• a bit body having a central axis extending axially through the bit body;
• a plurality of blades extending outwardly from the bit body;
• and
• a plurality of cutting elements mounted on the blades, wherein each cutting element comprises:
• a longitudinal axis extending axially through the cutting element;
• a cutting face at an axial end of the cutting element;
• a peripheral surface extending circumferentially around the cutting face;
• and
• a cutting edge formed between the cutting face and the peripheral surface;
• wherein the cutting face has a non-planar geometry comprising:
• a central region around a longitudinal axis of the cutting element;
• at least 24 grooves extending radially from a boundary of the central region to the cutting edge;
• and
• at least 24 lobes alternatingly formed between the grooves, each lobe having a cross-sectional profile comprising an apex and two opposite side surfaces extending between the apex and adjacent grooves on opposite sides of the lobe.
