With mounted 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 3919, mounted flap wheels are designated as “flap wheels with shaft.” For coarse grinding work with a high stock removal rate and cool grinding. 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 the flat, molded-core design.
