Dewalt DCD771C2 vs DCD777C2

Dewalt has been a pioneer in the field of power tools for many decades. With technology developing at a rapid pace in the industry, it was amongst the first brands to offer customers cordless tools that were powered by batteries.

Over the decades, they have released a number of cordless drills that have gained popularity in the market. The combination of power and efficiency at an affordable price makes it the brand of choice for professionals and amateurs alike.

The DCD771C2 was one of the earlier models that became quite successful in the market. Thanks to its performance and ease of access, it was loved by most consumers who purchased this model.

Over the years, Dewalt developed and released the DCD777C2, which was a major leap forward for the company. It introduced new technologies that we will discuss in the next section, as I highlight the major differences between these products.


The most significant difference between the DCD771C2 and DCD777C2 is the motor used. The DCD771C2 has a brushed motor while the DCD777C2 has a brushless motor. 

If you want to know more about the differences between these motors, do read the special section talking about the same.

The DCD777C2 is also the lighter of the two products, weighing over a pound less than its older counterpart. This makes a world of difference when drilling, as the DCD777C2 is easier to grip and maneuver. 

However, the increased weight of the DCD771C2 does a better job at absorbing vibrations, which allows users to maintain better stability. This ensures a slightly better accuracy as a result.

The DCD771C2 has a higher speed, with a maximum of around 1,800 RPM. While this is better than the Dewalt DCD777C2, which has a maximum speed of 1,600 RPM, it does not produce as much power as the latter.

Thanks to its brushless motor, the DCD777C2 is able to produce 340 UWO, which is a considerable increase from the 300 UWO offered by the DCD771C2. 

This was one of the more prominent differences as I felt the power difference instantly when I switched from the DCD771C2 to the DCD777C2.

The DCD777C2 comes with 16 clutch settings, which gives users an extra bit of control over their settings. The DCD771C2 however does not fall behind by too much, offering 15 clutch settings which are more than sufficient.

Coming to the pricing, the DCD777C2 is priced much higher compared to the DCD771C2. This is primarily due to its brushless motor technology and improved design, which increases its efficiency and user experience as a result.


As mentioned above, there are quite a large number of changes that were introduced in the DCD777C2. However, being from the Dewalt brand, both these drills look quite alike, with the trademark yellow and black paint scheme making them easily identifiable even from afar.

Both these models are powered by the 20V MAX lithium-ion battery system from Dewalt. This allows both these models to be compatible with batteries from the same range used in other Dewalt tools.

Another common aspect of both these models is the large oversized ergonomic grip. It allows the user to hold the tool firmly and with ease. 

The rubber grips also ensure that a large number of vibrations during operation are minimized, making for a comfortable user experience.

I was also happy with the fact that both these drills came with their own carry bag. This made it convenient for me to put my drill bits and chargers together in one package, making it easy for me to move around without leaving behind my drilling kit.

A useful feature that can come in handy on both these products is the addition of an LED light.

In situations where the drill may have to be operated in low light conditions, one can simply use the LED light on these drills. This ensures improved accuracy and precision at any given time, be it day or night.

Both these products come with a 3-year warranty from Dewalt. This allows you to return and seek a replacement at no additional cost if the product is faulty due to a manufacturing defect.

Despite being on the slightly heavier side, I found this to be one of the most balanced drills available at this price point. 

Being a compact drill, it also allowed me to fit the drill in hard-to-reach spots, allowing me to get the job done without any hassles.

  • Compatibility with the 20V MAX system

As most of you know, I have a variety of Dewalt cordless tools to suit my professional requirements. Almost all of them belong to the 20V MAX system, which offers great battery performance in terms of charging and run time.

With the DCD771C2, I could interchange it with any of the existing batteries I had. As a result, I did not have to purchase batteries with higher Ah for outdoor applications. 

This allowed me to use the drill for longer in remote locations while having plenty of backups if and when required.

I was also quite happy with the rapid charger provided along with the drill. This allowed me to have a fully charged battery in around an hour, which allowed me to complete my jobs quickly as a result.

  • User-friendly features

The DCD771C2 offers a number of user-friendly features, staying true to the design ethos of Dewalt and its tools. This includes an LED work light, a keyless chuck design, and a reverse feature.

The LED work light was one of the most useful features that I benefited from on a number of occasions.

This allowed me to work at night without requiring additional lights from my workshop. I was also surprised at how it did not get blocked much by my hand, which ensured the working area was illuminated properly.

The keyless chuck allowed me to change bits without having to use specialized tools to do so, helping me save time in the process. 

I was also grateful for the reverse feature that allowed me to remove a bit from the hole without damaging the bit or chuck in the process.

Dewalt DCD777C2 Review

With the sudden rise in popularity, and thus demand for brushless drills, Dewalt introduced the DCD777C2. This offered a few upgrades to the existing design of the DCD771C2 while retaining the classic features that made its predecessor a big hit.

Coming in the classic black and yellow paint scheme of most Dewalt power tools, it has quite a noticeable difference in terms of performance. 

The reduction in weight and improved power delivery were things that I noticed quite early into using the product, which enhanced my user experience.

I was also glad that Dewalt retained a few features from previous models that worked well for most customers. This included the addition of two Li-ion batteries, a charger, and a carry case on purchase of this model, as well as 3 years warranty from the manufacturer.


