Spiral Flute Tap: 7/16-14, UNC, 3 Flute, Semi-Bottoming, 2B & 3B Class of Fit, High Speed Steel, TiAlN Finish MPN:7557021

The spiral flute tap is designed to be used with through-hole machining processes where a clean hole with sharp edges is required. It features a 7/16-14 UNC thread size, ideal for applications such as woodworking, plastics, aluminum and general purpose metalworking. With its high-speed steel construction and TiAlN coating finish, it provides superior strength and resistance to wear, making it perfect for users looking for durability in their tapping processes. Its 3 flutes deliver optimal chip evacuation and minimize drastically debris accumulation on the tap's threads. The semi-bottoming design creates a good chip clearance allowing the user to achieve high cutting speeds, while the Class of fit indicates the quality of fit between the thread formed by the tap and the preformed hole it creates, resulting in superior thread performance. Therefore, this spiral flute tap is suitable for machinists, tool and die makers, engineers, maintenance personnel or anyone who requires precision and durability during tapping processes in industries like automotive, aerospace, electronics or any other metalworking industry.
