With more layers and a higher mesh density, the backing will be stronger and more durable — this is an important consideration when you’re examining the detailed specs of a flap disc. You should strongly consider a flap disc over a grinding wheel if you need a superior finish and greater ease of use during operation. Also consider your abrasive grit material, and choose your grit size to achieve the desired results. Aluminum Oxide: This is the original grit material used in the 1970s when flap discs were first introduced.

Disc for Your Project How to Select the Right Flap Disc for Your Project

The reason manufacturers use carbide tips for wood cutting discs is because carbide is incredibly hard. You can use a chainsaw adapter to turn your angle grinder into a wood saw at a lower cost than getting a real chainsaw. For wood, you should also use the flap discs on your angle grinder just like you would use a grinding wheel. If you need to drill some small holes in your DIY projects, this drill chuck attachment, along with your angle grinder, will make it possible in a few seconds without borrowing or purchasing a powerful drill. Use metal backings for concrete or engineered stones, and use fiberglass or plastic backings for most metal or wood jobs.When working with flap discs, always start with a heavy grit, then switch to a lighter 100-120 grits or use finer-grit discs at the final steps to remove deep scratches and gouges. When you need to remove or sand a lot of surface wood away, turning your angle grinder into a sander is the easiest and most cost effective way to do it. Remember, fiberglass backing is made out of layers of fiberglass that are mesh-bonded and pressed together.

Zirconia Alumina: This is a blend of Zirconia and Aluminum Oxide grain, and it’s great for carbon and mild steel application. One side of the metal disc is finished with abrasive grains which can be used to grind off rust or paint. Natural wood comes with a lot of flaws that need to be taken care of before using it for the desired project. An angle grinder disc is any disc designed to fit in an angle grinder and rotates at high speed to perform cutting and polishing operations.

Consider the number of flaps, angle and spacing to differentiate between two discs, both of which may specify “standard density flaps” or “high-density flaps. Instead of featuring a cutting or grinding disc, this wheel includes clusters of bristles protruding in a radial formation. Besides grinding concrete with these types of discs, you can also use them to grind granite, stone, marble, masonry, and similar materials.
