That’s a very common and essential woodworking tool! The term “electric orbital sander” generally refers to one of two main types: Random Orbital Sander (ROS): The most popular type. It moves the pad in small circles and oscillates randomly, preventing swirl marks. This is the best choice for general-purpose sanding, finishing, and polishing. Sheet/Finishing Orbital Sander (Square/Rectangular Pad): Used for fine finishing, particularly in corners or where a less aggressive action is required. It uses standard quarter-sheet or half-sheet sandpaper. orbit sander
