SURFACE-COATED CUTTING TOOL WITH EXCELLENT CHIPPING RESISTANCE AND WEAR RESISTANCE
In a surface-coated cutting tool, an A layer made of an (Al 1-x Ti x )N layer (here, 0.35 ¤ x ¤ 0.6 by an atom ratio) and a B layer made of a (Al 1-y-z Ti y Si z )N layer (here, 0.35 ¤ y ¤ 0.6 and 0.01 ¤ z ¤ 0.1 by an atom ratio) are layered and coats a surface of a tool body in which at least a cutting edge is made of a cBN sintered body, a layer thickness ratio of the A layer and the B layer (t B /t A ) is set to be 2 to 5, an X-ray diffraction intensity ratio I(200)/I(111) as the entire hard coating layer is set to be more than 3 and 12 or less, a full width at half maximum of a peak of I(200) is 0.3 to 1.0, the I A (200)/I A (111) of the A layer is desirably set to be more than 2 and 10 or less, and a full width at half maximum of the peak of the I A (200) is 0.3 to 1.0.
