CGW 48116 5" Dia x 7/8" 80-Grit Zirconia Blue Fiber Disc

CGW 48116 is a 5 inch diameter fiber disc designed for efficient metal finishing tasks, particularly blending welds on steel and stainless steel. The disc combines a high concentration of zirconia abrasive grains with heat-treated aluminum oxide, delivering enhanced cutting action and heat resistance. Its unique grain fracturing characteristics help maintain consistent performance throughout the life of the disc, reducing the need for frequent changes during a continuous grind.

This 80-grit zirconia fiber disc provides a balance between material removal and surface finish, suitable for light to moderate stock removal and blending operations. The zirconia and aluminum oxide blend is chosen to withstand the heat generated during grinding, minimizing loading and discoloration on typical metal substrates. The disc is configured for a 5" diameter with a 7/8" arbor, compatible with standard right-angle grinders common in facility maintenance and fabrication settings. Each disc is designed for single- or multiple-pass use depending on workload, with packaging that supports bulk procurement in box quantities.

When selecting this disc, consider the required material removal rate and finish quality, as well as operability with your grinder’s RPM. Running at a rated 12,200 RPM, operators should observe standard safety practices and verify compatibility with their machine before use. The packaging specifies the product as 25 discs per box, enabling efficient stocking for maintenance tasks that involve routine surface blending and weld finishing.
