Product Description
Milwaukee 12-24 NC Straight Flute Plug Tap
Model Number: 49-57-5130
The Milwaukee 49-57-5130 is a 12-24 NC 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 a natural fit for through-hole threading. The 12-24 NC designation identifies a number 12 machine screw diameter with 24 threads per inch in the National Coarse series. The number 12 is the largest of the numbered machine-screw sizes before threads move into fractional-inch diameters, and 12-24 turns up in electrical, HVAC and sheet metal, rack and enclosure hardware, and general assembly where a strong, larger machine-screw connection is needed. The straight flute geometry gives the tap the versatility to handle general threading work 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 stays clearly legible over the life of the tool. 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 electricians, HVAC and sheet metal techs, machinists, fabricators, and maintenance crews who work with 12-24 hardware. It handles both tapping fresh holes and chasing or repairing an existing damaged 12-24 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.
