Description

Harlingen 9742-3068 1-5/64″ High Precision 5C Collet offers outstanding precision and durability for high-accuracy machining and workholding applications. Made from high-grade tool steel, this 5C collet provides a run-out accuracy of ≤0.0006″ at 3 x D. The “STEP” hardened and ground surfaces protect the spindle connection while ensuring high accuracy, long-term durability, and extended tool life. Internal and external thread machining is performed after heat treatment to minimize deformation and burrs, providing smooth and reliable threaded engagement. Surface roughness is Ra 0.4 for consistent clamping performance.
