What is the difference between an orbital sander and a random orbital sander?
The main difference is the sanding motion. An orbital sander moves the sandpaper in small orbits, while a random orbit sander combines orbital and spinning motions, resulting in a smoother finish with no visible sanding marks. Random orbital sanders are more versatile but slightly more expensive.
Can I use a sander for polishing surfaces?
Yes, certain sanders like random orbital sanders can also be used for polishing surfaces with the appropriate polishing pads and compounds. They are popular choices for automotive polishing or restoring shine to metal surfaces.
Do I need to remove dust between sanding grits?
Yes, it is crucial to remove dust between sanding grits. Dust particles can get trapped in the sandpaper and scratch the surface when moving to a finer grit. Use a vacuum or a tack cloth to clean the surface before switching to a different sanding grit.
Can I use a sander on wet surfaces?
Most sanders are designed for dry sanding. Using a sander on wet surfaces can damage the tool and pose safety risks. If you need to sand wet surfaces, look for sanders specifically designed for wet applications.
Are cordless sanders as powerful as corded ones?

What is the average lifespan of a sander?
The lifespan of a sander varies depending on the brand, quality, and frequency of use. With proper maintenance and regular cleaning, a good-quality sander can last for many years. It's advisable to follow the manufacturer's recommendations for maintenance and replace any worn-out parts.
Can I use sanders for drywall sanding?
