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, framing, and trim work. There are different types of miter saws, including compound miter saws and sliding miter saws. Compound miter saws can tilt to make bevel cuts, while sliding miter saws have a sliding feature that allows for wider cuts. These tools are essential for achieving accurate and clean cuts in various projects.
