49-57-5538 Nf Plug Tap & Drill Bit Set, High-carbon Steel, 2-piece

The Milwaukee 49-57-5538 is a 2-piece NF plug tap and drill bit set designed for thread cutting and drilling in metalworking, automotive repair, machinery maintenance, and industrial applications. This kit combines a plug tap and drill bit, both made from high-carbon steel for durability and wear resistance. The set is engineered for SAE thread standards with a National Fine (NF) thread form, which produces finer-pitch threads for secure fastener engagements in high-stress applications.

The set provides a matched pair of tools in a compact format that is easy to organize and transport on the job site or workshop. The carded packaging keeps the tools protected during storage and deployment.
