Milwaukee 1/8"-27 NPT Pipe Plug Tap

The Milwaukee 49-57-5189 1/8"-27 NPT Pipe Plug Tap is a precision threading tool built for clean, accurate results when creating or repairing pipe threads. Designed with a tapered profile for gradual thread cutting, it makes starting threads easier—especially in tougher materials. Constructed from high carbon steel with a corrosion-resistant black oxide finish, this tap is built to last and stay sharp, helping you get the job done right the first time (instead of re-threading… again).
