Drillco 3"-8 Hex Die (335E364N)
Drillco 335E364N 3"-8 Hex Die is a precision hexagonal rethreading die designed to repair large coarse threads on bolts, rods, and other threaded components. Manufactured from high carbon steel with premium grade high-speed steel (HSS) cutting edges, it provides excellent durability and reliable cutting performance for demanding thread repair applications. Its extra-thick construction offers strength and stability during rethreading, while the staggered tooth design minimizes chip buildup for smoother operation. This die is intended for rethreading damaged or jammed threads only and is not suitable for cutting new threads on unthreaded materials. Featuring a bright finish to improve lubricity and reduce friction, it fits standard square shank tap wrenches and works effectively in both through-hole and blind-hole repairs.
