Cle-line C66715 Two Piece Adjustable Die 5/8-11 Unc

Product Description

The CLE-LINE C66715 is a two-piece adjustable threading die designed to cut external threads on rod, bar stock, and fastener blanks. Built from carbon steel, this die accepts a Collet 5 die holder and is sized for the 5/8-11 UNC thread specification, which is one of the most common coarse-thread standards in general mechanical work and structural fastener applications. The two-piece design allows the cutting diameter to be adjusted incrementally, enabling the user to take multiple light passes or fine-tune thread fit to tolerance. Licensed machinists, tool and die technicians, and industrial maintenance professionals are the primary installers and users of this type of tooling.

This die is suited for production and maintenance threading operations where a 5/8-11 UNC external thread is required. It fits into a Collet 5 style die stock and is appropriate for use on carbon steel, mild steel, and similar ferrous stock materials. The adjustable two-piece configuration makes it practical for both initial thread cutting and chasing worn or damaged threads in repair applications.

Key Features

• Two-piece adjustable design allows fine diameter adjustment for thread fit control
• 5/8-11 UNC thread specification - coarse pitch, fractional inch standard
• Collet 5 die holder compatibility for use with standard die stocks
• Carbon steel construction provides suitable hardness for threading ferrous workpieces
• Metric equivalent thread size: M16

Compatibility

Designed for use with Collet 5 style die stocks and compatible with applications requiring a 5/8-11 UNC external thread standard.

Installation Notes

This die is installed into a matching Collet 5 die stock by a machinist or qualified maintenance technician. Secure the die firmly in the stock before engaging the workpiece, and apply appropriate cutting fluid to the die and workpiece to reduce heat buildup and extend tool life. Begin with a light pass and adjust the die incrementally to achieve the desired thread fit. Inspect finished threads with a thread gauge before placing the fastener or threaded component into service.
