Our MILWAUKEE 1-Inch Hex Threading Dies are precision machined for creating or repairing clean, accurate (external) threads. 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 Hex shape is compatible with the MILWAUKEE Hex-LOK 2-in-1 Threading Handle, as well as all standard 1 Hex Die stocks. Engineered for durability, our MILWAUKEE 1-Inch 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.
