Abstract

A hand tool is disclosed, comprising a housing, a motor shaft being coupled to a drive motor, a working spindle configured for being driven rotatingly oscillatingly about its longitudinal axis, and a coupling element being driven rotatingly by the motor shaft and having a closed guide surface that revolves around the motor shaft. The guide surface is coupled, via transmission means, to at least one driver for driving the latter. The at least one driver is arranged movably relative to the working spindle and engages the working spindle at a circumferential region thereof for driving the latter rotatingly oscillatingly.
