A grinding tool accessory for containing and removing dust formed by a grinding disk comprises: a flexible housing adapted for mounting on the grinding tool and defining a first chamber for collecting the dust prior to removal, the housing having an edge spaced from an outer perimeter of the grinding disk and defining an annular gap; the housing having an outlet adapted for connection to a source of vacuum and a dust collector; a brush extending from the edge and together with the grinding disk defining a second chamber, the brush having bristles with different lengths dimensionally related to the gap, dust being drawn from the second chamber into the first chamber through the gap and thereafter into the dust collector by the vacuum; and, the housing having at least one sealable hole to adjust the vacuum for optimizing containment and collection of the dust as the grinding tool is moved over flat and contoured portions of a work surface.

[ What is claimed is:] [9.] A grinding tool accessory for containing and removing dust formed by rotary action of a grinding disk on a work, surface, the accessory comprising:a flexible housing adapted for mounting on said grinding tool and defining a first chamber for collecting said dust prior to removal, said housing having an edge opposite and spaced from an outer perimeter of said grinding disk and defining a substantially uniform annular gap;said housing having an outlet adapted for connection to a source of vacuum and a dust collecting container; and,a brush extending from said edge and together with said grinding disk defining a second chamber in which said dust is created during said rotary action of said grinding disk, said brush having bristles with different lengths, said dust being drawn from said second chamber into said first chamber through said gap and thereafter being drawn from said first chamber into said dust collecting container by said source of vacuum,whereby said dust is substantially completely contained and collected during said rotary action of said grinding disk as said grinding tool is moved over flat and contoured portions of said work surface; andwherein said housing comprises at least one hole communicating between said first chamber and ambient pressure, said at least one hole being sealable to adjust said vacuum.
