Drillco 3-1/2″-8 Hex Die (335E432N)

Description

Drillco 335E432N 3-1/2-8 Hex Die is a precision-engineered hexagon rethreading die made from high carbon steel with premium grade HSS cutting edges for enhanced durability. Designed to restore damaged or jammed threads, this extra-thick die ensures reliable, long-lasting performance. It is not intended for cutting new threads on unthreaded bar, bolts, or pipes. The black oxide surface treatment provides improved wear resistance, while the self-centering 135° split-point reduces thrust requirements and minimizes walking during use. The shorter screw machine length adds rigidity, reducing breakage. Featuring a round shank compatible with standard holders, this USA-made die is ideal for mechanics and maintenance professionals requiring precise thread restoration tools.
