Hello,
My partner and I are going to hang up a 40kg heavy cabinet on a wall made of plaster. Upon closer inspection, we find no depth in the plaster. We have drilled a 5cm hole and it's still just plaster. So we cannot use metal anchors as we intended.
Question: What kind of plugs should we use when the plaster is so thick that hollow wall anchors cannot be used?
Thanks in advance,
Mattias

Fischer has plugs that work as plugs when the material is solid and as expanders when they are placed in holes. I have used them where we have concrete hollow blocks, they work there in any case, I hung kitchen cabinets with those. I don't remember the designation, I bought mine at Bauhaus.
Somewhere there must be a rule 
if the cabinet is wider than 40 cm at least one mounting point should be able to go into the stud which is enough if you use some type of anchor in the others. But after reading the first post again, I think you probably have a lightweight concrete wall, I have never encountered a wall with over 50 mm gypsum. Double gypsum is around half and more than that in a home seems odd. So it should be possible to use anchors for lightweight concrete I think.

Thank you for your responses. We have considered the idea that it might be lightweight concrete, but the wall is so incredibly easy to drill into, and the dust that comes out is almost white in color.
The studs must be difficult to find since many instruments can't detect studs deeper than 15-25mm?

It sounds like some have already mentioned it, undoubtedly, as if you have light concrete in the wall; I've never experienced putting 4-5 layers of plasterboard on a wall (which you would have if it's >50mm thick).
Have you tried multiple holes or just one? I thought it might be incredibly lucky/unlucky that you've managed to drill into an old patched repair, for example?
I would thoroughly examine the wall so I know for sure what type of wall it is, if there are studs to aim for, etc., as 40kg is still some weight.

Lightweight concrete is available in most colors (blue, white, black, gray, etc.).
White or light gray lightweight concrete is very common.
Feel the drill dust between your fingers. Lightweight concrete is significantly harder and "sharper" than gypsum board.

Studs are placed c/c 60, so from any corner you should have a stud 60 cm out, etc., but as I said, I don’t think you have studs but rather lightweight concrete. We have Siporex in our house; you can almost push a nail in by hand. Some of our kitchen cabinets are mounted in such material with the same plugs I mentioned earlier without any problems. A tip is to drill the hole for the plug with a drill bit that is 1 mm smaller than recommended so the plug makes contact with the surrounding material. It’s better to have to hammer it in than for the plug to spin with the screw.
