1. DEWALT 20V MAX XR Hammer Drill (DCD996B)

DEWALT 20V MAX XR Hammer Drill (DCD996B)
View on Amazon
The DCD996B model presents a middle price category hammer drill, which provides exquisite performance despite its affordability. The tool features all the advantages of the 20V MAX XR series common for other DEWALT drills.

First of all, the manufacturer equipped it with a high-efficiency brushless motor and high-performance transmission for improved power and runtime. The tool can drill all types of masonry materials and do it twice better and faster than previous generations of hammer drills.

DEWALT DCD996B is an excellent option for the toughest works as its ratcheting chuck was also reinforced. The unit is made of durable nitro-carburized metal.

Users are free to switch between 3 speeds as well as 3 LED light modes. Customers note the ease of application even in tight areas thanks to compact and quite light design. Besides, a coated and sealed body is resistant to moisture and dust.

Currently, Amazon offers the item for $129. You’ll get the tool only.

View on Amazon
The DCD996B model presents a middle price category hammer drill, which provides exquisite performance despite its affordability. The tool features all the advantages of the 20V MAX XR series common for other DEWALT drills.

Though the previous model has almost no minuses, there is always space for improvements. That’s how the manufacturer thought when developing the DEWALT DCD997CB tool. The DCD996B vs DCD997CB comparison will show literally identical design and filling except for one great addition – integrated Bluetooth technology.

Owners of this model can connect this hammer drill to the DEWALT Tool Connect free mobile app and get dozens of maintenance and control opportunities. The app allows for customizing the tool, conducting diagnostics on the battery life, temperature, the number of trigger pulls, receiving alerts, and even tool tracking.

The latter is possible thanks to the Last Seen feature. Thus, you can find your lost tool and disable it if it was stolen.

When speaking about other characteristics, they are absolutely the same as in the DEWALT DCD996B hammer drill.

This smarter power tool will cost you about $179. Once again, the battery is not included.

3. DEWALT 20V MAX XR Rotary Hammer/Drill Combination Kit (DCD998W1)

DEWALT 20V MAX XR Rotary Hammer/Drill Combination Kit (DCD998W1)
View on Amazon
Not always bare tools can satisfy a customer. If you don’t have batteries and storage units from your previous instruments, their purchase will become additional financial expenses. In such cases, it’s better to look for a kit.

DEWALT took care of this and launched the DCD998W1 combination kit. You get a nice storage bag, belt clip, and a side handle. Moreover, when it comes to the battery, DCD996B vs DCD997CB vs DCD998W1 battle ends with the unconditional victory of the last tool over all the above discussed. The unit comes with a 20V MAX 8Ah battery and charger.

The kit is the main reason for purchase and higher $249 price. Other characteristics include a brushless motor standard for the series, 3 speeds and LED modes, heavy-duty 1/2 in ratcheting nitro-carburized metal chuck.

Please pay attention that this model can boast of even more powerful and durable operation due to Power Detect Tool Technology. The system maximizes performance by 29%. Besides, the body became significantly lighter.

4. DEWALT 20V MAX XR Brushless Drill/Driver (DCD791B)

DEWALT 20V MAX XR Brushless Drill/Driver (DCD791B)
View on Amazon
The DCD791B is definitely the best budget option. This model is aimed at preserving a balance between high performance and affordability. However, a lower price means certain sacrifices. Let’s look at them closer.

Undoubtedly, the manufacturer kept an innovative brushless motor. We also note the same 3 LED modes. But this time, we have only 2 speed settings.

The chuck alloy also became simpler – engineers used metal without any reinforcements. Engineers managed to reduce weight even more but reduced sealing protection.

In a word, the DEWALT DCD791B is a simpler power tool for less complicated hammering tasks. The manufacturer placed a bet on its «driver» application.

This tool will provide you with 15 clutch settings, which is 4 more than all other DEWALT hammers have. So, if you’re looking for a multi-functional yet budget device for common domestic work, this product is for you.

As usual, customers get a bare tool, and the battery and charger are sold separately. At the moment, the price stays under $100.

