Milwaukee M8-1.25 mm Plug Tap

The Milwaukee 49-57-5143 M8-1.25 mm Plug Tap is a precision-machined hand tap designed for creating new threads or repairing damaged threads in a variety of metal materials. Manufactured from high carbon steel with a black oxide finish for enhanced corrosion resistance, this plug-style tap is ideal for threading through holes in materials such as brass, aluminum, and mild steel. Its straight flute design provides reliable chip evacuation for common threading applications, while durable laser-etched markings make identification quick and easy.
