Looks like my Ryobi 14V drill batteries are giving up the ghost so it's a perfect excuse to upgrade. I'm looking at the Ridgid 18V cordless hammer drill or a Milwaukee Hammer drill/impact combo kit.
Here's the Ridgid $250 http://www.ridgid.com/Tools/R8411503-18V-Hammer-Drill-Kit/EN/index.htm
And here's the Milwaukee $288

So for $38 more I can get an impact wrench and Li-ion batteries. I think that's the way I'm going, but wanted to hear what you guys thought too.
Anybody tried using cordless for drilling into a concrete foundation? Is it an exercise in futility and I should rent a real hammer drill? Also, how do I find out if my foundation is pre-stressed concrete or not?
