49-57-5154 M10x1 Straight Flute Plug Tap, 4-flute Hcs, Black-oxide

The Milwaukee 49-57-5154 is a high-precision straight flute plug tap designed to cut clean internal threads in a single pass. Built from high carbon steel (HCS) with a black-oxide finish, this M10×1 metric tap delivers reliable performance in brass, aluminum, and mild steel. The compact 31.75 mm overall length and four-flute geometry work together to minimize torque, reduce chip binding, and produce smooth, consistent thread profiles—essential for both new fabrication and equipment repair.

This Milwaukee plug tap produces consistent thread profiles in demanding metalworking environments, extending tool life and reducing rework. The black-oxide coating provides superior corrosion resistance, keeping the tap ready for use through extended storage. Its square shank fits all standard tap handles and wrenches, providing a secure grip for straightforward operation without special equipment.

Features and Benefits
