A palm sander, also known as a finishing sander or quarter-sheet sander, is a handheld power tool used for sanding and smoothing surfaces. It is called a palm sander because it is small and can be comfortably held in one hand. Palm sanders are typically used for light to medium sanding tasks such as removing paint, smoothing rough surfaces, or preparing wood for finishing. Palm sanders are easy to control and maneuver, making them suitable for detail work and tight spaces. They are commonly used by DIY enthusiasts and professionals for woodworking projects, furniture refinishing, and small-scale sanding tasks.
