A miter saw is a power tool used for making precise crosscuts and angled cuts in wood and other materials. It features a circular blade mounted on a swing arm that pivots left or right, allowing users to cut at various angles. Miter saws are commonly used in woodworking, carpentry, and construction for tasks like framing, molding, and trim work. There are different types of miter saws, including compound miter saws and sliding miter saws. A compound miter saw can tilt to make bevel cuts, while a sliding miter saw has a sliding feature that allows for wider cuts. Both types enhance versatility and accuracy in cutting tasks.
