There is also a large front grip for comfortable operation as you use the tool. The resultant ease of use is part of what makes this the best overall belt sander on our list.

Our rating is also due to the sander’s auto-tracking belt system, which will track the belt without adjustment and thereby increase the accuracy of the sander.

Types of Belt Sanders

While the belt sander reviews above will give you some idea of the models to go for, there are still some important things about these sanders that you have to know. And key among them is the types.

There are two primary types of belt sanders, which are the handheld and stationary belt sanders. Each has pros and cons and will naturally be more suitable for different situations.

#1. Stationary Belt Sander

As their name suggests, the stationary belt sanders are designed to remain in one place. In other words, the woodworkers have to bring the workpiece to the machine for sanding.

With these sanders, the sanding belt will rest on the top surface of the machine. These sanders will, in most cases, be larger and heavier than the handheld ones.

Some stationary sanders can also be mounted on a workbench. These are the type that woodworkers refer to as bench sanders.

You can use these sanders to sand both wood and metal workpieces. However, their size and stationary nature make them best for large, commercial sanding projects.

#2. Handheld Belt Sander

Handheld belt sanders are the most common type of the two, and they are what you will use for most of your sanding projects.

These sanders come in various sizes and shapes. They are smaller and lighter than the stationary belt sanders. Unlike the stationary sander, the sanding belt on the handheld sander is on the bottom section of the machine.

The location of the sanding belt on these sanders makes them ideal for sanding stationary workpieces like floors.

You’ll find that the size of the belt will vary from one model to the other, and some will also have variable motor speeds. The variable speed settings help to make these tools versatile.

This is because high-speed settings tend to sand surfaces more aggressively than the low-speed ones. As a result, with the variable speed belt sander, you will get more control over your projects.

Another point to note is that some handheld sanders can also be operated upside down, so you can use them in a manner similar to the stationary sanders. However, you should not attempt to use a regular handheld sander upside down due to safety concerns.

How to Buy the Best Belt Sanders

How to Buy a Belt Sander

A belt sander is handy for most types of sanding. But, this is only true if you pick the right model from the many options out there.

While the type is always the first factor to consider when picking one, there are still many other important things to keep in mind.

They include the following:

#1. Power

Sanding might not require a lot of power (at least not as much as other things like sawing) but you still need to make sure that the belt sander that you choose has a motor that is powerful enough.

Belt sanders will come with motors with amperage of as low as 6 amps and others will have as much as 10 amps or more.

Those with more powerful motors tend to be more efficient and also perform better than those with low amperage. However, they will also cost more in most instances. It’s also a good option to get a sander that has adjustable power for different kinds of sanding projects. 

#2. Size

There are different belt sander sizes in the market, so you need to determine what you want. Also, it is important to note that the sizes are according to the size of the sanding belt that they use.

Most belt sanders will fall into one of two sizes: 3 x 21 inches and 4 x 24 inches. The 3 x 21 belt sander seems to be the most popular as their small and compact size makes them easy to handle and ideal for regular woodworking projects.

The 4 x 24-inch belt sanders are great when working on large panels and also when you will find it useful to own a heavy industrial sanding machine.

Choose the smaller (3 x 21-inch) models when you intend to use the machine under various circumstances or when you want something for use at different worksites.

#3. Weight

Weight is always an important factor to consider when buying any handheld power tool. For the belt sanders, it is also an important factor as it determines the ease of use and convenience.

If most of your tasks require you to use the sander at a horizontal position when working on badly misaligned boards, a heavier belt sander will be the better option.

For vertical or overhead sanding when doing some home improvement projects, the lighter the belt sander, the better, as it is easier to handle. For vertical surfaces, a portable belt sander is a better option because you’ll have to physically carry its weight. This isn’t an issue with horizontal surfaces.

Another feature you can get when working with vertical surfaces or tight spaces is to get an adjustable handle. This innovative design will let you sand difficult surfaces without causing too much fatigue.

You can get a belt sander that is as light as five pounds while some will be more than 15 pounds. In short, what you pick will depend on how you intend to use the sander.

#4. Speed

When it comes to the speed you will have to pick between single and variable speed sanders. Single-speed belt sanders are the oldest type; the fact that you cannot change the speed limits their use.

Variable-speed models, on the other hand, make it possible to adjust the speed depending on the project. For most models, the speed ranges between 500 and 1,500 feet per minute. The faster the speed of the motor, the more material it’ll sand off. 

While it might seem obvious to use a high speed sander for more effective and smoother sanding, sometimes you have to ensure that only a small amount of material is removed from the surface to keep dimensions accurate. In such cases, using the motor at a lower speed is the best thing to do.

Some belt sander models only have two speed settings (high and low) while others have a dial that lets you choose any speed in between. The variable speed sanders are great for use with a variety of materials.

#5. Dust Collection

A belt sander produces lots of dust, which can leave you with a lot of cleaning to do afterward. It is vital to make sure that you pick a belt sander with an efficient dust collection system.

An onboard dust canister or bag is always a great addition, but make sure that it is large enough so that you do not have to keep emptying it while you’re in the middle of a sanding job.

Some models also have a dust port or allow you to remove the dust bag/canister and connect your shop vac. These models are the best when it comes to dust collection, even more so if you plan to use your belt sander often.

The benefit of using a belt sander with an attached dust bag is that you can keep your workspace cleaner. Sanding causes a lot of wooden dust to get into the air, and this not only causes your workshop to get dusty, but could also be harmful to your health long term.

The vacuum feature along with these dust bags ensures that all the dust is collected efficiently to be disposed off. Keep in mind that if you don’t use a sander with a dust bag feature, it’s recommended to wear a dust mask so that the sanded particles don’t enter your lungs.


Sanding is always a part of most woodworking projects, and this is regardless of whether you are making furniture or doing simple improvements or large-scale home renovations.

The belt sander is one of the most reliable sanders as it is not only versatile but also easier to use than many other types. However, to get the best service from this piece of equipment, you have to pick the best from the many options on the market.

Picking the best belt sander model requires you to consider things such as the belt size, motor power, weight, and speed. You also have the option to go with orbital sanders that provide a smoother finish because of the type of movement involved.

By considering these points and with our reviews above to help you with your selection, you should have an easy time finding a great belt sander to add to your toolkit.
