Lyndex-nikken 163-048 Hex Collet 3/4 Inch 4.31 in Oal

Product Description

The LYNDEX-NIKKEN 163-048 is a hex collet designed for precision workholding in CNC machining and toolholding applications. It accepts 3/4-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 holder engagement. The overall length is 4.31 inches, and the total indicator runout (TIR) is rated at 0.0011 inches, making it suitable for applications where concentricity and repeatability are critical. This collet is installed by machinists and toolroom technicians working with compatible collet chucks or toolholding systems.

This hex collet is intended for use in machining centers, CNC lathes, and manual machines where hex-profile workholding is required. The 3/4-inch hex size accommodates standard hex bar stock and tooling. It is a standard catalog SKU suited for production and job-shop environments where consistent grip and low runout are required for turning, milling, or secondary operations on hex-profile components.

Compatibility

Designed as an OEM-style replacement or direct-fit collet for toolholding systems that accept the M47.5 x 1.75 external thread and 1-11/16-20 internal thread specification.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the spindle or collet chuck is fully powered down and at rest before inserting or removing the collet. Clean all mating threads and seating surfaces before installation to maintain rated TIR. Do not exceed the rated clamping torque specified by the chuck manufacturer for this collet size.
