Power tools are electric or battery-operated devices that help people perform tasks more efficiently and with less effort than manual tools. Common examples include drills, saws, and sanders. These tools are designed to make construction, woodworking, and home improvement projects easier and faster, allowing users to achieve professional results with less physical strain. Using power tools can significantly enhance productivity, especially for larger projects. They often come with various attachments and settings, making them versatile for different tasks. Safety is important when using power tools, so it's essential to follow guidelines and wear protective gear, such as safety goggles and ear protection.
