Beskrivelse
Thread: american UNF fine thread – Machine taps with overflow shank for through threads. The machine tap consists of cobalt alloyed heavy-duty high-speed steel. Its high heat resistance means a longer tool life. For through threads in unalloyed and alloyed steels up to a strength of 1000 N/mm², malleable cast iron and non-ferrous metals. The thread is cut in one operation. Like high speed steel with cobalt alloy. This heat-resistant material is used for processing materials with high strength and in long cutting channels with correspondingly strong heating. The cobalt content of 5% provides a higher heat resistance and higher stressing capacity.
