However, there are still a few factors that we want to go over with you before you make your final choice. This list of shopping criteria will help you make the best purchase possible.

Power Supply

Rotary sanders can be used in two different ways. Some need to be plugged into a power supply in order to work. If this is the case with the tool you purchase, we recommend purchasing an extension cord as well. Others run on rechargeable batteries. These are much more portable but are also more limited than the type that is plugged into the wall because you will only have a certain amount of time to finish the task at hand.

Dust Bag

To make cleanup easy, many people prefer a rotary sander that has a sandbag included. This sandbag will pick up the wood chips and dust as you sand. All you have to do is detach the bag and throw away the waste inside. If this sounds nice to you, make sure that your rotary sander includes a dust bag. Always read the product’s description thoroughly.

Size of the Sanding Disc

Rotary sanders use discs of sandpaper that come in different sizes. The size you need will depend completely on the task at hand. With a large disc, you can sand larger areas much faster than if you use smaller discs. On the other hand, smaller discs are great for smaller tasks or smaller surfaces. These often weigh much less.

Adjustable Speed

When looking for a rotary sander, you should choose one that has adjustable speed. This option will help you accelerate or slow down the speed of the sanding pad depending on the type of material that you are working on. This factor is extremely important and will allow you to control the sanding rhythm.

If you need to shave down a considerate part of the surface, you can turn the speed up. If, on the other hand, you are sanding a thin surface, your floor or wooden furniture, for example, you can lower the speed to be able to control how much you shave down.

Vibration Control

All sanders make a lot of vibration, and a rotary sander is not an exception. This tool spins around and at the same time produces vibrations. This is why some models come with a vibration control option. This function is useful and extremely important because it will make the tool much more comfortable to use.

Pad System

You will often need different-sized pads when working with a rotary sander. You will probably have to change it quite often, for example, when you need a different size or when then pad you are using wears down. These tools often use velcro to attach the pads to the machine but make sure in the product description. It is important to be able to change the pads easily when working with this machine.
