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 projects. There are different types of miter saws, including compound miter saws, which can tilt the blade for bevel cuts, and sliding miter saws, which allow the blade to slide forward for wider cuts. These tools are essential for creating clean, accurate joints in projects like frames, moldings, and furniture.
