Abrasive wheels are tools used in various industries for grinding, cutting, and polishing materials like metal, wood, and stone. They are made from hard materials, such as aluminum oxide or silicon carbide, which allow them to remove material efficiently. These wheels come in different shapes and sizes, depending on the specific application and the type of machine they are used with, such as bench grinders or angle grinders. Safety is crucial when using abrasive wheels, as they can pose risks if not handled properly. Users should wear appropriate personal protective equipment (PPE), such as safety goggles and gloves, to prevent injuries from flying debris or accidental contact. Additionally, it is important to ensure that the wheels are correctly mounted and maintained to avoid breakage during operation.
