Abstract
In a hand-guided percussion drilling machine an arresting coupling non-rotatably coupling a drilling spindle relative to a machine housing is arranged on an intermediate shaft rotatably connected with the drilling spindle and extending parallel to and at a radial distance from the drilling spindle and at a radial distance from the motor shaft, wherein the arresting coupling openings during a torque transmission from a drive motor to a tool holder in one direction and closes during a torque transmission from the tool holder in an opposite direction.
