The tapered fissure (cone) head cuts convergent walls and V-shaped grooves and tapers into narrow spaces. At 1.2 mm the head is small, suited to interdental areas, clasp spaces and fine detail rather than bulk work. As a medium crosscut cutter it does the main shaping work between bulk reduction and finishing.
