Belt sander comparison 2018

Purchase advice on the belt sander comparison or test 2018

  • Belt sanders are sanding machines with a band-shaped sandpaper. Like a conveyor belt at the supermarket, only with enormous speed, the grinding belt rotates over rollers. A distinction is made between hand-held devices and stationary grinders.
  • Belt sanders are generally suitable for flat sanding: hand belt sanders are good for sanding planks, and stationary belt sanders are more commonly used on workpieces. For example, rough wooden blocks can be finely ground with a stationary grinder.
  • Depending on the grain size of the abrasive paper, different materials can be processed. The harder the material, the finer the sanding paper must be. Belt sanders are therefore suitable for metal, wood and plastic.

1. Grinding like on the assembly line! But how does it work?

For belt sanders, the sandpaper sits on a cohesive belt on two rollers. One of the rollers is operated by an electric motor (drive roller) and the other roller rotates only for guidance (pulley).

The grinding surface is the area where grinding takes place. Usually this is between the roles. Below the grinding area is a smooth metal surface, therefore, the grinding belt gives little to the grinding.

This has the consequence that a lot of material is removed quickly, faster than with grinders soft ground, Oscillating and eccentric grinders, for example, have a soft base on which the sandpaper rests. A hard sanding surface does not adhere to the object to be sanded and therefore wears off more.

2. Which belt sander types are there?

Belt grinders can be divided into two categories:

  • stationary
  • hand use

2.1. Grinds like a bench: belt sander stationary

Belt sander comparison 2018: belt

On stationary belt sanding machines, fine sanding work is particularly well done. In the foreground you will also see one of the grinding wheels that are often found on stationary equipment.

Belt grinders that are stationary have either a small one undercarriage or one small workbench over which the sanding belt runs. The device remains, as the name implies, stationary and that workpiece must be passed over the sanding belt by hand.

In addition, most table grinders also have one grinding wheel, The rotating disc is attached to the side. There, freshly sawn wooden blocks can be quickly cleared of protruding splinters and then finely sanded on the belt.

A stationary belt sander is especially good if you many workpieces want to work on one after the other. Due to the stationary structure, the workpiece stands out stable and it can comfortably celebrate long grinding sessions there.

Advantages and disadvantages of a stationary belt sander:

  • good for loose workpieces
  • is stable
  • good for long-term use
  • can not be used for large areas
  • hardly mobile

How to build a belt sander yourself

You can see that in the following video. In it is demonstrated without words, as even the electronics of the belt sander is mounted. An ambitious project for every hobby-tinkerer:

2.2. On the move: the hand belt sander

To large areas such as wood floors or sanding wooden pallets, belt sanders that are stationary mounted are less suitable. After all, you can bad a bulky wooden pallet pull evenly over the workbench. It also makes less sense to push the table grinder upside down over the wooden floor. That's why there are hand belt grinders.

The mobile belt sander usually has a smaller one grinding area As a table belt sander, but the hand grinder is pushed over the surface to be ground. However, there are limits here mobility in the form of the cable length, because belt sander with battery does not exist yet.

Advantages and disadvantages of a mobile belt sander:

  • good for large areas
  • also usable as a stationary grinder
  • especially mobile
  • small grinding area
  • moderately stable as a stationary grinder

In this video, you'll see a hand grinder in full action and some helpful tips on grinding:

3. For the right touch: the most important types of sandpaper at a glance


Occasionally, when searching for the right sanding paper, you will also find the abbreviation "MMThis means for sandpaper not millimeters (this is usually written in lower case "mm"), but stands for micro-mesh Micro-mesh is a grit on a very small scale.The grit begins here from 1,500 grains per inch, Micro-mesh sandpaper is so fine that it mostly for polishing is being used. It is universal for all materials available.

Sanding wood with a belt sander is only one option of many. In principle, every sandpaper can be used for all materials such as plastic, metal and stone. However, some achieve abrasives for certain materials better results than others. For the first rough orientation:

  • brown / red sandpaper is good for wood
  • Gray sandpaper is good for metal

Sandpaper, also called emery paper, consists of four layersCarrier, base binder, abrasive grains and capsticks. The first layer, the support material, is the actual band to which the further layers are applied. It either consists of Paper or linen, Abrasives applied to linen tend to last longer than paper and are therefore often used on machine sanders.

