Random-Orbit Sanders

Random-orbit sanders have circular pads that move/vibrate in a circular motion with a random pattern. The random pattern lets the user move the sander in any direction on the material being sanded, even across the grain, without marring the material surface.

This is the “safest” type of sander and it is one of the best available multi-purposes sanders; this makes it an excellent choice for the occasional user. Most random-orbit sanders necessitate the use of special sand paper designed for the brand and/or model of the sander being used.

Sheet Sanders

Sheet sanders come in models that make use of 1/4 or 1/3-sheets from standard-sized sheet sandpaper. Some sheet sanders make use of specific sand paper with adhesive or velcro to attach the sand paper on the sander. Other models are able to use any type of sheet sand paper.

Obviously, the latter type of sheet sander is more flexible for the everyday user. Unlike the random-orbit sander, the sheet sander moves the sand paper in a single direction, so sheet sanders have to be moved along the direction of the grain of the material being sanded to avoid marring the surface. Like the random-orbit sander, sheet sanders are very versatile and they can be used on a lot of different types of projects.
