From simple to more advanced DIY fabrication projects, sanding has been an important finishing process, to really drive home the final product’s appeal and get rid of jaggedness or roughness. Before the invention of powered sanders, sanding was predominantly done by hand.
Manual sanding was however only feasible for workpieces with small areas and was very time consuming for larger surfaces.
The invention of the powered sander revolutionized the sanding process, allowing large surfaces to be smoothened quickly and effectively, without much strain on the operator. There are now over 12 types of powered sanders on the market, with each tailored to a specific area of application.
Of all the available types, the orbital sander really revolutionized powered sanding, and tackled some of the problems associated with its predecessors; its unique design allows for a much smoother finish.
When scouting for an orbital sander, you want the best your money can buy. With so many brands out there, however, this can be a quite daunting task.
So, how do you choose the best orbital sander for your projects?

Orbital Sander Buyer’s Guide
What is a random orbital sander?
If you are familiar with woodworking, then you will, at one point or the other, have had reason to work with an orbital sander. Sanding, no matter how unpleasant, is one essential task we have to carry out, so the end-product from the long hours of hitting the nail on wood can be worth looking at.
Sanding blocks and sandpaper are the traditional means of smoothening surfaces, but they can be quite inefficient and time-consuming. With a random orbital sander, you can create smoother surfaces in a considerably lesser period – that, with minimum effort too.
A random orbital sander is a power tool which employs repeated simultaneous random circular motions, and elliptical loops to create smooth surface finishes on a piece of material, notably wood.
A typical orbital sander comprises a sanding pad to which a sanding disc is attached for surface finishing.
Random orbital sanders are quite popular among carpenters, furniture makers, and other woodworking professionals due to their ability to generate super smooth finishes with no swirl patterns.
Parts of a random orbital sander
A random orbital sander comprises several components, each working in tandem to ensure you get the smoothest of finishes. Some of the more prominent parts of a random orbital sander include:
This is the part of the orbital sander that carries out the primary sanding process. Sanding pads rotate and oscillate on the workpiece, generating a super smooth surface finish in the process.
Apart from its use in sanding, a sanding pad can carry out a wide variety of other processes, including polishing of wood, and removal of vast amounts of wood. All this is made possible by the attachment of a sanding disk to the sanding pad.
While scraping away your wood surface with a sander, there is usually an accompanying production of wood dust. This wood dust can make it very difficult for you to continue work, and it can get tiring, having to pause your work at intervals to blow off the dirt. It is to this effect that most random orbital sanders feature a dust bag.
This dust bag is connected to the sander via a vent located on the body, and it collects wood particles that are produced as you work. Just like some sort of vacuum cleaner.
The D-handle is on the body of a sander and allows you to turn and twist it comfortably. The barrel grip, on the other hand, protrudes from the body of the sander and is most times the second option when sanding.
For complete ease of use, most random orbital sanders also feature a palm grip located on top. This palm grip is quite convenient to use, and it relieves the stress on your hands when working for long periods.
As there is a vent on a sander designed to collect wood dust, so also is there a lip seal designed to keep wood particles from entering the sander. Wood particles entering your sander at will can clog up the engine of the sander, and cause considerable damage; hence, why this feature is essential.
The lip seal also acts as some sort of obstacle between your hands, and the sanding disk, which helps to keep you safe while working.
The job of a power switch is quite simple. It’s the only function is to either turn the sander on and off whenever you want to work, or you are done sanding – your choice, boss.
How does a random orbital sander work?
To fully understand the workings of a random orbital sander, you need to get familiar with the parts of the equipment. As itemized earlier, the main components of a random orbital sander include the:
- Sanding pad (or sanding disc).
- Body – which houses the motor.
- Palm grip.
- Dust bag.
- Power cord (if it’s a corded sander).
- Lip seal.
- Power switch, among others.
In orbital sanders, smooth finishes are produced by the circular motion of the sanding pad, but a random orbital sander works in a slightly different manner. Apart from the customary circular motion present in an ordinary orbital sander, a random sander also employs forward and backward strokes to generate even smoother finishes.
