Eagle Cutting Tool CHD-13750-12-I Carbon Hex Rethread Die

Product Description

The EAGLE CUTTING TOOL CHD-13750-12-I is a carbon steel hex rethread die sized for 1-3/8 inch diameter threads at 12 threads per inch (TPI). Rethread dies are used to clean, restore, and chase damaged or corroded external threads on bolts, studs, rods, and pipe fittings without cutting new threads from scratch. The hex body profile allows a standard wrench or die stock to drive the tool with controlled torque. At 1.96 pounds, this is a solid, shop-grade tool suited for plumbing, mechanical, and general trade use where field thread repair is a routine task.

This rethread die is appropriate for restoring unified coarse and fine external threads in residential and commercial maintenance settings. Plumbers, pipefitters, and mechanical contractors use tools like this when salvaging threaded fasteners or fittings that have sustained thread damage from corrosion, impact, or cross-threading. The 1-3/8 inch by 12 TPI specification covers a range of heavy fastener and rod applications common in structural and mechanical installations.

Key Features

• 1-3/8 inch diameter, 12 TPI thread specification for restoring damaged external threads
• Hex body profile accepts standard wrenches and die stocks for controlled driving torque
• Carbon steel construction provides hardness suitable for threading ferrous and non-ferrous fasteners
• Rethread geometry chases and cleans existing threads rather than cutting new material aggressively
• Single-piece die at 1.96 pounds — substantial enough for heavy-duty trade use

Compatibility

Designed as an OEM-style replacement or direct sourcing option for hex rethread dies in the 1-3/8 inch by 12 TPI specification, suitable for use with standard die stocks and wrenches that accept hex body dies of this size.

Installation Notes

Thread restoration with a rethread die is typically performed by licensed plumbers, pipefitters, or mechanical technicians during maintenance and repair work. Before use, clean the damaged threads of debris, rust, and old thread sealant to ensure the die seats properly. Apply cutting oil to the die and the workpiece to reduce friction and extend tool life. Always advance the die in controlled increments and back off periodically to clear metal chips and prevent binding.
