Lyndex-nikken 330-060 Hex Collet 15/16 Inch

Product Description

The LYNDEX-NIKKEN 330-060 is a hex collet designed to grip hex-shank tooling in compatible collet chucks and toolholding systems. With a 15/16-inch hex size and an overall length (OAL) of 3.75 inches, this collet provides secure, repeatable tool engagement for machining operations. The 1.988-20 external thread allows for precise installation into the collet nut. Weighing 1.87 pounds, this is a solid, production-grade component suited for use by machinists and tool-crib personnel in CNC and manual machining environments.

This hex collet is intended for use in milling, drilling, and tapping applications where hex-shank tooling must be held rigidly and concentrically. It fits into toolholding systems that accept the 1.988-20 external thread spec. Typical install scenarios include production machining cells, job shops, and toolroom setups requiring consistent hex-drive tool retention. Installation and tool changeouts are performed by machinists or toolroom technicians familiar with collet chuck systems.

Compatibility

Designed as an OEM-style replacement or direct-fit collet for toolholding systems that accept a 1.988-20 external thread hex collet with a 15/16-inch bore size.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before removing or installing any collet. Thread the collet into the collet nut by hand first to confirm thread engagement before applying a torque wrench or spanner. Inspect the collet bore and seating surfaces for chips or debris before each installation to maintain concentricity and prevent premature wear.
