iCN (Titanium carbonitride coating): coating belongs to the PVD category, color is generally blue gray. TiCN combined with the properties of TiC and TiN, which combines high hardness of TiC coating, and has the advantages of high binding strength TiN. So TiCN has lower friction coefficient than TiN coating, better abrasion resistance, anti adhesion properties, can further improve the production efficiency and the service life of the cutting tool. So TiCN coating saw blade in cutting sticky metals such as copper and stainless steel work piece, with very significant sawing effect.
