The CGW 39465 flap disc is designed for versatile material removal and finishing on ferrous and non-ferrous metals, as well as plastics and wood. This 4-1/2-inch diameter, 7/8-inch arbor Type 29 disc features an 80-grit aluminum oxide grain bonded to a polyester backing, delivering a balanced mix of cutting action and shearing abrasion. The XL construction implies an extended flange or layer count that supports higher material removal rates and smoother finishing in applications requiring more aggressive stock removal. Operating at up to 13,300 RPM, the disc is suitable for power tools that match these speed ratings, enabling efficient work in shop or fabrication environments.
Constructionally, the premium aluminum oxide grain is standard for general-purpose grinding and blending tasks, while the Type 29 angled profile helps achieve aggressive material removal in edge and bevel areas. The combination of grain, backing, and disc geometry influences heat generation, edge wear, and the finish quality you achieve, making it important to select the appropriate wheel for the material and task. Practical considerations include ensuring the tool’s arbor size is compatible with your spindle, using proper safety gear, and matching disc speed with tool capabilities to avoid over-speed conditions. The packaging lists a box quantity of 10 discs per box and a per-disc packaging size, which can affect procurement planning and inventory.