To use a random orbital sander, you don’t have to do much. The equipment features a cleverly designed oscillating disc with tiny holes for the attachment of sandpaper.
Once you plug in the sander – that is, if you are using a corded sander –, and you turn it on, the motor begins to spin the sanding pad. At the same time, the sander itself moves in a completely circular motion.
These series of motion make the pattern with which the sanding pad moves completely random, thereby helping to eliminate the swirl designs familiar with simple sanders. To convert this motion into finishing, you simply push down the equipment on the surface of the workpiece and make repeated movements with your hands.
While sanding, take care not to apply too much pressure on the equipment, as this wears out sandpaper faster, and increases the risk of wearing out your motor. Also, concentrate your initial sanding efforts on the center of your workpiece, and save the edges for last. This is because your sanding pad might get caught and damaged on a sharp side.
The above is basically how a random sander works, but there could be more to a particular product. Hence, that’s why we strongly advise that you take the time to properly read through and digest the contents of your sander’s instruction manual. Each random sander is likely to have slightly different features to others, hence your knowledge of one might not necessarily work for another.
Who needs a random orbital sander?
Random orbital sanders are quite versatile and can be used in a series of operations, but the main idea behind an orbital sander is the removal of unwanted surfaces. That being said, a random sander is a perfect tool for people who need to carry out one or more of the following operations:
Removal of metal rust
A random orbital sander can be used to clear up rusty surfaces. To do this, a sanding disk that is tougher than average has to be affixed on the sanding pad. Also, a sander shouldn’t be used repeatedly for this, as prolonged usage can lead to damage of the equipment.
You can make almost any surface squeaky clean with the aid of your orbital sander. What you just need to do to achieve this is, attach a foam-like sanding disc to your sanding pad, and then use your equipment on such surface.
What makes the random orbital sander even more suited for this is the fact that using one won’t leave swirl marks on your surface – You can make that rough car bonnet shine again with your random orbital sander.
With your random orbital sander, you can reduce the size of wood to a considerably lesser amount. To do this, you need to use your equipment continuously on the same surface, until the desired size is attained.
After coupling materials together, you can transform the rough edges in the finished work to smooth edges, with the aid of a random sander.
Things to consider when buying a random orbital sander
After making up your mind to buy a random orbital sander, the next thing to do is select a brand and product capable of handling your workload. However, given the glut of sanders out on the market, this might prove to be an unexpectedly arduous task.
There are certain features and qualities you need to look out for to make your task of choosing the right orbital sander easier. This is so you can be confident you’ll be selecting a piece of equipment capable of handling the rigors of sanding you’ll throw at it. Some of the qualities you should consider when purchasing a random orbital sander include:
Dust control feature
Most random orbital sanders boast a built-in dust bag feature, but for a more efficient cleaning job, go for a sander with a vacuum hose connector. These connectors are compatible with the standard nozzle types for vacuum cleaners, and they allow the filter to pick wood particles created during sanding directly. With this, your work area will be consistently rid of dirt, and your lungs will thank you.
The engine size of your sander is an important quality that directly ties to the quantity of work it can perform without crashing and burning. This is one quality you should give utmost priority when shopping for a sander.
The motor is the powerhouse of the sander, and it affects a lot of things, but none as important as the rate at which the sanding pad orbits. Sanders, with high power ratings, can work at high speeds, consequently generating smoother finishes. Those with lower amp motors do not move as fast, and as a result, do not produce finishes as good as the high-class sanders.
If you’re buying a sander for large-scale or commercial use, it would be best if you went for one with a large motor size. However, if the sander is intended for strictly domestic purposes, you don’t need to go all out, and you will be okay with a small capacity sander.
Sanding disc size
The size of the sanding pad and the way it is laid out on the sander also plays a massive role in the performance of a random orbital sander. When buying a random orbital sander, make sure the pad is big and powerful enough to carry out the tasks you intend to.
