Electric tools are powered by electricity, making them more efficient and easier to use than manual tools. They come in various types, including drills, saws, and sanders, and are commonly used in construction, woodworking, and home improvement projects. These tools can be corded, requiring a direct power source, or cordless, which use rechargeable batteries for portability. The advantages of electric tools include faster operation, reduced physical effort, and consistent performance. Safety features, such as automatic shut-off and protective guards, are often included to minimize the risk of accidents. Proper maintenance and usage are essential for ensuring longevity and effectiveness in tasks.
