Lyndex-nikken 160-032 Round Collet 1/2 Inch

Product Description

The LYNDEX-NIKKEN 160-032 is a round collet designed for precision toolholding in CNC machining and rotating spindle applications. Built to accept a 1/2-inch tool shank, it features a 1-11/16-20 internal thread and an M47.5 x 1.75 external thread for secure engagement with compatible collet chucks. The overall length (OAL) is 4.31 inches. Total indicator runout (TIR) is rated at 0.0011 inches, supporting tight tolerances in milling, drilling, and reaming operations. This collet is installed by machinists and toolroom technicians working in production or job-shop environments where repeatable tool positioning is critical.

The 160-032 round collet suits vertical and horizontal CNC machining centers where collet-style toolholding is preferred over end-mill holders or shrink-fit systems. It is appropriate for shops running high-rotation-speed spindles that require minimal runout to maintain part quality and extend cutting tool life. The 1/2-inch bore size accommodates a broad range of standard shank cutting tools used across general metalworking and precision machining applications.

Key Features

• 1/2-inch bore accepts standard round-shank cutting tools
• 0.0011-inch TIR rating supports tight-tolerance machining operations
• 4.31-inch OAL provides reach suitable for typical spindle-collet chuck setups
• 1-11/16-20 internal thread for secure collet-to-chuck engagement
• M47.5 x 1.75 external thread for compatibility with matched collet chuck bodies
• Weighs 2.25 pounds - solid construction for rigidity under cutting loads

Compatibility

Designed for use with collet chuck bodies accepting M47.5 x 1.75 external thread engagement and 1-11/16-20 internal thread specification. Verify chuck body thread specification before installation. No additional specific model compatibility data was provided in the product input.

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 from the chuck body. Use the appropriate spanner wrench rated for the collet nut torque specification - do not use improvised tools that could damage the thread engagement surfaces. Inspect the collet bore and seating taper for chips or contamination before assembly, as debris will increase runout and reduce clamping force.
