Abstract
A cutting tool with excellent resistance to adhesion and wear. The cutting tool has a cutting edge on the intersecting ridge line of the rake face and the flank face, and is covered on the surface of the base thereof by a coating layer comprising TiAlNbM(CN). M is at least one selected from Si, W, Mo, Ta, Hf, Cr, Zr, and Y, with the content ranges 0.3≦a≦0.8, 0≦b≦0.6, 0.01≦d≦0.25, 0≦e≦0.25, a+b+d+e=1, and 0≦x≦1). Droplets provided on the surface of the coating layer have a higher Nb content ratio on the rake face compared to the flank face.
