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. At 4.5 mm the head is on the larger side, for covering wide acrylic surfaces in fewer passes. Fine crosscut teeth trade removal speed for surface quality: use it after shaping, as the last cutting step before polishers.
