Brushless motors produce less friction than their brushed counterparts, and this has several advantages. By producing less friction, a brushless motor can handle more current without overheating, allowing it to reach a higher rpm and greater torque than a brushed motor. If you’re looking for a model to keep around the house for occasional projects and repairs, the best DeWalt drill for home use is the DCD771 in its kit form.

What seals the deal for this model is that the kit is less than $200—a significant drop from the $269 price tag it had when it first launched. That’s on top of the fact that this is a Tool Connect product with smart controls and tracking built in. When it comes to performance, there’s certainly a difference between your 12V Max and 20V Max options. The DCD706 has a top speed of 1500 RPM with 25,500 BPM and 250 UWO. That’s noticeably slower and less than half as powerful as our DCD799 Atomic recommendation.
Most consumers are familiar with drill drivers, which are used to drill holes and drive screws. Another option offered by DeWalt is the hammer driver; those are a bit heavier and get used in concrete and masonry. There were a couple of other features worth pointing out that may help if you’re still undecided. Most drills now come with LED lighting to help with visibility in lower lighting settings.
I suspect that tasks like priming oil pumps and putting holes in sheet metal are sure to give this little drill a workout. Users like it for its ease of use when switching drill bits, as well as the tongue, though many users have said that the battery-charger design could be improved. As it is, the batteries do not channel into the cradle and snap in to clearly let you know that the battery’s seated.
That friction generates a fair amount of heat, leading to as much as a 20% loss in torque efficiency (energy that is transformed to rotational force) compared with brushless motors. Brushless motors work primarily by dewalt tool way of magnets and have no physical, friction-inducing parts. This efficiency gain gets you better performance and drilling power over the course of a battery charge compared with the same drill in a brushed model.
Otherwise, assuming this is your first cordless tool, it comes down to two main factors — performance expectation and price. If you’re only assembling Ikea furniture and hanging shelves, a 12-volt drill is all you need. If you’re planning on getting into more substantial work, longer use times or light construction, you’re better off with an 18-volt. As with other brands of drills, dewalt tools range in chuck size from ⅜-inch to ½-inch models. The chuck size refers to the maximum diameter bit that the chuck can hold. A ½-inch drill produces significantly more torque, making them better able to drill holes with larger bits or drive in larger fasteners such as lag bolts.
It gives the brushless motor enough juice to produce a max speed of 2,250 rpm with a UWO rating of 340. A detachable side handle allows one to get a firm two-handed grip on the drill. Most 12-volt cordless drills are suited for lighter tasks such as mounting a hook in the bathroom and other odd jobs around the home. It sports a brushless motor that gives it significantly more power than a standard 12-volt drill, evident in its 250-UWO rating and its ability to reach maximum speeds of 1,500 rpm. While it may not be on par with DeWalt’s 20-volt cordless drills, it has plenty of juice to handle bigger DIY projects. Drills and drivers use interchangeable bits to make holes and turn fasteners.
It has all the bells and whistles you’ll find among 12-volt brushed drills, but you will pay for all this handy goodness, as this drill is tied for second most expensive in the category. This drill combo kit includes a two-speed driver, screwdriver bit, clutch settings, and precise torque settings for accurate screw driving and drilling. Bigger jobs demand a corded drill with a powerful motor that can produce ample torque. With its 10.5-amp motor, DeWalt’s top-of-the-line corded drill can generate enough power to bore holes up to 3⅝ inches in diameter with a hole saw or 1½ inches in diameter with an auger. It also includes handy safety features that prevent the drill from overheating. Its E-Clutch system reduces the motor’s torque if it encounters resistance that could damage the motor.
Thankfully, DEWALT is offering a $90 discount on its latest drill and driver set, which will cut your work time down significantly. Power tools are expensive, and while it may be easy to keep up with them in a home shop, it can be a challenge for professional contractors managing multiple workers and cordless drills. This cordless hammer drill helps its owner keep tabs on it with DeWalt’s Tool Connect feature that allows the owner to track and find its location via an app on a smartphone.
