Expanding collets

Royal 5C Internal Expanding Collets grip on the inside diameter of a workpiece, enabling the complete OD to be turned. The accu-length design ensures precise workpiece positioning - no z-axis movement. The collet head is easily turned to the required size, and can be re-machined as necessary. Concentricities of 0.0002" can typically be achieved using Royal 5C Expanding Collets. These collets are manufactured from 1144 steel that can be hardened after machining for wear resistance.
