Lyndex-nikken 160-040 Round Collet 5/8 Inch

Product Description

The LYNDEX-NIKKEN 160-040 is a round collet designed for precision workholding in CNC machining centers and milling applications. Sized at 5/8 inch, it features a 1-11/16 inch-20 internal thread and an M47.5 x 1.75 external thread for secure mounting in compatible collet chucks and toolholders. The overall length is 4.31 inches, and total indicated runout (TIR) is held to 0.0011 inches, supporting tight-tolerance machining operations. This collet is installed by CNC machinists and toolroom technicians working with rotating toolholding systems where concentricity and repeatability are critical to part quality.

The 160-040 round collet is suited for use in production and job-shop environments where a 5/8 inch bore diameter is required. It fits into collet chuck assemblies that accept the M47.5 x 1.75 external thread interface. Typical applications include end mill holding, drill chucking, and other rotating tool setups on vertical and horizontal machining centers. Its threaded engagement design makes it appropriate for moderate to high-speed spindle work where vibration damping and tool grip consistency matter.

Key Features

• 5/8 inch bore size for direct tool shank engagement
• 0.0011 inch TIR for high-concentricity toolholding
• 1-11/16 inch-20 internal thread for chuck body interface
• M47.5 x 1.75 external thread for collet nut retention
• 4.31 inch overall length suits standard collet chuck assemblies

Compatibility

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

Installation Notes

Installation and removal should be performed by a qualified CNC machinist or toolroom technician with the machine spindle fully stopped and locked out per applicable OSHA lockout/tagout procedures. Use the correct collet wrench and nut spanner for the thread size to avoid cross-threading or damage to seating surfaces. Inspect the collet bore and seating taper for chips, burrs, or wear before assembly, as contamination directly affects TIR. Do not exceed the toolholder manufacturer's recommended clamping torque range for this collet size.
