The round head cuts in every direction, which makes it the shape for opening, hollowing and relieving acrylic, plaster and model surfaces rather than for flat work. The 5.0 mm head is a bulk-reduction size: it covers a denture base quickly and is not meant for detail. Its crosscut (double-cut) toothing removes stock quickly and clears chips well, so it is a shaping rather than a finishing cutter.
