The CGW 39434 flap disc is a 4-1/2 inch diameter, 5/8-11 threaded arbor Type 29 work accessory designed for aggressive metal finishing and surface prep. It uses premium Aluminum Oxide grain bonded to a durable polyester backing, providing abrasive action suitable for grinding and blending on a variety of materials. The Type 29 profile concentrates grinding power for edge-work and conical shaping, enabling efficient material removal with fine 60-grit size. This combination is intended for tasks that require a balance of material removal and surface finish on ferrous and non-ferrous metals, as well as plastics and wood, depending on the workpiece and setup. The disc is rated to operate at up to 13,300 RPM, which informs the appropriate spindle speed and setup on compatible grinders to maintain safety and performance.
Practically, this flap disc is compatible with standard 4-1/2 inch angle grinders featuring a 5/8-11 arbor. Its 60-grit Aluminum Oxide on a polyester backing is a common choice for aggressive deburring, edge chamfering, and rust or scale removal on metal surfaces, as well as preparing plastics and wood for finishing where a controlled material removal is required. When selecting this disc, ensure the grinder is configured for Type 29 discs and that the RPM rating aligns with the tool’s maximum speed to avoid safety hazards. The packaging indicates a per-disc size with a box quantity of 10, which helps with stocking and procurement planning.
