Monobloc machine tap 261 series

spiral flutehigh-speed steelHSSE-Co 5

Machine tap made of cobalt-alloyed high-performance high-speed steel, with overflow shank and right-hand spiral flutes 35° RSP for blind hole threads. The higher hot hardness resistance results in a longer service life. For through threads and blind hole threads in unalloyed and alloyed steels up to 1000 N/mm² strength and non-ferrous metals. The thread is cut in a single operation. Like HSS high-speed steel, with 5% cobalt alloy. This heat-resistant material is used for machining materials with higher strength and for long cutting channels with correspondingly high heat generation. The 5% cobalt content ensures higher heat resistance and higher load capacity. Schematic illustration. Smaller diameters may be supplied with a point due to production reasons.