The second layer is the adhesivewhich is applied directly to the carrier. For this purpose, a glue or synthetic resin is usually used. On this adhesive is the third layer, the abrasive grains applied. About the abrasive grains comes as a fourth layer, a so-called cap binder, which additionally stabilizes the abrasive grains. These topcoat is usually dyed, so that different sandpaper types can be distinguished.

3.1. Grain for grain

The granulation indicates how roughly the Surface of the sandpaper is procured. On the sandpaper sit many small grains. In the past, flint was used. Today, artificial grains of silicon or aluminum compounds are on paper.

On the different abrasive paper grades are numbers printed. These give the Degree of grain on how many grains per inch stick to the paper. The higher the number, the more grains are applied as abrasive and the finer the grain.

The small differenceThe higher the grade, the finer you can grind.

Here is a list of the most important grain sizes, which are based on the "Fédération Européenne des Fabricants de Produits Abrasifs" (FEPA):

granulationsuitable for

6 - 30

  • the removal of glue and varnish layers
  • the removal of rust

36 - 80

  • roughing rough wood surfaces

100 - 180

  • the fine sanding of coarse wood surfaces
very fine

220 - 1.000

  • the roughening of painted surfaces to apply a new coat
  • metals

3.2. From A to Z

Some sanding papers are also with a letters such as P or F. Is the Letter before the grade of grit, He indicates which manufacturer's standards refer to the number:

  • P = grit for sandpaper according to the Fédération Européenne des Fabricants de Produits Abrasifs (FEPA). This is the standard valid for Europe.
  • K = is an obsolete name for the P standard.
  • F = grit for grindstones after the FEPA.
  • JIS = is the "Japanese Industrial Standard".
  • ANSI = is the American standards institute "American National Standards Institute".

The P-Standards of FEPA apply to abrasive belts. Is the letter, however after the degree of granulation, then the number gives the temper of the abrasive to:

A, B, C, Dextremely soft
E, F, Gvery soft
H, I, J, Ksoft
L, M, N, Omedium
P, Q, R, Shard
T, U, V, Wvery hard
X, Y, Zextremely hard

As a rough rule of thumb helps to the first orientationThe harder the material to be ground, the harder the abrasive should be. For metal and stone there are hard to very hard and for wood soft to medium degrees of grinding. If you are unsure, you can join medium-hard sandpaper start and decide based on the result whether he needs harder or softer. For wood, medium hardness is always a good choice.

3.3. Synthetic or natural abrasive material?

When talking about the material for sandpaper, it's usually about that Material of the abrasive grains spoken. Here you can roughly differentiate between synthetic or naturally produced grains.

Natural abrasives include quartz sand, flint and natural corundum. However, synthetically produced abrasives are harder and more resilient than the natural ones. As a result, they are longer sharp and achieve better sanding results. Our recommendation is therefore: Always choose sandpaper synthetic abrasive grains.

There are synthetic abrasive grains from:

materialparticularitiessuitable for


  • very hard and resistant
  • withstands high heat
  • most commonly used as abrasive
  • soft fabrics like wood
silicon carbide
  • harder than aluminum oxide
  • does not melt so fast
  • releases carbon at high temperatures
  • good for machine grinding
  • soft fabrics like wood
  • Metals without iron content and mineral materials
  • the polished surface of painted surfaces
boron nitride
  • almost as hard and solid as diamond
  • especially resistant to high temperatures
  • Precision grinding of diamonds or extremely hard steel
  • hardest and strongest substance
  • only low heat resistance
  • especially hard materials such as Glass, porcelain, ceramics and carbide

4. The finishing touches when buying belt sanders - you have to know:

While we have selected the best belt sander available online, you may have other ideas of a belt sander test winner. In our purchase advice you will find the most important criteria, which you should consider if you want to select a belt grinder yourself.

4.1. Who is your type: stationary vs. mobile belt sander?

Belt sander comparison 2018: 2018

Some hand belt grinders can also be mounted on the table and can thus be used as a stationary grinder.

