What is the primary use of an angle grinder?

An angle grinder is primarily designed for grinding, cutting, and polishing materials, particularly metal. Its versatility comes from the ability to accommodate a wide range of attachments, including various types of grinding and cutting discs. This makes it an invaluable tool in metalworking, masonry, and fabrication tasks.

When using an angle grinder, operators can efficiently cut through pipes, sheets of metal, or concrete. Additionally, with the appropriate attachment, it can polish surfaces to a smooth finish, which is particularly important for metal parts to ensure they are ready for painting, finishing, or further machining. The combination of powerful rotational speed and the right disc enables the angle grinder to perform these tasks effectively.

The other options focus on applications that do not align with the angle grinder's primary function. Although it can be used in certain contexts involving wood or sanding, the angle grinder is not specifically designed for those purposes. Its strength lies in its ability to handle tougher materials like metal and masonry, making it distinct in its applications.
