Drillco 1-7/8"-8 Hex Die (335E256N)
Drillco 335E256N 1-7/8"-8 Hex Die is a precision-engineered hexagonal rethreading die designed to restore damaged or jammed threads efficiently and accurately. Made from high carbon steel with premium grade high-speed steel (HSS) cutting geometry, this die offers durability, stability, and consistent performance in demanding thread repair applications. The extra-thick construction ensures rigidity during rethreading, while the bright finish enhances lubricity and resists corrosion. Suitable for both through-hole and blind-hole applications, it is intended solely for rethreading existing threads—not for cutting new threads on unthreaded bars, bolts, or pipes. The square shank fits standard tap wrenches, making it a reliable tool for mechanics, maintenance personnel, and metalworkers.
