All these power drills use the brushless motor technology except for the DCD771C2. Most professionals prefer tools that use brushless motors because of the longer runtime they provide. Among the four items listed above, the DCD771C2 also has the least UWO rating but can do most home improvement or DIY jobs.

The DCD796D2 is the only one that has a hammer drill feature and is made for tougher jobs. It also is the highest priced among the four, weighing 8.05 pounds, this is also one of Dewalt’s heaviest hammer drills, but this is actually a plus rather than a flaw. Heavy duty jobs need power and weight which would be harder to complete with lightweight and smaller sized drills.
