Power saws are tools designed to cut through various materials, primarily wood, metal, and plastic. They use a rotating blade or a chain to make precise cuts, making them essential for construction, woodworking, and metalworking projects. Common types include circular saws, jigsaws, and chainsaws, each suited for specific tasks. These saws are powered by electricity or batteries, providing greater efficiency and speed compared to manual saws. Safety features, such as blade guards and automatic shut-off mechanisms, are often included to protect users. Proper handling and maintenance are crucial for safe operation and longevity of the tool.
