A drywall-cutting tool comprises a rotary blade of a thin design that cuts a very small kerf resulting in a smooth cut as well as a small amount of dust. Any dust that is generated is immediately vacuumed away by an on-board vacuum system that collects the dust in a removable dust bag. Additionally, the saw is provided with an adjustable depth mechanism for the most common thicknesses of drywall. This feature allows for accurate cuts, especially in remodeling scenarios where drywall must be cut without damaging other building components behind the drywall.

1. A dust collecting drywall cutting tool comprising: a housing comprising a working end, a handle portion, and a battery attachment end;an electric motor disposed within said housing working end;a drive conversion means operably connected to said motor for transmission of power from said motor;a saw blade mechanically connected to said drive conversion means;a guard cover attachable to a side of said housing working end for at least partially covering an upper portion of said saw blade, said guard cover being a semi-circular having sidewalls and a flat lower edge for covering the upper portion of said saw blade; and,a dust passage defined between sides of said saw blade and said guard cover sidewalls;a depth guide mounted to said guard cover, adjustable to a selectable incremental depth position relative to said saw blade;a fan disposed within a fan housing located on said guard cover and mechanically connected to said drive conversion means for creating a vacuum within said dust passage;an outlet port in fluid communication with said fan and extending outward from said fan housing adjacent said fan and opposite said dust passage;a battery removably connected to said battery attachment end and electrically connected to said motor; and,a trigger disposed on said housing handle portion electrically connected between said battery and said motor for energizing said motor when depressed;wherein said dust passage collects and directs passage of particles of material produced during use of said tool through said guard cover and through said outlet port; and,wherein said guard cover further comprises a lip downwardly extending from an inside surface thereof below said outlet port. 2. The tool of claim 1, wherein said depth guide is a generally rectangular member having sidewalls, a flat bottom surface, and a central opening permitting said saw blade to pass through; wherein said depth guide is secured to a lower edge of said guard cover; and,wherein a retaining mechanism secures said depth guide at said selectable depth position. 3. The tool of claim 2, wherein said selectable depth position permits said saw blade to perform cuts in the range of and including one-half inch (½ in.) cuts and five-eighths inch (⅝ in.) cuts. 4. The tool of claim 2, wherein said retaining mechanism further comprises a pair of slide clamps. 5. The tool of claim 1, further comprising a dust collecting bag attachable to an outlet of said outlet port. 6. A dust collecting drywall cutting tool comprising: a housing comprising a working end, a handle portion, and a battery attachment end;a side handle removably attached to said housing working end;an electric motor disposed within said housing working end;a drive conversion means operably connected to said motor for transmission of power from said motor;a saw blade mechanically connected to said drive conversion means;a guard cover attachable to a side of said housing working end for covering at least partially covering an upper portion of said saw blade, said guard cover being a semi-circular having sidewalls and a flat lower edge for covering the upper portion of said saw blade; and,a dust passage defined between sides of said saw blade and said guard cover sidewalls;a depth guide mounted to said guard cover adjustable to a selectable incremental depth position relative to said saw blade;a fan disposed within a fan housing located on said guard cover and mechanically connected to said drive conversion means for creating a vacuum within said dust passage;an outlet port in fluid communication with said fan and extending outward from said fan housing adjacent said fan and opposite said dust passage;a battery removably connected to said battery attachment end and electrically connected to said motor; and,a trigger disposed on said housing handle portion electrically connected between said battery and said motor for energizing said motor when depressed;wherein said dust passage collects and directs passage of particles of material produced during use of said tool through said guard cover and through said outlet port; and,wherein said guard cover further comprises a lip downwardly extending from an inside surface thereof below said outlet port. 7. The tool of claim 6, wherein said depth guide is a generally rectangular member having sidewalls, a flat bottom surface, and a central opening permitting said saw blade to pass through; wherein said depth guide is secured to a lower edge of said guard cover; and,wherein a retaining mechanism secures said depth guide at said selectable depth position. 8. The tool of claim 7, wherein said selectable depth position permits said saw blade to perform cuts in the range of and including one-half inch (½ in.) cuts and five-eighths inch (⅝ in.) cuts. 9. The tool of claim 7, wherein said retaining mechanism further comprises a pair of slide clamps. 10. The tool of claim 6, further comprising a dust collecting bag attachable to an outlet of said outlet port.
