• 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.
• Most use a dust bag to collect sanding dust.
