摘要： An improved drill bit for the mining field for use as a roof drill, tunnel drill, rock boring and highway construction, both as a rotary and a rotary percussion drill, which includes a drill head with a diametrical slot positioning a brazed cutting blade, the head having a male drive shank to interfit with a female driver tube and having axial passages leading to chip slash pockets for removal of chips either by incoming pressure fluid or outgoing suctioning action. The supporting prongs of the drill head on opposite sides and at opposite ends of the blade are narrowed in thickness to provide chip clearance and designed to overlap centrally to provide tip strength and central support for the blade.

摘要： A cutting tool for a pneumatic hammer operative at the bottom of a hole comprising a head for supporting cutting bits and a tail of reduced diameter extending from the head and provided with grooves forming alternating asymmetrical teeth engageable in symmetrical grooves provided in the interior of the front cylinder of the hammer. Each tooth of the cutting tool has a working flank in contact with the hammer during drilling which is of greater height than the other flank of the tooth so that each asymmetrical tooth can define in the symmetrical groove of the hammer an escape channel for compressed air from the hammer.

摘要： An auger or boring head, especially for horizontal rock and earth drilling having a circular ring of circumferentially spaced tool bits or teeth, a plurality of spokes or fins with leading ends carrying tool bits or cutting teeth in convex curved or arcuate contours from a central cutting point forwardly of the ring to the periphery of the ring. The cutting teeth on the ring project radially outward from the periphery thereof and are tilted forwardly in the direction of rotation of the auger head. The cutting teeth on the spokes or fins project forwardly, are tilted toward the direction of rotation of the head and are also tilted backwardly to present the tip end of each tooth in a straight forward direction to the surface which it is cutting. In addition, the teeth are staggered so that successive teeth will not have the same cutting track. A head or socket is provided in the center of the auger head for connection to a drill rod or stem. Large open areas are provided through the ring between the spokes or fins, and the earth or rock cut by the head is free to flow through these spaces to a spiral conveyor which preferably has it leading edge behind one of the spokes or fins.

摘要： An erosion bit for earth-drilling operations having a first nozzle system open for conducting drilling fluid and a second nozzle system closed by a pressure-sensitive closure means. Means are provided for plugging the first nozzle system and for actuating the pressure-sensitive closure means to open the second nozzle system. Drilling fluid can initially be flowed through the first nozzle system until the nozzles become eroded and then through the second nozzle system.

摘要： A new and improved drill bit for connection on a drill string has a hollow tubular body with an end cutting face and an exterior peripheral stabilizer surface with cylindrical sintered carbide inserts positioned therein. Nozzle passages extend from the interior of the bit body through the cutting face, preferably at an angle of about 10.degree.-25.degree. relative to the longitudinal axis of the body, and consist of a passage in the bit body and a removable and interchangeable nozzle member. The nozzle member is secured in place either by peripheral grooves and snap rings or aligned smaller passages in the nozzle member and the bit body having a retaining pin positioned therein. The cutting face preferably has a plurality of recesses therein which receive, by an interference fit, a plurality of cutting elements of the type known as STRATAPAX, consisting of a cylindrical stud having an angular supporting surface with a cutting disc bonded thereon consisting of sintered carbide having a cutting surface of polycrystalline diamond. The studs of the cutting element may have a groove along one side which aligns with a small recess along the side of the cutting element recess to receive a metal pin operable to secure the cutting element in place and against twisting. Additionally, an offset counterbore may be provided at the top of the cutting element recesses which provide for stress relief of the cutting elements during cutting operation.

摘要： A diamond studded insert drag bit is disclosed having a multiplicity of individual diamond insert cutter blanks inserted in the face of the bit. The diamond insert blanks are so positioned to maximize penetration of the bit in a borehole. The bit further includes fluid passages strategically located in the bit face to provide uniform flow, cooling and continuous cleaning of each of the diamond cutter insert blanks. The fluid passages are so sized to cause minimum bit pressure drop. Bits with minimum pressure losses from fluid flow are best suited for positive displacement mud motors that cannot tolerate downstream pressures in excess of 50 to 500 pounds per square inch.
摘要翻译：公开了一种具有插入钻头表面的多个单独的金刚石刀片切割器坯料的镶嵌钻石镶嵌钻头。金刚石刀片坯料被定位成使钻头在钻孔中的穿透最大化。钻头还包括策略性地位于钻头面中的流体通道，以提供均匀的流动，冷却和连续清洁每个金刚石切割刀片坯料。流体通道的大小适于产生最小的压力降。来自流体流动的最小压力损失的钻头最适合于不能承受超过50至500磅/平方英寸的下游压力的正排量泥浆马达。
