Overview
The DCD991B is a powerful 20V Max driver/drill with a modern brushless motor that supplies 820 UWO (unit watts out) for a smoother and faster application speed. Comprising a comfortable handle grip and robust nitro-carburized metal ratcheting chucks, this power drill is robustly-designed to promote durability during application. Moreover, the sealed and coated switches come in handy in dust containment and moisture resistance.
The other thing I loved about this tool is the advanced brushless motor technology that enhances its overall performance and durability. Ideally, this setting offers optimal power, and when combined with it 885 in. lbs. of maximum torque, this is not only a dependable but effective tool for all pro or hobbyist jobs. In my experience, this is an excellent all-around power tool.
Besides, it has an advanced 3-speed (all-metal) transmission that offers varied speed ranges from 450 to 2,000 RPM, ample enough to perform multiple heavy-duty tasks. In addition, I liked its hammer drill function, which, when switched off, allowed me to use the drill for drilling and driving softwoods, plastics, and thin metals.
Finally, this power tool drill features a distinct 60-lumen LED light suitably located at the unit's base, not to mention its 3-setting feature includes the spotlight mode with a 20-minute delay function after the trigger release. With these features, I felt that the DeWalt DCD991 is the ideal power tool for working in tightly enclosed and dimly lit spaces.

Recommendation
These power tools and kits offer optimal performance capacity and power efficiency for DIY and professional jobs. I found that they are well suited to ease drilling tasks and assess their specs, Though I could see that the Dewalt DCD991 substantially outperformed the DCD791 model.
With more power, features, and speed capacity, I could perform more tasks with much ease and precision, although bigger doesn't always speak better! The relatively lighter weight capacity of the latter can allow you to work for a more extended period with fewer operator fatigue episodes.
You'll love that the DCD991 has convenient side handles for easy operation. Alternatively, if you have a relatively tight budget, you can always go for the DCD791, as it will also get the job done.
Good Luck!
