Spiral Point Tap: #5-40 UNC, 2 Flutes, Plug Chamfer, 2B/3B Class of Fit, High-Speed Steel, Nitride MPN:TT91020NS

The #5-40 UNC high-speed steel spiral point tap is ideal for machinists or engineers requiring precision cutting threads into soft materials such as aluminum, brass or mild steels; while maintaining a class of fit (2B/3B) providing minimal chips to minimize build-up during the threading process. The spiral point design delivers faster and smoother cutting, and a plug chamfer ensures precise starting of threads with reduced breaking when entering or cutting through different material compositions while minimizing tool wear. Spiral point taps such as this 2 flute 5-40 UNC tap by Helios are versatile for machining and creating internal threads into small diameter or blind holes; fitting in Machining and Tooling industries' requirements where accuracy and efficiency is essential to produce precise and well-fitted parts.
