DeWalt should be called Disappointment. They always disappoint me. My current set of medium priced drill bits is Milwaukee. For the money, I've been very pleased with them.
In my opinion, DeWalt is a home owner grade tool that a lot of contractors use when starting out, or for crews that lose, destroy or steel the tools all the time. You can get them everywhere, but when you buy them, you know that you are settling because you need it right now, and driving an hour to where you can get a better quality tool isn't really an option to finishing the job.
