Description

Harlingen 9742-3064 1-1/64″ High Precision 5C Collet is a precision workholding tool designed for secure and accurate clamping in lathes, milling machines, and grinding applications. Constructed from high-grade tool steel, this collet provides long-lasting durability and reliable 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 protects the spindle connection while maintaining high accuracy. Internal and external thread machining after heat treatment minimizes deformation and burrs, offering smooth and consistent threaded engagement for professional machining tasks.
