Description
Harlingen 9742-3061 31/32″ High Precision 5C Collet is a high-accuracy tool holding solution designed for precision machining and industrial applications. Crafted from high-grade tool steel, it delivers durability and long service life. With a run-out accuracy of ≤0.0006″ at 3 x D and a surface roughness of Ra 0.4, this collet ensures precise and stable operation. The “STEP” hardened and ground surface protects spindle connections while maintaining high accuracy. Internal and external thread machining after heat treatment reduces deformation and burrs, providing smooth, reliable threaded engagement for consistent performance.
