CGW 42722 7" X 7/8" Type 29 40-Grit Z3 Zirconia Flap Disc

CGW 42722 is a 7 inch diameter Type 29 zirconia flap disc designed for aggressive material removal on steel. The disc features a zirconia alumina grain on a durable poly/cotton backing, which combines strong stock removal with a smoother finish than standard alumina products. The zirconia concentration enhances abrasive performance, helping to maintain material removal rates under heavy-duty use while the poly/cotton blend contributes to durability and finish characteristics. An active grinding aid is incorporated to help encourage cooler cutting action under light pressure, which can be advantageous when working with heated or warping-prone materials.

This flap disc is specified with a 7/8 inch arbor/shank size and is rated for up to 8600 RPM, making it suitable for high-speed grinding on compatible screw-on or conditioning machines designed for Type 29 flat-shouldered configurations. The product is packaged with ten discs per box, and each disc is intended for individual use in demanding fabrication or maintenance applications where rapid stock removal is desired. When selecting this accessory, ensure compatibility with your grinder and guard clearance for a 7 inch diameter, Type 29 flap disc. The combination of zirconia grain and a flexible backing helps balance aggressive material removal with a reasonable surface finish, which is important for workflows that require subsequent finishing steps.

Note: Specific performance characteristics such as allowable material types, exact finish grade, or official safety certifications are not provided in the source data. Users should verify that the disc geometry, grit size, and RPM rating meet the requirements of their grinding operation and machine specifications before use.
