Abstract:
A surface-coated cutting tool according to the present invention includes a base material and a coating film formed on the base material. The coating film includes at least one TiCN layer. The TiCN layer has a columnar crystal region. The columnar crystal region is characterized by having a composition of TiCxNy (in which 0.65≦x/(x+y)≦0.90) and having a (422) plane having a plane spacing of 0.8765 Å to 0.8790 Å.
