Lyndex-nikken 330-036 Hex Collet 9/16 Inch

Product Description

The LYNDEX-NIKKEN 330-036 is a hex collet designed to hold hex-shank tooling securely in compatible collet chucks and toolholding systems. With a 9/16 inch hex capacity, a 1.988-20 external thread, and an overall length of 3-3/4 inches, this collet provides a positive, non-rotating grip on hex-drive tools during machining operations. It is used in CNC machining centers and manual machine tool setups where hex tooling must be held with precision and repeatability. The part weighs 1.72 pounds and is sold individually.

This hex collet is suited for production machining environments where hex-shank tools such as drill bits, taps, and form tools need to be driven without slippage. The hex bore geometry prevents rotation under load, making it a practical choice for tapping and driving operations on machining centers. It is appropriate for both job shop and high-volume production settings where toolholding consistency is critical to part quality and cycle time.

Key Features

• 9/16 inch hex bore provides a positive, anti-rotation grip on hex-shank tooling
• 1.988-20 external thread for compatibility with matching collet chuck bodies
• 3-3/4 inch overall length suits standard toolholding reach requirements
• Precision-ground construction consistent with LYNDEX-NIKKEN toolholding standards
• Sold as a single unit for targeted replacement or system expansion

Compatibility

Designed as an OEM-style replacement or supplementary collet for toolholding systems that accept 1.988-20 external thread hex collets. Consult the chuck body manufacturer specifications to confirm thread and collet series compatibility before installation.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician familiar with collet chuck assembly procedures. De-energize and lock out the machine spindle before inserting or removing the collet. Ensure the chuck body threads and collet threads are clean and free of chips or burrs before assembly. Do not exceed the toolholding system manufacturer rated clamping torque specifications.
