ER SPRING COLLET

The ER Spring Collet is a precision workholding component designed to provide accurate, secure, and concentric clamping of cutting tools in CNC machining centers, milling machines, drilling machines, and lathes. Manufactured from high-grade spring steel and hardened through advanced heat-treatment processes, ER collets offer excellent elasticity, wear resistance, and long service life. Their unique slotted design ensures uniform 360° clamping pressure, delivering superior gripping force while minimizing tool runout and vibration. Precision grinding guarantees high concentricity, resulting in improved machining accuracy, enhanced surface finish, and extended tool life. ER Spring Collets are available in various sizes to accommodate a wide range of tool shank diameters, making them suitable for end mills, drills, reamers, taps, and other rotary cutting tools. Compatible with standard ER collet chucks, they provide quick tool changes, reliable performance, and consistent clamping, making them an ideal choice for high-speed, precision, and production machining applications.
