Abstract

The present invention relates to a cutting tool insert comprising a body of cemented carbide, cermet, ceramics, high speed steel (HSS), polycrystalline diamond (PCD) or polycrystalline cubic boron nitride (PCBN), a hard and wear resistant coating is applied, grown by physical vapour deposition (PVD) such as cathodic arc evaporation or magnetron sputtering. Said coating comprises at least one layer of (ZrxAl1-x)N with of 0.45<x<0.85 and 0.90≦y<1.30 with a thickness between 0.5 and 10 μm. Said layer has a nanocrystalline microstructure consisting of a single cubic phase or a mixture of hexagonal and cubic phases. The insert is particularly useful in metal cutting applications generating high temperatures with improved crater wear resistance.
