Machine tap set M DIN 371 / 376 Form B HSS-Co 5 TiAlN with progressive tap - 7 pcs.

Machine tap made from high-speed steel (HSS). For through-hole and blind-hole threads in unalloyed, low-alloyed, alloyed steels up to 1.200 N/mm² strength and cast iron.

The TiAlN wear protection coating increases the surface hardness to approx. 3,500 HV. Titanium aluminum nitride is a chemical compound of the three elements titanium, aluminum and nitrogen. TiAlN is a metallic hard material with a typical black-violet color. Advantages: The TiAlN coating enables dry machining of cutting tools, cooling is not necessary. Higher hardness, very low coefficient of friction, optimum tool life.

The thread is cut in a single operation.
