The CGW 41742 is a 4-1/2 inch by 7/8 inch Type 27 zirconia flap disc designed for grinding and finishing steel surfaces. The disc features zirconia grain on a durable poly/cotton backing, which provides both abrasive performance and finish integrity during extended use. The Type 27 configuration gives a depressed center angle, making it suitable for flat and slightly contoured workpieces where more aggressive material removal and a smoother finish are desired. The 40-grit specification indicates a coarse abrasive intended for rapid stock removal while still delivering a workable surface texture.
Constructed to withstand the rigors of high-speed grinding, this flap disc is rated at 13,300 RPM and is sized for 4.5 in. diameter with a 7/8 in. arbor/shank compatibility. The poly/cotton backing aids in durability and finish strength, helping maintain disc integrity across repeated passes on tough steels. Each package contains 10 discs, making it practical for dispersed use across multiple grinders or for stocking purposes in a shop environment.
When selecting this flap disc, verify that your grinder uses a compatible 7/8 in. arbor and that the application aligns with Type 27 depressed-center discs for stable contact and effective material removal. Regular inspection for wear and proper mounting is advised to ensure continued performance and safety during operation.
