Lyndex-nikken 160-045 Round Collet 45/64 Inch

Product Description

The LYNDEX-NIKKEN 160-045 is a round collet designed for precision CNC toolholding applications. It accepts a 45/64-inch workpiece or tool shank and features a 1-11/16-20 internal thread with an M47.5 x 1.75 external thread for secure chuck engagement. Overall length is 4.31 inches. The total indicator runout (TIR) is rated at 0.0011 inches, making this collet suitable for operations where concentricity and repeatability directly affect part tolerances. At 2.24 pounds, it is built for the rigors of production-floor use. Licensed machinists and CNC setup technicians are the primary installers of this component.

This round collet is used in machining centers and turning applications where a collet chuck system requiring M47.5 x 1.75 external thread engagement is specified. Typical installations are found in production and job-shop environments running milling, drilling, or light turning operations that demand close TIR tolerances. The 45/64-inch bore size makes it appropriate for holding round-shank cutting tools or workpieces of that specific diameter.

Key Features

• 45/64-inch bore size for precise round-shank tool or workpiece holding
• 0.0011-inch TIR for high concentricity in close-tolerance machining
• 1-11/16-20 internal thread for compatibility with matching collet chuck bodies
• M47.5 x 1.75 external thread for secure chuck engagement
• 4.31-inch overall length provides ample engagement depth
• 2.24-pound construction suited for production-floor rigors

Compatibility

Designed for use in collet chuck systems that accept M47.5 x 1.75 external thread round collets with a 1-11/16-20 internal thread interface. Verify chuck body thread specifications before installation.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the chuck body is clear of the machine before threading the collet into the chuck. Threads should be clean and free of chips or coolant residue before engagement. Torque to chuck manufacturer specifications only - do not use impact tools on collet threads.
