The working apparatus comprises a tool, which is rotatably driven by a drive motor (24) through a transmission (26). The cooling airflow moves to a coil and a commutator (41) during operation, and leaves a motor housing (35) through a passage opening (46) arranged in the flow path of the cooling airflow downstream of the commutator. The motor housing is configured to be closed at the front side (65) facing towards a transmission housing (70). The cooling airflow partially flows to the transmission housing through the flow connection. |
