A sander is a power tool used primarily for smoothing and finishing surfaces, particularly wood. It is equipped with an abrasive material, usually sandpaper, that rotates or moves in a back-and-forth motion to remove unwanted material from the surface being worked on.
The main purpose of a sander is to eliminate scratches, rough edges, or uneven surfaces on various materials, revealing a smoother and more refined finish. Sanding is commonly performed on furniture, floors, cabinets, doors, and other wooden objects, although some sanders can also be used on metal or plastic surfaces.
Different types of sanders are available to suit various applications. The most common types include belt sanders, random orbital sanders, palm sanders, detail sanders, and disc sanders. Each type has specific features and uses, ranging from heavy material removal to delicate finishing work.
Sanding can be done on flat or curved surfaces, depending on the tool and the nature of the material being worked on. This process helps prepare the surface for further treatment such as painting, staining, or varnishing by providing a clean, smooth base.
In summary, a sander is a versatile power tool used for the mechanical abrasion of surfaces, primarily wood, to achieve a smoother finish by removing imperfections and creating a more refined appearance.
