49-57-5169 5/8-11 Coarse Thread Straight Flute Plug Tap, Hcs

The Milwaukee 49-57-5169 is a 5/8-11 coarse-thread straight flute plug tap designed for cutting precise internal threads in metalworking, fabrication, and repair applications. This high-carbon steel (HCS) tap is engineered to produce clean, accurate threads in both ferrous and non-ferrous metals, making it an essential tool for professional machinists, contractors, and DIY enthusiasts who demand reliable performance and consistent results.

The straight flute geometry reduces torque and minimizes chip buildup during operation, enabling smooth cutting even in deep holes. This design also decreases chatter and vibration, which translates to faster setup times, fewer errors, and a superior thread finish. The black oxide coating provides corrosion resistance and extends tool life in demanding shop environments, while laser-etched sizing markings offer instant size identification to streamline your workflow and eliminate guesswork.
