A circular saw is a powerful, portable, and versatile tool designed to cut wood with a large spinning blade. While most circular saws are specifically designed to cut wooden materials, most can also be used with specialty blades made to cut metals, plastics, and other industrial materials. Circular saws have a flat, pivoting shoe that moves up and down for depth adjustment, and to the right or left (although generally to the left, from zero to 45 or 50 degrees) for angled cuts or edging. Circular saws are also built with a blade guard which covers the blade almost entirely to protect operators from the jaws of a spinning blade. Most circular saws also have additional safety features like blade and trigger locks -- but don't let these mechanisms fool you. Circular saws can be very dangerous, and because they are relatively simple to use and maneuver, it is easy to forget the potential dangers of a sharp, and spinning power tool as you work.
Circular saws are excellent for rip cuts, cutting with the grain, and also for cross cuts, or cuts made against the grain. The saw is also surprisingly accurate - even without a guide. Because the blade is so large, its bigger size generally keeps your cuts on track. Where accuracy is key, however, a fence or guide can be attached to ensure optimized cutting precision. There is a wide range of circular saws available from 4in. to 7-1/4in. (7-1/4in., for example, refers to the blades diameter), and hand-held to table mounted. Craftsmen, however, can not get too far without needing a lightweight and cordless circular saw to get the job done.
The cordless circular saw is lightweight and convenient eliminating the need for outlets and to lug around endless, knotted ropes of power cord. With its portability and more compact size, the cordless saw can go more places and conveniently conquer your projects with not much sacrifice to power. From commercial jobs to backyard plans, no toolbox should be without this cordless giant.
