49-57-5157 7/16-20 Fine Thread Straight-flute Plug Tap, Hcs

The Milwaukee 49-57-5157 is a straight-flute plug tap designed for creating precise internal threads in through-holes. This hand tool cuts clean, accurate threads in brass, aluminum, mild steel, and other common alloys, making it essential for metalworking, maintenance, and repair tasks where tight tolerances matter. The straight-flute geometry evacuates chips efficiently and delivers consistent thread profiles, reducing rework and extending component life.

The square shank fits any standard tap holder for quick setup and seamless integration into your existing workshop tools. Whether you're installing new fasteners, repairing stripped threads, or working on precision assemblies, this tap delivers the accuracy professionals demand.
