Eagle Cutting Tool CHD-6250-18-I 5/8-18 Nf Carbon Hex Rethread Die

Product Description

The EAGLE CUTTING TOOL CHD-6250-18-I is a carbon steel hex rethread die designed to restore damaged or corroded external threads on fasteners and threaded rod. Sized for 5/8-18 NF (National Fine) thread specification, this die fits standard hex die stocks and hand wrenches used in the field and shop. It is a practical tool for maintenance, repair, and overhaul work where chasing or restoring threads on existing hardware is faster and more economical than replacing the fastener. Plumbers, pipefitters, electricians, and general mechanical tradespeople keep rethread dies on hand for fast thread repair on bolts, studs, and fittings.

This rethread die is suited for shop benches, service trucks, and job-site tool kits wherever 5/8-18 NF threads need to be cleaned up or restored. Common applications include thread repair on mounting hardware, equipment frames, and mechanical assemblies where fine-thread fasteners are standard. The hex outer profile allows use with a standard adjustable wrench or ratchet-style die stock for controlled hand cutting.

Installation Notes

Thread repair dies are typically used by mechanical tradespeople following standard shop or field practices. Before chasing threads, clean debris and corrosion from the fastener and apply cutting oil to reduce heat and extend die life. Secure the workpiece or ensure the fastener is accessible before applying the die. Follow applicable facility safety procedures when working with cutting tools on energized or pressurized systems.
