The taper (cone) round head is the all-purpose lab contouring shape: the cone reaches into interdental areas and around clasps while the rounded tip avoids gouging. The super coarse crosscut has the most aggressive toothing in the range: it is for rapid bulk reduction where speed matters more than surface quality. At 7.0 mm the head is one of the largest in the range, for rapid reduction of large surfaces.
