A random orbital sander is the perfect tool for achieving a smooth, professional finish on your woodworking projects. Because the sanding disk travels in a random elliptical motion, it won’t leave swirl patterns on surfaces and it isn’t as affected by the direction of the wood grain. Sanding disks of various grit attach to the tool using stick-on adhesive or hook-and-loop fasteners. Some models even have a vacuum feature for collecting dust. Random orbital sanders can be corded, cordless, or pneumatic-powered for people with compressors in their wood shops. Choosing the right tool depends on what sort of projects you plan on tackling. Here are four sanders that might be right for you.
