CGW 42552 is a 5-inch diameter Type 27 zirconia flap disc designed for aggressive grinding on steel. The disc combines premium zirconia alumina grain with a poly/cotton backing to balance durability and finish quality, while the zirconia concentration facilitates high stock removal. An active grinding aid is included to promote cooler cutting with light pressure, which can help reduce heat buildup during extended grinding sessions.
This flap disc is engineered for heavy-duty, high-performance applications where fast material removal is prioritized. Its Type 27 configuration provides a depressed center suitable for flat or moderately contoured surfaces, enabling efficient material removal on a range of steel components. The 40-grit designation indicates a coarser abrasive surface intended for aggressive stock removal rather than fine finishing, making it suitable for initial material shaping and deburring tasks on ferrous metals.
Compatibility and handling details: the Disc is sized for 5 inches with a 5/8-11 inch arbor/shank, and operates at up to 12,200 RPM. Packaged as an individual unit with a box quantity of 10, this product is appropriate for shop inventories that require reliable, high-performance flap discs for steel grinding and surface preparation. When selecting a flap disc, verify spindle compatibility and rpm limits for your grinder to ensure safe operation and optimal results.
