49-57-5168 Straight Flute Plug Tap, 9/16-18 Fine Thread, Hcs Black-oxide

The Milwaukee 49-57-5168 is a precision straight-flute plug tap designed for cutting 9/16-18 fine-thread internal threads in brass, aluminum, mild steel, and other common alloys. This tool is essential for fabrication, maintenance, repair work, and any application requiring accurate, consistent threading in through-holes. The fine-thread specification delivers the tight tolerances critical for precision assemblies and demanding metalworking tasks.

Crafted from high-speed steel (HCS) with a durable black-oxide coating, this tap resists corrosion, reduces friction during cutting, and maintains cutting-edge sharpness longer than standard carbon steel. The straight-flute design optimizes chip evacuation for a superior surface finish while minimizing torque and heat buildup. Laser-etched sizing marks provide permanent, legible identification for quick tool selection and reduced setup time, even after extensive use.

Features and Benefits
