A cooling assembly for a power tool comprising an air mover configured to be disposed within a housing assembly at a first end of a generally longitudinal enclosure proximate to a handle enclosure, the air mover configured to direct air from outside of the housing assembly at the first end of the housing assembly into the housing assembly, and then to direct the air generally perpendicular to a longitudinally extending direction of the generally longitudinal enclosure; and a duct configured to connect to the air mover and be in fluid communication with the air mover at the first end of the generally longitudinal enclosure to direct the air from the air mover into the handle enclosure, the duct including: an inflow segment defining a first area for receiving the air from the air mover, an outflow segment defining a second area for directing the air from the air mover into the handle enclosure, and a connecting segment connecting the inflow segment to the outflow segment, characterised in that the first area of the inflow segment is axially offset from the second area of the outflow segment by the connecting segment, and the second area of the outflow segment being less than the first area of the inflow segment, the duct gradually narrowing the airflow from the air mover while directing the airflow toward the circuitry, the connecting segment tapering from the inflow segment to the outflow segment. an air mover configured to be disposed within a housing assembly at a first end of a generally longitudinal enclosure proximate to a handle enclosure, the air mover configured to direct air from outside of the housing assembly at the first end of the housing assembly into the housing assembly, and then to direct the air generally perpendicular to a longitudinally extending direction of the generally longitudinal enclosure; and a duct configured to connect to the air mover and be in fluid communication with the air mover at the first end of the generally longitudinal enclosure to direct the air from the air mover into the handle enclosure, the duct including: an inflow segment defining a first area for receiving the air from the air mover, an outflow segment defining a second area for directing the air from the air mover into the handle enclosure, and a connecting segment connecting the inflow segment to the outflow segment, characterised in that the first area of the inflow segment is axially offset from the second area of the outflow segment by the connecting segment, and the second area of the outflow segment being less than the first area of the inflow segment, the duct gradually narrowing the airflow from the air mover while directing the airflow toward the circuitry, the connecting segment tapering from the inflow segment to the outflow segment. an inflow segment defining a first area for receiving the air from the air mover, an outflow segment defining a second area for directing the air from the air mover into the handle enclosure, and a connecting segment connecting the inflow segment to the outflow segment, characterised in that the first area of the inflow segment is axially offset from the second area of the outflow segment by the connecting segment, and the second area of the outflow segment being less than the first area of the inflow segment, the duct gradually narrowing the airflow from the air mover while directing the airflow toward the circuitry, the connecting segment tapering from the inflow segment to the outflow segment.
