Drillco 1-3/8"-8 Hex Die (335E224N)
Drillco 335E224N 1-3/8"-8 Hex Die is a precision hexagonal rethreading die crafted from high carbon steel and engineered to restore large coarse threads on bolts, rods, and similar components. Its extra-thick construction provides strength and stability for repairing damaged or jammed threads, while the staggered tooth geometry helps reduce chip buildup for smoother cutting action. This die is designed specifically for rethreading and is not intended to cut new threads on unthreaded bars, bolts, or pipes. The premium grade high-speed steel (HSS) cutting edges and bright finish improve tool life, reduce friction, and enhance cutting performance. Suitable for both through-hole and blind-hole applications, it works with standard square shank tap wrenches and is made in the USA for reliable quality.
