An electric hand tool apparatus ( 1 ) for driving a drill-like tool, which carries out an at least partial rotational movement, has within a housing ( 2 ), an electric motor ( 4 ) without or free of collector and slip ring, the rpm of which can be controlled by motor control electronics ( 3 ), wherein an rpm-dependent clutch ( 5 ) for transferring the torque is disposed in a force transfer path from the electric motor ( 4 ) to a transmission ( 6 ). Optionally, to prevent an excessively high twisting of the housing ( 2 ), a sensor ( 7 ) is evaluated and the rpm of the electric motor ( 4 ) is reduced in order to sever the transfer of force by the rpm-dependent clutch ( 5 ).
