Drillco 3-1/4″-4 Hex Die (335E416C)

Description

Drillco 335E416C 3-1/4-4 Hex Die is a precision-engineered hexagon rethreading die made from high carbon steel with premium grade HSS cutting edges for durability and extended tool life. Designed for restoring damaged or jammed threads, this extra-thick die is not intended for cutting new threads on unthreaded bar, bolts, or pipes. It features a black oxide surface treatment to improve wear resistance, and a self-centering 135° split-point that reduces thrust requirements and minimizes walking during use. The shorter screw machine length adds rigidity to reduce breakage. With a round shank compatible with standard holders, this USA-made die offers dependable performance for mechanics and maintenance professionals.
