Patent attributes
A cutting element has 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. The cutting face has a non-planar geometry including a central region around a longitudinal axis of the cutting element, a plurality of grooves extending radially from a boundary of the central region to the cutting edge, wherein each groove has a base with a curved cross-sectional profile, and a plurality of lobes alternatingly formed between the plurality of grooves, wherein each lobe has a cross-sectional profile comprising an apex and opposite side surfaces sloping downwardly a distance from the apex to the base of adjacent grooves.
