Abstract

A power tool includes a housing in which a drive unit is arranged, and a tool holder for the detachable holding of a tool insert. The tool insert is configured to be driven percussively and/or rotationally. A sensor unit is configured to detect at least one movement variable, and electronics are configured to control or regulate the power tool. The electronics have a percussion detection unit configured to determine a percussion mode based on at least one movement variable and/or a rotation detection unit configured to determine a rotation of the housing. The electronics control the drive unit based on the determined percussion mode and/or the determined rotation of the housing. The electronics have at least two parameter sets for the percussion detection unit and/or at least two parameter sets for the rotation detection unit. The electronics are configured to select one of the at least two parameter sets.
