A belt sander is the tool we reach for when we need to remove material quickly and quickly flatten rough surfaces. Whether you are leveling a tabletop, cleaning up reclaimed lumber, or knocking down uneven glue joints, a belt sander saves time and delivers even results.
It matters because no other handheld sander removes stock as efficiently or keeps large surfaces as flat when used correctly. Before choosing a belt sander, consider how much material you typically remove on a project.
Some sanders offer raw power for heavy surfacing, while others balance control with smoother handling. Belt size, weight, speed control, and tracking accuracy make a big difference in how predictable the tool feels during long sanding sessions.
