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 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.

Pferdergonomics:
PFERDERGONOMICS recommends mounted flap wheels to reduce vibration and noise produced during use and to improve comfort when working.
Recommendations for use:
Flap wheel wear and the thermal load on the workpiece are reduced by decreasing the contact pressure and peripheral speed, and by adding grinding oil.
Recommendations for use 1:
Stock removal rate should be increased by using a coarser grit, not by increasing the contact pressure. This avoids unnecessary flap wheel wear and prevents the thermal load of the workpiece.
Recommendations for use 2:
Increasing the speed results in a slightly finer surface quality. An increase in contact pressure results in a slightly coarser surface. The softer the workpiece material, the coarser the resulting surface (when using the same grit size).
Recommendations for use 3:
For the best performance, use with a recommended peripheral speed of 3,000-4,000 SFPM. This provides an ideal compromise between stock removal rate, surface quality, thermal load on the workpiece and tool wear.
Recommendations for use 4:
Use the appropriate grinding oil for the material to significantly increase the service life and the abrasive performance of the discs.
Safety notes:
For safety reasons, the maximum permitted rotational speed indicated must never be exceeded.
Safety notes 1:
The contact pressure has to be reduced significantly when the optimum rotational speed is exceeded.
Safety notes 2:
Ensure the clamping depth is at least 5/8" and the specified maximum rotational speed is not exceeded with unsupported shank lengths.

Other Details
Can be used face-down very close to edges and in corners thanks to the flat, moulded-core design.
Conforms to contours due to high flexibility.
Consistently high stock removal rate throughout the entire service life as new, aggressive abrasive is constantly exposed.
