These high performance 150mm mesh sanding discs offer exceptional durability - able to maintain performance 10x longer than conventional sanding discs. The revolutionary designed mesh base is made from aluminium oxide which is resin bonded to provide extra-long lasting performance. The sanding debris moves through the mesh to avoid build-up and enables highly efficient dust extraction. The hook and loop backing allows the quick and easy changing of mesh discs and there is no need to align dust extraction holes, which saves time. Ideal for sanding and finishing wood, metal, aluminium alloy, painted surfaces, plastic and fillers. Compatible with all 150mm random orbital sanders with a hook and loop backing pad.
