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.
| Criterion | Remark | Points achieved* |
|---|---|---|
| Product protection | Carton is sturdy, product sufficiently protected | 100 points |
| Sustainability Packaging | Unnecessary packaging waste was avoided, items were packed compactly | 97 points |
| Product labelling | Labelling for occupational safety available | 100 points |
| Miscellaneous | High-quality packaging, also suitable as a gift + additional box for storing the drill bit included | 100 points |
| Total | 99 points |
*The maximum score is 100 points
The HOPINGA drill bit arrived in a standard cardboard box . The box was undamaged and easy to open without tools. The box contained the packaging of the diamond drill bit as well as filling material to protect the product during shipping. To protect the product from dust and dirt, the drill bit was also packed in a sturdy plastic box.
The packaging is largely recyclable, but the plastic box and the plastic film protecting the drill adapter and drill bit are not recyclable.
In any case, the packaging makes a good first impression.
After unpacking

*The maximum score is 100 points
After unpacking, there were four things on the workbench. Firstly, the drill bit, the SDS Plus adapter for the drill, a centring drill and a plastic box that can be used for storage.
Information on use and the area of application can be found on the instructions and the product packaging. Contact information can also be found on the box and the instructions. Unfortunately , there is no customer hotline that customers can call if they have any problems.
Overall, the type of product packaging is very positive and very customer-friendly.
The first time in your hand
Product processing and appearance
ℹ️ Before we start the practical test, we take a close look at the product processing. How high quality are the materials used? Is the look and feel satisfactory?
| Criterion | Remark | Points achieved* |
|---|---|---|
| Visual appearance | Very simple, modern design | 100 points |
| Processing | High-quality workmanship of all individual parts | 97 points |

*The maximum score is 100 points
The drill bit is made of a special hardened steel with diamonds in the tip, which are particularly suitable for drilling holes. To insert the core bits into a drill, it is necessary to first screw the SDS Plus adapter firmly into the core bit and then connect it to the drill.
It is particularly important to switch off the impact drilling function (if present), as this could damage the drill bit.
If centring is required when drilling, the centring drill can be used.
The centring drill, SDS Plus adapter and drill bit all make a very high-quality, stable impression.
The manufacturer supplies a plastic box for storage so that you can enjoy using the drill bit for as long as possible.
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.
| Criterion | Remark | Score achieved* |
|---|---|---|
| clean hole | Very clean hole – no residue | 100 points |
| Simple assembly of the drill bit | Very easy to install, no large tools required for installation | 95 points |
| Easy disassembly of the drill bit and accessories | Removal of centre drill very difficult, but removal of drill bit easy | 83 points |
| Easy to use, even by a layperson | Easy and simple operation for laypersons | 95 points |
| Total | 93 points |
*The maximum score is 100 points
We really enjoyed working with the diamond core bit from HOPINGA . It was very easy for a layman to drill a hole and the desired hole was made very cleanly and without any major residue. The effort required depends on the material, of course, but is very manageable.
Fitting to a suitable drill is very simple and doesn’t really require much instruction. Unfortunately, the same cannot be said for disassembly, as this is very difficult and requires a lot of force, especially when removing the centre drill.
Our conclusion from the practical test: easy handling and a very successful result.
