Eagle Cutting Tool CHD-11250-12-I Carbon Hex Rethread Die

Product Description

The EAGLE CUTTING TOOL CHD-11250-12-I is a carbon hex rethread die designed to restore damaged or corroded external threads to their original specification. Built for 1-1/8 inch diameter fasteners with a 12-thread-per-inch National Fine (NF) pitch, this die cleans up and re-forms thread profiles without requiring full material removal. The hex outer body accepts a standard tap wrench or die stock for controlled hand operation. It is a common tool in mechanical, plumbing, and HVAC service work wherever threaded fasteners are refurbished in the field.

This rethread die is suited for field repair and shop use on 1-1/8 inch-12 NF threaded rods, bolts, and fittings. It is appropriate for use on steel and other ferrous fasteners found in structural, mechanical, and fluid-system assemblies. Service technicians and mechanical contractors use rethread dies to salvage hardware that would otherwise require full replacement, reducing downtime on equipment repairs.

Installation Notes

A licensed mechanic or experienced tradesperson should operate this die using a properly sized die stock to maintain alignment and avoid cross-threading. Apply cutting oil or thread-cutting fluid before and during use to reduce heat and extend die life. Ensure the fastener or workpiece is secured before beginning thread restoration. Inspect the restored threads with a matching nut or thread gauge after use to confirm proper fit.
