A random orbital sander including a housing, a motor having a vertical axis in the housing, a pad coupled to the motor, a face on the pad extending substantially perpendicularly to the vertical axis, a shroud surrounding the pad, an opening in the shroud, and a dust discharge tube having an inner end in communication with the opening and an outer end on the dust discharge end extending at an acute angle to the face of the pad. The sander has a height of between 83 and 86 millimeters and can weight between 0.8 and 0.75 kilograms. The outer end of the dust discharge tube can extend between about 120 and 157 millimeters from the vertical centerline. A compressed air valve including a first cylindrical wall, a first bore in the first wall, a valve having a base with a second cylindrical wall in engagement with the first cylindrical wall, a second bore in the cylindrical wall, and an inclined surface in the second wall in communication with the second bore.
