A drum sander is a woodworking tool used to smooth and finish surfaces, particularly large flat areas like floors and tabletops. It features a rotating drum covered with sandpaper that sands the wood as it moves across the surface. This tool is efficient for removing material quickly and achieving a uniform finish. Drum sanders come in various sizes, from portable models for small projects to larger, industrial versions for professional use. They are often used in conjunction with other tools, such as belt sanders and orbital sanders, to achieve the desired surface quality in woodworking projects.
