Description
Harlingen 9742-3058 59/64″ High Precision 5C Collet provides exceptional precision and durability for demanding machining and workholding tasks. Constructed from high-grade tool steel, this 5C collet delivers outstanding accuracy with a run-out of ≤0.0006″ at 3 x D. The “STEP” hardened and ground surfaces protect the connection with the spindle while maintaining high accuracy, long-term durability, and extended tool life. Internal and external thread machining is performed after heat treatment to reduce deformation and burrs, ensuring smooth and reliable threaded engagement. Surface roughness is Ra 0.4 for consistent clamping performance.
