Name a common type of power sander.

The belt sander is indeed a common type of power sander widely used in various woodworking and finishing applications. It functions by using a continuous loop of sandpaper that is driven by a motor, allowing for efficient material removal from surfaces. This tool is particularly effective for leveling and smoothing large flat areas, making it ideal for tasks such as preparing wood surfaces for varnishing or paint.

The belt sander's design allows it to quickly remove material and can handle rough sanding jobs, which is essential in both professional and DIY contexts. Its versatility makes it a staple in workshops, and the control over the sanding process helps in achieving a smooth finish on various wood surfaces.

While other types of sanders like orbital sanders and hand sanders are also common, each serves slightly different purposes. Orbital sanders, for instance, are great for fine finishing and can be maneuvered easily on curved and contoured surfaces, while hand sanders are manual tools that may not be as efficient for heavier sanding tasks. The belt sander's effectiveness in power applications and ability to tackle larger projects solidifies its place as a fundamental tool in woodworking.
