    摘要: In one aspect of the invention, a method for drilling a bore hole includes the steps of deploying a drill bit attached to a drill string in a well bore, the drill bit having an axial jack element with a distal end protruding beyond a working face of the drill bit; engaging the distal end of the jack element against the formation such that the formation applies a reaction force on the jack element while the drill string rotates; and applying a force on the jack element that opposes the reaction force such that the jack element vibrates and imposes a resonant frequency into the formation.

    摘要: A high impact resistant tool having a sintered body of diamond or diamond-like particles in a metal matrix bonded to a cemented metal carbide substrate at a non planar interface, interface having at least two circumferentially adjacent faces, outwardly angled from a central axis of the substrate. The sintered body has a thickness of 0.100 to 0.500 inches proximate each face. The sintered body also has a flat working surface, wherein the tool has an angle of 30 to 60 degrees between the flat working surface and each face.
