Metabo Cordless Circular Saws
A circular saw is a type of power saw that uses a toothed or abrasive disc or blade to cut various materials in a rotary motion that revolves around an arbor. A hole saw and ring saw both use a rotary motion, but they are not the same as a circular saw. Circular saws can also be used to make the blade itself. Circular saws were invented in the late 1800s and were widely used in sawmills in the United States by the mid-nineteenth century.
A circular saw is a tool for cutting a variety of materials such as wood, masonry, plastic, or metal. It can be hand-held or machine-mounted. In woodworking, the term “circular saw” refers to both hand-held and table saws.
