Drillco 1-5/8"-12 Hex Die (335E240F)
Drillco 335E240F 1-5/8"-12 Hex Die is a precision hexagonal rethreading die designed to repair large fine threads on bolts, rods, and similar components. Made from high carbon steel with premium grade high-speed steel (HSS) cutting edges, it delivers strength, durability, and consistent performance in demanding repair applications. Its extra-thick body increases stability during use, while the staggered tooth design reduces chip buildup for smoother cutting action. This die is intended for rethreading only and should not be used to cut new threads on unthreaded materials. Featuring a bright finish to improve lubricity and reduce friction, it works with standard square shank tap wrenches and is suitable for both through-hole and blind-hole applications.