Whether the grinder firmly on one table mounted or free portable depends on what purpose you want to use it for. In the chapter about grinder types, we have already mentioned the most important fields of application for the two categories in our Belt Grinder Comparison 2018:

  • Stationary belt sander are good for grinding small workpieces such as wooden blocks
  • Mobile belt sanders are suitable for large surfaces such as door frames or floors

However, some mobile belt sanders are also with screw clamps fixable on a table, So they can also be used as stationary grinder. If you only rarely grind, then a hand belt grinder is the first choice for you: it can be used for both applications. Although this is only in a limited scope, but if the stakes are rare, then that's enough.

However, you know that regularly small objects smooth grinding, then a stationary tool is better. However, if the stationary grinding table occasionally with to travel come, then pay attention to a machine with a small base as a table. It is also worth taking a look at the weight.

If you regularly have a variety of grinding projects, then you should consider whether it makes sense to add both types, If the home workshop gives the place, the table belt sander is always ready and the hand sander is packed ready for transport on the shelf.

4.2. Powerful and fast

The power consumption (watts) provides information about how strong the motor of the belt grinder can be. The more watt, the stronger the motor theoretically. If the engine is too weak, it may cause you to bend your knees, for example, when you press a workpiece heavily onto the sanding belt to sand down a lot. More watts promise accordingly more powerful grinding work.

Belt sander comparison 2018: belt

Grinding is particularly convenient with a speed controller.

In order to fine sanding results to get to, the tape speed is crucial: it is in revolutions per minute (Rpm). Occasionally, idle speed is also used. Here you can see how fast the motor or here the grinding belt can rotate without being pressed onto the belt.

If the new grinder also has one Speed ​​control brings you a belt sander with test-winning qualities in your hands. The speed control regulates the speed of the sanding belt. Too high speeds can the workpiece heat up a lot.

at sensitive materials there is a high chance that high speeds will damage the workpiece. Plastic, for example, would heat up and could deform or melt during belt grinding.

Quality guaranteed: The highest quality you get when watts and tape speed have high values.

4.3. Plenty of area for areas

Belt sander comparison 2018: comparison

The length of the abrasive belt is not equal to the length of the abrasive surface.

The grinding surface is the area on the sanding belt that is effectively sanded. The size of the grinding surface corresponds not equal to the length of the abrasive belt, Since the tape is passed over rollers through the tool, a maximum of half the length of the tape is ready for grinding. In addition, in some cases, the grinding surface of the housing of the tool limited, The size of the grinding surface has different effects on the working methods for the respective belt grinding types.

table grinders can also grind only small workpieces with a small grinding area. The bigger the area here, the better flexible you are in your grinding projects. The longer the sanding belt is, the smoother it can be long strips be sanded.

mobile Hand belt sander Although they are more comfortable to use with a smaller grinding surface, they do tend to work better with a large grinding surface even sanding, This is especially important for large wood panels. If the grinding surface is very small, it becomes very difficult to guide the tool evenly over the work surface and it can Waves in the wood arise.

Since many Handbandschleifer too to small table grinders repurpose just a big grinding area is advantageous here. The abrasive surfaces of mobile grinders tend to be smaller than those of table grinders.

4.4. Fight the dust

Belt sander comparison 2018: belt sander

Some belt sanders have their own dust collector.

The accruing dust When grinding machines, it should not be underestimated. If you work classically by hand with a wooden block and loose emery paper, that will hardly disturb the little bit of dust. But an electric belt grinder replaces considerably more material in a short time.

The dust is harmful to eyes and lungs. He is also so fine that he stubbornly pollutes textiles. To counter this, many tools have one Dust extraction, You can connect either a conventional vacuum cleaner or a special vacuum cleaner to this round opening.

Due to the high speed of the rotating rollers, the belt grinders generate enough electricity to catch some of the dust themselves. But some models have their own receptacle, Especially with hand belt sanders, it releases you from the annoying vacuum cleaner pipe and you save yourself the power consumption two power-hungry devices.

5. Safe grinding - safety tips for belt grinding

Since, as already mentioned, a lot of dust accumulates, you should definitely one Mouth and eye protection carry. In particular, if you sand down painted surfaces, the resulting is there Dust toxic and may even cause allergic reactions.

The security experts from Stiftung Warentest advise to use an integrated dust collector instead Vacuum cleaner in addition to join. They think the better the dust is caught.

A glasses Not only does it protect your eyes from harmful dust, but it also helps you in a cloud of dust by views to keep. Especially when you are working on a table grinder, it can quickly happen that you no longer see how dense you are in the cloud finger lie on the sanding belt. That's why Protective gloves also mandatory.

