Hello forum community,
I hope this is the right place; if not, please feel free to move it.
Today, we tried drilling holes on the ground floor to hang some lamps, but we got stuck.
After drilling a short distance, we couldn’t go any further.
We tried several spots in the hallway, and only at one point were we able to drill through.
We suspect there is a steel beam, and the spot where we succeeded was where we didn’t hit the beam.
Attached is a photo of our drill bits. Our assumptions:
- The silver bit is for masonry and concrete
- The bits below are for wood
- Are the top bits suitable for metal, or do we need different ones for that?
Unfortunately, the instructions we found online aren’t very clear.
As a result, we already used the wood drill bit on the ceiling, which wasn’t good for it.
Is it even possible or recommended to drill through a steel beam, or should we try to find a spot where the masonry bit works well?

Is it even possible or advisable to drill through a steel bar, or should we try to find a spot where it’s easier to drill with a masonry bit? First of all, you should have a proper hammer drill.

That is most likely not a rotary hammer. No matter what it is, the power rating definitely isn’t sufficient for this job.
A tool like this belongs in any household where you occasionally need to use “heavy-duty equipment” – drilling, chiseling, etc.
At the discount retailer L..l’s online shop, there are rotary hammer drills priced between 50 and 70€ (approximately $55-$77), which are perfectly sufficient for home use with drill bits from 5 to 10mm (0.2 to 0.4 inches).
Something like this or a branded equivalent should be available in every household.

I don’t understand how you can have a four-page discussion about a hole in a concrete ceiling.
There are both mechanical and pneumatic hammer drills. I usually work with a pneumatic hammer drill with an SDS chuck. Since it is a bit heavier and more robust, I don’t necessarily use it for overhead work.
Or if I’m too lazy to get it, I sometimes use a simple Bosch rotary hammer drill and fit the SDS bit into a regular chuck. And yes, that works, although it can be fiddly. This way, I have a lightweight rotary hammer drill where I can control the speed, and working overhead isn’t a problem.
For diameters of 6–8 mm (0.24–0.31 inches), it’s absolutely no problem.
“Can’t” doesn’t exist, at least for an East German tradesperson. West Germans tend to look for problems where there aren’t any.
Rotary hammer drills and cheap hammer drills both have a mechanical hammering mechanism. What one calls a rotary hammer drill, another calls a hammer drill.
