Abstract

A cutting tool insert for machining by chip removal includes a body of a hard alloy of cemented carbide, cermet, ceramics or cubic boron nitride based material onto which a hard and wear resistant coating is deposited by CVD. The coating includes at least one multitextured α-Al2O3 layer with a thickness between 0.5 μm and 30 μm characterized with an ODF texture index>1 and at least two dominant texture components with 2<ODF density<100 coexisting within the layer. A method of making and using the cutting tool insert are also described.
