Zusammenfassung:A downhole tool comprising a bit body and a plurality of blades. Each blade having at least one cutting element disposed within the blade. Each cutting element comprising a substrate and a poly crystalline diamond material affixed to the substrate at an interface. The poly crystalline diamond material comprising a raised cutting surface comprising at least two cutting edges, a recess in a center of the raised cutting surface, and transition surfaces between the at least two cutting edges of the raised cutting surface and a side surface of the cutting element. The disclosure also includes a method of manufacturing a downhole tool comprising: forming a drill bit, blades, and cutting elements. Forming the cutting elements comprises forming a raised cutting surface comprising at least two cutting edges, forming a recess in a center of the raised cutting surface and forming transition surfaces between the raised cutting surface and a side surface of the cutting element.
