Each cutting tooth (22) has a flange (52) that is aligned flush with the external surface of the dome (24), and a raised cutting edge (50) extending above the flange and the external surface (36) of the dome, and an interior passageway (39) communicating between the outside and inside of the dome. In one embodiment, a base plate (56) is removably secured on the base portion (32) of the dome (24) to provide closure of the central cavity (34) of the dome.
