A power tool including: a housing configured to support an end bit, a motor accommodated in the housing, a transmission mechanism, a trigger switch, a load judging unit, and a motor stop control unit. The transmission mechanism transmits a rotational force of the motor to the end bit. The trigger switch is configured to switch between instructions to the motor. The instructions include a rotation instruction for providing a rotation state of the motor and a stopping instruction for providing a stopping state of the motor. The load judging unit judges whether or not a load is applied to the end bit during rotation of the motor. The motor stop control unit stops the rotation of the motor irrespective of the instructions of the trigger switch when the load judging unit judges that no load is applied to the end bit and a period of a non-load state exceeds a predetermined time period.
