A circular saw is a type of woodworking machinery which is composed of a metal blade which allows the user to cut wood and lumber through a circular motion. Circular saws may be hand-held, meaning that they can be manually manipulated by the user on the piece of wood that is used, or table mounted where the user guides the wood through the circular saw. Circular saws are usually powered by electricity. However, there are some large scale circular saws that are used in lumber mills which utilize hydro-power.
