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 fine crosscut toothing leaves a smoother surface than a standard crosscut, so this is the cutter for finishing edges and surfaces before polishing. At 3.1 mm the head is on the larger side, for covering wide acrylic surfaces in fewer passes.
