A sander is a power tool used to smooth surfaces by abrasion with sandpaper. Sanders have a means to attach the sandpaper and a mechanism to move it rapidly contained within a housing with means to hand-hold it or fix it to a workbench. … It can be used for rough or finesanding depending on the sanding grit used.

The detail sander is a perfect tool for working with difficult projects. … They are even referred to as thumb sanders, because of their size and ability to complete jobs in small spaces. Other sanders such as belt sanders or block sanders take up much more surface area and can damage small detail areas.
