Lyndex-nikken 160-038 Round Collet 19/32 Inch 4.31 Oal

Product Description

The LYNDEX-NIKKEN 160-038 is a round collet designed for precision workholding in CNC machining and toolholding applications. It features a 19/32-inch bore size, a 1-11/16-20 internal thread, and an M47.5 x 1.75 external thread. The overall length is 4.31 inches. Total indicator runout (TIR) is held to 0.0011 inches, making this collet suitable for applications where concentricity and repeatability are critical. Machinists and toolroom technicians install this collet into compatible collet chucks or toolholding systems to secure cutting tools or workpieces during turning, milling, or grinding operations.

This collet is used in machine shop environments - both production and job shop settings - where precise tool clamping is required. Its round collet design suits standard rotary toolholding configurations. The combination of inch internal threading and metric external threading accommodates toolholder bodies that mix inch and metric interface standards, a common requirement in facilities running mixed equipment inventories. Installation is performed by qualified machinists or toolroom personnel familiar with collet chuck assembly procedures.

Key Features

• 19/32-inch bore size for matching tool shank diameter
• TIR of 0.0011 inches for high concentricity and repeatability
• 1-11/16-20 internal thread for secure chuck engagement
• M47.5 x 1.75 external thread for metric toolholder body compatibility
• 4.31-inch overall length for standard collet chuck reach requirements
• Round collet design for uniform radial clamping force

Compatibility

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

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician with the machine powered down and any rotating spindle fully stopped before handling collet components. Clean the collet seat and mating surfaces before installation to ensure proper seating and accurate TIR. Use the appropriate collet wrench or spanner for the thread interface - do not use pipe wrenches or improvised tools that may damage the thread or collet body. Verify runout with a dial indicator after installation before returning the machine to service.
