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 (ZrAl)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.
