DEWALT Mesh Sanding Sheets last at least 4 times longer than traditional DEWALT sandpaper sheets. Fibres are drawn away from the surface of the sheet into the small holes, and don't sit between the material and abrasive. This optimises the sanding effect. The sanding sheets enable dust to be drawn through the mesh across a wider area rather than being limited to distinct holes in traditional sanding sheets. They are also much easier to select as there is no requirement to match a specific dust extraction hole pattern. The mesh sanding sheets have hook and loop fastening for quick and easy attachment. They can be easily cleaned to help prolong their life.
