It includes a backing sheet (1) made of paper, plastic or the like in the top of which there is an orifice (11) surrounded by a region (12) which on its rear face is covered with a self-adhesive substance with low adherence designed to fasten the sheet (1) to the wall (3) during the drilling operation and prevent dust from slipping down between the wall (3) and the sheet (1) which is secured by its front face below the orifice (11), to a container (23) designed to collect the dust.
