Earth-boring tools including shaped cutting elements, and related methods |
摘要 |
A cutting element for an earth-boring tool. The cutting element comprises a substrate base, and a volume of polycrystalline diamond material on an end of the substrate base. The volume of polycrystalline diamond material comprises a generally conical surface, an apex centered about a longitudinal axis extending through a center of the substrate base, a flat cutting surface extending from a first point at least substantially proximate the apex to a second point on the cutting element more proximate a lateral side surface of the substrate base. Another cutting element is disclosed, as are a method of manufacturing and a method of using such cutting elements. |

1. An earth-boring tool, comprising:
at least one shaped cutting element attached to at least one structure of the earth-boring tool, the at least one shaped cutting element comprising:
a substrate base attached to at least one surface of the at least one structure; anda volume of polycrystalline diamond material on an end of the substrate base, the volume of polycrystalline diamond material comprising:
an apex centered about a longitudinal axis extending through a center of the substrate base;a generally conical surface extending at a first angle from the substrate base to the apex; anda flat cutting surface opposing the generally conical surface and extending at a second, different angle from a first point at least substantially proximate a center of the apex to a second point on the at least one shaped cutting element more proximate a lateral side surface of the substrate base. |
