The Best Bosch Belt Sander: Our Picks

Guide: Questions you should ask yourself before buying a Bosch belt sander

Before buying a Bosch belt sander, you should acquire some background information. We have summarised this information in the following paragraphs.

What distinguishes Bosch belt sanders from other manufacturers?

The Bosch company has existed for more than 130 years and stands for professional and high-quality tools. Belt sanders, as well as all other Bosch tools, convince with their durability and good handling, which makes them very popular for hobbyists as well as professionals.

The broad portfolio of products and brands offers optimal solutions. Basically, you will find a large selection of powerful and robust tools at Bosch. The belt sanders in particular are suitable for comfortable sanding with high removal rates on large surfaces. Thanks to the perfect manoeuvrability and thus easy guidance of the tools, they are just as suitable for inexperienced hobbyists as for professional craftsmen.

Did you know that Bosch divides its products into the categories "green" and "blue"?

"Green" stands for tools that are more suitable for home use. Tools in the "blue" category, on the other hand, are particularly suitable for professional use.

Are spare parts and accessories available for Bosch belt grinders?

Bosch offers a very extensive range of products. If you are looking for spare parts or accessories to expand your (home) workshop, you will certainly find what you are looking for at Bosch. The right parts are available in the official shop of the manufacturer as well as in every DIY shop. This covers both maintenance and performance expansion.

Below we have compiled an overview of suitable spare parts for Bosch belt grinders.

Spare part Description
Toothed belt If the toothed belt of your belt grinder is worn out after a long time and tears, you can replace it with a new one. This will keep the tool running like new and allow it to continue to do its job.
Graphite plate The plate is screwed directly onto the rectangle between the two rollers and reduces the friction between the machine and the sanding belt. This makes it suitable for soft sanding.
Sanding belts The more you sand, the faster the sanding belts wear out. When buying a new belt, you can choose between coarse and fine grit.

Bosch not only offers spare parts, but also a wide range of accessories for their belt sanders. These include, among others:

  • Dust bag: The dust bag keeps the workplace clean and prevents the inhalation of sanding dust. It is not just attached, but screwed on, which means it holds tight even during difficult tasks. It makes sense to use a dust bag especially if you use the belt sander regularly.
  • Parallel & angle fence: A fence enables parallel grinding and grinding at a fixed angle. If you want to produce several identical workpieces, you need a rip fence. If edges are to be sanded diagonally, an angle stop is ideal.
  • Holder: The mobile belt grinders from Bosch can also be used as stationary bench belt grinders with the help of a holder.
  • Sandingframe: A sanding frame prevents the belt sander from being tilted, which would result in deep grooves in the workpiece. It is ideal for surface sanding and protects the surface.
Did you know that Bosch offers a variety of apps?

For example, there is an app that allows you to easily reorder spare parts. Another app offers support in the event of service and maintenance.

With these and many other individual parts, you can not only maintain your belt grinder, but also expand it in a very user-friendly way. This makes working with the belt grinder a comfortable experience.

What alternatives are there to Bosch belt sanders?

A belt sander is particularly suitable for high material removal. Therefore, the belts have a coarse grit and the sanding pattern is correspondingly coarse. However, if you want a finer finish, Bosch offers the following alternatives:

  • Orbital sander: The orbital sander is particularly suitable for sanding flat surfaces and sanding along edges. It is used for sanding wood, wood-based materials and painted surfaces. Due to its oscillating motion, it has a lower removal rate than the belt sander.
  • Random orbital sander: The random orbital sander has a round sanding disc and a greater material removal rate than the orbital sander. It is particularly suitable if the sanding pattern is to be very good, as the circular movements ensure that the pattern on the surface virtually disappears.

Decision: What types of Bosch belt grinders are there and which is the right one for you?

The blue belt sanders from Bosch impress with their powerful performance and high robustness. The high material abrasion ensures fast work. In addition, the tools in this category are low-noise and low-vibration, which makes professional work easier. So if you want to buy a tool that will accompany you for many years and where you can benefit from the high quality, this variant is particularly suitable for you.

Advantages
  • Good handling and guidance
  • Robust
  • Low noise

Buying criteria: You can use these factors to compare and evaluate Bosch belt grinders

Bosch belt sanders are available in a wide variety of designs. The individual product variants can be distinguished according to the following criteria:

In the following paragraphs, we explain what the individual criteria are.

