The present invention is an annular cutting tool (18) for use with a low profile self-adhering drill (10). The cutting tool has a shank portion (180) and a cutting portion (182). The cutting portion includes a cutting surface (184) and inner (185) and outer (186) surfaces that taper back towards the shank portion. The cutting surface has a plurality of cutting teeth (200). Each of the cutting teeth have a plurality of cuttings edges, which are angled with respect to the horizontal plane. The outer cutting edges initially cut the workpiece surface so that the cutting tool immediately seats itself in the intended area of the workpiece. After the outer edges begin the cut, the inner edges begin to cut and form a kerf. <IMAGE>The present invention is an annular cutting tool (18) for use with a low profile self-adhering drill (10).
