ABSTRACT:
A dust confining vacuum sander (10) that is primarily designed to be placed on an extension tube to sand ceilings and upper wall surfaces. Without the extension tube, the sander may also be used to sand other lower level and horizontal surfaces. The sander (10) is comprised of a dust-confining shroud (18) having a peripheral opening (18a) into which is captively retained a sanding pad (12) that extends above the opening. The bottom surface of the shroud includes a vacuum port (18b) that is connected to a vacuum unit (90) by way of a vacuum tube (26). When the sander is operated, the loosened dust enters the shroud and is sucked through the vacuum tube (26) into the vacuum unit (90). Thus, protecting the operator from the abraded dust and reducing the amount of dust in the work area.
