High force SR

SR cylindrical collets with 4 slots are engineered for high-performance tool clamping in power milling chucks, delivering superior stability, precision, and process reliability in demanding industrial applications. The four-slot design ensures uniform clamping force distribution across the entire contact surface, minimizing transmission play and enhancing the overall rigidity of the tool-holder system.

With a runout accuracy of ≤ 0.005 mm, these collets enable high-precision machining even in critical operations such as finishing, grinding, deburring, and high-speed machining. The tool is clamped along the full effective length of the collet, ensuring a stable and repeatable interface while significantly reducing geometric deviations and form errors.

Designed for tools with shank h6 tolerance, SR collets guarantee optimal fit and dimensional control throughout the machining process. Key dimensional parameters such as length L, diameters A and A2, and clamping range D allow precise integration with power milling chucks, ensuring compatibility across various machine configurations.

The integrated mechanical sealing system enables internal coolant supply up to 120 bar, improving heat dissipation, chip evacuation, and machining stability under heavy-duty conditions. This results in extended tool life, reduced vibration, and enhanced surface finish quality.

These collets are widely used in automotive, precision engineering, mold manufacturing, and high-performance CNC machining environments, making them a reliable solution for professionals seeking maximum clamping performance and process control.
