With the Norton Norzon F827 fibre disc, you tackle heavy grinding and stock removal tasks quickly and efficiently. Thanks to the self-sharpening zirconia grain in coarse P36 grit, you can grind down heavy weld seams and strip thick rust or old paint layers with ease. The tough 0.8 mm vulcanised fibre backing delivers outstanding tear resistance and stability under high working pressure on ferrous and non-ferrous metals. Designed with a standard 22.23 mm bore, this 180 mm disc mounts easily onto a suitable backing pad on your angle grinder.
