Title of the Invention VACUUM-OPERATED CUTTING TOOL AND SYSTEM THEREFOR Abstract of the Disclosure A vacuum-operated cutting tool and system includes a power tool that operates in response to a vacuum induced fluid-flow. The tool includes a housing having an impeller section with an outlet adapted for connection to a vacuum- inducing source and an inlet through which ambient air enters the tool. A rotatably mounted turbine-impeller is located within the impeller section of the housing and is adapted to rotate in response to the vacuum-induced fluid- flow. In the preferred embodiment, a motion converting mechanism is connected between the turbine-impeller and a drive spindle equipped with a circular saw blade. The motion converting mechanism converts the rotary output motion of the turbine-impeller to a rotary oscillating motion so that the saw blade is suited for use in cutting platter casts. The air inlet of the housing is advantageously located in the cutting zone of the saw blade to entrain and remove debris generated during the cutting operation.
