The thread is cut in one operation. Note: Cutting speeds from 10 m/min.
The TiN anti-wear coating increases the surface hardness to approx. 2,500 HV. Titanium nitride is a chemical compound of the two elements titanium and nitrogen. TiN is a hard metallic material typically of a golden yellow colour. Advantages: Higher hardness, low friction coefficient, longer tool life. Cooling is not necessary, but is recommended.
