Abstract
A hand-held power tool, in particular in the form of a hammer drill or an impact screwdriver, is disclosed. The tool has a tool receptacle attached to an output shaft for receiving a tool, where the output shaft may be set into a rotating and partially percussive motion by a drive shaft and a tangential striking mechanism. The tangential striking mechanism has an anvil allocated to the output shaft and a hammer allocated to the drive shaft. The hammer can be moved axially under the application of the force of a spring and a sliding block guide, and can be struck against the anvil with the rotation of the same. The sliding block guide has a helical control contour which has a first slope in a first section and a second slope in a second section, where the first and second slopes are different.
