摘要： Cutting elements for earth-boring tools may generate a shear lip at a wear scar thereon during cutting. A diamond table may exhibit a relatively high wear resistance, and an edge of the diamond table may be chamfered, the combination of which may result in the formation of a shear lip. Cutting elements may comprise multi-layer diamond tables that result in the formation of a shear lip during cutting. Earth-boring tools include such cutting elements. Methods of forming cutting elements may include selectively designing and configuring the cutting elements to form a shear lip. Methods of cutting a formation using an earth-boring tool include cutting the formation with a cutting element on the tool, and generating a shear lip at a wear scar on the cutting element. The cutting element may be configured such that the shear lip comprises diamond material of the cutting element.

摘要： A drill bit (100) is provided that employs a plurality of discrete, post-like, abrasive, particulate-impregnated cutting structures (118) extending upwardly from the bit face. The cutting structures may be disposed on abrasive, particulate-impregnated blades (108) that also define a plurality of fluid passages (116) on the bit face (106). One or more of the cutting structures may include outermost ends that exhibit a cross-sectional geometry that is elongated in a direction along a defined axis. The cutting structures may be oriented such that the defined axis (132) is neither coplanar with, nor parallel to, an intended rotational path of the at least one discrete cutting structure during operation of the bit. In one embodiment, the cutting structure is oriented such that the defined axis is at an acute angle relative to a tangent of the intended rotational path for the associated cutting structure. Other or different features may include, for example, additional, differently configured cutting elements.

摘要： A method of constructing an earth-boring, diamond-impregnated drill bit has a first step of coating diamond grit with tungsten to create tungsten-coated diamond particles. These coated particles are then encapsulated in a layer of carbide powder held by an organic green binder material. The encapsulated granules are then mixed along with a matrix material and placed in a mold. The matrix material includes a matrix binder and abrasive particles. The mixture is heated in the mold at atmospheric pressure to cause the matrix binder to melt and infiltrate the encapsulated granules and abrasive particles.

摘要： An insert for a rolling cone earth-boring bit has a cylindrical base that interferingly presses into a mating hole formed in a cone of the bit. The insert has a convex end that extends from the base. A polycrystalline diamond cap is bonded to the convex end. The body is formed of at least two layers of carbide material having different mechanical properties, particularly a different modulus of elasticity. The first layer may have a metallic binder with a lesser percentage than the binder of the second layer to reduce the stress at the interface between the first layer and the diamond cap. The layers may have different average carbide grain sizes, with finer average grain sizes adjoining the diamond cap. Further, the layers may have different binders, with cobalt being the binder in the layer adjoining the diamond cap and either nickel or a nickel-cobalt alloy in another layer.
