Can ceiling spotlights be installed in a filigree ceiling - drilling?

Ok, thanks for the info. Then 60-80 € for [Dose, Leerrohr und Kabel] is probably not a bargain but also not completely absurd.

Thanks and best regards,

Then have fun drilling. Which core drill do you mean?
This is the best core drill, it cuts without impact (I have drilled over 150 holes in KS), but if you hit the rebar in the ceiling, you won't get any further.



And then to drill overhead with a core drilling machine? Water to cool the core drill does not flow upwards.
In such a construction block, I have read about such an idea, the people cursed while drilling. And the sockets from the factory cost about €50 without wiring.

Through the ceiling and reinforcement? Don't say things like that, people will believe it and later say "I was recommended such nonsense in the construction forum."

Didn't you have the boxes installed by the factory?

No. Just like also through the mounting plates (I don’t know the correct term) of the Filegran corner. I would only have to drill through the approximately 2 cm thick panel at the sockets. Where the sockets sit, there was also a small hole at the bottom center of the socket where you could insert the pilot drill. Effort per hole about 30 seconds.

Filigree ceilings are 5cm thick and are reinforced depending on the structural analysis. You can also encounter 16mm iron inside, and without a core drilling device, you won’t get through.

So for me, the boxes from the factory looked like this: They were therefore already taken into account during the "pre-casting" of the ceiling panels. From below, after sanding, filling, and drilling, it looked like this: Unfortunately, I couldn't find a picture showing the state before sanding and filling.
