Eagle Cutting Tool CHD-35000-8-I Carbon Hex Rethread Die

Product Description

The EAGLE CUTTING TOOL CHD-35000-8-I is a carbon hex rethread die designed to restore damaged or corroded external threads on fasteners, pipe fittings, studs, and threaded rod. Sized for 3-1/2 inch diameter threads at 8 threads per inch (TPI), this die is held in a standard hex die stock for manual operation. It is a practical tool for maintenance and repair work across plumbing, mechanical, and general industrial applications where full thread replacement or re-cutting is needed without removing the fastener from service.

This rethread die is suited for job-site repair and shop maintenance tasks where larger-diameter threaded components have sustained thread damage from corrosion, impact, or misalignment. The hex body allows secure seating in a compatible die stock or wrench. Typical users include pipefitters, millwrights, maintenance technicians, and plumbers working on heavy equipment, pipe connections, or structural fasteners requiring 3-1/2 inch, 8 TPI thread profiles.

Key Features

• 3-1/2 inch diameter, 8 TPI thread specification for large-diameter rethread applications
• Hex body design seats securely in standard hex die stocks for controlled manual operation
• Carbon steel construction provides adequate hardness for restoring threads on common fastener and pipe materials
• Rethread geometry cleans and restores existing thread profiles without full re-cutting in most cases
• Minimum order quantity of 1 unit — available as a single die

Compatibility

Designed as an OEM-style replacement or equivalent hex rethread die for use in standard hex die stocks accommodating 3-1/2 inch dies. Intended for use on external threads conforming to 3-1/2 inch, 8 TPI thread standards.

Installation Notes

This die is installed and operated by a qualified tradesperson using a properly sized hex die stock. Ensure the die is fully and squarely seated in the die stock before applying torque to avoid die damage or cross-threading. Apply appropriate cutting oil to the threads and die during operation to reduce friction and extend die life. Always wear appropriate hand and eye protection when performing thread restoration work.
