A circular saw is a versatile power tool that is commonly used by carpenters and cabinet makers to make various cuts. This tool has a round blade that is equipped with sharp metal teeth which spin to cut through materials effortlessly. With the right blade, it can cut through a variety of materials, including lumber, timber, paneling, and concrete board, as well as sheet metal. Many circular saws allow operators to adjust the depth and height of the cut and make bevel cuts. The circular saw comes in two types: handheld and table-mounted. Handheld saws can be either left-handed or right-handed for ease of use, while table-mounted saws provide more stability and control.
