The Milwaukee 49-57-5189 is a straight flute plug tap designed for creating and repairing threads in through-holes and pipe fittings. This high-carbon steel (HCS) cutting tool features a four-flute geometry that optimizes chip evacuation during cutting, making it well-suited for threading work in brass, aluminum, and mild steel. The 3/4-inch overall length provides reach for standard industrial and fabrication applications, while the square shank design ensures compatibility with any standard tap handle or wrench.

Whether you're restoring equipment, repairing connections, or fabricating new components, this plug tap delivers consistent, accurate threads with minimal risk of cross-threading. Laser-etched size markings remain legible through repeated use, helping you identify the correct tool quickly and work with confidence.
