Drill into concrete wall full of rebar?

There are also concrete scanners available for rent to locate the reinforcement.

I rented a multi-scanner and it registered metal everywhere. It was red and yellow every other cm, never green. The rest of the walls in the apartment aren't like that, so I don't understand why they chose to reinforce so brutally right there.

No multiscanner, a real concrete scanner that shows the reinforcement.

Could it be that you have the electrical panel on that wall and therefore lots of electrical wires laid there?
A classic case with hat racks - oops, drilled through the main line.

Is it one of these: https://www.hyresmaskiner.com/produkt/betongscanner-borrning/ ? Because it looks the same as the one I used.

It's not that you have the electrical panel on that wall with lots of electrical wires laid there? A classic with coat racks - oops, drilled through the main line.

No, we won't be having that kind of fun. The electrical panel is in a cabinet in a closet in the bedroom. (Strange and impractical placement, I know.) I also searched for electrical wires with the multi-detector in the hallway and there were none in the particular wall I want to drill into.

Seems very strange that there seems to be reinforcement everywhere. Have you tried drilling/scanning the entire width of the wall and still hit reinforcement or the scanner goes off, or have you only tried vertically? In that case, it's not reinforcement but must be something else. If it were electrical conduits, you would drill through them directly because they are plastic.

Is it only in the corner that you hit metal? In that case, it might be a prefab concrete frame and there's a weld plate right there. However, it shouldn't go from floor to ceiling.

How deep holes have you managed to make? Maybe it would work to put up the shelf using threaded rods and anchor adhesive otherwise.

Finally, it worked! Managed to get hold of Hilti drill bits and after a lot of struggling, I got through. I was completely sweaty and had to take a food break, not kidding.

It looked like it was welding plate as Snickarkirre wrote. And after I got through that, I encountered metal again a bit further in, but the hole was already deep enough, luckily.

Since the hole widened at the front, I smeared putty around that end of the plug before inserting it. So now I'll let it dry properly before I mount the actual hat shelf.

Thank you so much for all the help and tips!
