A power sander is a tool used to smooth surfaces by abrasion. It typically uses sandpaper attached to a motorized base, which moves the sandpaper rapidly to remove material from wood, metal, or plastic. Common types include orbital sanders, belt sanders, and detail sanders, each designed for specific tasks and finishes. Power sanders are popular in woodworking and construction for their efficiency and ability to produce a smooth finish quickly. They can be used for various projects, from furniture refinishing to preparing surfaces for painting. Proper safety precautions, such as wearing a dust mask and safety goggles, are essential when using these tools.
