Description

Drillco 335E316F 2-1/4″-12 Hex Die is a precision hex rethreading die engineered to restore damaged or jammed threads reliably and accurately. Manufactured from high carbon steel with premium grade high-speed steel (HSS) cutting geometry, this extra-thick die provides the rigidity needed for effective thread repair while resisting wear. Designed specifically for rethreading—not for cutting new threads on unthreaded bars, bolts, or pipes—the tool performs well in both through-hole and blind-hole applications and fits standard tap wrench tooling via its square shank. Ideal for mechanics, maintenance technicians, and metalworkers who require a durable 2-1/4″-12 die for thread restoration, it delivers consistent results while minimizing workpiece damage.
