Abstract
A power tool with a working head for holding a working element. The power tool includes a motor having a motor output shaft for driving said working element and a duct having an inlet locatable in proximity to a point of contact between the working element and a workpiece. A dust collection chamber has an inlet in fluid communication with an outlet from said duct, and an outlet in fluid communication with atmospheric air. A fan is operable to transport air from the inlet of said duct to the inlet of said dust collection chamber. A first drive wheel is mounted on the motor output shaft. A second, driven, wheel mounted on a second shaft and a drive belt connects the first, drive wheel to the second, driven wheel, for transmitting power from the motor output shaft to the second shaft. The fan is mounted on the second shaft.
