The bud round head is a full oval with a rounded tip, for contouring concave and lingual denture surfaces without digging in. The 8.0 mm head is a bulk-reduction size: it covers a denture base quickly and is not meant for detail. A coarse single cut is a bulk-reduction toothing: use it for gross trimming, not for finishing.
