Drillco 3-1/2"-4 Hex Die (335E432C)
Drillco 335E432C 3-1/2"-4 Hex Die is a precision hexagon rethreading die designed to restore damaged, worn, or jammed threads on bolts, studs, and threaded rods. Manufactured from high carbon steel with premium grade high-speed steel (HSS) properties, this extra-thick die is specifically intended for thread repair, not for cutting new threads on unthreaded bars, bolts, or pipes. It features geometry suitable for through-hole and blind-hole applications. The black oxide surface treatment enhances durability and extends tool life, while the shorter screw machine length adds rigidity to reduce breakage during use. A round shank ensures compatibility with various tap wrenches and die holders. This die is ideal for industrial, automotive, and maintenance uses where reliable thread restoration is needed.
