tips drilling concrete pls
Asylum:
i agree on the "drop in " anchors. What's good about them is when your done you don't have the anchor sticking out of the slab like conventional ones.
If you chose to go the with regular anchors, the epoxy method works great like Oldbike54 mentioned.
At work, I have used the threaded bolt type ones, but it loses strength every time you unscrew it and reuse.

I have drilled a billion holes in poured concrete so I guess I'm an expert at something ;D Hammer drill or dedicated rock drill motors are rotary percussion. .. Yes drop in steel anchors. Drill the hole to the required depth,blow out the dust,and not into your eyes ;D.Drop in the anchor and set it with one firm blow with a heavy hammer on the anchor setting tool.And you do need a setting tool to match the anchor style...If you can fit in a 1/2 bolt into the frame then use the larger size. Sounds like you should do some practice holes and setting a few anchors.

I have drop in anchors in my garage floor that hold down my tire changer, works great.
Yes on the Hammer drill-go rent one. It'll be worth it. No water needed suck dust with shop vac.
The Delrod and I have done more than our share of this, I gar-on-tee ;D
oldbike54:
One question , will the drop in anchors resist twisting out every time the bolts are removed ? The reason I suggested using water was because of the size of the wholes , helps preserve the bits . All of the above methods will probably work , do what feels comfortable .

Yes, SDS drill. Will drill those holes in less than 5 minutes. Got one in the garage I'm not using. Too bad you're not in San Diego. I'd do it for ya.
