What is a Flap Disc for Angle Grinder?
A flap disc is an abrasive disc made of small sheets of overlapping sandpapers arranged in a circular shape. The layered overlapping segments or "flaps" have small grains of abrasives such as aluminum oxide. These abrasive grains are attached to a backing cloth which is normally made from polyester, cotton, or blended material.
The cloth is cut into smaller sections or flaps and layered across the disc. This is where the flap disc gets its name. These flaps are glued onto a backing plate made of plastic or fiberglass.
How the disc itself performs when being used will depend on the type of abrasive material used and its grit size. This is an important step because the selection of abrasive material and grit size will determine the effectiveness of the finishing or grinding you intend to do on the metal.
You can select between single and high-density flap discs. The high-density versions have more cloth which makes them thicker, and they will last longer compared to the single versions. You can also select the size of the flap discs which range from two to seven inches in diameter. Many people use the two-inch disc to replace blending discs as they tend to be far more durable.
The main benefit of using a flap disc is its low wear and ability to apply varying degrees of finish with the same disc. Each flap on the disc touches the workpiece surface at a different angle. This not only reduces swirl marks but also prevents repetitive damage to the surface, which is common with flat sanders such as palm sander.
What are flap discs used for?
Flap discs are primarily used for metalworking for grinding, blending, clean up welds, chamfering, etc. They can be used for finishing metals by quickly removing burrs and producing a smooth finish on the edges.
Flap discs are also used to remove paint, rust, and corrosion from metal surfaces.
