Frequently Asked Questions
What is a belt sander used for?
Belt sanders are used for a variety of applications needing high-speed, high-capacity sanding. They are commonly used to precision sand to a scribe line for a perfect, smooth cut or to sand down rough, uneven surfaces.
Belt sanders rapidly remove layers, so they are perfect for covering large areas quickly. If you need to refinish a floor, for example, a belt sander would be ideal. However, they can also be used to reshape material or rough sharpen tools like axes and shovels.
Belt sander vs orbital sander – What’s the difference?
Belt sanders and orbital sanders are both high-speed power sanders but have slightly different designs and applications. While a belt sander uses a running loop of sandpaper, orbital sanders use spinning sandpaper discs.
Because of their greater ability to finesse difficult corners, odd angles and round edges, orbital sanders are better for detailed work on small areas, such as furniture. However, because of the swirl marks they leave, surfaces usually requiring finishing after sanding to improve the look.
Belt sanders are more powerful than orbital sanders so they are ideal if you have high capacity sanding needs for large, flat surfaces. If you need to strip off a lot of wood, belt sanders will perform better than orbital sanders. The belt run also benefits the aesthetics, as the sanding pattern aligns with grain to retain the natural look of the wood.
