The machine tap consists of heavy-duty high-speed steel with a titanium nitride coating. For universal use on a wide range of materials due to layer of hard material For through threads and bottoming threads in unalloyed and alloyed steels up to a strength of 900 N per square millimetre, stainless steel. The thread is cut in one operation. Note: cutting speeds from 10 m/min. By the TIN wear-resistant coating, The surface hardness increases to about 2500 HV. Titanium nitride is a chemical compound of the two elements, titanium and nitrogen. Tin is a metallic hard material with a typical Golden yellow colour. Advantages: increased hardness, low friction coefficient, more service life. *Cooling is not necessary, but recommended.
