Concrete – Why won’t a rotary hammer drill holes into the concrete condo walls

concrete

I just purchased a condo on the beach, which was built in 1978. Trying to drill through the concrete but to no avail.

For the past 3 days I’ve been running to the big box stores to purchase drill bits for metal & concrete to use with my regular corded drill, but to no avail. So, I’ve done some research. Purchased a corded SDS Bauer Rotary Hammer Drill and a different drill bit just for my SDS drill to use on concrete. Well, once again I can’t penetrate but maybe 1/8”. Very frustrating! What are in my walls? I live in a condo on the beach, 5th floor. We do get hurricanes, just thought I’d mention that in case it mattered in the building materials that were used. It’s my closet that I’m trying to put shelves in, which share the same wall as the living room. I believe it is a load bearing wall. If there’s anyone that could give me some insight, I’d really appreciate it!

I want to thank all of you for your suggestions! I was fortunate enough to run into a contractor that was working on another project in my building. Turns out, that there is no rebar, wiring or plumbing of any sort where I wanted to put up my shelves. My settings on the SDS Hammer Drill were correct. The problem was, that since the drill was new, sometimes they get stuck. So, he kind of hit the drill with the bit attached into the wall, and Voila! Now it works just fine! Now, onto bigger and better projects! Again, thank you to all that responded!
