Which drill for the ceiling to hang lamps?

Ok, I will borrow a rotary hammer from the hardware store tomorrow and do it with that. In the garage I also found this old thing. It is most likely not a rotary hammer and also not helpful for our problem. I just wanted to upload it here anyway to be absolutely sure.

Can and should a steel bar even be drilled through, or should we try to find a spot where it can be drilled well with the masonry drill bit?

First of all, a proper hammer drill should be used

That is most likely not a rotary hammer

No matter what it is. With that power consumption, it definitely won't work.

Something like that belongs in the household if you need to occasionally deploy "heavier artillery" - drilling, chiseling, etc.

All right, thanks for the info. I will report tomorrow whether the lamps are hung :)

At the discount store L..l in the online shop, there are rotary hammers between 50 and 70€, perfectly sufficient for home use from 5-10mm. Something like this or a brand should be present in every household

So, now I'm also going to give my unqualified two cents here in the expert round.

I don't even know how you can discuss 4 pages about a hole in a concrete ceiling.

There are both mechanical and pneumatic rotary hammers. I usually work with the pneumatic rotary hammer with SDS chuck. Since this one is somewhat more robust and heavier, I don't necessarily use it for overhead work.

Or if I'm too lazy to get it, I sometimes take a simple Bosch hammer drill and clamp the SDS bit into a normal chuck. And yes, that works, even if it can be fiddly. Then I have a light hammer drill where I can control the speed, and working overhead is no problem.

With diameters of 6 - 8 mm, it is also absolutely no problem.

"Can't" doesn't exist, at least not for an East German craftsman. The West German keeps looking for problems where there are none.

Hammer drills, like cheap rotary hammers, always have a mechanical hammer mechanism. For some, a hammer drill is a hammer hammer.

I always find it "impressive" how much time you take to write such long nonsense.
