Cle-line C66716 Two Piece Adjustable Die 5/8-18 Unf

Product Description

The CLE-LINE C66716 is a two-piece adjustable threading die designed to cut 5/8-18 UNF external threads on round stock. The two-piece construction allows for fine adjustment of thread fit and cutting depth, making it suitable for both roughing and finishing passes in a single setup. Built from carbon steel, this die fits a Collet 5 die stock and weighs 0.156 pounds. It is a standard tool for threading operations on mild steel, aluminum, and similar machinable materials in production and maintenance settings.

This die is suited for threading 5/8-inch diameter fasteners, fittings, studs, and shafts to the UNF 18-threads-per-inch standard. Typical applications include machine shops, maintenance facilities, and industrial assembly environments where precise external thread cutting is required. The adjustable design gives the technician control over thread tolerance, which is especially useful when working with worn or oversized stock that requires a custom thread fit.

Key Features

• Two-piece adjustable design allows fine-tuning of thread cutting depth and fit tolerance
• 5/8-18 UNF thread size for standard unified fine thread applications
• Carbon steel construction provides durability for general threading work
• Collet 5 sizing for use with compatible die stocks and holders
• Lightweight at 0.156 pounds for easy handling during bench work

Compatibility

Designed for use with Collet 5 die stocks and holders that accept two-piece adjustable dies for 5/8-18 UNF threading applications.

Installation Notes

This die is installed and operated by machinists or maintenance technicians using a compatible Collet 5 die stock. Secure the die properly in the stock before beginning any threading operation. Apply appropriate cutting fluid to the workpiece to extend die life and improve thread finish. Inspect the die for wear or chipping before each use and replace if thread quality is compromised.
