Buyer’s Guide For The Best Random Orbital Sander

Despite the fact a random orbital sander is a small and compact unit, getting the first one you see isn’t a wise decision. These units are sophisticated and they are designed to be as accurate as possible. All of this should help you understand that you need a proper buyer’s guide in order to get the best product of this kind.

Electric motor power

In this case scenario, more is better. A more powerful electric motor will operate for a longer period of time, it can be used for tough applications and it will offer the highest sanding speeds. There are different possibilities out there, starting at 1 amp and reaching 7 amp or more!

Variable speed control

This is the first factor you will have to consider, but only if you are a professional in what you do. When you have the ability to adjust the speed of the sander, you can use it for smoother and rougher applications. Without this feature, you would have to use a sander for rough, and then your hands for smooth or vice versa.

This is almost a standard feature and almost all models come with it. Yes, some units still have fixed speed which isn’t a great choice.

Size of the sanding disk

All random orbital sanders have a disk which is used to hold the sandpaper in place while sanding. The size of the disk is usually 5 inches in diameter. But, you can find smaller and bigger models as well. It is important to add that smaller random orbital sanders are more suitable for smaller applications.

Vibration level

All sanders will generate some form of vibrations. How well they are capable to eliminate them will make a huge difference. We can see that high-end models almost don’t have any vibrations at all, so they are suitable for long uses. If vibrations are present, you won’t be able to use a sander for longer than 1-2 hours.

Sealed switch

A sealed switch is a mandatory feature to look for. Sanding will generate a lot of dust and some of it will penetrate the on/off switch which will cause a malfunction. If a switch is sealed, then the dust can’t penetrate the inner of the sander, which makes it far more durable.

Dust collection

How well a sander can collect the dust which is generated by sanding will make a huge difference. For example, a model without this feature is almost useless and it can be used for minor applications only. The best random orbit sander must collect as much dust as possible and store it, so there is no dust present while sanding. Some models perform this task better than the others.

2 dust ports

Thanks to the fact you have 2 individual dust ports implemented into the sander, dust won’t be an issue here. You can sand as long as you want and all the dust will be stored in a canister, which is paired with a paper filter.


The Bosch 120-V 6-Inch is the best random orbital sander on our list and the one we will want to recommend for all of you. We give it 5 out of 5 stars due to the fact it is the most sophisticated and the most professional unit we were able to discover. Other models are a great value for money, they are modern as well and they are perfect for most users.
