I bought the milwaukee set a few years ago when price at big box store went from $499 TO $449. The helpfull salesman told me the price was due to a deal they got. He lied, the price was due to fact that the set included drill/driver, not a hammer drill/driver which I really needed. Hammer drill/driver is necessary for mounting things to masonry/brick work. I bought hammer drill/driver later and have worn it out, head wobbles but it still drills torques and hammers. Recently bought lok-tor
milwaukees latest hammer drill/driver. Batteries change easier now (new design I guess). I use these alot and I am still buying milwaukee replacements.
