Abstract
An electric torque delivering impulse tool includes a housing with a front end and a back end, an electric torque delivering motor with a rotor that is arranged to rotate with respect to a stator, an output shaft arranged at the front end of the housing, and a pulse unit intermittently coupling the motor to the output shaft, wherein the pulse unit includes an inertia drive member that is connected to the rotor. The rotor and the inertia drive member are rigidly assembled to each other without play so as to form one integrated rotatable structure which is mounted as one single unit inside the housing.
