Cordless Circular Saws Video
Tim Carter discusses the advantages of the cordless circular saws. They are lighter and don't have to have an electrical outlet available. Cordless saws are available in a variety of voltage options. Tim has both an 18 or 24 volt models. The higher the number, the more power the saw will have.
The cordless circular saw blade is normally smaller then their corded model. However, the 6-1/2" diameter saw blade is still big enough for cutting through those 2x4's and 2x6's.
They make great gifts. Or maybe yet, buy one for yourself. Cordless tools are the cutting edge.
