Drillco 45mm x 4.5 Carbon Hex Re-Thread Die (336E450B)
Drillco 336E450B 45mm x 4.5 Carbon Hex Re-Thread Die is a precision hexagonal rethreading die engineered to restore damaged or jammed metric threads with excellent durability and accuracy. Constructed from high carbon steel with general purpose high-speed steel (HSS), this die features a self-centering 135° split-point that reduces thrust and minimizes walking, ensuring precise and easy cutting. The black oxide surface treatment enhances tool life by improving corrosion resistance and reducing wear. Its shorter screw machine length adds rigidity to reduce the risk of breakage. Specifically designed for rethreading damaged threads—not for cutting new threads on unthreaded bars, bolts, or pipes—this die has a round shank compatible with standard tap wrenches and is suitable for both through-hole and blind-hole applications. Made in the USA, it meets professional standards for thread repair.
