CGW 42334 4-1/2" X 5/8"-11 Type 29 60-Grit Z3 Zirconia Flap Disc

The CGW 42334 4-1/2" x 5/8"-11 Type 29 60-Grit Zirconia Flap Disc is designed for aggressive material removal on steel surfaces. This flap disc features premium zirconia alumina grain bonded to a poly/cotton backing, combining durability with a quality finish while maintaining efficient stock removal. The zirconia formulation is selected to support higher stock removal rates on demanding grinding tasks, making it suitable for heavy-duty applications that require rapid material removal without sacrificing control.

Key construction details include a Type 29 profile, which is optimized for angled grinding positions and access to contoured areas. The disc is sized for 4-1/2 inches in diameter with a 5/8-11 arbor, compatible with common angle grinders used in metal fabrication, maintenance, and workshop settings. An active grinding aid is included to promote cooler cutting under light pressure, potentially reducing heat buildup and extending disc life when used as directed. This combination of grain, backing, and design supports continuous grinding in aggressive use scenarios while maintaining steady performance.

For practical use, users should select the 60-grit rating for heavy material removal with a relatively aggressive cut, while following standard safety precautions and manufacturer guidance for disc selection, speed, and mounting. The package is listed as individual discs with a box quantity of 10, facilitating inventory management and replacement timing for ongoing maintenance tasks. The 13300 RPM specification indicates the maximum operating speed to ensure proper performance and safety during use.
