Abstract
A cutting tool insert includes a body of a hard alloy of cemented carbide, cermet, ceramics, cubic boron nitride based material or high speed steel. A hard and wear resistant coating, having at least one layer, to which an (Al,Cr)Olayer is applied. This insert is particularly useful for machining of steel and stainless steel. The coating with a total thickness of 2-20 μm has one or several layers, at least one of which is an (Al,Cr)Olayer with a thickness of 1-5 μm having a corundum phase crystalline structure and a composition (AlCr)Owith 0.4≦y≦0.6. The (Al,Cr)Olayer has a fiber texture with rotational symmetry in the direction of the coated surface normal to an inclination angle, φ, of the basal planes relative to the coated surface normal or the inclination angle, φ, for the highest peak in the pole plot with 70° <φ<90° .
