摘要： An earth-boring bit has at least one steel tooth with a scoop-shaped profile. The scoop-shaped profile is formed by milling and hardfacing a tooth to have at least one flank with a concave profile. Additionally, the tooth may contain one flank with a concave profile and another with a convex profile. The centerline axis of the tooth may be moved to alter the angle between the flanks and the centerline to vary the manner in which the tooth engages the formation.

摘要： A hole opener having a hybrid reaming section for downhole earth boring operations may include a reamer body having an axis of rotation, an outer periphery, and upper and lower ends, a plurality of rolling cutters coupled to the outer periphery and depending downwardly, the rolling cutters defining a rolling cutter cutting profile having a cutting diameter, a plurality of fixed blade cutters coupled to the outer periphery and defining a fixed blade cutter cutting profile having a cutting diameter, each fixed blade cutter being coupled between adjacent rolling cutters. At least one of the fixed blade cutters may be asymmetrically coupled about the axis. The cutting diameter of the fixed blade cutter cutting profile may be larger than the cutting diameter of the rolling cutter cutting profile. At least a portion of the fixed blade cutter cutting profile may be deeper than the rolling cutter cutting profile.

摘要： Described herein are roller cone drill bits and modified roller cones for use in drilling subterranean earth formations, and more specifically roller cone drill bits and roller cones having optimized spear point designs and blade orientations on at least one of the roller cones for reduced tracking and/or increased drilling performance during bit use. The roller cone drill bits include a bit body with a longitudinal axis, one or more bit legs depending from the body, and at least one roller cone attached to each of the bit legs and able to rotate with respect to the bit body, wherein at least one of the roller cones includes a spear point at the cone apex having two or more cutting blades, the cutting blades being oriented at a variety of non-equal, asymmetric angles about a central cone axis with respect to each other, such that tracking during drilling using the drill bit is minimized or eliminated.

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： An earth boring drill bit that includes a cutting cone with a cutting disk. Compacts are inserted within the disk having a chisel shaped end set flush with the cutting disk periphery. The compact crests and cutting disk periphery form a generally seamless cutting surface. The cutting cone can further include cutting teeth thereon also having flush mounted compacts. The compacts can be made from a material such as cemented carbide, hardfacing, tungsten, tungsten alloys, tungsten carbide and the cutter made from steel.
