Product Features

3 Inch Sanding Discs is a commonly used tool. These discs come in a wide range of materials, grits, and features to suit different purposes.

Material

Sanding discs can be made of various materials such as aluminum oxide, silicon carbide, zirconia alumina, ceramic, and diamond. Each material has unique properties that affect the disc's durability, aggressiveness, and cost. Aluminum oxide is a common choice for general-purpose sanding, while zirconia alumina or ceramic discs are ideal for heavy stock removal or metalworking applications.

Grits

Sanding discs are available in a range of grits from fine to coarse, expressed in numbers such as 80, 120, or 220. The higher the grit number, the finer the abrasives and the smoother the finish. A typical sanding sequence may involve starting with a coarse grit to remove rough spots, followed by medium grit to refine the surface, and finishing with a fine grit for a polished look.

Product Application

3 Inch sanding discs are commonly used for removing paint and rust from metal surfaces. Grinding is the process of using sanding discs to cut away the topmost layer of the metal. Once the surface has been ground, the polishing process begins. Polishing requires using finer grit sanding discs to smooth out the surface and bring out the luster of the metal. Sanding discs are ideal for grinding and polishing because they can quickly conform to the shape of the object you're working on, ensuring a consistent finish.
