Abstract
A dust collection system for a power tool which comprises a drive unit, a body, a tool support, and a collection chute. The body defines an inlet opening and a discharge opening, the body having a communicating conduit located within the body which communicates the inlet opening with the discharge opening, and the body supporting the drive unit. The tool support is operably connected to the drive unit and defines a collection aperture, an exit opening which communicates directly with the inlet opening of the body during operational movement of the tool support, and a suction cavity in communication with both the collection aperture and the exit aperture. The collection chute has a collection end and a distal end, the collection end adapted to be connected to the body in a plurality of different positions in communication with the discharge opening of the body and the distal end adapted to be connected to the vacuum dust collector such that dust and other debris generated during operation of the power tool will be sucked sequentially through the collection aperture, the suction cavity, the communicating conduit, and out the collection chute.
