Milwaukee 1/8"-27 NPT Hex Die

Milwaukee 1/8"-27 NPT Hex Die

The Milwaukee 49-57-5389 1/8"-27 NPT Hex Die is a precision threading tool built for clean, accurate external threads—whether you’re cutting new ones or rescuing old ones that have seen better days. Made from high carbon steel with a black oxide finish, it’s designed for durability and corrosion resistance, while clear laser-etched markings and a labeled starting side help you get lined up correctly the first time (because cross-threading is a mistake you only want to make once).
