CGW 41734 4-1/2" X 5/8"-11 Type 29 60-Grit ZPC Zirconia Flap Disc

The CGW CGW41734 is a 4-1/2 inch diameter zirconia flap disc designed for aggressive grinding on steel. It features zirconia grain bonded to a poly/cotton backing, which provides durability and finish strength during use, helping to balance material removal with a smoother final surface. The Type 29 flap arrangement is suited for contoured grinding in close-to-edge applications, enabling grinding at more aggressive angles on flat or mildly curved surfaces. With a 60-grit designation, this disc is positioned for rapid stock removal while still yielding a reasonable surface finish, and it is rated for up to 13,300 RPM to match typical high-speed tools used in metal fabrication and maintenance tasks.

This disc is intended for steel applications, and its construction is geared toward mixed-metal removal and finishing work. The zirconia grain is known for its long life and heat resistance, which helps manage heat buildup during heavy grinding tasks, potentially reducing glazing and loading compared with some other abrasive systems. The product is packaged as individual discs, with 10 discs per box, making it suitable for ongoing operations that require consistent, repeatable performance across multiple workpieces.

When selecting and using this flap disc, ensure compatibility with a 5/8-11 arbor and verify that the tool and spindle speeds align with the 13,300 RPM rating to maintain safe operation and maximize disc life. Regular inspection of flaps for wear and proper seating on the arbor will help maintain consistent grinding action and surface quality over time.
