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 coarse crosscut is for bulk reduction: it takes material off fast and is followed by a medium or fine cutter. The 7.0 mm head is a bulk-reduction size: it covers a denture base quickly and is not meant for detail.
