Abstract
An earth-boring tool includes a body, at least one blade extending axially from the body, at least one cutting element mounted at a leading face of the at least one blade and at least one hybrid ovoid mounted at an axial end of the at least one blade and rotationally trailing the at least one cutting element. The at least one hybrid ovoid includes a cylindrical base portion, a domed upper portion extending from a top of the cylindrical base portion, and an at least substantially planar cutting surface formed in at least the domed upper portion and defining a cutting edge extending angularly through an angle of at least 180°, the at least substantially planar cutting surface is configured for a shear-type cutting action, oriented substantially in the direction of intended bit rotation, and exhibits a lesser aggressiveness than the aggressiveness of the at least one cutting element.
