Harlingen 7/8″ High Precision 5C Collet (9742-3055)

Description

Harlingen 9742-3055 7/8″ High Precision 5C Collet provides reliable and accurate holding for precision machining applications. Made from high-grade tool steel, this collet ensures long-lasting durability and performance. The run-out accuracy is ≤0.0006″ at 3 x D, and the surface roughness is Ra 0.4 for superior precision. “STEP” hardened and ground surfaces protect the spindle connection while maintaining high accuracy. Internal and external threads are machined after heat treatment, reducing deformation and burrs, resulting in smooth and consistent threaded engagement for professional and workshop use.

Features:

• High-grade tool steel construction for strength and durability.
• Run-out accuracy ≤0.0006″ at 3 x D for precision machining.
• Surface roughness Ra 0.4 ensures smooth operation.
• “STEP” hardened and ground surface for spindle protection and accuracy.
• Internal and external threads machined after heat treatment to reduce deformation and burrs.
• Ensures smooth and precise threaded engagement.

Benefits:

• Maintains high precision for professional machining and tooling applications.
• Durable design extends tool life and reduces wear.
• Minimizes errors and vibration during operation due to low run-out.
• Heat-treated threads provide smooth, reliable connection with spindle.
• Ideal for high-accuracy applications in metalworking and workshops.
