  • Patent number: 8978786
    Abstract: 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.

  • Patent number: 8356398
    Abstract: An earth-boring bit comprising a bit body is configured at its upper end for connection into a drillstring. A fixed blade depends axially downwardly from the bit body. An axially extending slot is formed in the bit body adjacent the fixed blade. A bit leg is received and retained in the slot by engagement between the slot and correspondingly shaped bit leg, wherein the bit leg cannot be removed from the slot except by axial movement relative to the bit body. A rolling cutter is secured to the bit leg at its lower extent. A fastener secures the bit leg against movement relative to the bit body and extends through oblong apertures in the bit leg and into the bit body, the bit leg can be moved axially relative to the bit body to adjust the projection of the rolling cutter relative to the fixed blade.

  • Patent number: 8141664
    Abstract: A hybrid drill bit having at least two rolling cutters, each rotatable around an axis of rotation, at least one of the rolling cutters having a high pin angle, and at least one fixed blade. The pin angle can encompass pin angles above 39 degrees to less than 393 degrees. The drill bit can allow the rolling cutters to engage a shoulder portion and/or gage portion of the bit profile and assist the fixed blade(s) in these areas. The at least two rolling cutters can be disposed at different pin angles.
