Abstract
An electrical tool (1) includes an electric motor (3), a fan wheel (4) that is connected in torque-proof manner to a drive shaft (8) of the electric motor (3) disposed within a housing (2) that includes at least one air inlet aperture (6) and at least one air outlet aperture (7). The at least one air outlet aperture (7) is arranged axially apart from the fan wheel (4) with regard to the axis of rotation (10) of the drive shaft (8). An air guide baffle ring (11) encloses the fan wheel (4) coaxially and has at least one air duct (12) which leads to at least one air outlet aperture (7) located axially at a distance from the fan wheel (4) for cooling the electric tool (1).
