The CGW 41774 flap disc is a 4-1/2 inch diameter, 5/8-11 thread arbor Type 29 flap disc engineered for steel applications. It uses zirconia grain on a durable poly/cotton backing, designed to deliver both effective material removal and a consistent finish. The zirconia abrasive provides efficient cutting action and heat resistance, while the backing material contributes to durability and finish strength during grinding operations.
This disc is built to run at high RPMs, with a maximum speed rating of 13,300 RPM, making it suitable for aggressive material removal on steel surfaces when paired with the correct grinder setup. The 60-grit formulation offers a balance between material removal rate and a finer finish, appropriate for intermediate grinding and surface prep tasks where a smoother final texture is desired without sacrificing productivity. The Type 29 configuration presents a depressed top for aggressive grinding and access to recessed areas, helping with contour work and edge finishing in practical shop environments.
Practical considerations include ensuring proper mounting on compatible 4-1/2 inch angle grinders with a 5/8-11 thread, and confirming that the workpiece is securely clamped and free of hazards before use. The package is supplied as individual discs, with a box quantity of 10, providing convenient stock for maintenance cycles and consistent availability in facility-maintenance workflows.
