Abrasive wheels are tools used for grinding, cutting, or polishing materials like metal, wood, and stone. They consist of a circular disc made from abrasive particles bonded together, which allows them to remove material efficiently. Commonly found in workshops and manufacturing settings, these wheels come in various sizes and types, depending on the specific application. Safety is crucial when using abrasive wheels, as they can generate sparks and debris. Proper protective equipment, such as goggles and gloves, should be worn. Additionally, users must ensure that the wheels are compatible with the grinding machine and are installed correctly to prevent accidents.
