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 sanding edges, surfaces, and contours. These tools come in various sizes and can be stationary or portable. A stationary disc sander is typically mounted on a workbench, while a portable version can be easily moved around. Safety features, such as guards and dust collection systems, are often included to protect users and maintain a clean workspace.
