    摘要： Polycrystalline elements include a substrate and a polycrystalline table attached to an end of the substrate. The polycrystalline table includes a first region of superabrasive material having a first permeability and at least a second region of superabrasive material having a second, lesser permeability, the at least a second region being interposed between the substrate and the first region. Methods of forming a polycrystalline element involve attaching a polycrystalline table including a first region of superabrasive material having a first permeability and at least a second region of superabrasive material having a second, lesser permeability to an end of a substrate, the at least a second region being interposed between the first region and the substrate. Catalyst material is removed from at least the first region of the polycrystalline table.

The cutting elements include at least one shearing cutting element and at least one gouging cutting element. Methods of forming an earth-boring tool include mounting a shearing cutting element comprising an at least substantially planar cutting face to a body of an earth-boring tool, and mounting a gouging cutting element comprising a non-planar cutting face to the body of the earth-boring tool. The gouging cutting element may be positioned on the body of the earth-boring tool such that the gouging cutting element will gouge formation material within a kerf cut in the formation material by the shearing cutting element, or between kerfs cut in the formation material by a plurality of shearing cutting elements.

    摘要： A cutting element for use in drilling subterranean formations. The cutting element includes a superabrasive table mounted to a supporting substrate. The superabrasive table includes a two-dimensional cutting face having a cutting edge along at least a portion of its periphery, and a surface comprising a chamfer extending forwardly and inwardly from proximate a peripheral cutting edge at a first acute angle of orientation of greater than about 45° with respect to the longitudinal axis of the cutting element, and to no greater than a selected depth. The chamfer may be arcuate or planar, and of a dimension sufficient to ensure that a wear flat generated during use of the cutting element remains outside the inner boundary of the chamfer within the chamfer envelope, and small enough to maintain aggressive cutting characteristics for the cutter. Drill bits and drilling tools bearing the cutting elements are also disclosed.
