Drillco 3-1/4"-12 Hex Die (335E416F)
Drillco 335E416F 3-1/4"-12 Hex Die is a precision-engineered hexagonal rethreading die designed to restore damaged or jammed threads with accuracy and durability. Made from high carbon steel with premium grade high-speed steel (HSS) cutting geometry, this extra-thick die provides long-lasting performance in demanding applications. It features a self-centering 135° split-point to reduce thrust and minimize walking, improving 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 exclusively for rethreading—not for cutting new threads on unthreaded bars, bolts, or pipes—this die includes a round shank for stability and fits both through-hole and blind-hole applications. Made in the USA, it is ideal for professionals seeking dependable thread repair tools.
