The CGW 42715 7" X 5/8"-11 Type 27 80-Grit Z3 Zirconia Flap Disc is designed for aggressive material removal on steel surfaces. Its Type 27 configuration provides a traditional flat grinding surface suited for grinding on flat or contoured workpieces, while the zirconia alumina grain is chosen for durability and extended life under heavy use. The disc is built on a poly/cotton backing, which helps balance rigidity and finish quality, contributing to consistent performance during demanding grinding tasks. The inclusion of zirconia within the abrasive grain supports higher stock removal rates compared with standard aluminum oxide finishes, making it suitable for applications where faster material removal is desired.
Construction features include an 80-grit zirconia formulation, a 7" diameter, and an 5/8"-11 arbor compatible with standard right-angle grinders. An active grinding aid is incorporated to promote cooler cutting action with light pressure, which helps control heat buildup and can improve dimensional stability on hotter workpieces. The combination of grain, backing, and grinding aid is intended to deliver efficient material removal while aiming to reduce heat-induced damage during prolonged grinding sessions.
Potential use cases center on aggressive stock removal on steel surfaces, where the balance of high removal rate and finish quality is important. Operators should apply moderate pressure and maintain appropriate wheel speed to maximize efficiency and minimize heat generation. This product is packaged as one disc per unit with ten discs per box, aligning with common stocking practices in metal fabrication, maintenance, and facility services environments. Ensure compatibility with your grinder’s arbor and clamp system, and verify your RPM limits align with the disc’s rated RPM of 8600 for safe operation.
