Abstract
A cutting element for use in drilling subterranean formations. The cutting element includes a superabrasive table mounted to a supporting substrate. The superabrasive table includes a two-dimensional cutting face having a cutting edge along at least a portion of its periphery, and a first surface extending forwardly and inwardly from a location radially interior of the cutting edge at a first angle of orientation with respect to the longitudinal axis of the cutting element. The cutting face also includes at least a second surface located between the first surface and the cutting edge and oriented at a different, greater angle to the longitudinal axis than the angle of orientation of the first surface.
