The EAGLE CUTTING TOOL CHD-40000-4-I is a carbon hex rethread die designed to restore damaged or corroded external threads. Built for field and shop use, this die handles large-diameter thread repair at 4 inches with a 4 TPI (threads per inch) pitch. The hexagonal body allows standard wrench engagement for controlled torque application without a dedicated die stock. Plumbers, pipefitters, and mechanical contractors reach for this tool when bolt or pipe threads are too damaged to accept a nut or fitting but the fastener or pipe itself is still serviceable.
This rethread die is suited for heavy-duty applications where large-diameter external threads need to be chased or restored on pipe, rod, or fastener stock. The 4-inch diameter and 4 TPI specification place it in the range of large pipe and industrial threaded components common in commercial plumbing, mechanical, and industrial maintenance work. It is a single-piece tool requiring no special holder, making it practical for on-site repair without extensive tooling setup.
Designed for restoring or chasing 4-inch external threads at 4 TPI on pipe, rod, or threaded fastener stock in commercial plumbing and industrial maintenance applications.
Thread chasing and rethread work should be performed by qualified tradespeople familiar with thread standards and cutting tool safety. Ensure the workpiece is secured before applying the die, and use appropriate cutting fluid to reduce friction and extend die life. Inspect the die for wear or chipping before each use, and never force a die onto severely deformed threads without first cleaning and dressing the thread lead-in.
