Patent ID: 8794356

Claim:
An earth-boring tool, comprising: a body; at least one blade projecting outwardly from the body; and a plurality of cutting elements carried by the at least one blade, the plurality of cutting elements comprising: at least one shearing cutting element comprising an at least substantially planar cutting face positioned and oriented for shearing a surface of a subterranean formation when the earth-boring tool is rotated under applied force against the subterranean formation; and at least one gouging cutting element located rotationally behind the at least one shearing cutting element on the at least one blade, the at least one gouging cutting element having a longitudinal central axis angled with respect to a plane perpendicular to the surface of the subterranean formation such that the at least one gouging element has a forward rake angle greater than approximately fifteen degrees, the at least one gouging cutting element comprising a non-planar cutting face positioned and oriented for at least one of crushing and gouging the surface of the subterranean formation when the earth-boring tool is rotated under the applied force.
