A circular saw is a powerful handheld tool equipped with a rotating blade used for making straight cuts in materials like wood, plastic, and sometimes metal. The saw comes in various blade sizes, with 9″ and 7″ blades being popular options; larger blades provide deeper cuts and are suited for thicker materials.

This tool is favored in construction and woodworking for its ability to make long, straight cuts quickly and accurately. Circular saws are available in corded and cordless models, with adjustable cutting depths and bevel angles. These adjustments allow users to make cuts at different angles, making circular saws essential for framing, carpentry, and general-purpose cutting.
