Dust collection system for power tool
A power tool and a dust collection attachment have their respective batteries as power supplies and can continue operating when one of the batteries is depleted. A dust collection system for a power tool includes a power tool including a switch, a tool-body DC motor, a tool-body controller, and a tool-body battery, and a dust collection attachment attachable to the power tool and including a suction portion, a dust collector, a fan, a dust-collector DC motor, a dust-collector controller, and a dust-collector battery. When the dust collection attachment is attached to the power tool, the tool-body controller and the dust-collector controller are electrically connected to each other. The dust-collector controller uses the tool-body battery singly to supply power to the tool-body DC motor and the dust-collector DC motor or uses the dust-collector battery singly to supply power to the tool-body DC motor and the dust-collector DC motor.
