Plow-shaped cutting elements for earth-boring tools, earth-boring tools including such cutting elements, and related methods

摘要

A cutting element for an earth-boring tool includes at least one volume of superabrasive material on a substrate. The volume of superabrasive material includes a first planar surface and a second planar surface oriented at an angle relative to the first planar surface and intersecting the first planar surface along an apex. The first planar surface has a circular or oval shape having a first maximum diameter, and the second planar surface has a circular or oval shape having a second maximum diameter. The apex has a length less than the first maximum diameter and the second maximum diameter. Earth-boring tools includes such a cutting element attached to a body. Methods of forming earth-boring tools include the attachment of such a cutting element to a body of an earth-boring tool.

1. A cutting element for an earth-boring tool, comprising:
a substrate; and at least one volume of superabrasive material on the substrate, the at least one volume of superabrasive material including a first planar surface and a second planar surface oriented at an angle relative to the first planar surface and intersecting the first planar surface along an apex; wherein the first planar surface has a first shape comprising more than half of a circle or more than half of an oval, the first shape having a first maximum diameter, the second planar surface has a second shape comprising more than half of a circle or more than half of an oval, the second shape having a second maximum diameter, and the apex has a length less than the first maximum diameter and the second maximum diameter, wherein notches extend in a lateral side surface of the at least one volume of superabrasive material on opposing sides adjacent the apex.
