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 sander which are the handheld and stationary belt sanders. Each has some pros and cons and will be suitable for different situations.

#1. Stationary Belt Sander

As their name suggests, the stationary belt sanders will be designed to remain in one place and 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 and it will in most cases be larger and heavier than the handheld ones.

Some stationary sanders can also be mounted on a workbench and they are the type that woodworkers will refer to as the 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 will come in various sizes and shapes and 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 on the machine.

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

Also, 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. And this is because high-speed settings tend to sand surfaces more aggressively than the low-speed ones.

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 and so you can use them in a similar manner as the stationary sanders. However, you should not attempt to use a regular handheld sander upside down due to safety concerns.

How to Buy a Belt Sander

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. And they include the following.


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 amp and other will have as much as 10 amp 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.


There are different belt sander sizes in the market and 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 two sizes which are 3 x 21 inches and 4 x 24 inches. The 3 x 21 belt sander seem 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 panelsand also when you want 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.


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, the lighter the belt sander the better as it is easier to handle.

You can get a belt sander that is as light as 5 lbs and some will be more than 15 lbs. And so what you pick will depend on how you intend to use the sander.


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 and 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. And for most models, the speed ranges between 500 and 1,500 feet per minute.

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

Dust Collection

A belt sander produces lots of dust and so it 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 also make sure that it is large enough so that you do not have to keep emptying it.

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, and this is more so if you use your belt sander often.


Sanding is always a part of most woodworking projects, and this is regardless of whether you are making furniture or doing some home improvements or 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 it, you have to pick the best from the many options in the market.

Picking the best belt sander model requires you to consider things like the belt size, motor power, weight, and speed.

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