DeWalt is a familiar brand name, and the company has a long history of producing some of the best power tools on the market. DeWalt's DCD790D2 cordless drill lives up to this reputation. The drill has 20 volts of power running through its system, which allows it to pack quite the punch. With easily adjustable speed and clutch settings, you can use this drill for a variety of projects. This is one of the best cordless drills we reviewed, and it earns our Top Ten Reviews Silver Award because of its high user-experience rating, fast turning speed and overall good design.
To determine which cordless drill is the best, we put together a team of more than a dozen expert reviewers. After using the drills, each reviewer completed a survey about their experience. They rated each drill on a scale of one to five (one being the worst and five being the best) based on its balance, handling, power, weight and grip. When we calculated the results, the DCD790D2 scored 3.22 for balance, 3.86 for handling, 4 for power, and 3.82 for both weight and grip. When compared against the average for all the drills we reviewed, the final user-experience grade came out to a B+. The highest scoring prodct in our survey was the Makita XFD10R.
The DeWalt DCD790D2 is a powerful drill that can handle tough jobs with ease. It runs off 20-volt batteries, which allow it to turn at a maximum rate of 2,000 RPM. This is the fastest turning rate of all the drills we reviewed. You can also adjust the speed between two settings to tackle different jobs. On the low setting (0 to 600 RPM), you can use the drill as a screwdriver. The higher setting is for high-intensity tasks like boring holes through wood.
This drill comes with two 20-volt lithium-ion batteries. In our battery life test, we attached a fully charged battery to the drill and taped the trigger in the on position. We then timed how long it took to drain power completely. The batteries DeWalt provides lasted 43 minutes, which was above the average of 39 minutes. For comparison, the longest lasting battery ran for over an hour. So, you can expect the batteries to last a good while – just make sure you have the extra one on the charger. It only takes about 35 minutes to fully recharge a dead battery.
Unfortunately, DeWalt doesn't release the drill's torque specification. Instead, the company lists its power rating, which takes into account the tool's speed and torque, resulting in a measurement of unit watts out (UWO). According to DeWalt, power is the amount of work completed in a given period of time, which basically means the higher the power rating, the faster the drill can complete a job.
The problem with this system of measurement is that it doesn’t compare with the traditional industry standard, torque. We contacted a representative from DeWalt, and they said that there isn’t a way to compare the drill's power rating with another brand's torque rating. As such, we were unable to compare the DCD790D2's power rating of 360 UWO to the torque specs all the other drills we reviewed have.
This drill only weighs 3.5 pounds, which is great, as heavy drills can wear you out quickly. The design is incredibly comfortable because part of the weight is distributed below your hand, so it is very balanced. The drill has a half-inch keyless chuck, meaning you tighten or loosen bits to the drill by hand. With this feature, you don't have to worry about misplacing a key, which is especially frustrating when you are on the top of a ladder and need to switch bits.
You can choose between 15 clutch settings on this cordless drill. This allows you to fine-tune how much torque you want to use based on your project. Fifteen options is good enough for most cases, but other drills we reviewed have up to 24. In fact, this DeWalt models has the fewest clutch settings of all the drills we evaluated.
The DCD790D2 has an LED light that illuminates the area in front of you. The light has a 20-second trigger release delay, which is more useful than you'd think, and it’s located at the foot of the tool so the chuck doesn't cast any shadows around the area. You also have the option to attach a bit holder to the tool so you can carry a variety of sizes or extras with you.
DeWalt offers a three-year warranty on the drill and another three years on the batteries. If you run into any manufacturing errors or defects, the company will repair the tool without charge. The warranty doesn’t cover part failures caused by normal wear or tool abuse. If you have any questions or concerns, you can contact the company via email or telephone. DeWalt also has online user manuals and FAQs pages you can check out.
The DeWalt DCD790D2 is a heavy contender in its class of drills. Unfortunately, the company does not release the tool's torque information. While the power rating system the company uses is useful for comparisons between its own tools, there is no way to compare torque to power. However, the drill has a decent battery life and a great three-year warranty that covers any defects. Overall, this is one of the best cordless power drills we reviewed because of its speed, battery life and comfortable design.
