Harlingen 57/64″ High Precision 5C Collet (9742-3056)

Description

Harlingen 9742-3056 57/64″ High Precision 5C Collet is engineered for high-accuracy holding of tools and workpieces in machining applications. Made from high-grade tool steel, this collet provides excellent durability and long tool life. It features a run-out accuracy of ≤0.0006″ at 3 x D and a surface roughness of Ra 0.4 for smooth operation. The “STEP” hardened and ground surface protects the connection with the spindle while ensuring precision and stability. Internal and external thread machining after heat treatment minimizes deformation and burrs, offering smooth, reliable threaded engagement for consistent performance in precision work.
