It is essential to get a good quality finish on the project. For instance, when you are going to paint or varnish, the prep work of the materials is crucial. Otherwise, it doesn’t matter how well you have done the next stage; you will don’t get desiring result. Power is the essential quality of this type of tool except which you must disappoint at that very moment. It is because without the power you can’t give an excellent finish to your work.

Multiple belt Sanders are available in the market. We have shortlisted the best Belt sander models to help you in this case and match your requirements.

We have done significant research on these power tools, and then we have suggested the best five models to you.

What is Belt Sander?

Belt Sander is a power tool. And, it is used to deliver good results in shaping & finishing wood and other materials. The tool comes with an electric motor and sandpaper. The motor turns a pair of drums on which a continuous loop of sandpaper is mounted.

You can move the machine over the material, or you can make it fixed. Users sometimes keep the stationary ones fixed on a workbench, due to which these are known as bench sanders. You may find these combined with disk sanders also.

About it:

Whether the work is to refinish wooden furniture or sand down drywall seams, these Belt sanders can quickly make your job done. The type of machine you are going to rely on is the kind of material you will work with. The device is an ideal solution for those who use it for sanding frequently and for larger projects. The tool needs a steady hand, but you don’t need to worry because you can cut any surface deeply by applying more pressure on the side.

Types of Belt Sanders

These are available in the market as portable and as benchtop models. The first one is a hand-held model. On the contrary, you must bring the necessary workpieces to its sanding surface while using a fixed benchtop machine. However, before choosing the model, users need to decide the type of job they are going to do using the gadget. Whether you feel each of these essential, then buy sanding stands and fences. These can convert the portable models into stationary models.


These are helpful to remove non-ferrous metals like aluminum. Usually, these metals clog grinding wheels, and thus these make them useless for grinding soft metals. The minor grooves in the sandpaper are opened up & going around the arc of the drive wheel and reduce the risk of clogging.

Whether you have an ideal area to fix the machine, then mount it on a tabletop. If there is no space, buy the stands to set the device in place. You can remove the tools easily also.

It is the top horizontal surface of this machine we use. Sometimes, the workpiece has a smaller size compared to the top of the belt. In this case, you have to set a fence over a drum and fix the workpiece in a stationary position. Now, let the belt spin beneath the workpiece.

When you will smoothen the end grain, reposition the machine to make the position of the working surface vertical. Generally, people use belts four inches wide by three feet long, which is the most common size. If you use more extensive tools, then use six-inch by forty-eight-inch belts or more extensive than that.


These machines consist of similar accessories – a belt, two drums, a motor, and a switch. People can carry this type of tool to any place where its extension cord can reach. We use this type of tool on the surface for sanding.

It is ideal for the cabinetmaker’s shop as it helps erase glue lines and make joints flush on facers. It indicates especially the front-facing vertical and horizontal elements which are used to frame doors and drawers. Then, you can complete the final smoothing using a finish sander. As this is a two-handed tool, you have to place your workpiece securely. While you turn on the tool, you must not keep the belt in contact with the work.

As soon as it has reached full speed, you need to take it gently onto the workpiece. Then, you have to first touch down with the rear of the belt. If you cannot erase material from the surface, the tool’s weight will do its job by applying all the force required.

The size of the tool varies like a full 1.2 by 2.5 m. Besides, a few machines come in large sizes as 1.2 by 0.7 meters. When you sand wood, it creates a large amount of sawdust. It is the reason why woodworking comes with some type of dust collection system. The dust system can look like a cloth filter bag or an extensive vacuum system. A filter bag is used in a portable sander, whereas a comprehensive vacuum system absorbs dust particles away into a central collector.

Use the Taut-belt sanders to adjust the angle of the idler drum to keep its position centered. You can use the Slack-belt sanding while producing guitars as well as other medium-sized wooden objects.

Key Features:

Power: Always select the model with more amps because you will get more power when there are more amps. In most cases, these tools come with electric motors having an amperage of 4 to 10 amps.

It is the critical aspect that makes one tool different from others. For example, you can see a 9-amp motor delivering better performance than a 2.5-amp motor. When using the machine on hard surfaces, always choose a high-powered tool for efficiently driving the belt.

Belt size:

These tools are available in various sizes of belts. It depends on the surface area you will cover while using the machine. The standard size of the belt is 3-inch wide (3 x 18-inch or 3 x 21-inch), but if you require, you can use other sizes.

The smallest size of the belt is 3 x 18-inch, and it is the lightest one also. This small tool enables you to use it with one hand. While you will use a belt with a bigger size, such as 4 x 24-inch, you require some arm strength for safely operating. With the help of the larger Sanders, you can sand wide planks of wood which is a significant benefit.

Variable speed:

Always choose such a model that can offer you variable speed settings because of which you can use them for various tasks. A few machines are available with one speed, whereas others have variable speeds. You can use

Single-speed models with limited usage, whereas the variable speed, enables you to manage the speed.

Generally, these tools come with a speed range of 500 to 1,500 feet per minute. A few tools come with two speed settings (high and low), whereas other models come with a button to select different speeds. The larger the surface area on which you will work, the more oversized belt you will need.

Other Considerations:

Dust collection:

The machine usually contains a built-in dust bag used to collect most of the coarser dust. Although we use this, a lot of fine dust still goes into the air. If you are not performing excessive belt sanding, you can get a hose to connect the sander to the shop vacuum.

