10 Best Random Orbital Sanders Of 2021 [ Reviews And Guide ]

The 10 best random orbital sanders

Last updated on September 20th, 2021 at 05:22 pm

Of all the activities it takes to complete your woodworking or metalworking projects, most folks will agree that sanding is one of the most difficult and unpleasant one of them all. With a random orbital sander however, you can take the difficulty out of it and approach it with ease.

A random orbital sander does not only make your projects easier, but also helps you produce the best surface finish.

The way it works is very simple but very effective. When it’s switched-on, the motor inside it rotates a 5 or 6 inch circular sanding pad attached to an offset bearing.

Apart from rotating the circular pad, it also vibrates it constantly in tiny orbits. This constant rotation plus vibration of the circular pad causes it to move in random or constantly changing orbits. Hence, the name random orbital sander.

This random orbital motion ensures that the circular sanding pad does not follow the same part twice. That is why it will not leave any noticeable circular pattern or swirl mark on the material surface.

In this article, I’ve reviewed the 10 best random orbital sanders, and I’ve also written a comprehensive buyers guide to help you choose the best for your application.

Before going any further, it’s important you know that it is different from an orbital sander.

The most obvious difference between the two is that an orbital sander uses a square sandpaper while a random orbital sander uses circular sandpapers.

However, random orbital sanders are the better of the two because they produce a smoother and better finish due to the random unpredictable movement of the sanding pad.

They are also more aggressive, hence they are preferable when more material needs to be removed or sanded off.

Here in this article, I’ve listed 10 of the best random orbital sanders so you can choose the right one for your sanding projects.

How to Choose the Best Random Orbital Sander

There are many types, manufacturers and brands of random orbital sanders out there. If you want to choose the best one for your project, here’s what you should look for.

Variable speed

When shopping for a random orbital sander, it is recommended that you get one with variable speed. The variable speed option actually helps you to either speed up or slow down the motion of the sanding pad, depending on the type of material you are sanding and the type of finish you want to achieve.

It is very important because it helps you dictate the pace at which you want to sand and the amount of material you wish to remove.

If you need to remove a lot of material from the surface, then you increase the speed. On the other hand, if only light surface sanding is required, like when you want to refinish your wooden floor or furniture, then you can reduce the speed to match the amount of material you wish to remove.

So, get a random orbital sander with the variable speed function for a more versatile sander.

Vibration control

All types of sanders make a lot of vibration, whether belt, disc or orbital sanders. And random orbital sanders are not different.

A random orbital sander is a tool that both rotates and oscillates a circular disc at the same time. Thus, it really produces a lot of vibration.

That is why some orbital sanders are equipped with the vibration control feature to help reduce this vibration and increase user comfort.

For instance, the Bosch ROS65VC-6 is one of such random orbital sanders fitted with a vibration control suspension system that helps reduce the vibration produced by the tool, thus making the tool more comfortable to use for longer periods of time.

So, when shopping for a random orbital sander, this is one useful feature you can take into consideration.

Dust Collection

Dust collection is a very important issue when it comes to sanders in general. A lot of dust is produced when you sand a piece of wood or metal.

So it is important that the dust produced is collected efficiently, so that it will not be on the work surface and certainly not in the air for you not to breathe it in and cause respiratory health problems for yourself.

The sander will not work efficiently if the dust being sanded off is not being removed simultaneously from the work surface.

If the dust is still on the surface, then the sander will not be contacting the wood directly, meaning you will be sanding wood and dust together at the same time, which will ultimately wear out the sandpaper faster, make the sander less effective and cause you to do more work.

So, get a sander with good dust collection. If you have a tool actuated dust collector, fine. Connect it to your random orbital sander so that as soon as you switch on the sander, the dust collector will switch on automatically to collect dust produced by the sander.

If you don’t have a tool actuated dust collector, you might consider getting one or stick to the one you have, provided it collects dust efficiently as soon as it is produced.

Good dust extraction from surface in order to sand the wood, not wood and dust, making sander less effective. Longer abrasive or sandpaper life. Connection on the sander should be compactable with vacuum nozzle.


If you’ve only be sanding horizontal surfaces, like when you are sanding a floor, the weight of your random orbital sander might not be a big issue to you.

On the other hand, if you are sanding vertical surfaces like the side of your kitchen shelve or other vertical furniture that require that you move your sander up and down vertically, then the weight of your sander will come to effect pretty quickly.

In this instance, too much weight can easily create fatigue and tiredness in your arms, thereby shortening the time you can sand with the sander, and ultimately reducing your output.

So, go for as less weight as possible. Your arms will thank you for it.

Changing sanding grit paper

It will be quite unusual to use one sandpaper or one grit size of sandpaper from the start to the finish of a project.

You’d definitely be swapping out different sandpaper, maybe after one wears out or maybe when you need a different grit size for a better finish.

Hence, the ease at which you can swap out this sandpaper is very important. The easiest way to remove and attach sandpaper to the sanding pad is through hook-and-loop.

So get a sander that accepts hook-and-loop sandpapers so that you can easily swap out sandpapers and reduce tool downtime.

Good grip

A random orbital sander is something that needs a good grip from your hands. You need to be able to hold your random orbital sander in your hands and feel comfortable with it over a long period of time.

So, if possible try to hold the sander first and feel how comfortable it is in your arms, because the more comfortable one will allow you to work better with it.

Most likely, you’ll be buying online, so what you should check for is one with a rubber grip. The soft rubber grip allows your hands to hold the sander firmly and comfortably.

So, don’t go for one with a plastic grip. A plastic grip can even cause blisters in your hands. Go for a rubber grip to ease the tension between your hand and the tool.

Long cord

This is not necessarily the best criteria for choosing a random orbital sander, but it is also sometime that might be worth considering for some folks.

A long cord will enable you to reach a wider surface with your sander without needing an extension cord.

So, this is something you might also check when shopping for a random orbital sander.
