The Ruko-246080UNF tap set is designed for creating through and blind hole threads in a variety of materials, including unalloyed and low-alloy steels with a tensile strength of up to 800 N/mm², as well as malleable cast iron and non-ferrous metals. This set allows for an efficient threading process, as the thread is cut in two steps, guaranteeing a precise and high-quality finish. The set includes two pieces: a roughing tap and a finishing tap, facilitating the creation of a fine thread with a 2B tolerance. The thread is American UNF type, characterized by its bright surface and right-hand cut, ensuring optimal performance in various industrial applications.
