The ER11 self-extracting collets DIN 6499 B type 050 are a professional toolholding solution designed for high-precision machining applications. The ER11 size is specifically optimized for small diameter tools, where runout control, stability, and vibration reduction are critical to achieving high-quality machining results.

The self-extracting system enables quick and controlled tool release from the collet nut, significantly improving setup efficiency and operational safety. This feature is especially valuable in high-productivity CNC environments and repetitive machining cycles, where tool change time directly impacts overall performance.

The slot geometry, designed according to DIN 6499 B standards, ensures uniform clamping force distribution along the entire contact surface, minimizing transmission play. This results in improved control of geometric and form errors, enhancing surface finish quality and process repeatability.

The typical ER11 clamping range provides flexibility for different tool diameters while maintaining high system rigidity. The ability to compensate micro dimensional variations ensures stable performance in finishing operations and high-speed machining, where even minimal runout can affect the final result.

Manufactured from high-alloy hardened and ground steel, ER11 self-extracting collets offer excellent wear resistance and long service life. The precision grinding process ensures optimal contact surfaces, improving torque transmission and clamping accuracy.

These collets are widely used in milling, drilling, and tapping operations and are ideal for controlling dimensions, heights, runout, and mechanical play in precision machining. They are particularly suitable for machine tool manufacturers, precision workshops, and quality control departments in automotive and advanced engineering sectors.
