Beskrivelse
metric DIN ISO 13 – Machine taps with reinforced 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.
