A hole saw dust collection device comprising:
- a dust cover, an inner hole cutter, an outer hole cutter, a plurality of motion transfer rollers, and a hand crank handle;
- wherein the hole saw dust collection device saws a rectangular hole in a target surface using the outer hole cutter;
- wherein the outer hole cutter is directed along a rectangular path inside of the dust cover by a plurality of outer rollers;
- wherein rotation of the inner hole cutter is transferred to the outer hole cutter via a plurality of inner rollers in contact with the inner hole cutter, the plurality of outer rollers in contact with the plurality of inner rollers, and the outer hole cutter in contact with the plurality of outer rollers;
- wherein saw dust produced by cutting the target surface is confined within the dust cover and is suctioned from the interior of the dust cover by a vacuum cleaner that is coupled to a dust port of the dust cover via a vacuum hose;
- wherein the plurality of roller adjustment apertures are a plurality of slotted apertures located in the top wall of the dust cover;
- wherein the plurality of roller adjustment apertures are oriented to align with radials emanating from the center of the bit aperture;
- wherein the dust cover comprises one or more side walls and a top wall;
- wherein the one or more side walls are sides of the dust cover that surround a circular hole and prevent the saw dust from exiting the dust cover laterally;
- wherein the top wall is a top of the dust cover;
- wherein the top wall is coupled to the top of the one or more side walls;
- wherein the top wall prevents the saw dust from exiting the dust cover vertically;
- wherein the dust cover comprises the dust port, a bit aperture, a plurality of roller adjustment apertures, and a spirit level;
- wherein the dust port is an aperture in the one or more side walls of the dust cover;
- wherein the dust port is surrounded by a rigid tube such that the vacuum hose from the vacuum cleaner removably couples to the dust port;
- wherein operation of the vacuum cleaner while the vacuum hose is coupled to the dust port suctions the interior of the dust cover and removes the saw dust created by cutting into the target surface;
- wherein the bit aperture is an aperture located at the center of the top wall such that a hex shank of the inner hole cutter passes through the bit aperture to exit the dust cover;
- wherein the bit aperture comprises a bit bushing to reduce friction between the hex shank and the top wall of the dust cover;
- wherein the spirit level is an instrument that indicates whether the dust cover is level;
- wherein the spirit level is used to orient the rectangular hole;
- wherein the inner hole cutter comprises an arbor, a hole saw blade, a pilot bit, and the hex shank;
- wherein rotation of the inner hole cutter cuts the circular hole using a first kerf of the hole saw blade;
- wherein rotation of the inner hole cutter transfers motion from the hole saw blade to the outer hole cutter by rotating the plurality of inner rollers and the plurality of outer rollers.
