Abstract: A screwing tool has a driving portion, an output portion, and a switching ring of a freewheel lock, the switching ring being disposed axially between the driving portion and the output portion, and the freewheel lock being able to be brought, by rotation of the switching ring in an azimuthal switching direction, into a freewheel position, in which the output portion can be rotated relative to the driving portion in a freewheel direction. In order to enable a “quick screwing function” by means of the screwing tool, the switching ring can be rotated in the freewheel direction in question without limitation, which is achieved by virtue of the fact that the switching direction corresponds to the freewheel direction.
