Go to http://www.grizzlyindustrial.com/. They have a 3 function rotary hammer/drill that for small DIY jobs can't be beat IMHO. I comes with several drill bits and a couple of chisels. This uses SDS bits and additional ones are quite inexpensive. This tool will break concrete, and is outstanding to drill holes up to 1/2" in concrete. Best news is, it doesn't cost an arm and leg. Grizzly stands behind their tools exceptionally well, too.
