I bought a chandelier, unfortunately it is not mounted on a hook, but on a plate that needs to be screwed to the ceiling, it was a bit of a problem for me because I drilled one hole and the other was impossible. Moving away a bit from the specificity of this problem, I think my drill is too weak, because I can never drill a hole as deep as it would be useful, I hung a picture once and finally cut a pin a bit, because it was impossible to drill further. I managed to drill one hole in the ceiling to a depth of 3/4 of the length of the pin I have, and when I tried the second hole, I drilled maybe 2mm and the drill was spinning in place, I thought that maybe there was a pipe in this place, so I filled this little hole and tried in a completely different place, but unfortunately also the same, I do not understand how I drilled in one place and not the other ... I borrowed from a friend a device that detects metal under the wall, but it does not work with the service, it beeps all the time wherever I keep it. what do you think? is it possible that there was something underneath it a millimeter from the ceiling?
