Milwaukee 1/4"-18 NPT Taper Tap

Milwaukee 1/4"-18 NPT Taper Tap

The 49-57-5191 Milwaukee 1/4"-18 NPT Taper Tap is a precision threading tool designed for clean, accurate pipe threads with a smooth, controlled start, especially in tougher materials. Built from durable high carbon steel and finished with a black oxide coating, it resists corrosion while maintaining long-term performance. The tapered design allows for a gradual thread engagement, making it easier to start threads straight—because fixing crooked threads is nobody’s idea of a good time.
