What I learned about drilling concrete
I was a Union Ironworker in NJ for 16 years. Hilti was my hammer drill of choice, and nothing beat concrete anchor bolts. we would drill and hammer in a 3/4" anchor bolt to mount an I-Beam that held up a building. Hammer them solid, then tighten with an impact.
