The hex dies feature long-lasting laser-etched sizing for the clearest markings and include a protective black oxide coating for corrosion resistance. The 1 in hex shape is compatible with the Milwaukee® Hex-Lok™ 2-in-1 threading handle, as well as all standard 1 in hex die stocks. Engineered for durability, our Milwaukee® 1 in hex dies are designed for cutting threads in the most common metal applications including brass, aluminum, mild steel, and more. For best results, use hex dies with cutting fluid. Milwaukee® 49-57-5336 Metric 1 in Hex Threading Die, M6 x 1.00 mm
