CGW 42532 5" X 5/8"-11 Type 29 40-Grit Z3 Zirconia Flap Disc

The CGW 42532 5" x 5/8"-11 Type 29 Zirconia Flap Disc is designed for aggressive metal finishing tasks on steel. Crafted with premium zirconia alumina grain on a durable poly/cotton backing, this flap disc combines high stock removal with a controlled finish. The zirconia concentration and the Type 29 shape work together to optimize material removal while maintaining a workable edge geometry for contouring and workpiece access in curved surfaces.

Key features include an active grinding aid that aids in cooler cutting under light-to-moderate pressure, helping to reduce heat buildup during extended use. This disc is intended for heavy-duty, fast-paced grinding applications where substantial material throughput is required without sacrificing control over the workpiece finish. The backing material contributes to durability and helps sustain performance across multiple uses, while the 40-grit specification provides a balance between aggressive material removal and surface texture appropriate for subsequent finishing steps.

For compatibility, this disc is sized for 5 inches in diameter with a 5/8-11 inch Arbor/Shank attachment and is categorized as Type 29, which is suited for off-axis grinding and access to irregular shapes or angled surfaces. Each disc is provided in a package suitable for stocking and distribution, with ten discs per box, making it practical for production environments that require steady supply of high-performance flap discs. When selecting for a specific job, consider the need for rapid stock removal on steel and the potential impact of grind heat on the workpiece. The product’s construction and grit are aligned to support material removal rates while maintaining control under appropriate pressure.