The sanding belt whizzes past your hands with great force and speed. It's even tough enough to grind metal. It is also strong enough to cause great damage to your hands. Especially when you are working a workpiece on the table grinder, hold the block over the rotating belt with your bare hands.

To go out-of-the-skin: The sanding belt can not only cause burns on the skin, but also over a large area Tear off skin, In addition to the immense pain you also carry great scars. Always work with you gloves!

Like almost every powerful tool, belt sanders also cause noise, Straight grinding is predestined for longer working sessions, but those who are exposed to high volumes for a long time damage their ear canal. Due to the rotating sanding belt, the materials are caused to vibrate, so in addition to the actual noise of the engine even high-frequency noise peaks. If you want to escape a tinnitus, you should also have one when grinding ear protection carry.

6. Grinding like a master

Whether you work with a mobile or stationary belt sander - if you Scored in the material you want to avoid yourself from coarse to fine sandpaper work ahead. Grooves are deep furrows in the material that are created during long sanding with the same type of abrasive paper.

These furrows are indeed on very fine sandpaper, but they are there not to see anymore, The longer you grind with the same paper, the more pronounced the grooves become and more difficult to get invisible. When grinding, start with a small amount of grit and then go gradually higher, If you start with 60s paper, you should then use 100s and then 120s. This should go so far until the desired quality is achieved.

Insert sandpaper correctly: With the sanding belt, you must pay attention to the direction of movement printed on the inside. Put it in the wrong direction on the rollers, after a short while the paper splices open and the sanding belt falls down.

If you grind wood, you have to with the grain go. Especially with soft material offers a coarse grain. The harder the material, the finer the grain. However, this is not an exact science, so here are the expert opinions also repeatedly diverge.

The expert tip: In order to have a precise view of the condition of the workpiece, it is worth the area to be ground to suck off regularly, In addition, stuck dust affects the grinding quality, The problem is also present despite automatic dust extraction and collecting container.

7. Frequently asked questions about belt sander

7.1. What is better: belt sander or orbital sander?

Belt sander comparison 2018: comparison

Hand belt sanders are mainly good for wide areas and are hard to get into corners.

On belt sander not only grinds off surfaces, but because its abrasive belt is strengthened from below with a solid plate, it's particularly good at Straighten bumps, With it can be surfaces and boards evenly smooth and flat. However he is very large and does not fit in cramped corners.

On sander is mostly smaller as a mobile belt sander. With him you come very easy in small cornersif, for example, you sand down wooden planks. However, its small size is also its disadvantage when large areas are to be ground uniformly. A small sanding surface is difficult to handle and can quickly become too uneven waves lead in the wood.

Random Orbit Sander Although not quite as big as a belt sander, but have a slightly larger grinding range than the orbital sander. They are therefore a good one mediocre between belt and orbital sander and can optionally be variably used for both purposes. In a grinding machine test, Stiftung Warentest particularly praises Bosch's multi-sander.

7.2. Which belt sander is suitable for knife makers?

Belt sander comparison 2018: belt

You can also grind metal with the right sanding belt. It's usually gray.

In principle every stationary belt sander suitable for grinding knives. You only have to the right sandpaper choose. It should be very fine (at least 200 grit) and the grain size suitable for very hard materials (ie the letters T to Z). Boron nitride or diamond abrasive grains are suitable. Details on choosing the right abrasive paper can be found in our belt sander test above.

7.3. How much does a belt sander cost?

The Price range enough for belt sanders from 40 to 400 euros, The prices are independent of whether it is a stationary or mobile belt sander. If you only want to sand wood with a hand belt sander, a cheap model from the hardware store is enough.

However, if you want to grind other materials, you have to go for many different ones Sandpaper varieties can fall back. Here, however, the problem arises that it is unknown cheap brands mostly little choice on matching sanding belts are. Anyone buying from well-known manufacturers can be sure that a large range of sandpaper grades is available.

Bosch and Makita distribute models in the middle price sector between 100 and 200 euros. These are usually also equipped with a dust extraction and collecting tanks.

7.4. Which manufacturers and brands of belt sanders are there?

Bosch and Makita are not the only prominent toolmakers. Scheppach, Einhell, Black & Decker also bring interesting grinders onto the market.

Here is a small list of other manufacturers:
