<p>The debris control device is for use with e.g. powered and manual hand-held drills 4 and similar devices which either drill or abrade materials to cause particulate dust to be generated. The device is a debris collector 30 defined from a sheet material with at least three V-shaped sheet elements 31, 32, 33. Each V-shaped element defines a V-angle, the sum of which being less than 360 degrees. The V-shaped elements are attached along only one edge 34 to define a pocket 38. An adhesive on one sheet surface enables the device to be releasably retained on an operating surface. The device may be formed from a readily foldable sheet material such as paper. A number of overlaid sheets on top of one another may form a pad of debris collector sheets.</p> |
