  • Patent number: 10253571
    Abstract: A drill bit includes cutters rotatively mounted thereon. A bore is provided either directly in the drill bit or in a sleeve which is mounted on the drill bit. The bore includes a female screw thread, a circumferential groove, and one or more bearing surfaces. A cutter with a hardened table has a generally cylindrical body with a male screw thread, a circumferential groove, and one or more bearing surfaces. The cutter is engaged with the threads of the bore and then advanced until the male screw threads pass beyond the female screw threads. When the cutter is fully installed, the circumferential grooves provide relief for the screw threads so that the cutter can freely rotate within the bore.

  • Patent number: 9469959
    Abstract: The device is a Full Displacement Pile Tip (FDPT) with a sacrificial drill bit that is connected to a steel pipe, where the tip comprises at least four flanges or fish tails at the cutting edge extending from a conical, dome-like bottom, and integrally connected to the cutting teeth along the tip's axial shaft. The purpose of the FDPT is allow a steel pier to be screwed into the ground to serve as a foundation for a structure. This is a single operation where the FDPT and pipe remain in the ground. There is no removal of FDPT, minimal pouring of concrete, and there is minimal soil spoilage. A smaller drilling rig can be employed to save operating costs.

    Abstract: A device for drilling deep holes in the ground has at least two axial drill bits and an equal number of plates each having three shafts axially interconnecting the plates. Two of the shafts are rigidly attached to both plates and the third shaft is pivotably attached to both plates. The two rigid shafts are separable from the upper plate by pulling a locking pin separating a telescopic head of each shaft from the plate. At the separation, the shafts are telescopically shortened by springs and the drilling liquid is automatically shut off to the worn-out drill bit and opened to the new drill bit. The remaining third shaft eccentrically interconnects the plates, whereby the lower worn-out drill bit, at rotation, wears a semicircular evacuation pocket in the wall of the hole. The third shaft is successively pivoted outwards until it forms an angle of e.g. 80.degree. with the axis of the hole. An axle pin having rectangular cross-section retains the upper end of the third shaft via a sleeve with a slit.

The drill bit has a cutting face comprised of a plurality of radially spaced apart stud assemblies, each received within a socket. A polycrystalline diamond disc forms one end of the stud assembly. The socket is in the form of a counterbore extending angularly into the bit body so that when a marginal end of the stud assembly is forced into a socket, a portion of the face of the diamond disc extends below the bottom of the bit body for engagement with the bottom of a borehole. A passageway communicates with the rear of the counterbore and extends back to a surface of the bit. Fluid pressure is effected within the passageway, thereby developing sufficient pressure differential across the stud assembly to cause the stud assembly to move respective to the socket.
