Description

Harlingen 9742-3059 15/16″ High Precision 5C Collet is a professional-grade workholding tool designed for precise and secure clamping in lathes, milling machines, and grinding operations. Constructed from high-grade tool steel, this collet delivers long-lasting durability and consistent performance. 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 throughout protects the spindle connection while maintaining exceptional accuracy. Internal and external thread machining after heat treatment minimizes deformation and burrs, providing smooth and reliable threaded engagement for high-precision machining tasks.
