DEWALT DCD791D2 vs DCD991P2 Review

DEWALT is a trusted name in tools. If you’re looking for a new cordless drill, they have many models to choose from. Let’s look at two of them to see which is the best for you.










DEWALT DCD791D2 20V MAX XR Li-Ion 0.5″ 2.0Ah Brushless Compact Drill/Driver Kit

The DCD791 drill/driver has a brushless motor which makes this is a pro’s tool. A brushless motor runs double the amount of time on a single charge, it runs cooler, and has more power than an ordinary brushed motor. Plus, the DCD791 is compact, lightweight, and feels good in your hand. It weighs just 3.4 pounds and measures only 6.9 inches, back to front. The center of gravity is right above its grip so it stays balanced as you work, not like the hard to control pistol grip drills of the past.

The two-speed transmission gives you flexibility to choose how to tackle a job. The low speed runs up to 550rpm and the high up to 2000rpm. The ½-inch ratcheting metal chuck grips bits firmly even on tough projects.

If you’re working in a dimly lit area, the three LED lights will help you see exactly where you’re drilling or driving without the use of an additional lamp. In fact, the DCD791’s lights have a spotlight function that lets them run up to 20 minutes at a time even though you’re not otherwise using the tool.

Just because this is a cordless drill doesn’t mean it lacks torque. It’s rated for 460 unit watts out, or over 600 inch-pounds of power. That’s great for working in hard woods or metal. If you plan to sink fasteners in masonry, check out the DCD991P2 hammer drill below.

More features of the DEWALT DCD791D2 cordless drill kit:

  • DEWALT offers a 90-day money-back guarantee, 1-year free service, and a 3-year limited warranty
  • Comes with charger, two 2.0Ah XR battery packs, belt hook, and kit box


DEWALT DCD991P2 20V MAX XR Lithium Ion Brushless 3-Speed Drill/Driver Kit

If you liked the DCD791 drill driver described above, but need something for working with concrete or rock, the DCD991 hammer drill might be the perfect solution for you. Like the other tool, it’s powered by a brushless motor for long runtime and maximum torque.

It has a three-speed all-metal transmission that ranges from 450 to 2000rpm. Since it’s a hammer drill, it’s made to stand up to really tough jobs. It has a maximum torque of 820 unit watts out for drilling and driving into masonry and metal without binding and choking.

It’s a good thing DEWALT built the DCD991 with a heavy-duty ½-inch ratcheting chuck with carbide inserts. Anything less wouldn’t be as good at gripping bits when the drill has so much power.

Like the DCD791, the DCD991 has three bright LED lights with a special spotlight mode. You’ll do fine working in dim places even if you’ve forgotten your other lamps. Since this drill comes with two 5Ah lithium-ion battery packs, you don’t need to worry about running out of juice.

Although the DCD991 is a hammer drill, you can turn off the hammer function and use it for driving and drilling in soft woods and plastics. It weighs just 4.6 pounds and the weight is nicely balanced right over the handle. It comes with a removable side handle for hammer drilling. That extra handle rotates 360 degrees so you always have the right grip on the tool.

More features of the DEWALT DCD991P2 cordless drill kit:

  • DEWALT offers a 90-day money-back guarantee, 1-year free service, and a 3-year limited warranty
  • Comes with charger, two 5.0Ah MAX XR battery packs, side handle, belt hook, and kit box



Instead of choosing between these two drills, why not get them both? But if you only want one, consider what materials you plan to drill the most.

If your work is primarily in masonry, like sinking anchors in concrete, get the DCD991P2 kit. It’s a hammer drill that comes with two long-life battery packs. You can also turn off the hammer function from the clutch ring and use it as a regular drill/driver for soft materials. The 3-speed transmission makes it a precision tool.

If you work in plastics, woods, or metals, get the DCD791D2. It’s a pro tool for a variety of jobs all around the worksite.
