Abrasion is the key to many a finishing job, and electric sanders provide plenty of abrasion. The idea is simple enough: abrasive sandpaper is applied to a rough or grainy surface in order to smooth it out. Anyone who has done their share of manual sanding knows that it’s quite the workout—enter the electric sander. These popular powerhouses can be found in a range of styles and designs, including palm, drum, cordless and oscillating electric sanders. Looking for other sanding options? Choose from hand sanders, belt and disc sanders, and orbital, random and triangle sanders.
