Which tool is specifically used to grind away heavy metals like welds?

The angle grinder is specifically designed for grinding, cutting, and polishing materials, making it particularly effective for grinding away heavy metals such as welds. It features a rotating abrasive disc that can handle tough materials, allowing users to remove excess metal, smooth surfaces, or shape components effectively. This versatility in handling various grinding tasks, particularly on heavy-duty materials, sets the angle grinder apart from other tools.

Circular saws, while effective for cutting through different materials, do not provide the same grinding capability for heavy metals. Pneumatic nailers are designed for driving nails into materials and are not suited for grinding tasks. Reciprocating saws are ideal for demolition and cutting, but their design is not conducive to grinding surfaces. Therefore, the angle grinder is the appropriate choice for this specific application.
