Zusammenfassung:A cutting element for use with a drill bit includes a substrate having a longitudinal axis, a lateral surface substantially symmetric about the longitudinal axis and one or more key elements coupled to the lateral surface. The lateral surface lies between an insertion end and a cutting end of the substrate. The one or more key elements are substantially axially aligned with the longitudinal axis and configured to selectively rotationally locate the substrate in a pocket. A drill bit configured for retaining a cutting element having one or more key elements is also disclosed.
