Lyndex-nikken 330-024 Hex Collet 3/8 Inch

Product Description

The LYNDEX-NIKKEN 330-024 is a hex collet designed to grip hex-shank tooling in CNC machining centers, lathes, and milling applications. It accepts a 3/8 inch hex drive and features a 1.988-20 external thread for secure mounting in compatible toolholders. The overall length measures 3-3/4 inches. This collet is used by machinists and tool-and-die professionals requiring precise, repeatable grip on hex-profile cutting tools or drivers. Proper collet fit is critical for runout control and tool life, making this a workholding component that demands accurate sizing before ordering.

This hex collet is suited for use in production machining environments where hex-drive tooling must be held rigidly in a rotating spindle or toolholder assembly. It is typically installed in machining centers running tapping, drilling, or driving operations that call for hex-shank tool retention. The 1.988-20 external thread engagement ensures the collet seats firmly within its corresponding nut or holder body. Applications span both job-shop and production-floor settings where consistent torque transmission and concentricity are required.

Key Features

• 3/8 inch hex bore for direct hex-shank tool retention
• 1.988-20 external thread provides secure holder engagement
• 3-3/4 inch overall length suits standard toolholder depth requirements
• Designed for CNC machining, tapping, and hex-drive tooling applications
• Single-piece construction for consistent grip and reduced runout

Compatibility

Designed as an OEM-style hex collet for use with toolholders accepting a 1.988-20 external thread and a 3/8 inch hex collet bore.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is in a locked-out, de-energized state before changing collets. Inspect the collet bore and mating holder threads for debris or damage before seating. Do not force the collet into the holder; thread engagement should be smooth and free of binding.
