The Milwaukee 49-57-5527 is a 2-piece high-speed steel plug tap and matching drill bit set engineered for cutting SAE National Fine (NF) threads. This compact set combines a tapered plug tap with a precision drill bit sized to create the proper pilot hole, streamlining thread-cutting work and reducing the need for multiple tools when preparing fastener holes in metal.
Whether you're performing automotive repairs, maintaining equipment, or completing custom metalworking projects, this set delivers reliable performance for standard American thread applications. The high-speed steel construction provides exceptional hardness and wear resistance, while the black oxide coating on the tap protects against rust and corrosion during storage and on the job site.
