A driver drill may have two battery attachment portions to which two rechargeable batteries can be attached. Therefore, the driver drill can meet a need for an increased voltage or an increased discharge capacity. Further, the two battery attachment portions may be constructed as slide-fitting battery attachment portions. A combined gravity center of the rechargeable batteries attached to the first and second battery attachment portions may be positioned on a vertical line through a gravity center of a tool main body in a condition in which the two rechargeable batteries are detached therefrom. |
