A net sanding material with a medium grit of 240 made from white aluminum oxide. The white aluminum oxide features a finer and more open grain structure, making it excellent not only for wood and metal surfaces but also for paints and lacquers. A long-lasting sanding performance is ensured by the grid structure. The sanding dust is removed much more effectively from the workpieces being treated, preventing any negative impact on the sanding grain. The existing hook-and-loop attachment allows for quick and easy fastening to the machine. To guarantee optimal grip and the longevity of the sanding material, the optionally available sanding disc guard must be placed between the sanding material and the sanding disc.
