Abstract: A cutting tip is coupled with a rotor, which operates in response to actuation of a motor, in order to cut or process a workpiece. The cutting tip includes a plurality of first cutting recesses formed in upper and lower edges of one face of the cutting tip, which comes in contact with the workpiece; and a plurality of second cutting recesses, alternating with the first cutting recesses in a plan view, the second cutting recesses having a conical shape. The first and second cutting recesses in the cutting tip can minimize the abrasion of the cutting tip when cutting workpiece, enhance cutting power, and increase lifetime.
