High precision ER16 collets compliant with DIN 6499 are engineered for advanced tool clamping in CNC machines, machining centers and automatic lathes. Designed to deliver superior concentricity and repeatability, these collets are manufactured from high-alloy steel, hardened and ground to ensure geometric stability and long service life under demanding operating conditions.

The working principle is based on controlled elastic deformation, allowing uniform clamping across the entire tool surface. This reduces transmission play and minimizes vibration, improving machining quality while extending tool and spindle life.

Available versions include differentiated clamping ranges, with narrower ranges for high-precision applications and wider ranges for increased flexibility. This enables optimal performance depending on the machining requirement, balancing precision and versatility.

These collets are particularly suitable for milling, drilling, boring and tapping operations, including applications with through-coolant systems. The high concentricity directly contributes to reducing geometric errors, improving tolerances, surface finish and process stability.

From an application standpoint, they are widely used in high-demand industries such as automotive, aerospace, precision engineering and complex component manufacturing. They also play a key role in quality control processes where dimensional repeatability is critical.

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