Four kinds of flap wheel can be available:
1: Mounted Flap Wheel, with 1/4" or 1/8" shaft
2: Unmounted Flap Wheel
3: Non-Woven Flap Wheel
4: Non-Woven interleafed cloth flap brush

Flap Wheels are manufactured from strips of high quality aluminum oxide material or non-woven material closely packed and radically bonded to a shaft or metal center. These wheels are more durable and provide a longer and cooler cutting action than is possible using conventional discs. Recommended for cleaning, deburring, blending, and polish grinding on stainless steel, aluminum, etc. Conformable to most shapes, they are available in coarse to fine grit.
