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?

The drill bit looks okay.

The drill bit looks fine. Just order a HILTI SDS-plus TE-CX with a 6mm (1/4 inch) diameter, along with the appropriate anchors. That is more than sufficient for standard lamps. If you want to hang a chandelier, use a correspondingly larger size.

The drill bit then has 4 cutting edges. Te-CX is important. SDS is, of course, the chuck type.
It costs 7.50 Euro. There are Hilti or Würth stores, or good tool suppliers. You can find these in every larger town.

If you want to hang a chandelier, choose a larger size accordingly. I’ve rarely read something this wrong. This would be fine for a rotary hammer, but here a hammer drill is being used, so the SDS drill bit does not fit. These drill bits are designed to break up the material primarily by chiseling, which requires the bit to move within the grooves—a motion that a hammer drill does not provide. Regular drill bits without SDS work with cutting edges and use light hammering during hammer drilling. SDS bits are not intended for hammer drills; only amateurs with no real knowledge do that.
