A disc sander is a power tool used for smoothing and shaping wood, metal, and other materials. It features a circular sanding disc that spins at high speeds, allowing users to quickly remove material and achieve a smooth finish. Disc sanders are commonly used in woodworking and metalworking shops for tasks like leveling surfaces and rounding edges. These tools come in various sizes and can be stationary or portable. Stationary disc sanders are often mounted on a workbench, while portable versions can be easily moved around. Safety features, such as dust collection systems, help maintain a clean workspace and protect users from harmful particles.
