What is a circular saw?
A circular saw, sometimes called a power saw, is a powered device that cuts with a rotating blade. Next to hammers and drills, circular saws are the most commonly used tools in home building and repair. Interchangeable blades on circular saws allow you to cut everything from lumber to concrete. Circular saws have an electric or battery-operated motor that spins the blade. On some circular saws, this motor is mounted perpendicular to the saw blade. These circular saws offer a greater deal of control and reduce the chances of binding or a kickback, which can occur when the circular saw’s blade jams up in tough material. The price for the extra control is reduced cutting power. For heavy-duty cutting, such as thick pine or hardwoods, a circular saw with a motor mounted parallel to the blade is ideal. These circular saws offer more torque directly to the blade and some models include geared speed settings.
