A control unit is adapted to perform a process related to an electric power tool, based on sound input to a microphone. The control unit performs a process related to the electric power tool, based on a result of subjecting input sound to a sound recognition process or a result of subjecting the sound to sound analysis. When a user operation switch is in an on state, the control unit does not perform a sound recognition process, and, when the user operation switch is in an off state, the control unit performs a sound recognition process. Further, when the electric power tool is not in a state of being gripped by the user, the control unit does not perform a sound recognition process, and, when the electric power tool is in a state of being gripped by the user, the control unit performs a sound recognition process.

Electric tool

An object of the present invention is to provide a tool system allowing a tool to be controlled on a work object basis before the work is started. A tool system includes a portable tool and an identification unit. The tool includes a driving unit to operate with power supplied from a battery pack. The identification unit identifies, by a contactless method, a current work object, to which the tool is set in place, out of a plurality of work objects.
