ABSTRACT:
A self-contained vacuum circular saw is presented. The vacuum saw has a casing around the saw blade that includes an accordion type lower section attached to the lower platform of the saw. A number of vacuum tubes, preferably four, are attached to the side of the circular saw opposite the blade. The armature of the circular saw that turns the blade also turns the vacuum impeller on the side opposite the blade. An impeller vacuum chamber pulls in the dust and debris created by the saw blade and discharges the dust and debris into a disposable and removable vacuum bag. An important aspect of this device is that the motor that turns the saw blade also turns the impeller, thus making the self-contained vacuum saw moveable from site to site.
