ER/SG Drill collets

Drill machine collets are made from SUJ2 high-carbon bearing steel and heat-treated for exceptional hardness, toughness, and wear resistance, extending the collet's service life.

Our collets achieve a hardness of HRC46° and a surface finish within RA1.5, providing superior grip and improved stability.

ER drill collets are suitable for straight-shank drill bits and milling cutters.

SG drill collets are suitable for milling-shank drill bits and milling cutters and are less prone to interference.