Ease of use
Any sander that will be worth your while should be easy to use and have features in place that prioritize your comfort while operating it. The sander, as well as its instructions manual, should not be difficult to comprehend. Also, the sander should be reasonably easy to operate, and its handle built in a way that it doesn’t slip off easily while in use.
The sander should also have measures in place to reduce the typically annoying vibrations that occur while in use, as this will reduce errors, and motivate you to work for longer.
Also, some random orbital sanders have a simple hook-and-loop feature, which makes it super easy for users to take out, and replace worn-out sandpaper. With this method, you simply peel off the used sandpaper and fix the next one. You can also reuse sandpaper, provided they are not completely damaged.
Variable speed knobs
The key to achieving smooth surfaces and finishes is to have control over your sander’s speed, and you can do just that with the aid of variable speed knobs. Variable speed knobs make it possible for you to tinker with sanding speed and adjust sanding aggression.
Therefore, if you are a sucker for perfection or you want to create a specific type of surface finish, it would be best if you went for a random orbital sander with speed adjustments.
Length of Power Cord
The length of the power cord is an essential factor that affects mobility when you’re working with an orbital sander. If you’re going for a corded sander, this is an extra feature you need to consider.
Longer power cords mean you can work farther away from your power source; hence, you have greater mobility and comfort. With short power cords, you can only use your sander within a limited range, and you’ll most times have to move your workpiece closer – which is not an ideal situation if the workpiece is relatively large.
Kinds of Random Orbital Sanders
Random orbital sanders in the market today fall under two distinct categories, based on where they get their power. These two groups of sanders are Electric orbital sanders and air orbital sanders.
Electric orbital sanders
These types of orbital sanders draw the energy to work from an electrical source, which can either be a battery or a power outlet. As a result, electric sanders are further subdivided into corded and cordless sanders.
Corded sanders come with a power cable, and need to be plugged into a power outlet before they can be used for any form of woodworking. Cordless electric orbital sanders, on the other hand, work with lithium-ion batteries and require constant recharging for you to continue working with them.
Electric orbital sanders are suitable for a wide range of finishing products, but of course, you only get what you pay for. If you want a high-end electric sander capable of executing large projects with relative ease, be prepared to pay a premium price. For basic DIY tasks in and around the home, a simple electric sander is all you need.
Air Orbital sanders
Air orbital sanders, in contrast, do not depend on electricity to work. They function with the assistance of an air compressor device, which converts electrical power into energy needed for them to run. As a result of this, orbital sanders tend to be generally more powerful, and more expensive compared to electric sanders.
Also, orbital sanders can be further categorized based on the method of operation. If you are to buy a sander based on this grouping, you will end up with either a handheld orbital sander or an orbital floor sander.
Handheld orbital sanders
This kind of random orbital sander is typically small and can be held and operated using one hand. Most electric and air orbital sanders are handhelds.
A handheld orbital sander is best suited for domestic use and in small-scale smoothing operations. Due to their sizing, and affordability, handheld sanders are the most popular kind of sanders available on the market today.
Orbital floor sanders
Orbital sanders, in contrast, are large equipment that cannot be operated using one hand, and they are commonly used in floor finishing – with your two hands pushing like in a mower.
One significant advantage of using an orbital sander for floor finishing is that the circular motions of their sanding pads do not leave swirl marks on the work surface; thereby, ensuring you get the smoothest of finishes.
Cordless vs. Corded Sanders
The power supply is a significant determinant of how you’re going to enjoy working with your random orbital sander. After all, of what use will it be, if you buy a sander, only for you not to be able to use it due to erratic power supply. And then, at the end of the day, you have to revert to manual finishing using sandpapers. That would be quite a waste, I must say.
Before buying any sander machine at all, you need to observe and determine the rate of power supply to your area. If the power supply in your area is steady, a corded random orbital sander would be perfect for you. Corded sanders work only when their power cord is connected to an exclusive power outlet designed for them.
