High-Torque SK Precision Collets

SK collets are intended for applications where torque transfer is the main limitation of a conventional ER system. Their geometry raises torque output to about 1.5 times that of an ordinary ER collet while maintaining stable clamping accuracy.

ER Precision Collets for CNC Tool Holders

ER collets provide the broad-use option within Haozhi's precision-collet range. Multiple accuracy grades address different runout requirements, while the familiar ER format supports boring, milling, drilling, tapping, grinding and engraving tools.
