With unmounted flap wheels, coated abrasive flaps are arranged radially around the core in a fan-like structure. The flexible flaps perfectly adapt to surface contours. The abrasive grain is embedded in the sturdy, flexible cloth backing material with a resinoid bond. In ISO 5429, unmounted flap wheels are designated as “flap wheels.” For aggressive grinding with maximum stock removal rate on hard materials that do not conduct heat well. Consistently high performance due to self-sharpening ceramic oxide grain. Active grinding additives in the coating substantially improve the stock removal rate, prevent loading, and result in cooler grinding.

• •Conforms to contours due to high flexibility.
• •Consistently high stock removal rate throughout the entire service life as new, aggressive abrasive is constantly exposed.
• •Can be used face-down very close to edges and in corners thanks to special clamping system.
