Drillco 2-7/8"-8 Hex Die (335E356N)
Drillco 335E356N 2-7/8"-8 Hex Die is a precision-engineered hexagonal rethreading die designed to restore damaged or jammed threads with reliability and accuracy. Constructed from high carbon steel with premium grade high-speed steel (HSS) cutting geometry, this extra-thick die ensures long-lasting durability. Featuring a self-centering 135° split-point to reduce thrust and minimize walking, it improves ease of use and precision. The black oxide surface treatment enhances tool life by resisting corrosion and wear. Its shorter screw machine length adds rigidity to reduce breakage during operation. Designed for rethreading only—not for cutting new threads on unthreaded bars, bolts, or pipes—this die features a round shank for stability and is suitable for both through-hole and blind-hole applications. Made in the USA, it is ideal for professionals needing dependable thread repair tools.
