Eagle Cutting Tool CHD-5625-18-I Hex Rethread Die 9/16 18NC

Product Description

The EAGLE CUTTING TOOL CHD-5625-18-I is a carbon hex rethread die designed to restore damaged or worn external threads on fasteners, bolts, and threaded rod. Sized for 9/16 inch diameter stock with an 18 threads-per-inch National Coarse (NC) thread form, this hex-body die fits standard die stocks and ratchet-style die holders. It is a practical shop and field tool for machinists, pipefitters, maintenance mechanics, and general trade professionals who need to clean or re-cut threads without full replacement of the fastener. The hex profile allows wrench-driven operation when a die stock is not available.

This rethread die is suited for use in maintenance, repair, and operations (MRO) settings, fabrication shops, and field service work where fastener threads have been damaged by corrosion, impact, or cross-threading. The 9/16-18 NC size covers a common fastener dimension found in general mechanical assemblies, structural connections, and equipment frames. It is typically used by maintenance technicians and trade professionals performing bolt and hardware repair on carbon steel fasteners.

Key Features

• 9/16 inch diameter, 18 TPI National Coarse thread form for restoring damaged external threads
• Hex body profile allows wrench-driven use or standard die stock operation
• Carbon steel construction suitable for threading and rethreading carbon steel fasteners
• Minimum order quantity of 1, available as a single unit for spot repair needs

Compatibility

Designed as an OEM-style replacement and standard-fit rethread die for use with 9/16 inch-18 NC threaded fasteners in die stocks and ratchet die holders that accept hex-body dies.

Installation Notes

Rethread dies are installed and operated by machinists, mechanics, and trade professionals using a die stock, ratchet holder, or open-end wrench on the hex body. Apply cutting oil to the die and fastener before use to reduce heat and extend die life. Ensure the die is started square to the fastener axis to avoid cross-threading. Follow applicable shop safety practices when working with cutting tools.
