ER Collet Chucks • ER Spring Collet • End Mill Collets

Discover the exceptional qualities of our ER collet collection, crafted from high-carbon bearing steel (SUJ2). After undergoing heat treatment, this material strikes a perfect balance between hardness and toughness, ensuring remarkable wear resistance and an extended lifespan due to enhanced elasticity. With a hardness of HRC46° and a surface roughness within RA1.5, our ER Spring Collet are engineered to meet the highest standards of precision.

From ER8 to ER11, ER16, 20, 25, 32, and 40, our collets offer versatile clamping ranges – 1mm to 32mm. They accommodate contraction ranges of 1mm for hole diameters below 2.5mm and 2mm for hole diameters above 10mm, ensuring adaptability across various applications.

Our concentricity is rigorously inspected according to DIN standards, resulting in two accuracy levels: A Grade (0.01mm), and AA Grade (0.005mm). For enhanced stability, we recommend pairing AA Grade collets with HSP nuts.

These ER-series End Mill Collets are ideal for securely clamping drills, tapping screws, milling cutters, reamers, and a wide range of tools. Their elastic expansion and contraction features make them versatile, catering to a broad spectrum of applications.
