DIY Frequently Asked Questions / Random Orbit Sander')">
Uses a round disc of sandpaper to sand in both a circular and back-and-forth motion, which reduces swirl marks.
Common sizes are 5” and 6”, but smaller and larger sizes are available.
Sands in all directions, both against and with the grain.
One of the biggest differences in these sanders is the grip style a manufacturer may use. Some have grips at the front of the sander, while others have handlebars that can be attached at either side of the sander.
Another important feature is variable speed for slower, delicate work or faster, heavy work.
