Dust and debris resulting from the sawing or cutting of concrete masonry units, blocks, bricks, tiles and other masonry products is collected via a three point dust and debris collection system. A movable work supporting table for cooperation with a masonry saw has a grated surface, a vacuum chamber below the grated surface acting as one collection point or area, a heavy debris collection chamber below and in communication with the table vacuum chamber acting as another collection point or area, and a shroud or hood assembly extending rearwardly from the table adapted to extend about the sides and rear of the saw blade and including a vacuum chamber acting as a primary collection point or area. The system is highly effective in achieving dust capture.
