The hand-held drilling and/or screwing implement has a housing with a handle, an electrical driving motor, a carbon brush holder ring and a switching body, which interacts rotationally locked with the carbon brush holder ring. At the carbon brush holder ring, two carbon brush holders are disposed opposite to one another and the switching body has an actuating element, which is disposed on the side opposite to the handle. With the help of an axial positive connection, the carbon brush holder ring can be fastened to the stator, so that it can be inserted together with the stator as a unit in the housing.
