United Abrasives 58328 Fiber Disc is a premium-quality abrasive disc designed for aggressive grinding and surface preparation on tough metal substrates. With a 9-1/8" diameter and 7/8" arbor hole, it fits most standard right-angle grinders, offering versatility and consistent performance. Built with advanced 9.3 Power Max Ceramic grain, this disc delivers superior cutting power, faster stock removal, and extended life compared to conventional abrasives. Its 80 grit coarse structure provides efficient material removal, making it ideal for heavy-duty applications.
Engineered with a grinding aid formulation, the Fiber Disc minimizes heat build-up and reduces loading, maintaining a cooler cutting surface and preventing discoloration on metals like stainless steel, carbon steel, titanium, and high-nickel alloys. The self-sharpening ceramic grains continuously expose new cutting edges, delivering consistent performance and longer disc life.
