High precision ER32 collets compliant with DIN 6499 are designed to provide extremely stable, accurate and repeatable tool clamping in CNC machines, machining centers and automatic lathes. Manufactured from high-alloy steel, hardened and ground, they ensure excellent geometric stability, wear resistance and consistent performance under demanding machining conditions.

Their operating principle is based on controlled elastic deformation, allowing uniform clamping force distribution across the entire tool surface. This significantly reduces transmission play and vibration, improving machining quality and minimizing form and positional errors.

Available versions differ by clamping range. Narrow range collets (2.5–3.0 mm) are optimized for ultra-high precision applications where maximum concentricity is required. Wider range versions (4.0–20.0 mm) provide greater flexibility, covering a wide range of tool diameters with a single collet while maintaining high industrial precision.

These collets are suitable for milling, drilling, boring and tapping operations, including applications with through-coolant systems. Clamping stability directly improves surface finish, dimensional accuracy and tool life.

They are widely used in automotive, aerospace, precision engineering and advanced manufacturing. They are also essential in quality control processes where repeatability directly impacts measurement reliability.

Manufactured according to DIN 6499, they ensure full compatibility with ER collet chucks and seamless integration into existing tooling systems.
