Abstract

A hand-held power tool, in particular an impact drill, is disclosed. The hand-held power tool includes a housing in which a drive unit for driving an output spindle is arranged. A catch mechanism is associated with the drive unit. The catch mechanism has a first crown disk which is connected to the output spindle for conjoint rotation, and a second crown disk which is arranged in the housing for conjoint rotation. In a first position, the first and second crown disks contact each other via associated catch geometries. In a second position, the second crown disk is arranged spaced apart from the first crown disk along a rotation axis of the output spindle. An annular friction element is arranged without friction in the first position, and generates a specified frictional force between the first and second crown disk in the second position.
