Drillco 3-1/2"-12 Hex Die (335E432F)
Drillco 335E432F 3-1/2"-12 Hex Die is a precision hexagonal rethreading die engineered to restore large fine threads on bolts, rods, and similar components. Made from high carbon steel with premium grade high-speed steel (HSS) cutting edges, it provides excellent durability and cutting performance in demanding thread repair applications. The extra-thick construction offers strength and stability during rethreading, while the staggered tooth design minimizes chip buildup for smoother operation. This die is designed for rethreading damaged or jammed threads only and is not intended for cutting new threads on unthreaded materials. Featuring a bright finish to reduce friction and enhance lubricity, it fits standard square shank tap wrenches and works effectively in both through-hole and blind-hole repairs.
