| 20090071723 | DRILL WITH A CENTERING DRILL INSERT, AND A METHOD OF USING A DRILL WITH A CENTERING DRILL INSERT, AND THE INSERT THEREFOR - Drill with a centering drill insert, and a method of using a drill with a centering drill insert, and the insert therefor. The abstract of the disclosure is submitted herewith as required by 37 C.F.R. §1.72(b). As stated in 37 C.F.R. §1.72(b): A brief abstract of the technical disclosure in the specification must commence on a separate sheet, preferably following the claims, under the heading “Abstract of the Disclosure.” The purpose of the abstract is to enable the Patent and Trademark Office and the public generally to determine quickly from a cursory inspection the nature and gist of the technical disclosure. The abstract shall not be used for interpreting the scope of the claims. Therefore, any statements made relating to the abstract are not intended to limit the claims in any manner and should not be interpreted as limiting the claims in any manner. | 03-19-2009 |
| 20090260891 | Method of Mechanized Construction for Earth Wire Under-Bracing and Extendable Excavating Unit for Auger Crane - A method of mechanized construction has developed for installing an earth wire under-bracing by using an auger crane and adjustable excavating unit with an auger crane. The extendable excavating unit is mounted to the lower end of an auger shaft of the auger crane and excavation teeth extendable and retractable are mounted to the excavating unit, thereby allowing excavation of a burial hole suitable to the size of the earth wire under-bracing. Whether it is needed to bury the earth wire under-bracing having a larger diameter than the diameter of excavation existing on the auger crane, or bury small-sized earth wire under-bracing, a method for mechanized construction of the earth wire under-bracing is enabled without difficulty by using an auger crane and adjustable excavating unit. | 10-22-2009 |
| 20090260892 | DRILL ROD, DRILL BIT, AND DRILLING TOOL - A drill rod having a fitting portion protruding toward the distal end and of the drill rod and extending along a first axial line, wherein the fitting portion includes: a parallel male thread portion in which a minimum distance from the first axial line in a cross-section perpendicular to the first axial line is constant; and a male thread ending portion which is continuous with a proximal end of the parallel male thread portion, and in which the minimum distance increases as approaching toward a proximal end thereof; wherein the fitting portion is formed such that the minimum distance does not decrease as approaching from a distal end to a proximal end thereof; and the proximal end of the male thread ending portion is positioned on a face where a distance from the first axial line gradually increases as approaching from the parallel male thread to the proximal end of the male thread ending portion. | 10-22-2009 |
| 20090277691 | DRILLING TOOL, IN PARTICULAR SPIRAL DRILL - In a drilling tool, in particular a spiral drill, in particular for drilling rock, comprising a tool-side fastening end, a workpiece-side cutting end and an interposed cutting part comprising at least one main helical groove extending along the cutting part, which is defined by a substantially constant helix pitch, and at least one partially cylindrical and/or partially conical helix web outer face extending along the cutting part, defined by at least one main helical groove, it is provided that a plurality of groove sections are formed in the helix web outer face, which extend transversely to the direction of the pitch of the main helical groove. | 11-12-2009 |
| 20090294181 | BOX GUSSETED EARTH AUGER - A brace or gusset is added to the first and last flight blade of an auger length for stability and reinforcement. The braces are generally box shaped with the flight blade as the box bottom. The brace walls are welded together along with a top panel. The brace is adjacent the auger shaft on one end and complementary shaped on one side to conform to the shape of the flight helix. A deflector is added to the last flight blade to distribute dirt and debris away from the first flight blade on the subsequent auger length. The auger length is reinforced against the twisting torque and compressive forces that occur at the first and last flight blade. | 12-03-2009 |
| 20120181088 | GARDEN AUGER - The present disclosure provides for a garden auger comprising a shank and an auger body. The auger body comprises a leading end and a trailing end including a space therebetween. The auger body is substantially radial including at least two legs connecting the trailing end and the leading end. The leading end has a cutter including a plurality of teeth forming a cutting diameter. The plurality of teeth each have a tip extending from the leading end, wherein the tips form a plane that is substantially perpendicular to an axis of rotation of the garden auger. The auger body is attached to the shank to prevent rotation therebetween. The shank comprises an attachment portion for attachment to a drill motor. | 07-19-2012 |
| 20120205161 | AUGER - The invention relates to an auger having a cutting means for removing ground material and a conveyor flight for conveying the ground material removed by the cutting means, whereby the conveyor flight has several conveyor flight pieces which are arranged along an axial direction of the auger and connected to each other in a detachable manner. Provision is made for a central receiving shaft, on which the cutting means is arranged in a rotationally fixed manner. Furthermore, provision is made for the conveyor flight pieces of the conveyor flight to have a mounting pipe each, which is mounted onto the central receiving shaft, whereby the central receiving shaft projects through the mounting pipe, and for the conveyor flight pieces to be connected in a rotationally fixed manner to the central receiving shaft. | 08-16-2012 |
| 20130319774 | DRILL BIT AND CUTTING HEAD FOR DRILL BIT - The invention provides a cutting head for a drill bit, the cutting head comprising four substantially identically shaped cutting arms extending radially from a common central axial point, each cutting arm comprising a cutting edge extending outwardly and axially backwards from the common central axial point. The cutting edges are equiangularly spaced apart from each other about the central axis of the cutting head. Each cutting arm further comprises a side chamfer extending between its radially outer face and its rotationally trailing side face. | 12-05-2013 |
| 20140246247 | DOWNHOLE DUAL CUTTING REAMER - A downhole dual cutting reamer for bidirectional reaming of a wellbore with a tubular body with two cutting sections between end segments. Each cutting section has a plurality of helical blades separated by a flute, and wherein the helical blades are formed from at least two spiral angled sections connected together, with cutting components on the spiral angled sections. The cutting components can be polydiamond cutter nodes, high strength carbide cutting nodes, and tungsten carbide facing coating. The outer diameter of each cutting section is larger than the outer diameter of each of the end segments. | 09-04-2014 |
| 20140299385 | CUTTERS FORMING A HELIX ORIENTED IN THE DIRECTION OF REAMING - The Smart Reamer® Tool, Apparatus or Method is used to underream an oil or natural gas well while interlinked calipers and calibration sensors simultaneously record data relating to the geometry of the drilling operation (well diameter, diameter of the underreamed zone) and drilling fluid properties (density). Further sensors provide data on the relative position of the cutting and stabilizing blocks. Other sensors measure vibration data. All the sensors are interlinked by means of microprocessors which compare and correlate said data to automatically verify and deliver a desired wellbore diameter without the need to unnecessarily stop drilling or trip out of the hole. | 10-09-2014 |
| 20160032656 | FLUTED WING AUGER - An auger has a substantially conical core, which has an axis and a side centered thereabout. From a substantially flat, substantially circular base of the core at a trailing end of the core, the side tapers to form a diameter smaller than that of the base and on the axis at a leading end of the core. The auger includes a shank centered about the axis and fixed to the base for connecting the auger to a collar and includes at least two wings fixed to the core. The base of the core is perpendicular to the axis and is substantially circular. The wings extend radially from the base and along the tapered side of the core to at least the leading end of the core, wherein the wings are configured such that they wind at least partly around the core axis on the tapered side of the core. | 02-04-2016 |
