I have bought a house built in 1960, brick on the outside and according to the prospectus, lightweight concrete in the walls. I'm wondering which drill and plug I should use... I've googled and asked AI and found out that a special type of drill and machine without hammer drill is required (?). But finding these drills at Honbach, Jula, Biltema, or Clas Ohlson is more difficult... none (?) are labeled as drill for lightweight concrete, instead, it's always "concrete drill," "hammer drill," "stone drill," etc... Found a link on Bygghemma, is it correct?
Thanks in advance for any tips!!! Hope this is the right forum section?

Lightweight concrete is quite easy to drill into, a regular concrete drill bit usually works fine, just make sure it is not an SDS drill bit (unless you have such a machine). I think the product in the link works fine, but you can also find a suitable drill bit at any hardware store, biltema, jula, or clas Ohlson.
In lightweight concrete, I usually use a concrete drill and machine, but turn off the hammering, so it only rotates. With hammering, there's a risk that the 8mm drill makes almost 12mm holes.
So using a regular concrete drill but without the hammer function should work fine? That sounds good then.
I read somewhere that a more precise cut is required for lättbetong... Copilot suggested a "multicut drill" from Alpen (specifically asked which from Alpen worked since Hornbach seems to have many Alpen drills...) but I'm a bit suspicious of multi-purpose tools that are supposed to handle many different things, it feels better to have specific ones. I'd rather ask here and google/check with AI than inside Hornbach as it feels like a pure gamble to get good answers there...

+1 on that. Every hanging hook and shelf out in the garage is secured with 130mm lightweight concrete screws without the slightest worry that it will give way. Just low speed and a lot of torque when they're going in.Matti_75 said:
Feel free to use screws directly! I'm just not very familiar with it, having lived in wooden houses with regular drywall and wood studs before, so I don't really have any knowledge about this. Which screws would you recommend, for example, to mount a TV on the wall? Right now it's for a swivel arm, so somewhat higher load (but a smaller and lighter TV), and it won't be extended far either.
