    摘要: A flat cutter bit for engaging an earth strata material includes a non-rotatable shank portion, a head portion integrally formed with the non-rotatable shank portion and including a tip region distal from the non-rotatable shank portion, and a cutting insert mounted at the tip region of the head portion. The cutting insert includes a body having an angled leading face, a top surface having a relief surface, a T-land surface extending between the angled leading face and the relief surface of the top surface and a cutting edge formed at the intersection of the T-land surface and the relief surface of the top surface.

    摘要: An improved diamond coated tip on a bit/holder for road milling operations has a broadened tip base that provides cutting overlap with adjacent bit/holders resulting in a micro milling type surface when utilizing a regular ⅝ inch center-to-center drum. The ballistic insert of this design will cut asphalt as well as shallow depth concrete. Prior art design diamond tool can only cut asphalt. Tip breakage occurs when prior art diamond tool scratch concrete. Scratching concrete means engaging the top surface of concrete roadway.

    摘要: A non-rotatable cutter bit for mining and construction operations having a central longitudinal axis extending therethrough includes an insert at one end. The insert has a central longitudinal axis and the apex is offset from the central longitudinal axis to provide an elongated rake face. With the insert mounted within the cutter body, the central longitudinal axis of the cutter body intersects with the apex such that the cutter body may be easily exchanged with conventional cutter bodies. The insert may also be mounted directly to the body without using an insert holder. The insert also has applications in oil and gas drilling operations.

    摘要: A tip for a pick tool, comprising a polycrystalline diamond (PCD) structure joined to a substrate body. The PCD structure has a strike surface including an apex opposite a boundary with the substrate body. At least an outer volume of the PCD as structure contains filler material between diamond grains, the content of the filler material being more than 5 weight percent of the PCD material in the outer volume. The outer volume is proximate at least an area of the strike surface including the apex, and the thickness of the PCD structure between the apex and the boundary with the substrate body is at least 2.5 mm.
