Abstract
A cutter element for a drill bit includes a base portion having a central axis, a first end, and a second end. In addition, the cutter element includes a cutting layer fixably mounted to the first end of the base portion. The cutting layer includes a cutting face distal the base portion. The cutting face includes a first planar surface and a second planar surface that is circumferentially-spaced from the first planar surface. Each planar surface is positioned at an outer periphery of the cutting face adjacent the radially outer surface of the cutting layer. The cutting face also includes a saddle surface including a crown and a pair of lateral side surfaces that slope down and away from the crown toward the radially outer cylindrical surface of the cutting layer. The crown extends from the first planar surface to the second planar surface.
