The tapered fissure round head combines convergent sides with a rounded tip, for tapered grooves and contours without a sharp floor. As a medium crosscut cutter it does the main shaping work between bulk reduction and finishing. At 1.2 mm the head is small, suited to interdental areas, clasp spaces and fine detail rather than bulk work.
