ABSTRACT:
A cutting tool consists of a cutting body extending from a front end to a rear end and defined by at least an exterior surface. A shank is connected to the cutting body at the rear end. The cutting body is provided with a slightly concave base surface positioned at the front end. A pilot unit extends outwardly from the base surface and is defined by at least an outside surface thereof. First and second surfaces extend inwardly from the exterior surface of the cutting body and intersect each other to form a flute. The first surface, second surface and the flute extend into the pilot unit. A cutting edge of the cutting tool is formed at the intersection of the first surface with the base surface of the cutting body.
