Abstract

Cutting elements for an earth boring tool include a substrate base and a cutting tip. The cutting tip may include a first generally conical surface a second opposite generally conical surface a first flank surface extending between the first and second generally conical surfaces and a second opposite flank surface. In some embodiments the cutting tip includes a central axis that is not co linear with a longitudinal axis of the substrate base. In some embodiments the cutting tip includes a surface defining a longitudinal end thereof that is relatively more narrow in a central region thereof than in a radially outer region thereof. Earth boring tools include a body and a plurality of such cutting elements attached thereto at least one cutting element oriented to initially engage a formation with the first or second generally conical surface thereof. Methods of drilling a formation use such cutting elements and earth boring tools.
