The CGW 42774 Zirconia Flap Disc is a 7-inch diameter, 5/8-11 arbor size Type 29 flap disc designed for aggressive stock removal on steel. It uses premium zirconia alumina grain on a durable poly/cotton backing, combining robust material removal with a finish that helps reduce heat buildup during grinding. The zirconia concentration contributes to higher material removal rates, making this disc suitable for demanding metalworking tasks where efficient material thinning is needed.
Key construction features include the Type 29 profile, which enables aggressive grinding angles and access to curved or contoured surfaces, and a 60-grit rating that provides a balance between material removal and surface finish. An active grinding aid is included to help maintain cooler cutting action under light pressure, potentially reducing heat-related wear on the workpiece and the disc. This disc is intended for heavy-duty or aggressive applications and is designed to perform with high RPMs, listed at 8600 RPM, when mounted on compatible machines.
For practitioners, this flap disc suits standard metal fabrication workflows where fast stock removal on steel is desired and where a durable backing helps resist wear during extended use. The 7-inch size and 5/8-11 mounting are widely compatible with many angle grinder models, but users should verify arbor compatibility and RPM ratings for their specific equipment. The package quantity is 10 discs per box, enabling batch purchases for shop workflow efficiency and ongoing projects without frequent reordering.
