Quick Summary

A belt sander is a portable power tool used for smoothing, polishing, or cleaning surfaces of materials like wood, plastic, or metal. It can also be used to prepare surfaces by roughening them before finishing.1

The belt sander features abrasive-coated belts that run on rollers. These rollers rotate on axes perpendicular to the direction the sander is moved, allowing for efficient material removal and surface preparation. The first known use of a belt sander dates back to 1903.12
