Can't drill a hole deep enough
Hi!
I'm trying to drill a hole through a brick wall, but for some reason it won't go deep enough, I've already broken 2 different drill bits trying.
I'm trying to put up a shelf, and on one side I was able to drill the holes just fine, but on the other side they won't go through deep enough, but I also can't see anything metal or anything in the way. I've tried to space the holes out on this side (by at least 15cm), and still the hole doesn't get deep enough. I've even tried to put some water in the hole, as I've seen people suggesting this helps to cool the drill bit. I'm also keeping the drill straight, and using the same technique I did on the other side.
I'm at a loss for what I'm doing wrong, or what could be causing this. There's no pipes running on this wall, so the only thing that it could be would be metal, but I can't see any metal, and I previously had a mirror in this wall (but way higher and more to the left), and I remember hitting a metal but it was visible, and this time there's nothing.
Any tips on what I should do? If I can't drill a hole, would it be stupid to use those glues on one side only?
Edit: Thank you for all the replies! I was finally able to do it, it's not perfect but it's secure. It took a bit of patience but the biggest advice I could give is don't force the drill (and use the correct drill bit), it should work for you, you don't need to force it, just take small breaks and clean off the dust with a brush in between drilling!
