ABSTRACT:
The safety vacuum shield of the present disclosure may be detachably secured to a hand held power tool for removing particulate materials while performing work upon a workpiece with the power tool. Applying the power tool to the workpiece generates turbulence which moves the particulate materials, including particles of the workpiece as well as the tool bit. The safety vacuum attachment includes a shield for containing the turbulence and the moving particulate materials within an interior region defined by the shield when the power tool is in use. A first opening through the shield permits the power tool to extend therethrough and into the interior region. A second opening through the shield permits a vacuum to be applied to the interior region for providing a vacuum slip stream to draw materials within the slip stream from the interior region by way of the second opening. The shield is formed in a generally cup-shaped manner with arcuate turbulence control edges for confining the turbulence caused by applying the tool to the workpiece, and for applying the moving particulate material to the intervening vacuum slip stream where the turbulence is broken for removing the particulate materials from the interior region defined by the shield.
