Description
Drillco 335E448N 3-3/4″-8 Hex Die is a precision hexagon rethreading die designed to restore damaged, worn, or jammed threads on bolts, studs, and threaded rods. Made from high carbon steel with premium grade high-speed steel (HSS) properties, this extra-thick die is intended for thread repair and not for cutting new threads on unthreaded bars, bolts, or pipes. The die features geometry suitable for both through-hole and blind-hole applications. A black oxide surface treatment improves wear resistance and extends tool life. The shorter screw machine length adds rigidity to reduce breakage during use. A round shank allows compatibility with various tap wrenches and die holders. Ideal for automotive, industrial, and maintenance applications where reliable thread restoration is required.
