Eagle Cutting Tool CHD-17500-8-I Carbon Hex Rethread Die

Product Description

The EAGLE CUTTING TOOL CHD-17500-8-I is a carbon hex rethread die designed to restore damaged or corroded external threads on fasteners, pipe fittings, and threaded rod. Built in a standard hex profile for use with a die stock or wrench, this die cuts a 1-3/4 inch diameter thread at 8 threads per inch (TPI). It is a go-to tool for maintenance technicians, plumbers, pipefitters, and industrial mechanics who need to chase or restore large-diameter coarse threads in the field or shop without replacing the entire fastener or fitting.

This rethread die is suited for heavy-duty maintenance and repair work across industrial, commercial, and mechanical trade environments. Typical applications include restoring thread integrity on large bolts, threaded rod, and pipe fittings where corrosion, impact damage, or cross-threading has compromised the thread profile. At 1-3/4 inch by 8 TPI, this is a large-diameter coarse-thread die most commonly encountered in structural, piping, and heavy equipment applications. Import-grade construction makes it a practical choice for lower-frequency use or as a backup die in a shop set.

Key Features

• 1-3/4 inch diameter, 8 TPI thread specification for large coarse-thread restoration
• Hex body profile accepts standard die stocks and adjustable wrenches for controlled torque application
• Carbon steel construction provides sufficient hardness for chasing and restoring threads on mild steel, iron, and similar materials
• Compact and portable for field repair use
• Minimum order quantity of 1 unit for single-piece purchasing flexibility

Compatibility

Designed for use with standard hex die stocks sized to accept a 1-3/4 inch hex rethread die. Suitable for chasing unified coarse (UNC) threads on mild steel fasteners, threaded rod, and fittings of matching thread specification.

Installation Notes

This die is installed by a mechanic, pipefitter, or maintenance technician using a compatible hex die stock. Before use, ensure the workpiece is secured and free of burrs or heavy debris that could damage the die. Apply a suitable cutting oil to the threads and die before starting to reduce friction and extend die life. Never force the die onto a severely damaged thread without first dressing the lead end of the fastener with a file.
