Random Orbit Sanders
If you’re only going to buy one sander and are looking for the most versatile, then nine times out of ten, you should opt for a random orbit sander.
Let’s take a look at all you need to know about random orbit sanders, from what you need to look out for when making your purchase to how to best use one.
How to Choose Your Random Orbit Sander
While random orbit sanders all work in pretty much the same way, there can be a lot of differences when it comes down to characteristics such as design, power type and weight.
Here’s our guide on how to choose the best random orbit sander for your needs.
Before you start looking at individual models, take a few moments to decide whether a corded or a cordless model would best fulfill your needs.
Cordless models offer greater freedom. You're not confined to only using your sander near a plug socket and you can take advantage of any good weather to work outside - cutting down on interior dust and mess.
Without a power cord, you can enjoy greater freedom of movement, especially when taking on larger projects with a greater surface area.
Many cordless models may require an additional purchase for the battery and charger if you don’t already have any from that range.
You may also need a spare battery for longer jobs, which can push the cost up considerably when compared to a corded model offering similar performance levels.
Corded models, on the other hand, tend to be more powerful and they won’t run out of battery. So, if you often have extensive projects that take up many hours of sanding at high power, then a corded model would be a better choice for your needs.
They are often a less expensive choice, as they do not require the purchase of additional batteries or chargers like cordless models.
In order to make your task go quicker or to take care over more delicate items, variable speed control can be extremely useful.
Furthermore, when you choose a cordless model with variable speeds, you may find it useful to work at a slower speed when you wish to conserve battery power - when waiting for a spare battery to charge up, for example.
Your random orbit sander will be more comfortable to use for longer periods if it is lightweight. However, you will also find that it will be easier to sand more effectively if it has some weight to it.
This will prevent you from having to continually push down over large areas to achieve the results you are looking for.
When choosing a random orbit sander, pay attention to the weight of the model, while also considering your strength and the type of projects you’ll be undertaking.
Paper Attachment Type
Sandpaper pads may attach with an adhesive back or using a velcro style attachment. For better longevity and improved adhesion, velcro fastenings are preferable.
Sanding for any amount of time can leave you with aching hands and wrists, so it’s important to check the quality of the handle before purchasing.
Ergonomically shaped handles with an easy to grip coating are a good choice to improve your comfort and safety.
Check the controls for ease of use. They should be located within easy reach, but not too close so that you risk of hitting them inadvertently. Rotary dials or thumbwheels offer great ways to adjust speed on the go.
Dust Bag/Extractor Compatibility
While the majority of models will have dust bags or boxes that come as standard, they are not always highly effective and you may find that you have to frequently stop to empty them.
If you are taking on any coarse sanding projects or large surface areas, you will probably want to attach a dust extractor. Consider the availability and cost of compatible extractors for any particular model before purchasing.
It’s not essential, but a carry bag or storage box is a great way to keep your random orbit sander safe when not in use. Also, if you need to transport it, it will make life much easier and will enable you to have all of your essential bits and pieces close to hand.
While an included carry bag isn’t going to be a deal-breaker, it is a nice little extra that will make your workshop more organised and transportation simpler.
What Are the Advantages of Random Orbit Sanders?
Random orbit sanders use a variable rotational sanding motion. As the disc spins, it also moves in small ellipses.
This means that, unlike other types of sander, the abrasive material will not leave swirl marks, as the rotational path continuously changes. This allows you to get that beautiful smooth finish with little hassle.
Things to Look for That Differentiate Random Orbit Sanders
Unlike plain orbit sanders, random orbit sanders have round sandpaper pads instead of square ones.
Whereas belt sanders use sandpaper belts, random orbit sanders take sandpaper pads that attach either with adhesive or, more popularly, with a velcro fastening. Most models have an ergonomic grip handle that is designed to be used with one hand.
On the whole, they are generally fairly compact models with a low center of gravity to make them more maneuverable and comfortable to hold.
What's the Best Way to Use Your Random Orbit Sander?
Random orbit sanders can be slightly more difficult to control than standard orbit sanders.
Always read the accompanying manufacturer’s usage instructions for your product and protect yourself with gloves, goggles and a mask.
Start your sander away from the material, then place it down and move it in the direction of the wood’s grain.

Belt sanders are generally used to strip back finishes over large areas. They tend to be fairly heavy duty and are best used for coarse sanding.
So, if you are looking to sand back a floor or a tabletop, then a belt sander will be the right choice for your needs.
Here’s how to pick the best belt sander and some of their most important features.
How to Choose Your Belt Sander
While most belt sanders are built to a standard design, there are certain features that you should look out for to ensure you choose the best belt sander for your needs.
The higher the wattage, the more powerful your belt sander will be.
If you don’t have much experience or are looking to complete medium-sized jobs, a lower wattage model could actually work to your advantage. This is because some of the more powerful models can sand fairly aggressively, leaving you with lines that you will need to sand out.
However, for large tasks like stripping back the finish on a wooden floor or a large table, a higher-wattage model is the best choice.
The increased power will allow you to get the job done faster, without the need to keep passing over the same area.
It is important to ensure that your model will have a sufficiently long power cord for the kind of job that you envisage doing. A longer cable will also give you more flexibility over where you can plug in your sander, especially if you are not working at home or in your own workshop.
Make sure that the handles on your belt sander are well positioned so that you will be easily able to control your sander.
You should also check the grip as well as the positioning to make sure that your hands will be comfortable when using your belt sander over a large area. The controls should be within easy reach of the handles so that you can safely stop and start your sander.
