Beschreibung
Zusammenfassung:	The present invention relates to a cutting tool for metal machining with improved wear properties, comprising a cutting tool substrate of cemented carbide, cermet, ceramics or a super hard material, and a wear resistant coating, wherein the wear resistant coating comprises a PVD Ti-Si-C-N layer, and a method of making thereof. The method includes loading the coating tool into a substrate holder (B) in a PVD chamber with arc evaporation using one or more Ti targets (A). Trimethylsilane gas is added to a reactive gas atmosphere in the chamber.
