1. A dustless sanding attachment comprising:
a shroud having a planar top wall with an aperture and four peripheral planar side walls extending downward from the planar top wall at right angles to form a box-shaped structure with an open bottom;
a parallel pair of opposing standoff posts integral to the inner surface of the top wall of said shroud, each comprising a neodymium-iron-boron NdFeB disc magnet embedded therein;
a port tube with an open first end and an open second end, the open first end designed to provide a clearance fit that allows it to slide along the longitudinal extents of a tubular member, said port tube having an array of fin members bonded along their longitudinal edges to an inner wall of said port tube;
a coupling nut having inner threads to provide fastening between said port tube and a thread shaft of an ancillary sander element, where a first portion of said coupling nut is attached to and surrounded by said inner wall of said port tube and a second portion of said coupling nut extends beyond a terminal surface of said second end of said port tube; and
a flexible bellows for connecting to said shroud and said port tube, thus providing a vacuum seal therewith.
