Product Description
Milwaukee M5-0.90 mm Straight Flute Plug Tap
Model Number: 49-57-5128
The Milwaukee 49-57-5128 is an M5-0.90 mm Straight Flute Plug Tap, precision machined for creating or repairing clean, accurate internal threads. A tap cuts female threads into a drilled hole, and this plug tap is the most common general-purpose style, with a short tapered chamfer of a few threads at the tip that starts the tap square in the hole before it transitions to full-form threads, which makes it well suited to through-hole threading. The M5-0.90 mm designation identifies a 5 mm nominal diameter with a 0.90 mm thread pitch. Note the pitch carefully: Milwaukee offers the M5 tap in two pitches, this 0.90 mm version and the more common 0.80 mm coarse version, so match this tap to M5-0.90 mm hardware and confirm your thread pitch before ordering, since the two are not interchangeable. The M5-0.90 is a less common pitch used in specific applications, and the straight flute geometry gives the tap the versatility to handle general threading across common metals.
The tap is built for durability and lasting identification. High carbon steel construction holds a sharp cutting edge through the common metal applications it is designed for, and a protective black oxide coating resists corrosion while helping to reduce friction as the tap cuts. Milwaukee marks these taps with long-lasting laser-etched sizing rather than stamped markings, so the size and pitch stay clearly legible over the life of the tool, which matters when you carry both M5 pitches. The square shank is compatible with all standard tap handles and tap wrenches, so it drops right into the threading tools you already run.
This plug tap is designed for cutting threads in the most common metal applications, including brass, aluminum, mild steel, and more, which makes it a go-to for machinists, fabricators, and maintenance crews working with M5-0.90 mm hardware. It handles both tapping fresh holes and chasing or repairing an existing damaged M5-0.90 thread. For the cleanest finish, easiest cutting, and longest tap life, use the tap with cutting fluid to keep heat and friction down as it works.
