Abstract: Abrading and cutting devices such as saws include waste containment systems and methods to improve removal of slurry or other contaminants from a work area during operations, and separation of slurry from a carrying medium such as air. A vacuum bar includes high and low vacuum openings to help focus flow and to conserve vacuum pressure. One opening faces the saw blade. A slurry containment and separation container includes walls and configurations for the inlets and outlets that enhance cleaner separation of the air and the slurry. Coolant is applied to the saw blade to make operation and cleanup more efficient. The vacuum generator can operate off of the power generated by the machine.
