Sandpaper (random orbital sander)

The sandpaper for the random orbital sander from WERKSTEIN made a very good impression in the test. The product can be used to sand old furniture, unfinished wood, metal and other materials. The sandpaper is cut in a round shape so that it can be easily attached to the random orbital sander using the attached Velcro fastening system . The sanding paper set consists of several sanding thicknesses and can therefore be used for coarse sanding and also for finer sanding work . The sanding discs have a diameter of 125 mm and are therefore suitable for all standard random orbital sanders.
In addition, there are no unsanded edges or processing defects on the product.

Advantages

✅6 different grain sizes
✅High robustness and resilience
✅Family-run German company

Disadvantages

❌No customer hotline available

The first impression

The packaging and labelling

ℹ️ Here we take a closer look at packaging. Sustainability is becoming an increasingly important factor. In addition, adequate protection of the product must of course also be ensured.

Verpackung des Schleifpapiers
Packaging of the sanding paper

The sanding paper for the random orbital sander from WERKSTEIN arrived for our test in the typical shipping box, so it was easy to open by removing the adhesive strip and was delivered undamaged.
The box contained the stacked sandpaper without the use of a plastic film. An instruction manual is included with the product and is printed on the box, which saves resources. No plastic was used in the packaging, which is also positive for recycling. In this case, the product was fully protected and the sandpaper was therefore in perfect condition.
The packaging of the sandpaper is completely recyclable.
The first impression is very good, as neither the product nor the packaging used was damaged.

After unpacking

Package contents and instructions

ℹ️ Most people’s first impression after unpacking is immediately memorable. Are the contents of the pack complete and does the manufacturer make it as easy as possible for me to use the product straight away?

Weighting: 10%
*The maximum score is 100 points

After unpacking, there were 60 sanding paper discs on the workbench, which were available in 6 different grit sizes (10 per thickness).
Installation and use went without a hitch, as this is very intuitive and works in the same way for the standard sandpaper cuts. Unfortunately, the customer is not provided with a customer hotline as a contact option.
However, customers can contact WERKSTEIN’s customer service team via the e-mail address provided. This information is printed directly on the packaging and on the enclosed business card and can be easily seen by the customer. All in all, this is a very good way to send a product.

This is what our practical test showed

Does the manufacturer keep its advertising promises?

ℹ️ Our practical test is the most relevant and therefore the most important. Here, the product has to undergo a wide range of criteria and tests. We check the functions and product promises of the test article.

*The maximum score is 100 points

We really enjoyed using the sandpaper from WERKSTEIN during the test. Installation is child’s play and can be carried out by anyone thanks to the intuitive Velcro fastening.
In our test, the sanding paper was tested on a standard wooden panel with a normal random orbital sander.
The sanding discs are easy to attach to the machine and guarantee a secure hold thanks to the good Velcro system. Even under heavy loads, the sanding disc runs very smoothly and a good work result is possible for any layman if the sanding disc is used correctly.
The sanding disc is more than suitable for the needs of a DIY enthusiast.
It is particularly important to emphasise that the sanding disc stays firmly in place and runs very smoothly during use.

Price/performance ratio

and ratings from consumers

ℹ️ Finally, we look at how the product compares to the competition. Can it keep up with the competition in terms of price and quality? Would we generally recommend buying it? We also analyse consumer reviews and check whether the critical and positive reviews are actually justified.

CriterionRemarkScore achieved*
Price / performance ratioGood price-performance ratio85 points
Rating cut4.6 out of 5.0 stars on Amazon80 points
Total83 points
Weighting: 20%
*The maximum score is 100 points

On the Amazon platform, consumers have given the product an average rating of 4.6 stars. One criticism is that some of the sanding paper discs do not adhere completely to the random orbital sander. Many customers like the fact that the materials used are of high quality and that sanding is easy. In our practical test, we were also able to confirm these points, but we think the grip is more than adequate and the quality is excellent in our opinion.

Prices of up to €28.38 are charged on the Internet for equivalent products. Very inexpensive products are available for as little as €8.90. The sanding paper for the random orbital sander from WERKSTEIN is therefore in the mid-price segment in our test with a price of €16.97. The price ratio is good for the quality and scope of performance you get.