Automatic Belt Tensioning System
Pay close attention to any systems that make changing the sandpaper belt easier and faster. This will make your job much easier and can also save you valuable time, rather than having to adjust each new sandpaper belt manually.
Automatic belt tensioning systems are generally safer and a great way to hassle-free belt changes.
If possible, look out for a belt sander with variable speed as this will allow you to adjust the pace to your needs. You’ll find that different densities of wood can be sanded more easily at different speeds.
You may also want to adjust the tempo to get through the coarser sanding stage more quickly, then reduce the speed down for a smoother finish when using finer sandpaper.
If you are planning on using your belt sander on its back, for example to sand the edges of boards or as a sharpener, then you’ll need to make sure that your chosen model has a flat top with no protrusions.
Always follow the manufacturer's instructions for using your belt sander invertedly. Some may require a special fixing kit in order to attach them to your workbench.
Dust Bag/Extractor Compatibility
Most models come with an attached dust box or bag as standard. This will help keep your work area dust-free and reduce cleaning up time afterwards.
As coarse sanding over large areas tends to produce a lot of sawdust, you may have to stop frequently to empty your dust bag.
Check to see if your model is compatible with a dust extractor or vacuum cleaner to remove sawdust without having to stop as frequently.
What Are the Advantages of Belt Sanders?
Belt sanders rapidly remove the finish from wood and are an excellent choice for coarse sanding large areas. They are also frequently used to sand down the narrow edges of boards.
If you are looking to remove a varnish or paint finish from a large piece of furniture or a wooden floor, then a belt sander will get the job done quickly and easily. You can also switch to finer sandpaper belts for a smoother finish as you progress.
Things to Look for That Differentiate Belt Sanders
Belt sanders are easy to spot by their two cylindrical drums and a continuous loop of reinforced sandpaper. They are generally larger and heavier than many other handheld sanders.
You’ll need to use two hands to maneuver your belt sander over the surface of your work area, unlike more compact types designed for one-handed use.
What's the Best Way to Use Your Belt Sander?
When using a belt sander, always pay close attention to the health and safety guidelines from the manufacturer. As belt sanders have a fair amount of torque, always double-check that you do not have any loose clothing, hair or any other items that could become stuck in your sander.
Startup your belt sander and allow it to reach full speed before putting it in contact with the surface you want to sand. Slowly ease it down, making sure that the rear part comes into contact first.
Belt sanders tend to drive forwards fairly rapidly. Be sure to keep yours moving and stop to check on your progress regularly to avoid taking off too much.

Detail sanders, as their name suggests, are used for sanding intricate areas or hard to access parts of bigger jobs.
Compact and lightweight, they are designed for maximum manoeuvrability, giving you added freedom of movement.
Let’s take a look at how to pick the best detail sander and how you should use yours for the best results.
How to Choose Your Detail Sander
When choosing a new detail sander, there are several things worth bearing in mind when choosing the right model for your needs.
As detail sanders don’t need as much brute power as other types of sanders, and they need to be easy to move around, cordless models are preferable.
Time spent on intricate sections may add up, but it is usually at a fairly slow speed which draws less power from the battery. Power cords can be an extra hindrance over tricky sections such as finiales or balustrades, so consider whether or not a cordless model would make your task easier.
The main advantage of opting for a corded detail sander is the price, as corded models tend to be cheaper. This is especially true if you don’t already own any power tools from the same product range with interchangeable batteries.
While a cord may get in your way, if you don’t have a charged up battery ready to go, it’s often more convenient to simply plug-in a corded model and get the job done.
Detail sanders are designed for one-handed use and generally feature straight handles that allow you to angle your sanding blade with precision.
Some models may have handles that sit over and above the sanding plate, making them better suited to tasks such as sanding small flat items of furniture and getting right up against walls.
Ideally, your detail sander will be fairly lightweight so that it is easier to move around and to get into tight spaces.
Corded versions weigh in around one-kilogram, preventing your hand from becoming fatigued and making it easier to angle your sander when accessing hard to reach areas.
Like random orbit sanders, detail sanders may use adhesive or velcro fastening pads. As previously stated, it is preferable to opt for velcro fastening which tends to stay in place for longer and is more durable over time.
When choosing a detail sander, aside from the fastening type, take a look at the availability and cost of extra sandpaper pads.
Sanding Plate Shape
Detail sanders come with triangular-shaped sanding plates, making them look a little like an iron. This shape allows them easy access into tight corners and along edges.
Before purchasing, consider the size and width of the sanding plate and whether it is narrow enough to achieve the level of detail you are aiming for.
Your model should come complete with a dust bag or box to collect sawdust. As detail sanders don’t produce as much sawdust as belt sanders do, and given their compact size, detail sanders dust bags tend to be on the small side.
If you are going to be using your detail sander for long periods of time, you may want to check if it has the option to attach a dust extractor or vacuum cleaner. This will allow you to get on with your project without having to frequently stop to empty your sander.
What Are the Advantages of Detail Sanders?
Lightweight and compact, detail sanders are ideal for taking on small sanding jobs or for completing intricate parts of larger sanding tasks. Their primary advantage is that you can sand hard to reach areas such as tight corners.
Things to Look for That Differentiate Detail Sanders
Detail sanders stand out because of their triangular-shaped sanding plates. They are also more compact and lighter than other types of sanders such as belt sanders.
Designed to be easy to manoeuvre into tight spots and up against walls, detail sanders are designed for one-handed use and they are available as either corded or cordless models.
What's the Best Way to Use Your Detail Sander?
Detail sanders are fairly easy to use. Startup your sander away from your item that needs sanding.
Once the sander is running, simply place it down on the surface, and move across smoothly so as not to create an uneven finish.
