PROBLEM TO BE SOLVED: To provide a hard-coating coated tool hardly reacting with a material in dry and high speed cutting, extremely improved in crater wear resistance. SOLUTION: In this hard coating coated tool coated with a hard coating on the base body surface, at least one layer of the hard coating contains boron and oxygen, the metallic component is an oxide nitride layer with Ti as the main component, expressed as TixMeyBz, where x, y and z satisfy x+y+z=100, 50x<100, 0.1<y<40 and 0.1<z<30; Me is at least one kind of elements of metals of groups 4a, 5a and 6a, such as Al, Si, Ca, K, Y, Mg, F excluding Ti, and the combining energy of Ti with oxygen and that of boron with nitrogen of the oxide nitride layer with Ti as the main component are confirmed by ESCA analysis.
