Eagle Cutting Tool CHD-5625-12-I Hex Rethread Die 9/16-12

Product Description

The EAGLE CUTTING TOOL CHD-5625-12-I is a 9/16-12 NC carbon hex rethread die designed to restore damaged or corroded external threads on fasteners, pipe fittings, and threaded rod. Built to the 9/16-inch diameter, 12 threads-per-inch Unified National Coarse (NC) standard, this import-grade die fits standard 1-inch hex die stocks and tap-and-die sets used across plumbing, HVAC, and general mechanical trades. It is the go-to tool when a bolt or fitting thread is too damaged to accept a nut or coupling but the fastener itself does not need full replacement.

This rethread die is suited for field repairs and shop use across residential and commercial applications. Plumbers, HVAC technicians, and general maintenance mechanics reach for it when they need to clean up corroded threads on 9/16-inch bolts, studs, or threaded fittings before reassembly. The NC thread form is one of the most common fastener standards in North American mechanical systems, making this die a practical addition to any service truck or shop toolbox.

Compatibility

Installation Notes

This die is installed and operated by a qualified tradesperson or mechanic using a standard hex die stock wrench. Before rethreading, clean the fastener or fitting of debris, rust, and old thread-locking compound. Apply cutting oil to the die and the work surface to reduce heat and extend die life. Do not attempt to cut full new threads with a rethread die — it is designed for cleanup and restoration of existing thread profiles only.
