The Best Disc Sander: Our Choices

Buying and evaluation criteria for disc sanders

To find the perfect disc sander for you, you should pay attention to certain criteria before buying, which can be adapted to your personal needs. To make this easier, some of the most important features are listed below:

In order to show you the relevant aspects in detail, we will now go into each of the individual criteria in more detail.


A good motor power is essential for working with a disc sander and varies between 300 W and 800 W on average. Powerful motors are very suitable for detailed work on wood or plastic and ensure fine results.

Often disc sanders also have a low-noise motor, which makes the work easier.

The speed of a disc sander goes hand in hand with the motor power and indicates how many revolutions the sanding disc of the disc sander achieves in one minute. Here, too, it depends on the materials to be processed and the grit of the sandpaper to find the right disc sander with the right speed.

A high speed is very practical, especially for fine work.

Size / diameter

Depending on your requirements, there are disc sanders for small surfaces such as table surfaces or large disc machines for working on more extensive surfaces such as parquet flooring.

The classic, stationary disc sander has a varying diameter of 100 mm - 500 mm and must always be adapted to personal requirements in terms of size.


For a comfortable use of the machine, it is highly recommended to pay attention to stabilising rubber attachments at the feet of the machine so that nothing shifts. Of course, the weight also plays a role, which is why robust disc sanders are definitely more advantageous and more resilient.

In addition, there is also the option of adding a Velcro pad between the sandpaper and the disc of the machine to guarantee a stable attachment.

The support table

Depending on the size of the material to be processed, the size of the support table of the disc sander can be determined. Everything from 20 x 10 cm to 50 x 20 cm is available to ensure that everything fits perfectly on it.

There are also disc sanders with an adjustable and swivelling support table, which can be positioned as required, as well as a supporting scale.

Extraction connection

Since dust flying around is not only very unpleasant for the accuracy of the work, but also for your own well-being, an extraction connection that is already built in is an optimal function!

Most of them have a connection included, so it is worthwhile to do some good research and look out for it.

To make your search for the perfect disc sander a little easier, here is a short summary of the most frequently asked questions, including the answers.

What is a disc sander?

A disc sander is a hand tool and basically consists of a sanding disc, a support table for the material to be sanded and a built-in motor. Often there are additional features such as an extraction connection, a Velcro pad for the sanding disc or a built-in belt sander.

Primarily, a disc sander is used in industrial crafts for sanding, rounding and refining small workpieces or surfaces made of wood or plastic.

What are the different types of disc sander?

The traditional disc sander

The traditional disc sander consists of a sanding disc with a motor and a table. It is used for processing flat surfaces made of wood, plastic or metal.

Disc sanders vary greatly in motor power, diameter, size and additional equipment.

The belt sander

The belt sander has a sanding belt instead of a sanding disc and is used when working on resistant materials. Manufacturers often combine the disc sander with the belt sander. The belt sander is often used for rough pre-sanding of the material and the disc sander for refinement.

Since belt sanders are very popular and widespread, there are also corresponding guides and recommendations on the product.

What does a disc sander cost?

There are also differences in price. Here is a small overview:

Which grit of the sanding disc is best for which material?

The question about the exact sanding material depends on the material you are working with and the final result you want to achieve.

There are various options to choose from:

Coarse grit

For resistant surfaces such as varnish, paint or rust, an abrasive disc with a coarse grit between 6 and 30 is the best choice for removing stubborn substances or for shaping material over a coarse surface.

Medium grit

A disc with a medium grit between 36 and 80 is recommended for rough preparatory work, as a coarse surface is ideal for rounding and shaping wood and plastic.

Fine grit

To add the finishing touches, a fine grit disc of 100 or more is perfect for enhancing the final corners and edges.


In conclusion, the disc sander is a universal and indispensable tool that is perfect for sanding and polishing in the trade. It is highly recommended to combine it with a belt sander to make your work more versatile. If you only need the machine for a few days or are still unsure about buying it, many manufacturers rent out their sanders for fair prices.

Whether you buy it or build it yourself: If you take all the factors and recommendations into account, you are sure to find the perfect disc sander for your personal needs and turn your work into finely honed masterpieces!
