Eagle Cutting Tool CHD-8750-14-I Carbon Hex Rethread Die

Product Description

The EAGLE CUTTING TOOL CHD-8750-14-I is a carbon hex rethread die designed to restore damaged or corroded external threads to their original specification. Sized for 7/8-14 NF (National Fine) thread, this hex-body die fits standard die stocks and hand wrenches, making it practical for field repairs and shop use alike. Weighing 1.96 pounds, it is a solid, duty-rated tool suited for mechanics, pipe fitters, HVAC technicians, and maintenance professionals who need to recover threaded fasteners and fittings rather than replace them outright.

This rethread die is used wherever 7/8-14 NF external threads appear on bolts, studs, pipe fittings, and threaded rod. Common applications include HVAC equipment repairs, plumbing and mechanical systems, and general industrial maintenance. The hex outer profile allows use with a standard open-end wrench or adjustable wrench in confined spaces where a full die stock cannot be used, making it well suited to in-place thread restoration on installed components.

Compatibility

Designed for use on 7/8-14 NF external threads. Fits standard hex die stocks and open-end wrenches sized for the die body. Suitable for rethreading steel and iron bolts, studs, and threaded fittings of matching thread specification.

Installation Notes

Thread restoration dies are typically used by mechanics, HVAC technicians, plumbers, and maintenance trades. Before use, clean the damaged thread area and apply cutting oil to reduce heat and extend die life. Start the die straight onto the fastener to avoid cross-threading, and advance in short increments, backing off periodically to clear chips. Always wear appropriate hand protection when operating cutting tools.
