1. A cutting element comprising:
a substrate; and
a table composed of polycrystalline diamond material, the table affixed to the substrate at an interface, the table comprising:
a raised cutting surface at least partially defined by and extending between at least two cutting edges, the raised cutting surface being planar and extending substantially orthogonally to a longitudinal center axis of the cutting element;
a longitudinal side surface at a periphery of the table;
first planar transition surfaces extending radially outward from portions of the raised cutting surface to the longitudinal side surface;
wherein a plurality of the first planar transition surfaces is between two adjacent cutting edges, and wherein the first planar transition surfaces connect the portions of the raised cutting surface to an entirety of a portion of the longitudinal side surface between the at least two cutting edges, each of the at least two cutting edges comprising a chamfer surface located directly between and intersecting the raised cutting surface and the longitudinal side surface and extending circumferentially a distance along a perimeter of the raised cutting surface.
