The X-LOCK R780 Best for Metal and Inox Fibre Disc is excellent for removing material quickly when grinding on metal and Inox surfaces. Its self-sharpening Ceramic Grit Technology creates new sharp cutting edges during the sanding process for high stock removal in coarser grits and consistent surface quality in finer grits without disc wear. The disc's top size coating with cooling aids makes it ideal for use on Inox as well as mild steel surfaces. Its backing material is vulcanised fibre, providing stability during sanding process. This fibre disc is perfect for weld removal, edge chamfering, blending, stock removal, removing discolouration, surface treatment, structuring and final sanding. Changing fibre discs is fast and convenient thanks to the keyless X-LOCK system. Discs are suitable for clamping on an X-Lock or standard rubber backing pad. X-LOCK sanding discs also fit standard angle grinders.
