Lyndex-nikken 163-044 Hex Collet 11/16 Inch

Product Description

The LYNDEX-NIKKEN 163-044 is a hex collet designed for precision workholding in CNC machining and toolholding applications. It accepts 11/16-inch hex stock and features a 1-11/16-20 internal thread with an M47.5 x 1.75 external thread for secure chuck or collet body engagement. With a total indicator runout (TIR) of 0.0011 inches, this collet delivers the concentricity required for accurate turning and milling of hex-profile workpieces. Overall length is 4.31 inches. It is suited for production shops running hex bar stock or hex-shank tooling where tight runout tolerances are necessary.

This hex collet is used in manual and CNC lathes, turning centers, and collet chuck systems where hex geometry must be gripped concentrically. Typical applications include machining hex fasteners, hex bar stock, and hex-shank cutting tools in both job shop and production environments. Installation is performed by machinists and toolroom technicians setting up collet chucks or toolholding systems that accept the M47.5 x 1.75 external thread interface.

Compatibility

Designed for use in collet chuck systems that accept the M47.5 x 1.75 external thread and 1-11/16-20 internal thread interface, as specified by the manufacturer for this hex collet series.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before inserting or removing the collet. Ensure mating chuck threads and collet seating surfaces are clean and free of chips or debris before assembly. Follow the machine tool and collet chuck manufacturer torque and clamping guidelines when securing the collet body.