  • Powerful and smooth performance

Thanks to the incorporation of the brushless motor technology, the DCD777C2 offers better power delivery and increased output. This was despite the slightly lower maximum RPM speed of this drill compared to the DCD771C2.

While it may seem negligible to some, I found the additional power quite useful in a few tasks that needed more power than most lightweight applications.

I also liked the fact that this tool felt a lot more refined as a result, which allowed me to be more precise during drilling. I was also impressed by the reduced noise levels, which made sure that I was not a disturbance to the neighborhood while working.

  • Lightweight and compact design

Being a small drill meant for lightweight work, I was surprised at just how compact the drill was from chuck to handle. 

The smart design incorporates all the necessary features, while also managing to provide quite a large gripping surface.

The reduced weight was noticeable as soon as I took the product out of the box. Together with the battery, it felt quite easy to operate with a single hand. Any worries I had about increased vibrations were taken care of by the rubber grips and motor.

To emphasize its lightweight design, one of my elderly neighbors requested the drill for a small house repair. 

He was so surprised at just how easily he could use it, and wanted to know more details about the DCD777C2, which he eventually ended up purchasing!

  • Forward and reverse option

At this price point, having a forward and reverse option can make your life a whole lot easier. I did not have to wrestle the bit out of the hole I had just drilled.

Instead, all I had to do was press the direction switch near the trigger, which reversed the direction and allowed the bit to come out smoothly.

This can also be important if you are someone who likes to take care of their drilling bits. You will not have to worry about the bit snapping off while removal, as the force on the bit is applied uniformly across the central axis, which reduces the forces acting on it vertically.

Pros and Cons


  • Brushless technology reduces vibrations and noise considerably
  • Compatibility with the 20V MAX battery system, quick charging
  • Offers good amount of power for a compact drill
  • Direction reverse option for forward and reverse drilling
  • 3 years manufacturer warranty


  • Quite expensive compared to other drills with similar specs
  • Not designed for heavy duty work
  • Reverse button gets in the way of trigger operation
  • Complaints of gearbox failure after relatively short time periods

Difference Between Brushless and Brushed Motor

As highlighted above, the main difference between the DCD771C2 and DCD777C2 is the type of motor they use to rotate the drill, with the former being a brushed motor and the latter using a brushless motor.

In this section, I go into the details of these differences to help you get better clarity. This will assist you in deciding the ideal drill model for you.

A brushed motor consists of commutator brushes that help spin the shaft within the motor. However, these brushes are replaced by a permanent magnet in the brushless motor mechanism.

While the brushless mechanism is a more complex method of rotating the shaft, it is also the most efficient way of doing so as it eliminates friction between the brushes and the shaft. They are also much quieter as a result. They require less maintenance and can last for longer durations.

On the other hand, a brushed motor offers simplicity in design but lacks efficiency due to losses caused by friction. They can be much noisier for the same reason as well. They also require periodic maintenance of the brushes and tend to have a shorter lifespan as a result.

Another advantage of brushless motors is the increased torque and performance that they can provide due to the permanent magnet and alternating the current using controllers. This also improves the dynamic response, allowing the motor to respond faster to user inputs.

In the case of brushed motors, the performance is limited by the brushes, which cannot allow the shaft to rotate beyond certain speeds. It also leads to a sluggish motor response on the input of the user.

However, brushless motors are much more complex to build and design, making them much more expensive and difficult to repair. The simple mechanism of the brushless motors is easy to make, making them the choice of most household appliances for reduced cost and ease of repair. 


  • Is Dewalt DCD771C2 a hammer drill?

    No, the Dewalt DCD771C2 is not just a hammer drill. In fact, it is a hybrid model that has a hammer drill mode as well as an impact mode. 

    The hammer mechanism is more useful in situations where one needs to drill holes into harder materials like concrete. ON the other hand, the impact drill mechanism is better for softer materials that are more susceptible to cracking on heavier impacts.

  • Is DeWalt DCD777C2 variable speed?

    Yes, the Dewalt DCD777C2 has a variable speed setting that can be controlled using the trigger. There is also a higher torque and lower torque setting depending on the purpose of use that can be changed before operating the drill.


At the end of this DCD771C2 VS DCD777C2 comaprison, I was personally much more impressed with the Dewalt DCD777C2 compared to the Dewalt DCD771C2. If you have any questions regarding our DCD777C2 VS DCD771C2 comparison you can drop them in the comment section below.

Despite being the more expensive model of the two, I was quite pleased by the improvement in performance that I was paying for. I always consider buying a new tool as a long-term investment, which convinced me that this product would give me better returns in the long run.

While the differences were evident, the fact that the drill was lighter and more efficient was the game changer for me. 

Being someone who works with power tools day in and day out, it was a big relief that this drill was lightweight. This allowed me to work for longer hours without feeling the strain in my arm.

I have always made it clear that companies offering a unified battery system like the Dewalt MAX 20V have changed the way we use cordless tools. On the DCD777C2, this was an even better experience thanks to the increased runtime I was able to get while outside.

At the end of the day, the DCD771C2 is not a bad drill, especially considering its budget-friendly pricing. However, the DCD777C2 adds a level of professionalism that makes it a much more preferred impact drill for handymen like me.
