Machine tap set M DIN 371 / 376 Form B HSS with progressive tap - 7 pcs.

Machine taps made of high-speed steel (HSS) for through threads and blind holes in unalloyed steels up to 800 N/mm² strength. The thread is cut in a single operation.

High speed steel refers to a group of alloy 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 characterised by high hardness, wear resistance and heat resistance up to 600°C and are less sensitive to shocks and vibrations, which can quickly lead to breakage in harder cutting materials.
