For the purposes of assembling an electric tool, and especially an electric hand tool such as, for example, a hand drill, a grinder or a sabre saw, it is proposed to use modular components that are to be axially inserted into and connected with each other. The components comprise a self-contained electric driving motor that supports the rotor shaft in a centered position by means of end shields on both sides that are rigidly fixed to the stator, a self-contained gearing head that is fixed to the motor, and at least a partially tubular, single piece main housing that accommodates the driving motor and the gearing head, an electric circuitry module inserted into the main housing, and a rear cover for the housing.
