Description

Harlingen 9742-3006 7/64″ High Precision 5C Collet is a precision tool designed for secure and accurate workholding in lathes, milling machines, and grinding applications. Made from high-grade tool steel, this collet offers exceptional durability and long service life. It features a run-out accuracy of ≤0.0006″ at 3×D and a surface roughness of Ra 0.4, ensuring precise alignment of workpieces. The “STEP” hardened and ground surface protects the connection with the spindle while maintaining high accuracy and reliability. Internal and external thread machining after heat treatment minimizes deformation and burrs, providing smooth and consistent threaded engagement for professional machining tasks.
