摘要： In one aspect of the present invention, a drill bit has an axis of rotation and a working face with a plurality of blades extending outwardly from a bit body. The blades form in part an inverted conical region and a plurality of cutters with a cutting surface are arrayed along the blades. A jack element is coaxial with the axis of rotation and extend within the conical region within a range defined by the cutting surface of at least one cutter.

摘要： In one aspect of the invention a drill bit assembly has a body portion intermediate a shank portion and a working portion, the working portion having at least one cutting element. A shaft is supported by the body portion and extends beyond the working portion. The shaft also has a distal end that is rotationally isolated from the body portion. In another aspect of the invention, a method for steering a downhole tool string has the following steps: providing a drill bit assembly attached to an end of the tool string disposed within a bore hole; providing a shaft extending beyond a working portion of the assembly; engaging a subterranean formation with a distal end of the shaft; and angling the drill bit assembly with the shaft along a desired drilling trajectory.

摘要： Pick tool assemblies for use with formation degradation machines, such as road milling, mining, trenching or drilling machines, may be disposed on rotatable drums, wheels, continuous chains, drill bits or the like and brought into engagement with such formations as rock, asphalt, coal or concrete to break up or otherwise degrade the formations. Such pick tool assemblies may comprise a shank comprising a forward end and a rearward end wherein the rearward end may be formed for retention in a bore of a block attached to a driving mechanism and the forward end may comprise a body detachably and nonrotatably fastened thereto. Further, an impact tip may be bonded opposite the rearward end.
