Lyndex-nikken 163-024 Hex Collet 3/8 Inch

Product Description

The LYNDEX-NIKKEN 163-024 is a hex collet designed to hold hexagonal stock or tooling in CNC turning and machining centers. It accepts 3/8 inch hex material and features a 1-11/16 inch-20 internal thread along with an M47.5 x 1.75 external thread for secure mounting in compatible collet chucks or collet closers. Overall length measures 4.31 inches. Total indicator runout (TIR) is rated at 0.0007 inches, supporting close-tolerance turning operations where concentricity is critical. Machinists and CNC operators install this collet when production runs require consistent hex-stock feeding or secondary operations on hex-profile workpieces.

This collet is suited for use in production machine shops running CNC lathes or turning centers equipped with collet chuck systems that accept the M47.5 x 1.75 external thread interface. Typical applications include bar-feeding hex stock for fastener machining, fitting work, and other turned components where a hex grip profile is required. Its 3/8 inch hex capacity covers a common stock size used across light industrial and precision machining environments.

Key Features

• 3/8 inch hex collet capacity for secure grip on hex-profile stock and tooling
• 0.0007 inch TIR for close-tolerance, high-concentricity turning operations
• 1-11/16 inch-20 internal thread for compatibility with standard collet closer systems
• M47.5 x 1.75 external thread interface for collet chuck mounting
• 4.31 inch overall length provides adequate reach in standard turning setups
• Weighs 1.7 pounds for stable mass without excessive spindle load

Compatibility

Designed for collet chuck systems and collet closers that accept an M47.5 x 1.75 external thread and a 1-11/16 inch-20 internal thread interface. Confirm thread specifications against your machine spindle or chuck nose before installation.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician with the machine spindle fully stopped, control in E-stop, and all power isolated per shop lockout/tagout procedures. Clean all mating threads and seating surfaces before assembly to ensure accurate TIR. Do not exceed the torque or clamping specifications published by the machine or chuck manufacturer. Verify runout with a dial indicator after installation before resuming production cuts.
