Milwaukee 17PC SAE Tap and Die Set includes precision machined threading accessories and threading handles designed for the most common applications. The taps and dies feature long-lasting laser-etched sizing for clear markings and come with a protective Black Oxide coating to resist corrosion. The plug taps have a square shank compatible with all standard tap handles or tap wrenches and are designed for through-hole threading. The hex dies have a 1” hex shape that works with the MILWAUKEE® Hex-LOK™ 2-in-1 Handle (sold separately) as well as all standard 1” Hex Die stocks. This set also includes drill bits for pilot drilling, optimized for use with drill drivers. These taps and dies are for cutting threads in common metals such as brass, aluminum, and mild steel. For results, use with cutting fluid to ensure smooth and precise threading. Model Number: 49-22-5600
