Motor and Power
First and foremost, note that DeWalt DCD777C2 and DeWalt DCD780C2 use different types of motor. Because of this, they may have different efficiency, battery life, and longevity. The difference may appear insignificant at first, but the effects will come up in the long run. See also: DeWalt DCD771 vs DCD780.

DeWalt DCD777C2 is equipped with a brushless motor, which is great because a brushless motor is more efficient than a brushed motor. The company claims that it has 30% more runtime than brushed-motor models. It doesn’t take as much power to rotate. The lower power consumption allows for a longer battery life. It is also more convenient to use continuously because it doesn’t generate much heat. And since it doesn’t make much friction, it can last for a longer time.

On the other hand, DeWalt DCD780C2 comes with a brushed motor. It is not as efficient as DeWalt DCD777C2’s motor. It relies on the physical contact between the brushes in order to rotate. The physical contact creates friction, which, in turn, causes some resistance and heat. The resistance increases the power needed to rotate the motor, and the heat may cause the unit to overheat if used continuously for a long time.

In terms of total output power, DeWalt DCD777C2 vs DCD780C2 are almost similar. DeWalt DCD777C2 is just a bit lower with a power rating of 340 UWO, whereas DeWalt DCD7780C2 is slightly higher with a power rating of 350 UWO. This time, the difference is not big. Both models are suitable for a wide range of tasks.

Battery
DeWalt DCD777C2 tends to have a longer battery life. This is because of the brushless design of the motor. When drilling continuously, you can get about 25 minutes from a single charge. This is not bad at all. Not to mention that the recharging process only takes approximately half of an hour. So, there won’t be much downtime during a drilling session.

DeWalt DCD780C2 tends to last for about 20 minutes when used continuously. Then again, the battery life is also affected by the speed that you are using. For sure, this is also good. The recharging process usually takes about half of an hour as well.

Both DeWalt DCD777C2 and DeWalt DCD780C2 work with the DeWalt 20V Max rechargeable batteries. Actually, there are several different options for their batteries. The included ones are standard, but you can purchase larger batteries if necessary. If you don’t want to wait for any recharging process during your work, consider getting one or two spare batteries so you will be able to just swap the batteries to continue working when running out of power.

Maximum Speed
The next difference between DeWalt DCD777C2 vs DCD780C2 is the maximum speed. Each of these two models has a two-speed transmission, so you can choose the suitable gear for drilling delicate and tough materials. Actually, the difference is not really significant, but it is still a difference nonetheless.

With DeWalt DCD777C2, the first gear goes up to 600 RPM and the second gear goes up to 1,750 RPM. Even with these speeds, this model is already capable of tackling most house projects. It is great for both light and heavy-duty tasks.

With DeWalt DCD780C2, the first gear also goes up to 600 RPM, but the second gear goes up to 2,000 RPM. It can reach slightly higher speeds. Indeed, this model has been designed specifically towards professional craftsmen who need a compact yet powerful drill. The slightly higher speeds may help you finish tasks a bit more quickly. But the difference is not that much.

Design
In general, both of these two models are compact and lightweight. With either model, you will be able to navigate and aim your drill easily, even when working in a tight space. Both models are also well-built.

DeWalt DCD777C2 is slightly lighter than its sibling here. It is extremely lightweight at just 2.5 lbs. As the effect, you will be able to hold it for a long time without getting tired. Unfortunately, the shape is a bit awkward. It has a longer body, as it measures 12.5 inches from the front to the rear.

DeWalt DCD780C2 is just a little bit heavier at 3.4 pounds. The best thing about this model is the extremely compact shape. The total length is only 7.5 inches. Hence, you will be able to maneuver effortlessly and drill in difficult angles without a problem.

Included Accessories
DeWalt DCD777C2 comes with fewer accessories. The bundle simply includes two batteries, one charger, and a kit bag. Nevertheless, including two batteries in the bundle is a wise idea. It will allow you to swap the batteries and continue working instead of waiting for a recharge process.

DeWalt DCD780C2 includes more accessories. The bundle includes two batteries, one charger, one on-board bit holder, one belt hook, and a hard plastic carrying case. The additional accessories are very useful. The bit holder is definitely very handy for keeping your bits secure yet easy to reach. The belt hook allows for easy carrying when on the field. The hard case can help to protect the drill and accessories when in storage.
