1. A portable electric power tool, comprising:
- a housing with a connection terminal for connection of a voltage supply source;
an electric motor;
an onboard operation control unit;
a radio communication device for communicating operation data and operation result data between the power tool and a stationary data processing unit; and
back-up voltage accumulating device which is provided onboard the power tool to keep up continuously a voltage supply to the operation control unit and the radio communication device at occurring disconnections of the voltage supply source, so as to reduce delay for reassuming an operation condition of the tool after re-connection of the voltage supply source.
