摘要： A drill bit is provided that employs a plurality of discrete, post-like, abrasive, particulate-impregnated cutting structures extending upwardly from the bit face. The cutting structures may be disposed on abrasive, particulate-impregnated blades that also define a plurality of fluid passages on the bit face. 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 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： A method of producing a drill bit, such as for drilling a well into an earth formation, includes forming a bit body having a plurality of blades. Each of the plurality of blades includes a forward facing face with respect to a direction of rotation of the bit. The forward facing face includes individual cutter pockets at least partially recessed into the forward facing face. The method also includes securing a cutting element at least partially within each of the individual cutter pockets. Each cutting element has an abrasion resistance. Each of the plurality of blades is formed of a blade material having an abrasion resistance that is less than the abrasion resistance of the cutting element.
