摘要： A chisel insert for rolling cone rock bits is disclosed in which the crest of the insert has a "dog bone" shape by being rounded with the crest ends flaring out to a larger dimension than the middle thereof. The crest is also convex upwardly along its median line thereby making a shorter moment arm at the ends of the crest.

摘要： A cutter element for a drill bit has a crest that defines a crest line. The crest can be non-rectilinear. The crest line of each cutter element defines an angle with respect to the axis of the rolling cone on which the cutter element is mounted. The cutter elements define different angles with respect to the cone axis and with respect to each other.

摘要： A cutter element for a drill bit has a non-rectilinear crest. The cutter element has a base portion and an extending portion and the extending portion has either a zero draft or a negative draft with respect to the base portion. The non-positive draft allows more of the borehole bottom to be scraped using fewer cutter elements. The cutter elements having non-positive draft can be either tungsten carbide inserts or steel teeth.

摘要： A cutter element for a drill bit. The cutter element has a non-rectilinear crest. The non-rectilinear or curvilinear crest provides an advantageous distribution of the cutting forces across the body of the cutter elements and thus improves bit life. The curvilinear crest also allows the cutter element to more efficiently lift the portion of the formation that is being cut, thereby improving cutting action in certain formations. The cutter elements can have either positive or non-positive draft and can be tungsten carbide inserts.

摘要： A cutter element for use in a drill bit, comprising a substrate and a cutting layer. The substrate comprises a grip portion and an extension portion, where the grip portion has an insert axis and an extension portion including an interface surface having a first apex. The cutting layer is affixed to the interface surface and has a cutting surface having a second apex. The cutting layer is shaped such that when a plane passing through the first apex and lying parallel to the insert axis and normal to a radius from the insert axis, the plane divides the cutting layer into major and minor portions and the major portion has a major volume that is at least 60 percent of the total volume of said cutting layer. Alternative embodiments of the present invention include variations wherein the first and second apices do not coincide and wherein the interface surface of the substrate is not axisymmetric. Using these variations, cutter elements having sizeable variations in thickness are constructed.

摘要： Enhanced inserts are formed having a cylindrical grip and a protrusion extending from the grip. An ultra hard material layer is bonded on top of the protrusion. The inserts are mounted on a rock bit and contact the earth formations off center. The ultra hard material layer is thickest at a critical zone which encompasses a major portion of the region of contact between the insert and the earth formation. Transition layers may also be formed between the ultra hard material layer and the protrusion so as to reduce the residual stresses formed on the interface between the ultra hard material and the protrusion.

摘要： Cutting elements offering increased toughness and thermal fatigue resistance can be formed of a wear resistant material having coarse grains disposed in a binder matrix with a binder content of at least about 18% by weight. The coarse grains include grains of at least one selected from the group of a transition metal carbide, a transition metal boride, and transition metal nitride. The binder content and coarse grain size may be selected to provide a Rockwell A hardness of at least about 75 Ra or a wear number of at least about 1.5.

摘要： A polycrystalline diamond enhanced insert is disclosed. The insert includes a body portion adapted for attachment to an earth-boring bit and a top portion for contacting an earthen formation. The top portion of the insert is provided with two different compositions of polycrystalline diamond. In the primary surface of the top portion, a tougher or less wear-resistant polycrystalline diamond layer is provided, whereas a more wear-resistant polycrystalline diamond layer is provided in the remaining region of the top portion. In addition to polycrystalline diamond, polycrystalline boron nitride and other superhard materials also may be used.
