Unmounted Flap Wheels

unmounted flap wheels

For larger hand tools or off-hand applications, we provide flap wheels in diameters from 4" to 8" with 1" or 2" widths. A broad selection of grades is available to deburr edges, remove flash and parting lines, blend machine marks, apply a linear scratch pattern, or provide light blending, cleaning, or polishing. These sizes have a 1" or 2" center hole compatible with larger tool arbors. The larger wheels contain more flaps per wheel for faster cutting, increased productivity, and longer life.
