<p>An abrasive sheet such as sandpaper (1) has standard dimensions to fit 1/3, 1/2 or 1/4 sheet sanding machines having dust extraction facilities. The sheet has perforated delineated areas (2, 2 min ) adapted to be removed by the user to form a pattern of holes in the sheet to correspond with the holes in the sole-plate of the particular model of sanding machine which the user is employing. This enables one sheet to be used with several different models. <IMAGE></p> |
