Abstract
A surface-coated cutting tool includes a tool body and a hard coating layer, where one TiAlCN layer α () containing 70 area % or more of a wurtzite type hexagonal structure on a tool surface side (S) and one TiAlCN layer β () containing 70 area % or more of a NaCl type face-centered cubic structure on the tool body side (B), when a composition of the TiAlCN layer α () is represented by (TiAl)(CN) satisfying 0.70≤xα≤0.95 and 0.000≤yα≤0.010, when a composition of the TiAlCN layer β () is represented by (TiAl)(CN) satisfying 0.65≤xβ≤0.95 and 0.000≤yβ≤0.010, and when average layer thicknesses of the TiAlCN layer α () and the TiAlCN layer β () are defined as Lα and Lβ satisfying 0.5 μm≤Lα≤10.0 μm and 1.0 μm≤Lβ≤20.0 μm.
