Do you want to replace your angle grinder or are you looking for an extra grinding disc? They come in different shapes and sizes, in particular in 115, 125, and 230mm. The kind of angle grinder that is best for you depends on your use. The larger your angle grinder, the bigger your reach is and the deeper the grooves will be. You can use a diamond grinding disc for tiles and a metal grinding disc for stainless steel, pipes, or tubes.
