Both professional craftsmen and regular Joes can benefit from drill drivers. This type of power tool combines what regular drills and impact drivers do into a single versatile tool. These tools are designed to both drill holes and drive screws into various surfaces or pieces of material without having to outsource each task to separate power tools.
If this sounds like something that could potentially become a valuable part of your toolset, then it’s time to find the right drill driver to suit your needs. The problem is that the market is saturated with manufacturers and their drill driver models.
One of the most popular power tool manufacturers on the planet is DeWalt. They are an American company that specializes in producing power tool and hand tools for the construction and woodworking industries. Two of their most well-known drill driver models are the Dewalt DCD771C2 and the Dewalt DCD777C2. Despite their similar model names, there are some notable differences that we are going to explore in this article.
Let’s begin by taking a glance at the DeWalt DCD771C2 cordless drill driver. You will be excited to discover that this cordless power tool is powered by a 20V Li-Ion battery. The battery provides enough runtime and power to complete most of your projects with just one single charge. Because it is a Li-Ion battery, you’ll get additional power for less added weight.
Upon purchasing this kit, you’ll receive two high-performance batteries that will take you through a whole day’s work (while one is in use, the other can rest in the charging dock to refuel). This tool offers 300 unit watts out (UWO) to cover a wide selection of applications so you won’t have to stress over using several tools for similar tasks.
For experienced users, having control over your power tool is everything. This ½-inch drill driver model by DeWalt gives users complete control over how much power you need to get the job done. This tool comes with two preset speed settings: 0 to 450 RPM and 0 to 1,500 RPM. The slower setting is used for when working with delicate materials and surfaces, and the faster speed means more power for drilling and driving into denser ones. The variable speed control is easy to use, using the clutch setting implemented onto this model.
Although this cordless drill driver is not the lightest one available on the market (3.6 lbs with batteries), it has an ergonomic design and handles extremely well. This is a durable power tool which can last for several years if treated well, and the grip offers ultimate comfort in the hand and control against vibrations.
You can use this tool all day and hardly feel the shock up your arm. It’s also a compact piece of equipment (9.8 inches from front to end) so using it in tight spaces won’t be as challenging. Plus it comes with LED lights located on the unit’s head near the ½-inch chuck.
Some Minor Issues
Common problems with this unit are the chucks inability to grasp tightly onto bits so you’ll need to spend time having to retighten the chuck and the DeWalt-produced Li-Ion batteries that tend to rapidly deteriorate after extensive usage.
Next, let’s take a quick look-see at how the DeWalt DCD777C2 model fares against the previous one. Essentially, this is an entry-level product but comes with some pretty impressive hardware. It features a brushless motor – a hallmark of professional-grade equipment – which runs cooler and much more efficiently, effectively extending the lifetime of both the battery and tool. In addition, one battery charge on a power tool with a brushless motor can power the tool for up to 50% longer.
The DCD777C2 has a 340 UWO rating which is marginally better than the DCD771C2 model we talked about earlier. This machine features two transmission speeds (0 to 500 RPM and 0 to 1,750 RPM) which makes for effortless work in sinking fasteners into delicate materials or drilling into dense ones like metal. The two gears are controlled using a conveniently located variable speed trigger for when you need to constantly switch between the two speeds.
Another notable feature is that DeWalt replaced the metal chuck on the DCD771C2 model with a plastic one on the DCD777C2. The ½-inch chuck suppers a wide selection of bits and accessories. The compact build (9.8 inches from front to back) also makes it an easy-to-handle power tool in constricted spaces.
This lightweight unit (2.6 lb without batteries) is well balanced and comes with a rubber, anti-slip grip for firm control. There is also a single LED light that shines below the plastic chuck. The light has a 20-second delay before shutting off, but it hardly drains the 1.3 amp battery that comes with the kit.
Some Minor Issues
Some problems with this model are that it’s a costly alternative compared to other drill drivers, including the DCD711C2 model, and the kit doesn’t include a bit holder for when you need to change bits between jobs. These aren’t exactly dealbreakers, seeing as how the quality of the unit definitely offers value to professional and DIY-aficionados, but they are important factors to consider when shopping for the right power tool.
When looking at the two models simultaneously, there’s virtually hardly any difference. One can automatically judge from the names of the models that they are extremely similar, come with similar features and designs, and can be used in similar applications.
The main difference is that the Dewalt DCD777C2 model uses a brushless motor which provides both additional power (+40 UWO) and extended battery life. The drawback is that the latter model requires a greater commitment to purchase and appreciate its true value. Both drill drivers perform almost identically in the field, but the additional power with the DCD777C2 is just what you need to perform optimally on denser materials like metal and hardwood.
