摘要： A drilling and chiseling bit includes a base member (1) having an axis extending in the drilling and chiseling direction. The base member has an end face disposed transversely of the axis, with a recess (3) extending in the axially direction inwardly from the end face. A cutting member (2) is secured in the recess by a soldered joint. At least one of the base member and cutting member is formed to prevent the development of shear stress peaks in the end regions of the recess extending transversely of the axial direction. To prevent the shear stress peaks, relief notches or recesses can be provided in the base member (1) or the soldered joint (4) can have a variable thickness in the axial direction increasing towards the opposite ends of the recess.

摘要： A rock drill has an axially extending shank (1) with a drill head (2) on one end. The drill head (2) has an end face (3) with a cutting blade (4) and cutting pins (5) extending outwardly from the end face in the drilling direction. The cutting blade (4) extends diametrically across the end face and projects radially outwardly from the drill head (2) and axially outwardly from the end face (3). The cutting pins (5) are arranged on a diameter of the drill head which forms an acute angle relative to the cutting blade (4). Due to the acute angle between the cutting pins and the diametrically arranged cutting blade, removal grooves extending axially from the end face can be enlarged.

摘要： A self-drilling connecting unit includes a shaft and a platelet-like cutting tool attachable to the shaft in a form- and/or force-fitted manner. The platelet-like cutting tool has a platelet-like protrusion lying in the plane of the cutting tool in its end region facing the shaft. The end region of the shaft, which bears the cutting tool, has a central opening. The protrusion of the cutting tool is insertable into the opening of the shaft and is braced by a pressure seat in the opening against two diametrically opposed boundaries of the inner wall of the opening whereby a sufficient mount and an exactly axis-parallel alignment of the cutting tool against the shaft are provided.

摘要： Boring apparatus for forming a generally horizontal underground passage for a utility conduit or the like that includes a tool head with elongated body structure and a cutting face of ellipto-conical form at one end of the elongated body structure. The cutting face has a major axis and a minor axis and cutting bit structure is fixed to and projects forwardly from the cutting face and extends substantially the full width of the cutting face generally along the major axis. The tool head also includes coupling structure for attaching the tool head to a drill string such that the cutting tool face is offset from the drill string axis. Structure in the cutting face defines a cutting fluid orifice adjacent the cutting bit structure for directing a high velocity jet of cutting fluid forwardly of the cutting tool face. The tool body is adapted to be advanced and concurrently driven in rotation to move the cutting face in orbital boring action about the drill string axis to bore an underground passage and to be advanced without rotation to produce a change in direction of the underground passage in the direction of offset from the drill string axis.

摘要： A drill bit blade for masonry and rock drills incudes first and second lateral side surfaces, first and second flank side surfaces, and converging first and second tip face surfaces. A first lateral cutting edge is defined by the intersection of the first tip face surface with the first lateral side surface, and a first lateral trailing edge is defined by the intersection of the first tip face surface with the second lateral side surface. A first lateral cutting edge is defined by the intersection of the first tip face surface with the second lateral side surface, and a second lateral trailing edge is defined by the intersection of the second tip face surface with the first lateral side surface. A chisel edge is defined at the converging intersection of the first and second tip face surfaces. A first notch is formed in the first lateral trailing edge and second lateral cutting edge at one end of the chisel edge, and a second notch is formed in the second lateral trailing edge and first lateral cutting edge at the other end of the chisel edge. In addition, notches are also formed in the first and second lateral cutting edges to divide the lateral cutting edges into cutting edge segments.

摘要： A rock drill for rotary and percussive stressing exhibits equally good or improved transport characteristics of driling dust for a smaller transport groove as compared with prior rock drills. In order to achieve this, a main transport groove having longitudinal profiles is formed, with an interrupted secondary transport groove integrated in the main transport groove, the transport ribs of which exhibit a greater angle of twist than the angle of twist of the main transport groove.
