Eagle Cutting Tool CHD-16250-55-I Carbon Hex Rethread Die

Product Description

The EAGLE CUTTING TOOL CHD-16250-55-I is a carbon steel hex rethread die designed to restore damaged or corroded external threads on imperial fasteners and pipe fittings. This die measures 1-5/8 inches across and cuts at 5-1/2 threads per inch, making it suited for heavy-duty rethread work on larger-diameter bolts, studs, and threaded rod. The hex body allows standard wrench engagement for controlled torque during use. Plumbers, pipefitters, and mechanical contractors reach for this type of die when field repairs require restoring thread integrity without full fastener replacement.

This rethread die is intended for use on imperial-thread fasteners and fittings in residential and commercial mechanical systems. Typical applications include repairing damaged external threads on large bolts, pipe nipples, and structural hardware encountered during HVAC, plumbing, and general mechanical service work. It is well suited for shop use or field repair kits where restoring coarse-pitch threads on oversized fasteners is a recurring task.

Compatibility

Designed for use on imperial external threads with a 1-5/8 inch diameter and 5-1/2 threads per inch pitch, compatible with standard hex die stocks that accept this body size.

Installation Notes

This die is installed and operated by plumbers, pipefitters, or mechanical technicians performing thread restoration. Ensure the fastener or fitting is secured in a vise before engaging the die to prevent movement during cutting. Apply cutting oil to the threads and die before use to extend die life and produce a cleaner thread profile. Inspect the die for wear or chipping before each use and replace if cutting performance degrades.