Power

The motor power of a belt sander is an important aspect in the purchase decision. Normally, the power of a belt sander is given in watts. Depending on how powerful the drive is, the belt sander will manage more metres. If the sander has more power, thicker sandpaper can be used and more material can be removed with a coarser grit.

Bosch belt sanders generally have a power rating of 710 to 750 watts. This makes them ideal for home use. However, the wattage only gives an indication of the actual power of the grinder. The belt speed also plays a role. This means that despite the medium wattage, Bosch belt grinders are not only ideal for home use, but also for longer professional use.

The wattage only indicates how much power the device consumes per hour. Although you can deduce the power from this, the value can also be deceptive. Therefore, you should also pay attention to the belt speed.

In the following we have compiled an overview of the power required for the use of a belt sander.

Use Required wattage
Home use 700 - 900 watts
On soft materials only 300 - 400 watts
Regular, long use at least 900 watts

Belt speed

The belt speed indicates how fast the sanding belt moves. The higher the belt speed, the higher the removal rate. Bosch belt sanders usually have a speed control. The belt speed of the belt grinders is between 200 and 350 m per minute, depending on requirements.

The speed regulation allows the speed to be adjusted to the corresponding material and the size of the surface. A high belt speed is very practical because it allows larger surfaces to be sanded with less effort and in less time. A low speed, on the other hand, is more suitable for fine work.

Sanding surface and belt dimensions

When working with a belt sander, the sanding surface is an important aspect. This indicates the area that can be sanded with the help of the device. The larger the sanding surface, the faster the surface can be sanded.

The Bosch belt sanders are all equipped with a 76 x 165 mm sanding surface. This corresponds to a surface that is just as suitable for professional use on large sanding surfaces as it is for home use on smaller sanding surfaces.

Below we have compiled an overview of the areas of application and the recommended sanding surface.

Use sanding surface
Professional use 100 mm x 200 mm
Do-it-yourselfer 75 mm x 130 mm
Fine work, such as model making 10 mm x 110 mm

In addition, belt sanders also have different belt dimensions. When buying sandpaper belts, it is important to know the correct belt dimensions.

Weight

The belt sander is usually operated with the hands. For this reason, the weight plays a major role. Bosch belt sanders weigh 3.4 to 3.5 kg, which is a weight that is well suited to all surfaces and types of application. This means that the device is not too heavy even when working for a long time and is therefore suitable for continuous use.

Depending on what you want to sand, the weight is very important. If you want to sand a horizontal surface, a heavy tool will generate more pressure and thus remove more material. For vertical surfaces, such as a door frame, a lighter weight is advantageous.

You can't really go wrong with a Bosch belt sander that weighs around 3.5 kg. This weight is suitable for all surfaces.

Facts worth knowing about Bosch belt grinders

Now that you have gathered enough information about Bosch belt grinders, we would like to give you some additional information. If you already own a Bosch belt sander, you may find valuable tips here.

How long can a sanding belt be used?

Generally speaking, the service life of a belt sander depends primarily on how much it is used. The more you sand, the sooner the sanding belt wears out and needs to be replaced.

When sanding, the sandpaper quickly becomes clogged with wood dust. However, the life of the paper can be extended if you clean the sanding belt to remove the sanding dust and abrasion. Special sanding belt cleaner is suitable for this purpose. These are cleaning sticks made of natural rubber. These are held against the running belt and thus remove the dust.

Can I also use the belt sander stationary?

For many applications, a stationary belt sander is better suited than a mobile one. However, since January 2019, it has been prohibited by law to use a belt sander in a stationary position. Therefore, current devices are no longer equipped with the corresponding holes and threads.

If you still want to use your mobile belt sander as a stationary device, you should first make sure that the holes on the top of your device are available. If so, there is an extra holder for this use. These are an ideal addition for attaching the belt sander to a table.

What guarantee do I get from Bosch on my belt sander?

Despite the high quality of Bosch belt grinders, they can still become defective even with proper use and regular maintenance. In this case, Bosch offers a 12 to 36-month warranty.

Be sure to keep the proof of purchase so that a quick settlement can be made in the event of a warranty claim.

Bosch will repair the defects free of charge. The warranty period is 12 months for professional use and 24 months for private use. For tools purchased after 01.01.2017, the warranty period is even extended to 36 months, provided you register the tools within 4 weeks of the purchase date.

What other products does Bosch offer?

The Bosch company has been on the market for over 130 years and has been able to greatly expand its product range during this time. Among other things, it offers tools, accessories and work clothing for a wide range of trades. Bosch manufactures products for the following trades:

  • Building trade
