The CGW 42502 5" x 7/8" Type 27 40-Grit Z3 Zirconia Flap Disc is designed for aggressive material removal on steel surfaces. Built with premium zirconia alumina grain on a durable poly/cotton backing, this flap disc combines rigidity and a smoother finish to support heavy-duty grinding tasks. The zirconia concentration enhances stock removal efficiency, making it well suited for demanding metalworking applications where faster material removal is desired.
This disc utilizes a Type 27 profile for right-angle grinding, providing a more conformal contact with the workpiece and an elongated contact surface to help manage heat generation. An active grinding aid is incorporated to promote cooler cutting and reduced heat buildup when pressed with light to moderate pressure, contributing to extended wheel life and steadier grinding performance. The 5" diameter with a 7/8" arbor size aligns with common shop grinding tools and allows straightforward integration into established setups. A practical packaging configuration includes 10 discs per box, facilitating replacement in busy production environments.
Suitable applications include aggressive heavy-duty stock removal on steel components where high material throughput is needed. Operators should monitor grinding pressure and workpiece temperature to maximize the benefits of the active cooling feature and to prevent heat-related warping or surface damage. This product is categorized under Facility Maintenance and is compatible with standard 5" flap-disc tools that accommodate 7/8" arbors. Regular inspection of backing material integrity and disc wear is recommended to ensure consistent performance and to determine when replacement is appropriate.
