  • the known screw attachment leads to problems because the depth stop sleeve rotates with the output part.
  • the depth stop sleeve is rotatably mounted on the depth stop holder of the depth adjustment device by means of a rotary bearing comprising a roller bearing, in particular a ball bearing.
  • the approach according to the invention is that the depth stop sleeve can rotate freely with respect to the drive side and output side.
  • the depth stop sleeve can, so to speak, stop or stand still when screwing in screws on the workpiece, while the driven part on which the screwing tool, usually a screwdriver bit, is arranged, continues to turn in order to screw the screw into the workpiece to the desired extent.
  • roller bearing for example a ball bearing or roller bearing
  • the roller bearing has low friction so that hardly any drive torques from the drive side (from the screwdriver) act on the depth stop sleeve.
  • the depth stop sleeve is preferably exchangeable on the screw attachment.

  • the depth stop holder expediently has a pivot bearing receptacle for the pivot bearing.
  • the pivot bearing receptacle is advantageously formed by a step or comprises a step.
  • the pivot bearing can thus be accommodated in a space-saving manner.
