least 1⁄2″ larger than workpiece diameter.
Note — these step collets close on the 10° angle, not the head OD. When using, be sure part is sufficiently clamped.
