The tapered fissure (cone) head cuts convergent walls and V-shaped grooves and tapers into narrow spaces. A 2.3 mm head gives enough edge for shaping while still following tooth-sized contours. Its crosscut (double-cut) toothing removes stock quickly and clears chips well, so it is a shaping rather than a finishing cutter.
