Grinding tools are specialized instruments used to shape, smooth, or finish materials, primarily metals and wood. They work by removing small amounts of material through abrasion, which is the process of rubbing one surface against another. Common types of grinding tools include grinding wheels, bench grinders, and angle grinders, each designed for specific tasks and materials. These tools are essential in various industries, including manufacturing and construction, as they help achieve precise dimensions and surface finishes. Proper use of grinding tools enhances efficiency and safety, making them vital for professionals and DIY enthusiasts alike.
