Coated discs are essential tools for grinding, finishing, and polishing a wide range of materials, from metal and wood to ceramics and plastics. These discs feature an abrasive layer, such as aluminium oxide, silicon carbide, or ceramic, adhered to a durable backing material. They come in various grit sizes to provide different levels of coarseness, allowing for tasks ranging from heavy material removal to fine surface finishing. Coated abrasive discs are commonly used with sanders but can also be used with certain grinders and other power tools, making them invaluable for metalworking, woodworking, and surface preparation in automotive and construction industries. Their versatility, combined with the ability to tackle numerous applications, makes coated discs indispensable for achieving precise and smooth finishes on a variety of workpieces.
