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.

摘要： An earth boring drill bit designed for a specific performance, within a finished product tolerance, using components built to a looser manufacturing tolerance. The bit may be assembled by selecting a leg from a plurality of pre-manufactured legs; selecting a bit body from a plurality of pre-manufactured bit bodies, the bit body having a slot for receiving the leg; placing the leg within the slot; and fixing the leg within the slot within the finished product tolerance by placing one or more shims between the leg and the slot. The shims may be used to adjust an axial position, a radial position, and/or a circumferential position of the leg with respect to the slot. The leg and the bit body may be selected, or produced, to ensure the bit will not meet the specification, given the manufacturing tolerance, without the shims.

摘要： A bit body is configured at its upper extent for connection into a drillstring. At least one fixed blade extends downwardly from the bit body, and has a radially outermost gage surface. A plurality of fixed cutting elements is secured to the fixed blade, preferably in a row at its rotationally leading edge. At least one bit leg is secured to the bit body and a rolling cutter is mounted for rotation on the bit leg. At least one stabilizer pad is disposed between the bit leg and the fixed blade, the stabilizer pad extending radially outward to substantially the gage surface. The radially outermost gage surface of each blade can extend axially downward parallel to the bit axis or angled (non-parallel), spirally or helically, relative to the bit axis.
