Orbital sanders are hand-held tools that work by rotating themselves elliptically to create a smooth surface. You can even use them to remove rust or paint. If you need a smooth surface in a short time, an orbital sander might be your best bet.
The DeWalt DWE6423 5 in. Variable-Speed Random Orbit Sander comes with a hook-and-loop pad to make changing sanding sheets simple. This random orbit sander has a powerful 3-Amp motor that delivers between 8,000 and 12,000 OPM. The separate counterweight reduces vibration while the rubber overmold grip provides comfortable sanding.
In general, there are some things to keep in mind before you start your project. It is best to apply even pressure across the pad of an orbital sander. This ensures there will be no divots and swirls on the flat surface you are working on. Before you begin working with an orbital sander, be sure to wear a dust mask and protective glasses to keep yourself safe. Work in a well-ventilated area, and remember to empty your sander's dust bag before using it or connect the sander to a vacuum or dust collector.
