What is a Flap Disc?
A flapwheel and the related flap disk is an abrasive disk, used for metal finishing. Unlike the simpler flat disks, made from a circular flat sheet of a coated abrasive, a flap wheel is made of multiple overlapping small pieces or ‘flaps’, bonded to a central hub

Which flap discs are the best?
If you are looking for maximum performance in a flap disc, Ceramic is the best option. The ceramic grains micro-fracture as they grind, constantly exposing sharp edges and maintaining a high cut rate for the life of the disc.
Are flap discs any good?
Flap Disc Shapes
The steeper angle increases the grinding pressure and therefore speed of cut. But a steep angle makes it easier to dig into the metal. Flap discs provide the same action as a traditional sanding disc but with a significant increase in disc life.
How long should a flap disc last?
When used properly, a flap disc can essentially be used until the cloth is almost completely worn down to the back plate. In general, flap discs are designed for use on right-angle grinders at angles from 5 to 35 degrees.
What is the longest-lasting flap disc?
The three grains primarily used are aluminum oxide (consistent and low cost), zirconia alumina (the most versatile for the lowest cost), and ceramic alumina (the most expensive, but the longest lasting and most heat resistant).
What is the advantage of a flap disc?
Flap discs offer benefits such as fast stock removal and the ability to grind, blend, and finish with a single product, which can improve project timelines without compromising on results.
In general, you’re better off using a flap disc over a grinding wheel when abrading metal and applying a smooth finish.
