What are some of the problems or complaints that you have experienced with Dewalt.

I have several Dewalt tools and thought I was buying the good stuff.
Not the best but good.
Most industrial jobs I have worked used Millwaukee and I know there industrial grade tools are really tuff but I can't afford that grade just yet.
I have two Dewalt 1/2" hammer drills that have developed problems.
The problem with one is that when you hold the chuck and run the drill to chuck the bit before tightening with the key, it just spins. Not tighten. I have to use the key all the way. Like the first and second part of the chuck have seperated.
The other is almost new and never been abused. It wont go in gear. Like it's stuck between hammer and drill. Just grinds.
