Lyndex-nikken 160-064 Round Collet 1 Inch

Product Description

The LYNDEX-NIKKEN 160-064 is a round collet designed for precision workholding in CNC machining and milling applications. It features a 1-inch bore size, a 1-11/16-20 internal thread, and an M47.5 x 1.75 external thread, making it compatible with collet chucks that accept this thread specification. With an overall length of 4.31 inches and a total indicator runout (TIR) of 0.0011 inches, this collet delivers the tight tolerances required for high-accuracy turning, milling, and toolholding operations. Installation is performed by qualified machinists or toolroom technicians in production and job-shop environments.

This collet is suited for use in CNC machining centers, manual mills, and lathes where a round collet chuck with M47.5 x 1.75 external thread engagement and 1-11/16-20 internal thread interface is specified. It handles 1-inch round stock or tooling shanks and is appropriate for both production runs and precision one-off setups in metalworking and industrial machining environments where runout control is critical.

Key Features

• 1-inch bore size for standard round workpieces and tooling shanks
• TIR of 0.0011 inches for precision, low-runout workholding
• 1-11/16-20 internal thread for secure chuck engagement
• M47.5 x 1.75 external thread for compatibility with matching collet chuck bodies
• 4.31-inch overall length suits standard collet chuck assemblies

Compatibility

Designed for use with collet chuck systems that accept M47.5 x 1.75 external thread collets and a 1-11/16-20 internal thread interface, for 1-inch round bore applications.

Installation Notes

Installation is performed by a machinist or toolroom technician. Ensure the spindle or collet chuck is fully de-energized and brought to a complete stop before handling or seating the collet. Clean the chuck body and collet taper surfaces before installation to prevent runout caused by debris. Torque the collet nut according to the chuck manufacturer specifications - do not over-tighten, as this can damage the collet or thread engagement.
