The bud pointed head tapers to a point so it can contour the lingual surface and then run into interdental and gingival areas. With its fine crosscut it is a finishing cutter, smoothing what a medium or coarse cutter has shaped. A 2.3 mm head gives enough edge for shaping while still following tooth-sized contours.
