In-depth Dewalt DCD777C2 Review

Ergonomic and Lightweight body

Most cordless drivers are supposed to be compact. However, when it comes to the Dewalt DCD777C2, this tool is even much more lightweight and portable than an average cordless unit.

Accordingly, this drill is 12.5×3.75×9.81 inches large and 2.6 lbs weight. Even more, its design is ergonomics so that you can grip the DCD777C2 without experiencing fatigue. As a result, you can not only extend the drilling and driving sessions but also maneuver in the tight spaces with more stability.

However, professionals who are using heavy units might take time to get used to this lightweight drill.

High-performance brushless motor

Good to know, the Dewalt DCD777C2 is built to be easy to use by beginners, meanwhile, it comes with a powerful brushless motor to meet the demanding requirements of DIY professionals.

In specific, the brushless motor supports the gear to run more effectively with less power consumption because it is cooler than other motors. The max power is up to 340 UWO.

Even better, the brushless is easier to maintain, as well.

Flexible-speed transmission

Together with it, the Dewalt DCD777C2 support variable trigger and two gears of 500 RPM and 1750 RPM. Thanks to this, you can control the machine better: the high revolutions to produce more power and low resolutions to save fuel and complete small tasks. Also, it is possible to regulate the fine-tuning torque and clutch settings to get the right torque output as wished.

Such adjustable features make the DeWalt DCD777C2 versatile for both driving and drilling screws.

User-friendly operation

The Dewalt DCD777C2 is usable almost out of the box with many user-friendly features.

For instance, you can adjust the direction of the driver to fit very tit space by reversing the control knob close to the trigger. Or there is a built-in LED to brighten up the working space in case you need to drill in a dim situation. The light will turn off automatically 20 seconds after you release the trigger.

Affordable pricing

It is a common sense that Dewalt tools are often expensive due to its quality build and powerful performance. But surprisingly, the DCD777c2 turns out to be very cheap for a set of feature-rich drill driver, two Li-ion batteries, charger, and a carry bag.

Plastic chunks

Above are the advantages you can expect from buying the DeWalt DCD777C2. Now, mentioning some drawbacks, we still want the manufacturer to improve its arsenal.

First is the plastic ratcheting chunks. They seem to be vulnerably out of place in the quality-built DCD777C2. Under the continue use and high settings, those chucks can get loose and cause problems like wobbling.

Under-capable batteries

That both batteries and charger are included in the package is a big plus. Nevertheless, we must confirm that those batteries die very fast, especially when you run at a high speed or turn on the LED light. Thus, you should always fully charge the batteries before starting an extensive work.


1. How long does a battery last?

It depends on your usage, for example, the projects and variable capacity. Nonetheless, the batteries are quickly eaten up.

Fortunately, it takes only a couple of hours to fully charge those batteries.

2. How long is the warranty for?

The Dewalt DCD777C2 supports a 3-year limited warranty, along with 1-year free service. You can contact the seller for more information.

3. Is there any battery life meter?

No, there isn’t.

The manufacture must update this feature soon because many consumers complain about this lack.

4. Is brushless better than traditional drivers?


The main difference is, the brushed motor is made of carbon to produce power and the brushless one will make use of magnets. For this reason, the brushless motor is more adaptive, less fiction, and less heating. Besides, this type of motor requires less maintenance and replacement. The only drawback is that brushless is often more complicated.

In terms of Dewalt DCD777C2, the brushless motor is confirmed to be more effective and reduce 30% runtime.

5. Is Dewalt DCD777C2 reversible?

Yes, the drill features various speeds to meet with different projects.

6. What is a keyless chuck?

It is mentioned in the specification that Dewalt DCD777C2 features a keyless chuck. So, how does this part benefit the overall performance?

For your information, the chuck mechanism helps replace the bits faster because you just need to install the bits inside the chuck and twist to tighten the chuck in place.

7. Dewalt DCD777C2 vs. DCD771C2, which is better?

When you search for Dewalt DCD777C2, there is a likelihood that you come across the DCD771C2 several times. In fact, the two are common alternatives to each other.

In similarity, the two are both compact and cordless. Thus, they are portable and straightforward to use. The DCD771C2 also features LED light and some user-friendly features as the DCD777C2.

The difference is the capacity. Despite being smaller, the DCD777C2 is more powerful than its brother. Accordingly, the DCD771C2’s max power is 300 UWO and its maximum RPM is 1500 compared to 1750 of the DCD777C2. As a result, DCD771C2 is less expensive.

In sum, we still recommend DCD777C2 because of its powerful features to handle more projects.

8. What about the DCD777C2 and DCD708c2?

Overall, the Atomic DCD708C2 by Dewalt is another good cordless drill to take into consideration. Not only does the tool smaller than many others like the DCD777C2, but it also run on lower voltage – to be exact, 12V. Consequently, DCD777C2 is less powerful.

In return, this tool is hassle-free to operate and use.

9. How is DCD777C2 different from the XR brushless?

In comparison to the DCD777C2, 20V MAX* XR® Brushless is an upgrade version with enhanced features such as 3 embedded LEDs and the motor that delivers 57% more runtime.

Last Verdict

We call the Dewalt DCD777C2 review a day with all information above. To conclude, this cordless drill driver supports an excellent balance of compact construction and powerful function to complete small to medium drilling tasks. There are still problems with chucks or batteries but they are not serious enough to prevent you from buying.
