Lyndex-nikken 160-025 Round Collet 25/64 Inch 4.31 Oal

Product Description

The LYNDEX-NIKKEN 160-025 is a round collet designed for precision workholding in CNC machining and toolholding applications. It accepts a 25/64-inch bore size and features a 1-11/16-20 internal thread with an M47.5 x 1.75 external thread, making it compatible with standard collet chuck bodies that accept this thread specification. The overall length measures 4.31 inches and the total indicated runout (TIR) is rated at 0.0007 inches, supporting tight-tolerance turning, milling, and grinding operations. Machinists and CNC setup technicians are the primary installers of this component. At 2.25 pounds, it is a solid, precision-ground tool that holds dimensional stability under production conditions.

This round collet is suited for use in production machine shops, job shops, and toolrooms running CNC lathes, machining centers, or manual machines equipped with compatible collet chucks. It is typically deployed in applications requiring repeatable part clamping, concentricity, and runout control. The 25/64-inch bore size makes it appropriate for workpieces or tooling shanks of that specific diameter. This part is intended for professional machining environments where accurate, repeatable workholding directly affects part quality and cycle time.

Installation Notes

Installation is performed by qualified machinists or CNC technicians. Always power down and lock out the machine spindle before installing or removing a collet. Ensure the collet bore, chuck body threads, and mating surfaces are clean and free of chips or debris before seating the collet. Do not overtighten the collet nut beyond the chuck manufacturer's specified procedure, and inspect the collet and chuck body for wear or damage at regular service intervals.
