Abstract
A screwing tool includes a tool head and a tool shaft having an external thread. A first support section is disposed between the tool head and the external thread, and a second support section is disposed between the external thread and a free end of the tool shaft. The second support section has radially outwardly projecting supporting elements that are disposed at a distance from each other in the circumferential direction.

A screwing tool comprising a tool head and a tool shaft having an external thread, a first support section disposed between the tool head and the external thread and a second support section disposed between the external thread and a free end of the tool shaft, wherein the second support section comprises radially outwardly projecting supporting elements that are disposed at a distance from each other in a circumferential direction, each radially outwardly projecting supporting element having a contact surface shaped as a cylindrical segment, and wherein disposed in the circumferential direction between the radially outwardly projecting supporting elements are recesses having outside dimensions that are smaller than those of the radially outwardly projecting supporting elements such that each of the recesses do not extend beyond the second support section.
A tool assembly including a screwing tool and a tool holder, the tool holder configured and arranged for engagement with the screwing tool, the tool assembly comprising:
- a screwing tool having a tool head and a tool shaft having an external thread, a first support section disposed between the tool head and the external thread and a second support section disposed between the external thread and a free end of the tool shaft, wherein the second support section comprises radially outwardly projecting supporting elements that are disposed at a distance from each other in a circumferential direction, each radially outwardly projecting supporting element having a contact surface shaped as a cylindrical segment, and wherein disposed in the circumferential direction between the radially outwardly projecting supporting elements are recesses having outside dimensions that are smaller than those of the radially outwardly projecting supporting elements such that each of the recesses do not extend beyond the second support section;
- and
- a tool holder including a receiving opening having an internal thread, a first mounting section disposed between a front face side of the tool holder and the internal thread and an inside second mounting section following the internal thread, wherein the second mounting section comprises radially inwardly projecting mounting elements that are disposed at a distance from each other and configured and arranged to support the tool shaft when the tool shaft is engaged within the tool holder, wherein disposed in a circumferential direction between the radially inwardly projecting mounting elements are recesses spaced from the internal thread, the recesses having outside dimensions that are larger than those of the radially inwardly projecting mounting elements and wherein each of the radially inwardly projecting mounting elements has a mounting surface shaped as a cylindrical segment configured and arranged for contacting one of the contact surfaces shaped as cylindrical segments of the radially outwardly projecting supporting elements of the screwing tool when the screwing tool is engaged in the receiving opening.
A tool holder configured and arranged for engagement with a screwing tool, the tool holder comprising:
- a receiving opening having an internal thread, an internal first mounting section disposed between a front face side of the tool holder and the internal thread and an internal second mounting section following the internal thread, the internal first mounting section, the internal thread, and the internal second mounting section formed as one piece, wherein the internal second mounting section comprises radially inwardly projecting mounting elements that are disposed at a distance from each other, wherein disposed in a circumferential direction between the radially inwardly projecting mounting elements are recesses spaced from the internal thread, the recesses having outside dimensions that are larger than those of the radially inwardly projecting mounting elements.
