Milwaukee Tool 49-57-5190 Bsp Pipe Tap Straight Flute

Product Description

The MILWAUKEE TOOL 49-57-5190 is a straight-flute British Standard Pipe tap designed for cutting G(BSP) internal threads in metalwork applications. Built from high-carbon steel with a black oxide coating, this tap delivers reliable thread formation in a compact 2.25-inch overall length. The plug chamfer style provides a balanced lead-in, making it well suited for through-hole tapping operations where a moderate starting taper is needed. With four flutes and a right-hand thread direction, it handles standard pipe thread cutting tasks in shop and field environments. Licensed plumbers and pipefitters are the primary users of this tool.

This tap is used when cutting G(BSP) parallel pipe threads into fittings, manifolds, valves, or pipe bodies that follow British Standard Pipe specifications. It is appropriate for residential and light commercial plumbing and mechanical applications where BSP-threaded connections are specified. The 0.375-inch shank diameter and 0.375-inch thread length make it a compact, purpose-built tool for tapping shallow pipe thread entries in tight access areas or standard bench work.

Installation Notes

This tap is typically used by licensed plumbers, pipefitters, and machinists performing thread cutting operations in metal workpieces. Always secure the workpiece firmly before tapping and use appropriate cutting fluid to extend tap life and improve thread quality. Back the tap out periodically to clear chips and prevent breakage. Follow applicable trade codes and manufacturer guidelines for thread depth and hole preparation.
