Drillco 1-1/4"-8 Hex Die (335E216N)
Drillco 335E216N 1-1/4"-8 Hex Die is a precision-engineered hexagonal rethreading die designed to restore damaged or jammed threads quickly and accurately. Manufactured from high carbon steel with premium grade high-speed steel (HSS) cutting geometry, this tool features an extra-thick body for stability during rethreading operations. Its staggered tooth design minimizes chip buildup for smoother performance, while the bright finish enhances lubricity and corrosion resistance. Suitable for both through-hole and blind-hole applications, the die 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 dependable choice for mechanics, maintenance professionals, and metalworkers.
