A drum sander is a woodworking tool designed to smooth and finish surfaces, particularly large flat areas like tabletops and floors. It uses a rotating drum covered with sandpaper to remove material from the surface, making it ideal for leveling and preparing wood for finishing. These machines come in various sizes, from portable models for small projects to larger, industrial versions for professional use. The adjustable height allows users to control the depth of sanding, ensuring a consistent finish. Proper use of a drum sander can significantly reduce the time and effort needed compared to hand sanding.
