Abstract
A dust collector assembly is provided for use with a hand-held drilling device, or drilling holes in a ceiling to prevent the dust and other debris from falling onto the user of the drilling device. The assembly includes a rounded oblong body shell defining a chamber open on one side. The shell wall has an edge extending therealong, on the one side, that is placed against the ceiling into which holes are to be drilled. The body shell includes a drill hole therein that enables the drilling device to be inserted therethrough into the chamber. A hose connector, received in an opening at the opposite end of the body shell, is adapted to be connected to a suction hose. One of a plurality of drill hole adaptors is received in the drill hole in the body shell. The adaptors have central apertures of different diameters. Thus, drilling elements of different effective outer diameters can be used with the assembly while substantially maintaining a desired spacing between the drilling element and the adaptor by selecting and using an adaptor having a diameter correspondingly matched to the effective diameter of the drill element.
