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 0.8 mm the head is a small size for detail work and confined spaces. The crosscut pattern gives fast, cool material removal; follow with a fine cut for the final surface.
