Titanium Nitride (TiN)

The titanium nitride coating is a universal wear protection coating with a layer thickness of approx. 3 µm. It is ideally suited for taps as it reduces the coefficient of friction and the tendency to cold welds. Due to its high wear resistance, the coating allows higher cutting speeds and thus reduces unit costs.

Titanium Aluminium Nitride (TiAlN)

The TiAlN coating enables use even at high temperatures on the workpiece due to the incorporation of aluminum and combines this with the high wear resistance of the TiCN coating. It enables high cutting data and is the most suitable of all hard coatings for dry machining

Nitriding (NIT)

The CrN coating has excellent chemical resistance. It is particularly dense and protects the tool from corrosive attacks in particular. Due to the coating composition and the good temperature resistance, the coating is particularly suitable for cutting copper, brass and bronze alloys.

Titanium Carbon Nitride (TiCN)

The TiCN coating is harder than the TiN layer. This means excellent wear resistance, but also lower temperature resistance than TiN. The TiCN coating is particularly suitable for high-alloy steels and cast aluminum alloys with a high silicon content.

Chromuim Nitride (CrN)

The CrN coating has excellent chemical resistance. It is particularly dense and protects the tool from corrosive attacks in particular. Due to the coating composition and the good temperature resistance, the coating is particularly suitable for cutting copper, brass and bronze alloys.

Vaporizing (VAP)

Vaporizing is the enrichment of the surface layers on the tool with oxygen by a thermochemical process. The resulting iron oxide layer increases resistance to adhesion and corrosion resistance. This reduces the tendency to cold welds during steel machining. Recommended for machining low-alloy structural steels and stainless materials.
