1. A hand-held power tool, comprising:
a housing;
an output spindle;
a drive unit configured to drive the output spindle, the drive unit being arranged in the housing; and
an annular friction element arranged in the housing,
wherein the drive unit includes a catch mechanism that has a first crown disk connected to the output spindle for conjoint rotation, and a second crown disk arranged in the housing for conjoint rotation,
wherein, in a first position, the first crown disk and the second crown disk bear against one another,
wherein, in a second position, the second crown disk is arranged so as to be spaced apart from the first crown disk along an axis of rotation of the output spindle, and
wherein the annular friction element is arranged without friction in the first position and generates a predefined frictional force between the first crown disk and the second crown disk in the second position.
