•Sandpaper: Sandpaper is a type of abrasive material used for sanding or smoothing surfaces of various materials, including wood, metal, plastic, and more. It consists of a flexible backing material (paper or cloth) with abrasive particles, such as aluminum oxide, silicon carbide, or garnet, adhered to it. The coarseness or grit of sandpaper refers to the size of the abrasive particles and determines how smooth or aggressive the sanding action will be. Common grit sizes range from coarse (low grit number) to fine (high grit number).
•Grinding Head: A grinding head typically refers to a rotary tool attachment or accessory used for various grinding or polishing tasks. Grinding heads are commonly used with rotary tools like Dremel tools, die grinders, or other power tools that can accommodate attachments. These heads come in various shapes and sizes, each designed for specific applications, such as grinding, shaping, deburring, or polishing.
