The CGW 39942 flap wheel is a 2-1/2 inch diameter, 1 inch wide flap wheel with a 1/4 inch shank, designed for precision grinding and surface finishing in tight spaces. Its construction uses firm aluminum oxide coated abrasive material, arranged in narrow flaps that fan out around the shaft to provide consistent cutting action, extended life, and predictable material removal when used with appropriate power tools. This configuration helps maintain a steady grind across curved or contoured surfaces, making it suitable for small or hard-to-reach areas where wheel size limits access.
The 80-grit specification indicates a balance between material removal rate and surface finish, suitable for deburring, shaping, and light blending on a variety of materials. The wheel is intended for use on metals such as steel, stainless steel, iron, brass, and aluminum, as well as plastics, fiberglass, wood, and certain glass surfaces, depending on the process and tool compatibility. Operators should follow standard safety practices for grinding and ensure the wheel is mounted per manufacturer guidelines to avoid vibration or runout that could affect performance.
This product ships in units suitable for resale and is commonly used in facility maintenance, workshop fabrication, and repair tasks where access is constrained by size. Compatible tools should have the corresponding 1/4 inch arbor/shank and be capable of handling up to 20,000 RPM, matching the wheel’s rated speed to prevent wheel failure and ensure safe operation. For best results, select the correct grit and wheel size for the material and desired finish, and inspect the wheel for wear or damage before use.
