As I am sure you are all aware, using the proper tool on your project can save you time, as well as giving your project that professional look we all desire. It's for this reason that this month, I'm going to discuss random orbit sanders.

Random orbits are relatively new to the market, having been known as DA's or dual action sanders in the older pneumatic version. What random orbits effectively did was to revolutionize finish sanding. Before random orbits existed, the finishing phase was completed with both 1/4 sheet and 1/2 sheet finishing sanders. These machines were orbital, and gave your project a nice, clean finish.

Random orbits work on a system just as their name states, they random each orbit. Instead of a circular motion, these machines follow almost a figure eight motion. Because of this motion, you will be left with a swirl free finish, something you couldn't achieve with conventional finishing sanders.

There are two basic types of random orbits on the market today. The first is the larger and more aggressive right angle models, and the other is the smaller palm grip model. Let's go into some detail on both.

The right angle models are, for the most part, available in either 5" or 6" versions, and most offer variable speed, a feature that will help when finishing surfaces that tend to burn when finished at faster speeds. Most are available with either PSA or hook & loop pads, for use with either sandpaper system. These machines, when used at the faster speeds, can be very aggressive, and can be used to take down stock. When used at slower speeds with very fine sandpaper, they make great finishing sanders.

The little palm grip units are strictly used for finishing applications. In most cases, the finer the sandpaper, the better the finish. Your finish will be swirl free, and these sanders are extremely user friendly. A wonderful feature of most, is a braking system for the pad, which will prevent the gouging of your material. The way it works is that the pad doesn't pick up speed until after it makes contact with the surface to be sanded. This make these sanders incredibly easy to use, whether you're just starting out in the hobby, or a master woodworker.

As far as the different features are concerned, most of these tools are available with either PSA or hook & loop pads, most offer dust extraction, as well as variable speed, which can be an added plus.
