Hammer drill vs iron / stone

[Screed]

Hello,

Amateurs' night is approaching at my place, and as usual, I'm hitting a snag.

I need to install three brackets for a roller blind.

I drilled a hole as shown in the image in the concrete wall, but damn it, I've hit either an iron beam or a stone because the hammer drill can't go any further.

So the question is, how should I aim to avoid similar problems, horizontally or vertically?

Grateful for answers

How deep did you get before it went bad?
Which drill did you use?

About 25mm before it stopped, 6mm drill,

If you take a nail and push it in and tap gently with the hammer, does it sound metallic then?

Otherwise, I'm a bit curious if you might have accidentally set your hammer drill incorrectly?

Testing with a screw, I can't say if it sounds metallic or if it's just stone.

Not much to set on the machine, it's with or without hammer function and it's SDS. It's hitting something though as it gets very hot.

Switch to a metal drill bit and drill through the reinforcement?

Sounds strange.

I have a Mecc Tools rotary hammer from Jula (cheap junk, I know), but I can drill 18mm holes in natural stone and rock with it. Not quickly, but it works.

However, when a drill bit is about to give up, it can sometimes stop and then just get hot.

So, the next step is to try with another concrete drill bit?

Don't have one but might end up there.

It's probably a rebar you've encountered. I personally drill straight through it with the same drill. If that doesn't work, I drill a new hole next to it. I've never tried the metal drill variant.

What kind of drill do you have? The drill is crucial when you're going through something.

Took a new drill bit but it's the same, gets hot immediately.

No monster machine by any means

You're probably encountering a rebar. I drill right through it with the same bit. If that doesn’t work, I've drilled a new hole next to it. I've never tested the metal drill bit variant.

I might have to try next to it first. What I'm wondering is if it is iron, do they go vertically or horizontally?

Dewalt XLR plus and a Dewalt machine

I guess I'll have to test it next to it first. What I'm wondering now is if it's iron, do they go vertically or horizontally?

Unfortunately for the sake of your curtains, my guess is that any reinforcement must run horizontally there.

 

[Screed]

Unfortunately for your curtains, my guess is that any reinforcement must go horizontally there.

Then maybe one should try to aim a little higher. 2cm should be enough, right?

Agree, that should be enough.

Fingers crossed!
