摘要:
The present invention relates to a cutting tool insert for machining by chip removal comprising 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. Said coating comprises at least one multitextured α-Al 2 O 3 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
