Abstract: A hand-held power tool has a tool member and a motor drivingly connected to the tool member, wherein the motor is arranged in a motor housing. A battery for driving the tool member is provided. A guide shaft has arranged on its first end the battery and on its second end the motor housing and the tool member. A rotatably power output part arranged on the motor housing is drivingly connected to the motor. The power output part supports the tool member. Cooling air is sucked through the guide shaft into the motor housing. Between the power output part and the motor housing an annular air exit gap is formed through which the cooling air exits the motor housing. At least one guide vane that projects into the annular air exit gap is provided.

Abstract: An electric power tool has a device housing with a rear grip extending in the longitudinal direction of the device housing. The device housing has first opposed housing sides and second opposed housing sides. An electric drive motor and its electronic control are arranged in the device housing. A battery pack compartment arranged in the device housing receives a battery pack that has a parallelepipedal shape and extends in a direction of a height axis, width axis and depth axis. The battery pack is arranged such that the width axis and the height axis extend transversely to the longitudinal axis of the device housing. The battery pack has narrow sides extending approximately parallel and at a minimal spacing relative to the first opposed housing sides, respectively. The battery pack has opposed end faces neighboring the second housing sides, respectively.
