DeWalt DCD791 vs. DeWalt DCD708 Compared

DeWalt has always produced a fine line-up of tools and their cordless drill series is no different. If you’re on a hunt for efficient drills, you’ll find quite a lot of worthy options at DeWalt. But for now, we’ll be doing a comparison between the DCD791 and DCD708 which are two of the most epic options from their series. 

Both of them have slightly different specs, so we’ll have to see how that affects the performance of each. Let’s get started so you can find the one that’s more suitable for your use!

Motor Type 

Both DeWalt DCD791 and DCD708 are equipped with a brushless motor system so there is not really any difference between the two, in this regard. 

Since both of them feature a brushless motor, you can expect a terrific performance from these drills. A brushless motor boasts more than the usual firepower you find in brushed motors. They are energy efficient and hence, offer a better performance. 

In addition to the increased efficiency of the motor, you also get longer run times. According to DeWalt, their brushless motors are capable of delivering 57% more power than the brushed ones. 

The cherry on top is the fact that brushless motors are less prone to mechanical wear and tear primarily because there’s no friction that is otherwise found between the moving brushes of the motors. 

So a solid 10/10 for both DCD791 and DCD708 in terms of their motor system which is incredibly efficient and powerful. 


The DeWalt DCD791 cordless drill is superior to the DCD708 in terms of speed. You’ll find a maximum 2000RPM in the DCD791 whereas, the DCD708 maxes at 1650RPM.

The DCD791 compact drill offers 2-speed modes that allow you to operate the drill at an adequate intensity. The speed level 1 gives a maximum power from 0 to 550 RPM. On the other hand, speed level 2 gets you to 2000RPM which is the highest operating speed of the drill. 

The DCD791 operates at a 2000RPM with a 619.55 inches/pound torque capacity that makes it suitable for light to medium-heavy tasks. It can easily pierce through solid hardwood or even metal sheets, for that matter. 

As for the DCD708, you can operate it at two different speed levels just like the DCD791. However, it differs in terms of speed. Level 1 powers the drill from 0 to 450RPM and level 2 will get the drill speed up to 1650RPM

This drill delivers a hard torque of up to 575 inches/pound. The speed and torque capacity of the DCD708 is slightly less than that of the DCD791 yet it is good enough to handle light to medium-duty tasks.


The DCD791 is slightly bigger in size than the DCD708, however, we found the difference to be almost negligible. The former one is 6.9” in length whereas, the latter measures 6.3” in length. 

Since the difference is even less than an inch, we consider both these drills equally easy to manage. They can fit into tight and compact places which makes these tools excellent in terms of maneuverability. 

You can work around all those hard-to-reach spaces with the compact and ergonomic construction of these cordless drills. 


The DCD708 outshines the DCD791 in terms of weight as it is incredibly lightweight at 2.4lbs only. The DCD791, on the contrary, weighs 1 pound more than the DCD708 at 3.4lbs. 

Despite the 1 pound difference in weight, both of them are easy to handle. Of course, the 708 being lighter will be easier to use during long work sessions. But the DCD791 ain’t a lot heavy either. 

Considering the additional power we get with the DCD791, we can really make our peace with that extra pound.

Overall, both of them boast an ergonomic construction which makes them a great fit for professional tasks too!

Chuck Size

Both DCD791 and DCD708 feature a ½ inch ratcheting chuck which means there’s no noticeable difference between the two, in this regard. 

Both these cordless drills by DeWalt boast a metal ratcheting chuck. The metal construction means you’ll be getting your hands on some sturdy stuff. The plastic chucks wear out faster and do not last as long as the metallic chucks and that easily makes both these drills a better option than many others in the market. 

Additionally, the drills support easy and swift changing of drill bits because the chuck is keyless. Overall, the grip of the chucks in both DCD791 and DCD708 is quite decent. However, at times, keep yourself ready for some nuisance since the DCD791 does not always offer a precise grip and requires readjustments.


The price difference between the DCD791 and DCD708 is minimal. The cost of different models in the series may vary depending on the items that are included in the package.

For a bare tool, the DCD791 will cost you around $108 whereas, the DCD708 costs around $94 only. The price difference is barely there especially if you consider the additional 450RPM speed of the DCD791. 

Similarly, if you’re rooting for a kit that includes 2 batteries, a charger, a belt hook, and a kit box along with the DCD791 drill, it’ll cost you around $196. Likewise, the DCD708 with a similar kit fetches a price of $150. 


Since both these drills are cordless, they are powered by batteries. Both of them have the capacity to operate with 20V Li-ion batteries. 

The battery life for both DCD791 and DCD708 is pretty impressive. They can easily serve you well for power-hungry tasks, however, that also depends hugely on the Amp-hour of the battery. 

So in case you’re going to be drilling for long hours, you’ll need to get batteries with a higher Amp-hour rating because the included 1.5Ah batteries won’t be able to handle much.

Final Verdict 

Both DeWalt DCD791 and DCD708 are terrific performers. They are promising choices for light to medium-heavy tasks. In fact, the DCD791 is suitable for heavy-duty professional tasks to some extent as well. 

Both of them are equipped with brushless motors instead of the old-school brushed motors. They deliver exactly what’s promised and even more, to be fair. The construction, design, and build quality are outstanding. In short, both of them are excellent choices but if you’re looking for a more powerful option then, go for the DCD791!
