Lyndex-nikken 160-007 Round Collet 7/64 Inch

Product Description

The LYNDEX-NIKKEN 160-007 is a round collet designed for precision CNC machining and toolholding applications. It accepts a 7/64 inch tool shank and features a 1-11/16 inch-20 internal thread with an M47.5 x 1.75 external thread for secure mounting in compatible collet chucks. The overall length of 4.31 inches suits deep-reach and standard spindle configurations alike. Total indicated runout (TIR) is rated at 0.0007 inches, making it suitable for operations where concentricity directly affects surface finish and tool life. Machinists and CNC setup technicians rely on collets at this tolerance class for milling, drilling, and light boring work.

This collet is intended for use in industrial CNC machining centers and manual milling machines that accept the corresponding external thread specification. Its 7/64 inch bore size targets small-diameter cutting tools used in precision die work, mold making, and fine detail machining. The threaded interface is designed for use in collet chuck bodies that match the M47.5 x 1.75 external thread standard. This is a single-piece unit sold individually and is a direct replacement or spare for shops running LYNDEX-NIKKEN collet chuck systems.

Compatibility

Designed for use in collet chuck bodies accepting an M47.5 x 1.75 external thread interface. Consult the chuck manufacturer specifications to confirm thread and bore compatibility before installation.

Installation Notes

Installation should be performed by a qualified machinist or CNC toolroom technician. Ensure the spindle is fully stopped and the machine is powered down before handling or seating the collet. Clean all mating threads and seating surfaces before assembly to prevent runout error caused by debris or burrs. Do not exceed the chuck manufacturer torque recommendations when tightening the collet nut.
