<p>A dust collector (2) for collecting dust (12) created when drilling a hole (10) in a wall (9) consists of a hollow housing (5) with two opposed aligned apertures (6, 7). The housing is provided with an adhesive coated ring (8) surrounding one aperture so that the housing can be adhered to a wall. The drill bit is then passed through the two apertures to drill the hole in the wall. The dust generated is collected inside the housing.</p> |
