Eagle Cutting Tool CHD-544-I Carbon Hex Rethread Die

Product Description

The EAGLE CUTTING TOOL CHD-544-I is a carbon hex rethread die sized for 5-44 unified fine thread fasteners. Hex-profile dies seat securely in a standard tap wrench or die stock, allowing technicians to chase and restore damaged or corroded external threads without replacing the fastener. The 5-44 designation indicates a 5 number size diameter with 44 threads per inch, a fine-pitch specification common in precision assemblies. At 1.96 pounds, the CHD-544-I is a solid, single-piece cutting tool suited for field or shop use by machinists, maintenance technicians, and trade professionals working with small-diameter threaded components.

This rethread die is used wherever 5-44 UNF external threads need to be cleaned, restored, or recut. Typical applications include precision instrument repair, small motor and appliance assembly, HVAC control component service, and electrical panel work where fine-thread fasteners secure terminal blocks or mounting hardware. It is equally useful in a shop environment for restoring threads on bolts and screws that have been cross-threaded or corroded.

Key Features

• 5-44 UNF thread specification for fine-pitch external thread restoration
• Hex profile body accepts standard die stocks and tap wrenches for controlled torque application
• Carbon steel construction provides adequate hardness for chasing threads on steel, brass, and aluminum fasteners
• Single-piece design with no adjustable components, providing consistent thread geometry on every pass
• Compact size suitable for field service kits and shop toolboxes

Compatibility

Designed as an OEM-style replacement-grade rethread die for use with standard hex die stocks sized to accept dies for number 5 diameter fasteners with 44 threads per inch UNF specification.

Installation Notes

Installation is performed by machinists or maintenance technicians using a properly sized hex die stock or adjustable wrench handle. Secure the die firmly in the stock before applying it to the fastener to prevent slipping and thread damage. Apply cutting oil or thread lubricant to the fastener before chasing threads to extend die life and improve cut quality. Always clean debris from the fastener after rethreading and inspect the restored thread with a mating nut before returning the assembly to service.
