COATED CUTTING TOOL
A coated cutting tool, comprising: a substrate made of a cubic boron nitride-containing sintered body; and a coating layer formed on the substrate, wherein the cubic boron nitride-containing sintered body includes 65 volume% or more and 85 volume% or less of cubic boron nitride, and 15 volume% or more and 35 volume% or less of a binder phase; the cubic boron nitride is in a form of particles, the particles having an average particle size from 1.5 µm or more to 4.0 µm or less; the coating layer includes a lower layer, and an upper layer formed on the lower layer; the lower layer contains particles each having a composition represented by (Ti 1 - x Al x )N; the lower layer has an average thickness from 0.1 µm or more to 1.0 µm or less; the particles forming the lower layer have an average particle size from 0.01 µm or more to 0.05 µm or less; the upper layer contains particles each having a composition represented by (Ti 1 - y Al y )(C 1 - z N z ); and the upper layer has an average thickness from 1.0 µm or more to 5.0 µm or less.
