Surface coating cutting tool with excellent chipping resistance

The invention provides a surface coating cutting tool with excellent chipping resistance. The tool is a cBN sintered body cutting tool which maintains long-term excellent cutting performance and will not break when cutting high-hardness steel that needs high load cutting conditions during a high-speed cutting process. A hard coating layer of the surface coating cutting tool is formed by an A layer formed on the surface of a tool base body and a B layer arranged thereon. The A layer contains Ti1-aA1aN, wherein 0.3<=a<=0.7. The B layer contains Ti1-b-cA1bSicN, wherein 0.3<=b<=0.7, and 0.01<=c<=0.1. On the back blade surface of the tool base body, spherical recesses are formed on surfaces of cubic boron nitride particles that contact the hard coating layer.
