摘要： A cutting element includes a body, a non-planar cutting face formed on a first end of the body, and an edge formed around a perimeter of the cutting face. The cutting face includes a central raised portion, and the edge has an edge angle defined between the cutting face and a side surface of the body. The edge angle varies around the perimeter of the cutting face and includes an acute edge angle defined by a portion of the cutting face extending downwardly from the edge to a depth from the cutting angle. The portion of the edge defining the acute edge angle may be directly adjacent: a side surface of the cutting element; a bevel of the cutting element; or a flat region at the perimeter of the cutting element or bevel.

摘要： A downhole cutting tool includes a tool body having a tool axis, and a blade extending from the tool body. The blade includes a cutting face, a trailing face, and a top face extending between the cutting face and the trailing face. Cutting elements are attached to the bade along the cutting face, with each having a cutting crest at a peak height and a reduced height extending laterally away from the cutting crest. In some cases, first cutting elements along the cutting face and second cutting elements along the top face and rearward from, and at the same radial position as, the first cutting elements have different size, orientation, geometry or material properties. In additional aspects, at least two cutting elements on the blade have differing material properties, sizes, orientations, or working surface geometries along a blade profile of the blade.

摘要： A tool includes a base with a crown extending from the base. The crown is additively manufactured on the base, forming a bond between the crown and the base. At least one protrusion may extend from the base surface into a recess in the crown, such that the crown encompasses the protrusion. The protrusion may mechanically interlock the base and the crown to improve torque transfer between the crown and base. The bond at the contact between the base and crown may include impregnating at least a portion of the crown with the material of the base, or at least a portion of base with the material of the crown, which may improve a connection between the crown and base.

摘要： A bit includes a bit body having at least one blade coupled to the bit body. The blade has a plurality of cutting elements at a nose region and a shoulder region of the blade. A plurality of fluid outlets are positioned on the blade such that at least 30% of the cutting elements have a fluid outlet within a distance that is two or three times a cutting element diameter away from a cutting face of the cutting element.

摘要： A cutting element may include a substrate, an upper surface of the substrate including a crest, the crest transitioning into a depressed region, and an ultrahard layer on the upper surface, thereby forming a non-planar interface between the ultrahard layer and the substrate. A top surface of the ultrahard layer includes a cutting crest extending along at least a portion of a diameter of the cutting element, the top surface having a portion extending laterally away from the cutting crest having a lesser height than a peak of the cutting crest.
