ABSTRACT:
One embodiment of a drill press table accessory has a work surface with an opening therethrough for passing at least a portion of a drill bit. A vacuum channel communicates with the opening and with a vacuum port for connection to a vacuum source. In operation, a pressure differential may be communicated from the vacuum source to the opening to remove dust and debris as a work piece is operated on. An additional drill press table embodiment has upper and lower tables hingedly attached whereby the upper table may be oriented at an angle to the lower table so that a work piece can be operated on at an angle.
