Drillco 4"-8 Hex Die (335E464N)
Drillco 335E464N 4"-8 Hex Die is a precision-engineered hexagonal rethreading die designed to restore damaged or jammed threads with durability and accuracy. Crafted from high carbon steel with premium grade high-speed steel (HSS) cutting geometry, this extra-thick die provides extended tool life and reliable performance. It features a self-centering 135° split-point to reduce thrust and minimize walking, enhancing cutting precision. The black oxide surface treatment improves corrosion resistance and wear protection. Its shorter screw machine length adds rigidity, reducing breakage during use. Intended exclusively for rethreading—not for cutting new threads on unthreaded bars, bolts, or pipes—this die has a round shank suitable for both through-hole and blind-hole applications. Made in the USA, it is ideal for professionals requiring dependable thread repair tools.
