<p>A cutting tool and method for cutting multidirectional cuts in a workpiece. The cutting tool (10) has a body portion (12) having a generally cylindrical outer wall (13) and inner periphery (11). A plurality of cutting teeth (22, 36, 50) are spaced circumferentially around the lower end and a plurality of flutes (14) extend upwardly around the outer periphery (13) from the lower end. The cutting teeth (22, 36, 50) include a plurality of generally radially extending cutting edges (36) positioned about the face of the cutting tool (10), a plurality of inside diameter cutting edges (50) formed at the line of intersection of the radially extending cutting edges (36) and the inner periphery (11) of the cylindrical wall, and a plurality of outside diameter cutting edges (22) formed at the line of intersection of the radially extending cutting edges (36) and the outer periphery (13) of the cylindrical wall. The method includes the ability to move the cutting tool (10) in a direction coincident to the axis of rotation of the cutting tool (10) and at angles to the rotational axis of the cutting tool (10), either sequentially or simultaneously to obtain cuts with complex contours with each of the directions of cutting having generally the same cutting capacity.</p> |
