Milwaukee 1/4-28 NF Hex Die

Milwaukee 1/4-28 NF Hex Die

The Milwaukee 49-57-5338 1/4"-28 NF Hex Die is a precision-machined threading tool built for clean, accurate external threads on fine-thread fasteners. Whether you're cutting new threads or restoring damaged ones, this die delivers consistent results with its high carbon steel construction and black oxide coating for durability and corrosion resistance. With laser-etched markings and a clearly labeled starting side, it helps you get properly aligned from the start—because fixing a crooked thread later is a lot more work than doing it right the first time.
