Lyndex-nikken 160-061 Round Collet 61/64 Inch

Product Description

The LYNDEX-NIKKEN 160-061 is a round collet designed for precision workholding in CNC machining and toolholding applications. It accepts a 61/64-inch round shank and measures 4.31 inches overall length (OAL). The internal thread is 1-11/16-20 and the external thread is M47.5 x 1.75. Total indicator runout (TIR) is rated at 0.0011 inches, making this collet suitable for applications where concentricity and repeatable tool positioning are critical. Weighing 2.12 pounds, it is a solid, precision-ground component intended for professional machine shop use.

This collet is used in milling, turning, and machining centers that require a round collet interface. It is a common replacement or additional collet for shops running LYNDEX-NIKKEN collet chucks and compatible toolholding systems. Typical installation environments include production machine shops, job shops, and toolroom applications where consistent grip force and low runout are required for finish-quality cuts or tight-tolerance work.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Power down and de-energize the machine spindle before installing or removing collets. Use the appropriate collet wrench or spanner for the thread spec - do not use pipe wrenches or improvised tools that can damage the thread or collet seating surface. Inspect the collet bore and chuck taper for chips or contamination before seating.
