Lyndex-nikken 163-080 Hex Collet 1-1/4 Inch

Product Description

The LYNDEX-NIKKEN 163-080 is a hex collet designed for precision workholding in CNC machining and toolholding applications. It accepts a 1-1/4 inch hex shank and features a 1-11/16 inch-20 internal thread along with an M47.5 x 1.75 external thread for secure engagement with compatible collet chucks and adapters. The overall length measures 4.31 inches, and the total indicator runout (TIR) is rated at 0.0011 inches, supporting tight-tolerance machining operations. This collet is installed by machining technicians and toolroom personnel working with hex-drive tooling setups where repeatable accuracy is required.

The 163-080 hex collet is suited for use in machining centers and turning applications where hex shank tooling must be gripped with consistent concentricity. It is appropriate for both production and job-shop environments running hex-drive tooling in collet chuck systems. Technicians select this collet when working with toolholding systems that accept the M47.5 x 1.75 external thread standard, making it a direct-fit solution for compatible collet bodies in that thread class.

Key Features

• 1-1/4 inch hex collet size for secure grip on hex shank tooling
• 1-11/16 inch-20 internal thread for proper chuck engagement
• M47.5 x 1.75 external thread for compatibility with corresponding collet bodies
• 4.31 inch overall length provides standard reach in collet chuck assemblies
• 0.0011 inch TIR rating supports precision, low-runout toolholding requirements

Compatibility

Designed for use with collet chuck systems accepting an M47.5 x 1.75 external thread and a 1-11/16 inch-20 internal thread interface. Confirm thread class and collet body specifications before installation.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the collet chuck is removed from the spindle or secured before handling collets. Inspect threads on both the collet and the collet body for damage or debris prior to assembly. Use the appropriate spanner or collet wrench to achieve proper seating - do not use impact tools on collet threads.
