An abrasive tool is a device used to shape, grind, or polish materials through friction. These tools are typically made from hard materials like diamond, aluminum oxide, or silicon carbide. They come in various forms, including grinding wheels, sandpaper, and abrasive pads, and are commonly used in manufacturing, construction, and woodworking. Abrasive tools work by removing small particles from the surface of a material, allowing for precise shaping and finishing. They are essential in processes such as metalworking, where they help achieve smooth surfaces and accurate dimensions. Proper selection and use of abrasive tools can significantly enhance the quality of the final product.
