Eagle Cutting Tool CHD-6875-11-I Carbon Hex Rethread Die

Product Description

The EAGLE CUTTING TOOL CHD-6875-11-I is a carbon steel hex rethread die designed to restore damaged or corroded external threads to their original specification. Built in an 11/16-inch, 11 TPI National Coarse (NC) imperial thread profile, this die fits standard hex die stocks and tap wrenches used by plumbers, pipefitters, HVAC techs, and maintenance mechanics. The hex body allows secure grip in a die stock or adjustable wrench for controlled cutting torque. It is a practical shop and field tool for cleaning up fastener threads, bolt ends, and threaded rod without full replacement of the fastener.

This rethread die is suited for repair work on 11/16-11 NC imperial threaded fasteners found in mechanical, plumbing, and HVAC equipment installations. Typical applications include restoring threads on bolts, studs, and threaded rod ends damaged by rust, impact, or cross-threading. It is appropriate for both shop bench work and field service where a full thread cutting setup is not practical. The single-piece hex body construction keeps the tool compact and easy to transport in a service bag or tool kit.

Key Features

• 11/16 in - 11 NC imperial thread profile for standard coarse-thread fastener repair
• Carbon steel construction provides adequate hardness for restoring threads on mild steel and iron fasteners
• Hex body design accepts standard die stocks and adjustable wrenches for controlled torque application
• Rethread geometry cleans and restores existing threads rather than cutting new ones from solid stock
• Compact single-piece form suits field service toolkits and shop inventory

Compatibility

Designed for use on 11/16-11 NC imperial external threads. Fits standard hex die stocks sized for this thread family. Intended for rethread and thread-chasing applications on mild steel, iron, and similar ferrous fasteners.

Installation Notes

This tool is used by plumbers, pipefitters, HVAC technicians, and general maintenance mechanics. Before chasing threads on installed equipment, de-energize electrical sources and relieve any pressure in the associated system per applicable safety codes. Secure the workpiece firmly before applying the die to prevent movement and cross-threading. Apply cutting oil to the die and workpiece threads to reduce friction and extend tool life.
