Machine tap M DIN 371 HSSE-Co 5 TiAlN, ground

The machine tap consists of heavy-duty high-speed steel. For through-hole threads and blind-hole threads, in unalloyed, low alloy and alloyed steels up to 1200 N/mm² strength and cast. The thread is cut in one operation. By the TiAIN wear-resistant coating, the surface hardness increases to about 3500 HV. Titanium aluminium nitride is a chemical compound of three elements titanium, aluminium and nitrogen. TiAIN is a metallic hard material with a typical black/violet colour. Advantages: The TiAlN coating enables the dry machining tools to cut without a cooling. Increased hardness, very low friction coefficient, optimal service life.
