    Abstract: A vacuum attachment for attachment to a rotary tool such as a drill is provided, wherein the vacuum attachment comprises a housing, a vacuum section having an air flow means powered by the rotary tool, a dust and debris collection area having an opening at one end, and which is separated from said air flow means by a filtering device located at a second end, and a rotary tool connection device connecting said air flow means to said rotary tool, wherein said connection device is directly connected to said rotary tool such that rotation of said rotary tool effects rotation of said air flow means. The vacuum attachment also preferably contains a rotation assembly comprising gears and/or belts and pulleys, which is used to increase the rotational speed of the air flow means to a value greater than the rotational speed of the drill. The vacuum attachment can be used to collect minor amounts of dust and debris generated by, for example, the use of the rotary tool.
