Machinists and metalworkers, these BestParts carbide drill mills are serious tools for tough jobs! You get two identical tools in the package, both featuring 5/16\ cutting diameter, 5/16\ shank, 13/16\ length of cut, and 2-1/2\ overall length.
The 4-flute design with 90° included angle makes these perfect for general purpose milling in steel, brass, iron, and non-ferrous materials. The AlTiN coating is the real star - it significantly improves performance and tool life, especially in harder materials or high-temperature applications.
Made from solid carbide, these tools can run at higher speeds than high-speed or cobalt steel while resisting wear and heat buildup. They're precision ground for accuracy and consistency, so you get clean cuts and reliable performance every time.
Whether you're working in a professional shop or serious home workshop, these drill mills deliver professional-grade results. The two-pack means you've got a backup ready when needed, saving you downtime on important projects.
