摘要： Methods of manufacturing roller cones for drill bits include providing both integral teeth and non-integral teeth on the roller cones. A layer of hardfacing may be applied to the integral teeth. Non-integral teeth may be formed on a body of a cone, or they may be separately formed from the body and attached thereto. In some embodiments, the non-integral teeth are formed by building-up the non-integral teeth from hardfacing material. Roller cones and earth-boring tools are formed using such methods.

摘要： A drill bit having steel teeth is provided with a combination of hardfacing materials on the teeth. The bases of the teeth are hardfaced with nickel-based materials to significantly reduce any potential cracking therein. Portions of the supporting cones adjacent the teeth also may be fabricated with the nickel-based hardfacing. All other portions of the teeth are hardfaced with iron-based materials.

摘要： Drill bits with at least two roller cones of different diameters and/or utilizing different cutter pitches in order to reduce bit tracking during drilling operations are described. In particular, earth boring drill bits are provided, the bits having two or more roller cones, and optionally one or more cutter blades, the bits being arranged for reducing tracking by the roller cone teeth during operation by adjusting the teeth spacing, cone pitch angle, and/or the diameter of one or more of the cones. These configurations enable anti-tracking behavior and enhanced drilling efficiency during bit operation.

摘要： A drill bit with a bit body having a central bore in communication with a plurality of nozzles for directing drilling fluid; a plurality of cutters defining a cutting face of the bit; and a passageway extending from the central bore toward the cutting face, such that excessive wear of the cutting face opens the passageway to allow the drilling fluid to flow therethrough, thereby reducing a surface pressure of the drilling fluid and indicating excessive wear of the bit. The passageway may extend to adjacent, or within one half inch or three inches of, the cutting face, such that excessive wear opens the passageway to the cutting face. In some cases, the passageway may actually extend through the cutting face with a plug inserted into the passageway at the cutting face to prevent the drilling fluid from exiting the passageway absent wear of the bit.
