Abstract
An electric hammer can collect dust without using an external dust collection device. An electric hammer includes a motor, a body incorporating the motor, a striker assembly operable in response to the motor being driven to strike a bit attached along a striking axis, a dust collection fan rotatable in response to the motor being driven, a dust collection channel having a suction port being open toward a tip of the bit to generate a suction force in the suction port in response to rotation of the dust collection fan, and a dust collector located on the dust collection channel to collect dust sucked through the suction port.