The hose allows you to use it as this one came with your shop vacuum. It is generally very large or stiff, which is a significant issue. This small-diameter hose is super flexible and designed for dust collection. If you want, you can purchase it from a woodworking store. Usually, the dust ports are available of various sizes like squares, etc., due to which users need to fiddle around to get the hose to fit.


While you are going to purchase the best model, you need to consider this factor. People who are using the tool in a horizontal position should buy a heavier tool. Besides, those who want to use it overhead and vertical sanding have to purchase a lighter one. A few models are available at low weights like 5 pounds, whereas a few have more than 15 pounds. You should have a plan before settling on one.


$40-$100: You won’t get models with plenty of horsepowers within this price range. Most of these models are not perfect for heavy-duty sanding; instead, you can use them for home workshops.

$100 and up: Tools in this price come with tilting belts and cast iron bases. These feature a compact design that offers enhanced portability along with auto-tracking belt systems.

  • The tool is perfect when you want to remove paint or any unwanted residue from a surface. Thus, it makes the surface smooth by clearing residue.
  • You can use a hand-held belt sander for polishing metals such as brass and aluminum. However, for delivering a super finish to the workpiece, take the help of fine-grit sandpaper.
  • You can use the tool for finishing touch to wood, metal, and flooring. These are useful for those tasks which are time-consuming, like smoothing corners and removing burrs. People use the machine for cleaning stains from wood, paint from surfaces, and resurfacing old furniture.
  • These tools perform superbly for leveling and smoothing rough boards. Users only have to begin at an angle to the grain and then end with it. You can start using 80-grit, and then you can turn it into 120-grit.

The process to Choose the Best one:

The ideal width of the belt for multi-purposes using is 3-inch. You can see the tools designed for wider and narrower belts.

There are different sizes of tools that use different belt sizes. For example, the smaller ones have 3 x 18-in. belts, midsize tools have 3 x 21-in. belts, and larger ones have 3 x 24-in. belts. You can use the smaller ones easily for shaping and scribing. For casual use and minor works, these are perfect.

On the flip side, you need to use the larger ones for more extensive work and shop. However, it is recommended to use the 3 x 21-in. machines. A few models that come with 2-1/2-in.-wide belts are perfect for one-handed use, whereas devices having 4-in.-wide belts are used by cabinetmakers.

People who want to use disposable, and longer-lasting, dark brown premium belts, can use Aluminum oxide. This traditional grit material is available in a less expensive khaki-color form. Multiple users want to use zirconia belts for 80 grits and coarser. These are known as “planer” belts also. You can get them available in bright blue or purple color. These belts come with sharper, more rigid cutting particles. The  Zirconia belts are a little bit more expensive compared to the premium aluminum oxide belts.

How to Use Belt Sander:

You must not push it down; allow it to do its work gently. Just move gradually, then overlap passes and let the machine go past the end without dipping. You have to make sure that you are not tipping the sander or changing speed or direction. It is better to keep the cable on the shoulder.

Watch Out for Gouging: If you want to stop gouges, take the help of new belts. Make sure that you are not using grits more acceptable than 120, and you have to keep the plate clean under the belt.

Safety tips:

These are safe enough to use, but still, it is better to take precautions.

  • You must not breathe dust as it is unpleasant for us. For protecting yourself, you need to wear a dust mask when you sand. If you want, you can rig up a shop vacuum to collect dust.
  • You have to unplug the machine when you’re going to change belts or clear dust bags.
  • It is recommended to blow or vacuum the residue before going to use the tool on the metal. Otherwise, when you are going to sand metal, it can generate sparks, due to which it can start a fire while getting mixed with the sawdust in the machine.
  • You have to ensure that you have turned off the trigger before plugging the machine. It comes with a locking button holding the switch.
  • These machines exert force during work, due to which you need to work securely. Otherwise, it can slide away from or right into you.

Watch Out on Plywood:

These are capable of taking off wood, due to which these can wreck plywood instantly. In this case, you can draw a pencil line for sanding solid-wood edging flush with the plywood. It helps to let you know when you need to start removing the veneer.

Belt Sander Maintenance:

You have to ensure that the tool is placed accurately as a few machines prefer a particular direction indicated by an arrow on the inside. However, if you want, you can install a non-directional belt. Hence, you merely have to track it to keep it centered on the roller.

First, your task is to hold it and then turn it on to check whether it rubs against the housing or begins to work. When the trigger is on, you need to adjust the position of the tracking knob till the belt is coming in the center position. While the tool is on the wood, it may require a slight adjustment. Whether the tool comes with automatic tracking, then you do not need to do anything.

Keep the Belt Clean:

You can take the help of a belt-cleaning stick for cleaning the pitch buildup on the belt. Then, your job is to push the rod against the moving belt for cleaning. If you have a large machine, you need to clamp the stick in a vise and sand it.

Suitable for Rough Sharpening:

These are perfect for sharpening rough surfaces of tools such as axes, shovels, knives, and chisels. You can use a zirconia belt, but you have to clean the dust bag by removing dust.

Shop-made stand:

It is a valuable accessory for those who do woodworking too much. The stand holds the tool on its side,

upside down or vertical, allowing the machine to do its work easily. The design of the stand relies on the shape of your tool.
