| US8794356B2 The earth-boring tool features shearing cutting elements with planar faces and gouging cutting elements with non-planar faces, enhancing material removal efficiency. The gouging elements are positioned to crush and gouge formation material after shearing, optimizing drilling performance. The design ensures improved durability and cutting precision under applied rotational force. | 1. 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. |
| US9303461B2 The cutting element incorporates polycrystalline hard material with an annular configuration and apertures, enhancing material removal. The design features radial width optimization for precision cutting and reduced wear. The aperture structure ensures efficient debris removal during drilling operations. | 1. A cutting element for an earth-boring tool, comprising: a substrate having a front end surface, an opposing back end surface, and at least one side surface extending between the front end surface and the back end surface; and a volume of polycrystalline hard material disposed on the front end surface, the volume of polycrystalline hard material having an annular configuration defining at least one aperture extending through the volume of polycrystalline hard material, the volume of polycrystalline hard material having an average radial width in radial directions perpendicular to a longitudinal axis of the cutting element of 3.0 mm or less, the at least one aperture devoid of solid material and at least partially defining a volume of space within the cutting element having one or more openings through the volume of polycrystalline hard material to the volume of space from the exterior of the cutting element. |
| US10450807B2 The cutting element features superabrasive material with intersecting surfaces and edges for enhanced cutting. The design includes curved and planar lateral surfaces, optimizing material engagement and wear resistance. The configuration ensures precision cutting and durability in earth-boring applications. | 1. A cutting element for an earth-boring tool, comprising: a generally planar front-cutting surface; a generally planar end-cutting surface; a first generally planar lateral side surface; a first curved lateral side surface extending between the front-cutting surface and the first generally planar lateral side surface; a second generally planar lateral side surface; a second curved lateral side surface extending between the generally planar front-cutting surface and the second generally planar lateral side surface; and a base end surface on an opposing side of the cutting element from the generally planar front-cutting surface; wherein an average width of the generally planar front-cutting surface measured perpendicularly to an axis of the cutting element is less than an average width of the base end surface measured perpendicularly to the axis of the cutting element. |
