CGW 42724 7" X 7/8" Type 29 60-Grit Z3 Zirconia Flap Disc

The CGW 42724 is a 7-inch zirconia flap disc designed for aggressive material removal on steel surfaces. It uses premium zirconia alumina grain bonded to a poly/cotton backing, a combination chosen to balance durability, finish, and effective stock removal. The zirconia concentration and Type 29 angle contribute to a versatile profile that handles heavy-duty grinding while maintaining a cooler cut under light pressure, aided by the disc’s built-in grinding aid. This makes it suitable for applications where rapid material removal is required without excessive loading or smearing, helping to manage grinding temperatures during extended use.

Constructed for demanding environments, this flap disc features a 7/8-inch arbor/shank size and a 60-grit grade, providing a coarse texture appropriate for initial shaping and deburring tasks. The Type 29 profile is commonly used for contouring and edge work on flat or mildly curved surfaces, enabling efficient stock removal on steel with a balance of control and aggressiveness. The disc is packaged as individual units within a bundle or box quantity of 10, facilitating inventory management for shops that perform high-volume grinding operations.

When selecting this disc, verify compatibility with your grinder and mounting fitment, and ensure the application aligns with 60-grit zirconia for material removal needs. The 7-inch diameter and 7/8-inch arbor are standard for many contemporary right-angle grinders, but always confirm that your tool accepts Type 29 flap discs and the appropriate RPM rating (8600 RPM) to avoid over-speed conditions. Maintain proper pressure and let the abrasive do the work to maximize wheel life and control heat buildup during heavy-duty use.
