Abstract
A cutting tool insert for machining by chip removal includes a body of a hard alloy of cemented carbide, cermet, ceramics, cubic boron nitride based material or high speed steel, onto which a hard and wear resistant coating is deposited. The coating includes at least one polycrystalline nanolaminated structure having sequences of alternating A and B layers, wherein layer A is (Alx1Mel1-x1)Ny1 with 0.3<x1<0.95, 0.9<y1<1.1 and Me1 is one or more of the elements Ti, Y, V, Nb, Mo, Si and W, or Me1 is Ti and one or more of the following elements Y, V, Nb, Mo, Si, Cr and W, and layer B is (Zr1-x2-z2Six2Me2z2)Ny2 with 0<x2<0.30, 0.90<y2<1.20, 0≦z2<0.25 and Me2 is one or more of the elements Y, Ti, Nb, Ta, Cr, Mo, W and Al.
