1/2-12 Left Hand Tap And Die Set – High Speed Steel Threading Kit For Left-Hand Bolts, Includes Plug Tap And Round Die (1/2" X 12 TPI)

About This Product

If you're working with left-hand threaded bolts or need to create reverse threads for specialized machinery, this tap and die set is exactly what you need.

It includes a 1/2-12 left hand plug tap and a matching round die—both made from high-speed steel (HSS) that stays sharp even when cutting through tough alloys, carbon steel, or cast iron.

The 12 threads per inch pitch is precision-ground to standard specs, so it'll match existing 1/2-12 LH hardware perfectly.

The plug tap design makes it easy to start threads in through-holes or deeper bores, and the die fits standard die stocks for smooth, clean external threading.

This set is a lifesaver for automotive repairs, industrial maintenance, or any project that calls for reverse-thread rods or fasteners.

Chip removal is efficient, so you get a clean finish without clogging.

Solid, reliable, and built to last.
