Made from high-speed steel for durability, the tap has an H3 hardness rating, enhancing its ability to stand up against wear over time, while also having a bright/uncoated finish which helps prevent galling on threads, giving it extra longevity and consistent performance. The tap is well-suited for applications in the automotive and metalworking industries as well as general machine shops where creating precise and clear threads is essential. With its spiral point design that provides a smooth and efficient tapping experience, professionals can easily achieve accurate threading even in hard materials such as stainless steel or aluminum with minimal effort and time-consuming manual labor.
