Machine tap made of high-performance high-speed steel. Suitable for through holes and blind holes in unalloyed steels up to 800 N/mm² strength. The thread is cut in a single operation. High-speed steel, primarily known as HSS, refers to a group of alloyed tool steels with up to 2.06% carbon content and up to 30% alloying elements such as tungsten, molybdenum, vanadium, cobalt, nickel, and titanium. HSS materials are characterized by high hardness, wear resistance, and heat resistance up to 600 °C. HSS tools are less sensitive to shocks and vibrations, which can quickly lead to breakage in harder cutting materials.
