There are so many different kinds of sanders that one might get confused about which they are supposed to use. You can be doing sanding for fun or it might be a part of your job but the important thing is to have the right kind of sander for your projects because sanding matters a lot and it determines the look of your finished product. You can never complete your project with the wrong kind of sander because you would end up ruining it. If you can could use any sander for sanding then there would not be so many different types available. If you already have a project at hand and you need the end product to have a smooth and fine surface then your best bet is to get a random orbital sander.
The best random orbital sander for woodworking would allow you to finish a product or item in such a way that there would be no marks of sanding on it which is something that cannot be achieved with the other sanders. The reason that a random orbit sander is able to do that is because it has a circular disc for a sandpaper and the sanding is done in not only a circular motion but also in a back and forth motion which helps to create the perfect surface of the object. The circular motion is what is necessary to avoid swirl marks which are a common result of sanding. A random orbit sander is preferred by a lot of professionals because it can sand with and against the grain which is quite uncommon among sanders. It also has a dust bag that is used to collect all the dust that comes out during the sanding.
