Hob cutter arrangement

A hob cutter arrangement with a tool body which is at least partially formed from a cutting material, and which has a continuous axial bore, conical bore sections forming both ends of the axial bore, an end shank body, respectively, at each end of the tool body, adapted for coupling with a hobbing machine, and which has a conical section inserted fittingly into the conical bore section, and which has a radial flange which is configured to be placed against an end face of the tool body when the conical section is seated in the conical bore section, and which the end shank body has a shaft section opposite the conical section for clamping in a machine tool, with an axle connecting the end shank bodies, which is adapted to clamp the end shank bodies together and bias the conical sections into the conical bore sections, and which is provided with at least partly threaded end sections,

• wherein at least one of the end shank bodies are provided with axial blind holes for insertion of the end sections of the axle,
• wherein the axle has a central section with an outer diameter smaller than the inner diameter of the central section of the tool body, and
• at least one circumferential coupling between the axle and the tool body is located in the central section of the tool body, the coupling includes a positive connection with a longitudinal groove in an inner surface of the tool body and a longitudinal ridge on a surface of the axle.
