Lyndex-nikken 330-080 Hex Collet 1-1/4 Inch 1.988-20 Thread

Product Description

The LYNDEX-NIKKEN 330-080 is a hex collet designed for precision workholding applications in CNC machining and toolholding systems. It accepts a 1-1/4 inch hex workpiece and features a 1.988-20 external thread for secure mounting into compatible collet chucks or holders. With an overall length of 3-3/4 inches, this collet provides stable grip geometry suited to demanding turning and milling operations. Machinists and toolroom technicians working with hex-profile stock or tooling will find this collet a direct-fit solution for maintaining accurate positioning and repeatable clamping force.

This hex collet is intended for use in industrial machining environments where hex-profile workpieces or tools require secure, concentric clamping. Typical applications include CNC lathes, machining centers, and manual toolroom setups where the 1.988-20 external thread standard is specified. It is appropriate for both production runs and precision toolroom work where consistent grip on hex geometry is required.

Key Features

• 1-1/4 inch hex bore size for direct clamping of hex-profile workpieces or tooling
• 1.988-20 external thread for compatibility with matching collet chuck systems
• 3-3/4 inch overall length provides extended support and stable workholding
• Precision-ground hex geometry for repeatable, accurate clamping
• Single-piece construction suitable for high-cycle production environments

Compatibility

Designed as an OEM-style replacement or direct-fit collet for toolholding systems that accept the 1.988-20 external thread standard with a 1-1/4 inch hex bore specification.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully powered down and at a complete stop before removing or installing any collet. Verify thread engagement is clean and free of chips or debris before seating the collet in the holder. Do not exceed the clamping torque specifications listed by the collet chuck manufacturer.
