The ER60 tool clamping collet according to DIN ISO 15488 (DIN 6499) is a high-precision clamping component designed for the secure holding of cylindrical tools inside ER collet chucks used on CNC machining centers, milling machines and high-precision machine tools.

This collet belongs to Class 1 with metric bores, engineered to provide extremely reliable clamping and a uniform distribution of forces along the entire tool contact surface. The ER system is a widely recognized industrial standard due to its ability to combine precision, flexibility and high clamping rigidity, even under demanding machining conditions.

The collet body features 16 precision slots, allowing controlled elastic deformation during tightening and ensuring an even grip on the tool shank. This design maintains excellent concentricity and stability even under the dynamic loads typical of high-speed CNC machining.

The clamping range -2 mm allows each collet to cover a specific diameter range while maintaining high centering accuracy. This characteristic makes the ER system highly efficient in practical machining environments, reducing the number of collets required to cover a full tool diameter range.

The collet surface is finished with a surface roughness Rz 1.6, ensuring an optimal balance between clamping strength and protection of the tool shank, preventing damage while improving machining stability.

Thanks to its standardized geometry and high manufacturing quality, ER60 collets are widely used in milling, drilling, boring and high-precision machining operations, particularly in industries such as automotive, aerospace, mold manufacturing and precision engineering.

For technicians, production engineers and machine tool operators, using collets compliant with DIN ISO 15488 ensures reliability, repeatability and high clamping accuracy, essential factors for maintaining consistent machining quality and production efficiency.
