3M supply a range of Flap Discs that are ideal for use on a variety of materials. They are made from layers of abrasive cloth consisting of abrasive material. The abrasive cloth is angled on a supporting plate and last up to 10 times longer than conventional fibre discs. For use on wood, metal, painted surfaces and masonry. The advantage of flap discs is that as the material wears away it exposes a new, fresh face of abrasive therefore achieving much higher material removal. Flap discs are particularly effective for rust removal and general finishing applications.

What is a flap disc good for?

A flap disc is an important tool for metalworking and woodworking. It consists of overlapping abrasive, alumina cloth flaps that are glued onto a rigid backing plate. These discs are an ideal choice for grinding, deburring, and polishing metal surfaces such as steel, stainless steel, aluminum and other hard materials.

What grit flap disc do I need?

If you are looking for a grit flap disc, it is important to know what kind of material you will be working with and the level of detail you need from the grinding job. Different grits have different levels of aggressiveness, which can vary depending on the type of material you will be working with. A coarse grit flap disc is ideal for removing material quickly, while a finer grit will create a smoother and more finished look. Additionally, when selecting the right flap disc, it is important to consider the size of the area that needs to be worked on, as larger discs are better suited for larger projects.

Once you have determined what type of material you will be working with, it is time to select the right grit flap disc. The most common types of flap discs are coarse, medium, and fine. Coarse grits remove material quickly but leave a rough finish. Medium grits provide a balance between speed and quality of finish, while fine grits allow for superior control and higher quality.
