Abstract
A cutting tool including a base member and a coating layer. The base member includes a rake face and a flank face. The coating layer has a composition represented by a first chemical formula of CrM(CN), wherein M represents at least one selected from Ti, Al, Si, W, Mo, Ta, Hf, Nb, Zr, and Y, 0.01≦a≦0.5, and 0≦x≦1. The coating layer is disposed on the base member and includes a cutting edge at an intersecting ridge line between the rake face and the flank face. The coating layer further comprises droplets thereon. An average composition of the droplets disposed on the rake face has a Cr content higher than the Cr content of the average composition of the droplets disposed on the flank face.
