The circular saw is a metal disc or blade with saw teeth on the edge as well as the machine that causes the disk to spin.
Circular Saw is a tool for cutting wood or other materials and may be hand-held or table-mounted.
Circular Saw can also be used to make narrow slots (dados)._______
Most of these saws are designed with a blade to cut wood but may also be equipped with a blade designed to cut masonry, plastic, or metal._______
There are also purpose-made circular saws specially designed for particular materials.
While today circular saws are almost exclusively powered by electricity, larger ones, such as those in "saw mills", were traditionally powered by water turning a large wheel._______
