What is the best orbital sander?
There is no single best orbital sander for everyone. For most DIYers, the best choice is a 5-inch random orbital sander with variable speed and decent dust collection, such as the Bosch ROS20VSC or Makita BO5041. If you already own a battery platform (Milwaukee M18, Makita LXT, Ryobi ONE+), the best orbital sander is usually the one that runs on those batteries.
What is the difference between a random orbital sander and an orbital sander?
A random orbital sander spins a round pad while moving it in small random loops, so it removes material faster and leaves almost no swirl marks. An orbital (sheet or finishing) sander uses a square pad that only vibrates in small circles: it is slower but reaches into corners. For most projects a random orbital sander is the better first sander.
Should I buy a corded or cordless orbital sander?
Buy corded if you sand for long sessions or want the most power per dollar. Buy cordless if you already own batteries from that brand, since tool-only cordless sanders cost about the same as corded ones. Starting cordless from scratch costs more because you also pay for a battery and charger.
What size orbital sander should I get?
A 5-inch sander is the standard for DIY and furniture work: sanding discs are cheap and easy to find, and the tool is easy to control. 6-inch sanders cover large flat areas faster but are heavier and harder to handle on edges and small parts.
What grit should I start with on an orbital sander?
Start with 80 grit to remove old paint or varnish, 120 grit on bare wood that only needs smoothing, then move up one step at a time (120, 180, 220) without skipping more than one grit. Finish at 180–220 before staining or painting.
