Product overview Rim-Lok’s Collet Chuck line of standard collet chucks provides a fast, flexible, and cost-effective answer to workholding needs. Designed for second and final turning operations, the Rim-Lok operates as a pull-back style chuck compatible with most standard CNC lathes and can be actuated using the machine’s primary cylinder. Manufactured by Forkardt with a proprietary material selection and heat-treating process, these collet chucks offer extended life, reduced changeover and downtime, and consistent part holding. Forkardt collets deliver repeatability of 0.0005" TIR (0.013 mm) or better, ensuring stable clamping throughout machining operations.

Advantages
