The EOC25 collets according to DIN ISO 10897 (DIN 6388) are designed for clamping cylindrical tools in applications requiring high rigidity, stability, and geometric precision. The low taper design, combined with an extended clamping length, ensures highly efficient torque transmission, significantly reducing elastic deformation, vibration, and clamping play.

With a length of 52 mm and a clamping range from D2 to D25 mm, EOC25 collets are particularly suitable for heavy-duty machining and high-load milling operations, where system rigidity directly affects surface finish quality and dimensional accuracy.

The 6+6 bilateral slot configuration ensures uniform clamping force distribution across the entire contact surface, improving concentricity and reducing form and geometry deviations. A runout accuracy of ≤ 0.008 mm enables precise control of radial deviation, which is essential in precision machining and quality control processes.

The clamping capability up to 0.5 mm below the nominal diameter provides operational flexibility while maintaining high stability and safety standards. The surface finish with roughness Rz 1.6 enhances contact between the collet and the tool shank, optimizing pressure distribution and minimizing slippage under demanding working conditions.

EOC25 collets are widely used in automotive, precision engineering, industrial production, and maintenance environments, making them ideal for CNC operators, engineers, and machine tool manufacturers requiring high performance and long-term reliability in heavy machining applications.
