Ruko Machine tap M DIN 376 HSS, ground M 12 type C / 35° 2335120

metric DIN ISO 13 - Machine taps with overflow shank and 35° right hand spiral flutes for bottoming. The machine tap consists of heavy duty high speed steel. For bottoming threads in unalloyed steels up to a strength of 800 N/mm², malleable. The thread is cut in one operation. High speed tool steel, best known as ’high speed steel’, refers to a group of alloyed tool steels with up to 2.06% carbon content and up to 30% proportion of alloying elements such as tungsten, molybdenum, vanadium, cobalt, nickel and titanium. HSS materials are characterised by great hardness, wear resistance and heat resistance up to 600° C. The HSS tools are less sensitive to shocks and vibrations, which sometimes quickly lead to breaks in the harder cutting materials.
