Drillco 4″-4 Hex Die (335E464C)

Description

Drillco 335E464C 4″-4 Hex Die is a precision hexagonal rethreading die designed to repair large coarse threads on bolts, rods, and similar fasteners. Made from high carbon steel with premium grade high-speed steel (HSS) cutting edges, it provides excellent durability and reliable cutting performance for heavy-duty thread repair applications. The extra-thick body offers strength and stability during rethreading, while the staggered tooth design helps minimize chip buildup for smoother cutting. This die is intended for rethreading damaged or jammed threads only and is not suitable for cutting new threads on unthreaded materials. It features a bright finish that reduces friction and enhances lubricity, and fits standard square shank tap wrenches for use in both through-hole and blind-hole repairs.
