PROBLEM TO BE SOLVED: To provide a rotating tool having high wear resistance and high chipping resistance. SOLUTION: In this rotating tool such as an end mill 1, a coating layer 10 is coated on a surface of a substrate 9 provided with at least one bottom blade on a distal end surface of a tool main body rotating around a center axis and at least one outer peripheral blade on an outer peripheral surface, a plurality of macro particles 11 are projected on a surface of the coating layer 10, and the macro particles 11 are projected at an average angle 5-20°in a direction away from cutting edges of the bottom blade and outer peripheral blade in a perpendicular direction of a boundary face of the substrate 9 and the coating layer 10 in a rake face 13 continuous to cutting edges. The rotating tool has high wear resistance and high chipping resistance. COPYRIGHT: (C)2009,JPO&INPIT
