They are necessary when: concentricity is critical (precision manufacturing on shafts, gears), workpieces are small (Ø 3–26 mm) and the jaw cannot grip effectively, working in series with identical workpieces to be loaded quickly. Disadvantage: each diameter requires its specific collet (sold separately).\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eThe collet chuck + 5C collet combination — what can be clamped?\u003c\/summary\u003e\n\u003cp\u003e5C collets accept cylindrical workpieces from 3 to 26 mm. Each collet is specific for a diameter (e.g., 10 mm collet for Ø 10 mm bars). Purchase collets of the diameter corresponding to your workpieces — sold separately in sets or individually.
