Straight Flute Tap #0-80 UNF, 2 Flutes, Plug, 2B Class of Fit, High Speed Steel, TiN Coated is designed for precise machining and tooling applications that require an UNC thread form. The two flutes provide faster chip removal while the plug chamfer at the cutting end eases starting. Manufactured from high-speed steel with a Rockwell hardness of 58-62HRC, it offers strength and durability for consistently reliable performance in various materials such as cast iron or soft steels. Furthermore, the TiN coating on the tap minimizes friction, ensuring smoother operation while increasing the tool's life significantly. With an overall length of 4-1/8 and diameter of 1/2, it is suitable for tapping holes up to a depth of 3 times its diameter with ease, making it ideal for machinists, mechanics, and engineers alike.
