A sub-surface borehole underreamer is disclosed having freely rotatable precessing diamond cutters attached to extendable arms connected to the body of the underreamer. The diamond cutting face is skewed to a degree that tangential contact of the peripheral edge of the diamond cutter causes the rotating cutter to precess as the underreamer body is rotated by a drill string.

A rotary drill bit comprising a bit body having a plurality of drag cutting elements mounted on the bottom thereof. Each cutting element has a portion projecting down below the bit body and forward generally in the direction of rotation of the bit. This portion presents a leading face and a trailing face which converge at an acute angle to form a cutting edge. Each element is positioned on the bit body such that its leading and trailing faces present a positive rake angle and back clearance, respectively, to the surface of the well bore formation for improved cutting action. The bit body has an exit port at the bottom thereof for flow of drilling fluid under pressure, and sets of first and second generally parallel ridges defining watercourses extending from the exit port to the periphery of the bit. The cutting elements are mounted on the second or trailing ridge, and extend toward but stop short of the first or leading ridge. The leading face and cutting edge of each element thus extend into the watercourse and are cooled and cleaned by the drilling fluid.

Drag-type drilling bits are disclosed which have at least one blade and a plurality of fluid flow channels incorporated in the blade for conducting drilling fluid or drilling mud from the hollow interior of the bit to discharge or ejection ports located in the front cutting edge of the blade. Rods of diamonds or of like "hard" cutter insert materials are incorporated in the blade in such a configuration that as the blade wears away or erodes and small pieces of diamonds are lost during drilling, more diamonds are exposed to the formation for drilling. During erosion or wear of the blades, the fluid discharge ports continue to operate to eject drilling fluid adjacent to substantially each diamond rod, whereby the flushing away of cuttings and cooling of the diamonds is greatly improved. In some embodiments of the invention rods of alternating hard and soft materials are also disposed substantially parallel with the diamond or like "hard" cutter insert rods. When the soft material of the rods is exposed for drilling the formation, kerfs are formed which are thereafter "chipped away" by the subsequently exposed hard material of the rods.

A fishtail type drag bit having abradable cutter blades attached to a body of the bit is disclosed. A multiplicity of axially aligned tubes are welded together to form a blade each blade being sustantially parallel with an axis of the bit body. Each tube of the blade contains an annulus of a diamond cutter material matrix. The center of the annulus forms a fluid conduit that communicates with a fluid plenum chamber formed by the body of the bit. The cutting edge of the diamond matrix therefore, is always immediately adjacent the fluid nozzle regardless of the degree of blade erosion during operation of the bit in a subterranean formation.

Methods and apparatus are disclosed for the rapid and efficient drilling of oil well and other types of bore holes through tough abrasive underground formations, which methods and apparatus utilize high drag intermittent contact and cooling techniques to provide good rates of penetration with low wear and heat deterioration on the drilling tools.

A fishtail type drag bit is disclosed consisting of multiple blades, each blade forming radially disposed grooves. Each groove contains equidistantly spaced diamond cutters along its length. The cutters are additionally oriented at a negative rake angle with respect to a borehole bottom. The vertical alignment of the diamond cutters paralleling an axis of the bit are staggered to destroy kerfs which remain in the formation from preceding eroded rows of diamond cutters as the bit works in the borehole.

A drag type drilling bit having a plurality of radially disposed raised lands on the bit face is disclosed. A multiplicity of polycrystalline diamond compacts are strategically disposed on the raised lands. At least a pair of lands are joined at the outside periphery of the bit thereby closing the valley formed between the lands, thus forming a plenum for drilling fluid that exits the bit interior through ports or nozzles communicating therewith. Highly turbulent fluid confined in the plenum continually scrubs and scavenges the hole bottom while simultaneously and uniformly cooling and cleaning the PDC cutters during operation of the bit in a borehole.

Drilling bits are disclosed which are particularly efficient drilling devices when used in soft plastic underground formations which normally are difficult or impossible to drill with conventional drilling bits. The bits of this invention are characterized by having relief openings formed in the individual cutting elements to provide extrusion of the soft formation face into removable chips.

A bearing for a rotary cone for a rock bit is disclosed. The bearing consists of a multiplicity of small synthetic diamond particles nested within a matrix base, each with an exposed flattened surface to form the bearing. The diamond particles are strategically positioned on a bearing surface and secured within the matrix base. A substantially identical synthetic diamond bearing is concentrically positioned adjacent to the first bearing to form the bearing package.

An oil well drilling bit is disclosed of the type utilizing hard metal inserts in the rolling cutters wherein each row of inserts on each cutter is located thereon in a sinusoidal or varying pattern rather than the strictly circumferential pattern of the prior art.
