The 6-slot cylindrical collet series 6SR20 for hydraulic chucks is designed for high-precision clamping applications where stability, concentricity, and repeatability are critical. The six longitudinal slots ensure uniform clamping force distribution along the entire tool shank, reducing deformation, vibration, and transmission play.

This system is specifically engineered for hydraulic chucks, where clamping is achieved through controlled fluid pressure. This technology allows an average runout accuracy of 0.005 mm, making it ideal for precision machining, finishing operations, and applications requiring high surface quality.

The reduced clamping range of 0.1 mm ensures extremely precise tool holding, minimizing form errors and geometric deviations. The tool shank must be within h6 tolerance and clamped along the entire collet length to guarantee optimal force transmission and process stability.

The collet is suitable for internal coolant applications with mechanical sealing up to 120 bar. The slot geometry prevents coolant leakage, improving cooling efficiency and lubrication at the cutting zone, resulting in longer tool life and improved machining performance.

With a length of 52.5 mm and a working range from 4 to 18 mm, the 6SR20 series provides high flexibility for various production requirements. It is ideal for CNC machining, automotive production, precision engineering, and high-speed manufacturing environments.
