Abstract: In a device for rough turning and shaft turning of a workpiece, a cutting insert is provided with a main cutting edge followed by an auxiliary cutting edge. The main cutting edge is divided into a first main cutting edge functioning as a rough cutter followed by a second main cutting edge performing rough smoothing and then by the auxiliary cutting edge which provides the final smoothing. The first main cutting edge is set at a greater angle to the axis of the workpiece than the second main cutting edge which, in turn, is set at a greater angle to the axis of the workpiece than the auxiliary cutting edge.

Abstract: A device for the internal deburring of a pipe or shaped tubular member, such as for removing the inwardly projecting portion of an axially extending seam, includes a support body elongated in the axial direction of the pipe. A cutting ring is clamped externally to the support body adjacent one of its ends. The cutting ring has an axis extending transversely of the axis of the pipe. The support body is constructed so that the cutting ring can turn in the rotational direction around the axis of the pipe.

Abstract: A material removing tool wherein a substantially plate-like support of steel carries at least one annular cutter which is made of a harder metallic material capable of being soldered to the material of the support. The support has a centrally extending projection which is received in a complementary opening of the cutter, and the cutter has two or more substantially radially extending webs in register with grooves which weaken the cutter in the regions of the webs so that at least one of the webs breaks in response to soldering of the cutter to the support. The breaking of one or more webs is promoted by proper selection of the thermal expansion coefficients of the materials of the support and cutter. The provision of breaks in the webs, either as a result of bonding or as a result of utilization of cutter sections, ensures that each cutter section between two neighboring webs can be put to use independently of the condition of the other section or sections.