Because corded sanders have a short, inextensible power cord, they can only be used within a specific range, and are not ideal for site work. They are, however, particularly suitable for people who spend hours working on the same spot.
Cordless random orbital sanders, on the other hand, do not have a mobility issue and can be used anywhere, at any given time. These types of sanders employ a battery for power generation and have to be recharged from time to time during prolonged usage.
Cordless sanders do not generate as much power as their corded counterparts. As a result of this, they are not quite able to replicate the same neck-breaking sanding speeds typical with corded sanders. Also, factor in the amount you have to spend on buying batteries for cordless sanders, and you’ll realize it might be better if you go with a corded one.
FAQs related to random orbital sanders
What is the difference between a random orbital sander and an orbital sander?
The main difference between a random orbital sander and an ordinary orbital sander is the motion of the sanding pad when the equipment is in use. For orbital sanders, the sanding pad creates smooth finishes by merely moving in a circular direction only. While in a random orbital sander, the sanding pad turns in small elliptical loops as the equipment itself moves in circles.
Is an orbital sander suitable for wood?
Orbital sanders are the ideal tool for generating smooth finishes and curved edges on wood, but they are just not that good for removing paint or varnish stains from wood. This is due to the typically small sanding pad found on orbital sanders, which makes them unsuitable for use in sanding large pieces of wood.
Can you use an orbital sander on drywall?
Yes, you can use an orbital sander to smoothen drywall to achieve an even surface. To do this successfully, use only a 150 or 180-grit sandpaper. Also, you should not let your equipment linger too much on the spot, else the sandpaper will ruin the wall.
Should I use a drum or an orbital sander?
When refinishing the hardwood floor in your home, your choice of a sander depends on the type of finishing you intend to achieve, your level of expertise, and the present condition of the floor. Once you have answered those questions, you are left with one fundamental question: what kind of sander do I use? The two types of sanders utilized for this are the drum and orbital sander. If the floor in your home is completely damaged, and in need of several layers of aggressive finishing to become pleasing to look at once again, your best bet is a drum sander. On the other hand, if you need just a slight retouching of your floor finishing, an orbital sander is what you should use. If you're also short on time, you should work with a drum sander. They cut pretty quickly due to the aggressive movements of their sanding pads. Conversely, if you have all the time in the world, you should go with an orbital sander. Operating an orbital sander requires less physical effort on your part, but it might take extended periods to complete work.
Why do orbital sanders have holes?
Orbital sanders have holes to successfully extract the dust particles produced while sanding – think of it as some sort of ventilation system. Dust passes through the holes, usually found on the sanding pad, and into the dust bag. Hence, that's why you must buy sanding discs with holes to match those on your equipment.
Are all orbital sanders random?
Not all orbital sanders employ random movements in their operation. Orbital sanders, in general, work via a series of repeated circular motions only. However, it is those that take a step further and employ two different types of unrelated movements that are classified as random orbital sanders.
What is the difference between a sander and a polisher?
The main difference between a sander and a polisher is the surface with which they work. A sander is built primarily to convert rough surfaces into smooth finishes, while a polisher takes an already sleek exterior, and refines it further to give it a glossier appearance. Also, polishers work with a much slower spin rate, as compared to sanders. This makes the polisher much better for detailing.
How fast should a random orbital sander spin?
There is no standard speed for a random orbital sander to spin. What does affect the surface finish is the rate at which you move your sander across the work surface. You should allow the sander to rotate freely under its own weight so that the orbital action will work as it should.
How heavy is an orbital floor sander?
An orbital floor sander, on average, can weigh up to ninety kilograms – they are called floor sanders for a reason! They are unsuitable for amateur sanders and can cause a lot of damage when not used properly.
Can I use an orbital sander on hardwood floors?
You can indeed use an orbital sander to finish hardwood floor, but you sure are going to put in tons of effort, time, and determination. Orbital sanders are typically created to work on softwood, but will work on a hardwood floor if you exert an appropriate amount of pressure while working.
