Abstract:
A dust collection device for a sanding tool includes a paper bag having a sidewall with an inner surface and a coupler attached to the bag. A sleeve having an outer surface, a sleeve sidewall, a first end, a second end, and at least one gap at either the first end or the second end is positioned within the bag. The sleeve's first end is positioned adjacent the coupler to direct incoming air towards the sleeve and the sleeve is positioned within the bag such that a bypass volume is present between the outer surface and the inner surface.
