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 universal applications from coarse to fine grinding.

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 3,000-6,000 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.
Recommendations for use 5:
For the best results, use a power tool with 1,000–1,500 watts.

Safety notes:
Unmounted flap wheels should only be used with the appropriate clamping flanges.
Safety notes 1:
For safety reasons, the maximum permitted rotational speed indicated must never be exceeded.
Safety notes 2:
The contact pressure has to be reduced significantly when the optimum rotational speed is exceeded.
Safety notes 3:
The maximum permitted peripheral speed is 9,800 SFPM.
