摘要： Provided is a cutting tool which has high weld resistance and wear resistance. The cutting tool (8) includes: a base (1) including cemented carbide containing Cr; and a coating layer (7) including a Ti-based layer (2) including at least a layer of Ti(C x1 N y1 O z1 ) (0 ≤ x1 ≤ 1, 0 ≤ y1 ≤ 1, 0 ≤ z1 ≤ 1, x1 + y1 + z1 = 1), an Al 2 O 3 layer (5), and an outermost layer (6) of Ti(C x3 N y3 O z3 ) (0 ≤ x3 ≤ 1, 0 ≤ y3 ≤ 1, 0 ≤ z3 ≤ 1, x3 + y3 + z3 = 1), which are laminated in order from the base side on the surface of the base (1), and a content of Cr contained at a thickness-center position of a first Ti-based layer (2a) of the Ti-based layer (2) on a side closer to the base is lower than a content of Cr contained in the base (1), and higher than a content of Cr contained at a thickness-center position of the Al 2 O 3 layer (5), and a content of Cr contained at a thickness-center position of the outermost layer (6) is higher than the content of Cr contained at the thickness-center position of the Al 2 O 3 layer (5) in a glow-discharge emission spectrometry (GDS analysis).

摘要： Provided is a cutting tool such that the progress of wear is delayed and that wear resistance is excellent. This cutting tool is configured in such a way that multiple cover layers (7, 8, 9, 10, 11, 12, 14) are formed on the surface of a substrate (6); that the outermost layer (14), which is one of the cover layers, comprises a Ti(C x N y O z ) a (x + y + z = 1,0 ≤ x ≤ 0.6, 0 ≤ y 0 ≤ 0.6, 0.2 ≤ z ≤ 0.8, 1.0 ≤ a ≤ 1.7) layer; and that the thickness of that portion of the outermost layer (14) which is located in the center section (3a) of a flank surface is smaller than the surface roughness (Ra) of the outermost layer (14). The outermost layer (14) comes into contact with an article to be cut, leading to a coating being generated, with the result that the progress of wear is restricted.
