The plug taps feature long-lasting laser-etched sizing for the clearest markings and include a protective black oxide coating for corrosion resistance. The square shank is compatible with all standard tap handles or tap wrenches and is designed for through-hole threading. Engineered for durability, our Milwaukee straight flute plug taps are designed for cutting threads in the most common metal applications including brass, aluminum, mild steel, and more.
