Doesn't work so well in a ceiling though.



I have been installing an Engineered Hardwood floor in my basement. I put down some of the dimpled drywrap and covered it with OSB that I wanted to tapcon down so it didn't squeak.

I had the same thought as you in I have drilled holes into the concrete floor before with my regular drill and it did work most times. Often though the tapcon would pull out or just not grip. So this time I went out and bought a Ridgid hammer drill (as I have a bunch of ridgid cordless tools and I could buy just the hammer drill by itself without the battery and charger for about $120)

WOW. I could drill a hole in about 5 seconds, not 1 minute+ like before with a regular drill. Every hole I have drilled has worked with ZERO tapcon popout or screws that didn't grip. Right tool for the job and things suddenly became very easy.
