<p>A dust and particle collecting attachment for power drills that is releasably secured to the drill and the inlet aperture (1) positioned under the drilling site so as to collect the waste material. A returnable sliding or deformable section (4) allows the drill to penetrate the material being drilled and ensures the position of the inlet aperture is maintained when the drill is withdrawn. Embodiments are also described where suction is applied, wherein the air flow is generated within the attachment, by the power drill or via a domestic/industrial vacuum cleaner. <IMAGE></p> |
