Eagle Cutting Tool CHD-11250-8-I Hex Rethread Die 1-1/8 8 Tpi

Product Description

The EAGLE CUTTING TOOL CHD-11250-8-I is a carbon steel hex rethread die designed to restore damaged or corroded external threads on fasteners, pipe fittings, and threaded rod. It cuts a 1-1/8 inch nominal diameter thread at 8 threads per inch (TPI), conforming to standard UNC coarse-thread specification. The hex body profile accepts a standard die wrench or adjustable wrench, making field use straightforward. This die is suited for maintenance, repair, and overhaul work where restoring thread integrity is faster than replacing the fastener. Plumbers, pipefitters, millwrights, and general maintenance technicians are the primary users.

This rethread die is used in industrial, commercial, and residential maintenance settings wherever 1-1/8 inch 8 TPI external threads need cleaning up or restoration. Common applications include threaded rod repair, bolt and stud reconditioning, and pipe fitting thread cleanup. The hex form factor fits standard die stocks and adjustable wrenches without requiring a round die holder, which is an advantage in tight spaces or field repair situations.

Key Features

• 1-1/8 inch diameter, 8 TPI UNC coarse-thread profile for standard fastener compatibility
• Hex body design accepts standard die wrenches and adjustable wrenches without a dedicated die stock
• Carbon steel construction provides adequate hardness for rethreading mild steel, iron, and softer alloy fasteners
• Compact single-tool format suited for field repair and maintenance kits
• Restores damaged, corroded, or paint-fouled external threads without full fastener replacement

Compatibility

Designed for use on 1-1/8 inch 8 TPI UNC externally threaded fasteners, bolts, studs, and threaded rod in standard coarse-thread applications.

Installation Notes

Thread restoration dies are typically used by maintenance mechanics, pipefitters, and millwrights. Before use, ensure the fastener or rod is secured and free of burrs that could cause the die to misalign on entry. Apply cutting oil to the die and workpiece to improve cut quality and extend die life. Do not force the die onto severely deformed threads in a single pass; back off periodically to clear chips and prevent die breakage.