Pros
  • ultimate MAX XR power and durability
  • perfectly copes with most domestic and semi-professional tasks
  • can be used as a driver
  • more clutch settings
  • uses a brushless motor
  • high-performance transmission
  • 2 speeds
  • 3 LED modes
  • 1/2 in. metal chuck
  • The most lightweight body
  • the best price
Cons
  • battery and a charger come separately
  • fewer speeds and simpler chuck
  • not for the toughest tasks

5. DEWALT 20V MAX XR Cordless Lithium-Ion Compact Hammer Drill (DCD796)

DEWALT 20V MAX XR Cordless Lithium-Ion Compact Hammer Drill (DCD796)
View on Amazon
The final representative of DEWALT cordless hammer drills also occupies the medium position in terms of power. It’s 57% more potent and durable than non-XR tools but loses in comparison with the first three DEWALT hammers discussed.

Mostly, it’s similar to the DCD791B tool. Besides, DCD791B vs DCD796 comparison reveals literally two differences – lightweight design and less number of clutch settings.

Once again, we get 2 speed options. Though professional craftsmen may find it insufficient, two speeds won’t be an issue for domestic use as many people never need to apply the high power.

Analogically, the tool is suitable for double use as a hammer drill and as a driver.

Cost varies from $100 to $120 per item, but it depends on the sales. It seems that we also can expect price reduction in connection with the growing popularity of other 20V MAX XR appliances.

Pros
  • 57% more MAX XR power and durability
  • perfect for domestic, DIY, and semi-professional use
  • can be used as a driver
  • equipped with a brushless motor
  • high-performance transmission
  • 2 speeds
  • 3 LED modes
  • 1/2 in metal chuck
  • the most lightweight body
  • budget price
Cons
  • battery and a charger come separately
  • fewer speeds and simpler chuck
  • not for the toughest tasks
Now when you got familiar with the DEWALTs main strong and weak sides, let’s go deeper into characteristics comparison.

Face to Face Comparison

Design and Dimensions

When we speak about power tools for tough tasks, dimensions are as crucial as never before. The weight and size of your hammer drill will significantly influence how long you’ll be able to work with it and how comfortable it will be. Besides, small models can reach more places.

Here is the list of dimensions for all five DEWALT models discussed:

DEWALT DCD996B:

Dewalt DCD996B

  • 4″ x 10″ x 8″
  • 4 pounds

DEWALT DCD997CB:

Dewalt DCD997CB

  • 10.08″ x 9.02″ x 4.17″
  • 4.43 pounds

DEWALT DCD998W1:

Dewalt DCD998W1

  • 8.85″ x 2.55″ x 8.2″
  • 3.5 pounds

DEWALT DCD791B:

Dewalt DCD791B

  • 8.31″ x 3″ x 7.56″
  • 2.7 pounds

DEWALT DCD796:

Dewalt DCD796

  • 7.5″ x 2.5″ x 8″
  • 2.7 pounds

As you see, drills’ height, length, and width don’t vary so much. But the last two models offer the best weight.

The design of the tools doesn’t provoke any diversity. The brand uses its traditional black and yellow colors. All items are made of metal and plastic, and we’d like to separately note rubber covering on grips for better contact with the hand.

Motor

Motors have been scrutinized in the description section. So let us just quickly remind you that absolutely all DEWALT tools of the 20V MAX XR series, including our five hammer drills, are equipped with brushless motors of the new generation.

According to the manufacturer, such motors consume 57% less energy but provide double power. It results in longer battery life and higher performance.

The voltage required is 110-120 volts.

Speeds and Rotations Per Minute

Speed transmission Dewalt
Here all models can be divided into two groups.

  • The first group includes the DEWALT DCD996B, DCD997CB, and DCD998W1 drills. These tools offer as many as three speeds for 450, 1300, and 2000 RPM. Max power measures 820 UWO (Units Watts Out). Blows per minute rate reaches 38250 BPM.
  • The second group unites two other appliances, the DEWALT DCD791B and DCD796. These hammer drills have two speeds, which are 550 and 2000 RPM. Though rotations stayed the same, max power dropped to 460 UWO. And when it comes to blows, they were also slightly cut to 34000 BPM.
Verdict: The difference between the groups is not too great, but it influences the performance. The first three drills are omnipotent. The others won’t suit extreme professional challenges.

Chuck

Chuck Dewalt
Chuck size unites the models. It measures standard 1/2 inches and suits most bits and drills. Moreover, its keyless design allows for using one hand only for quick replacement.

However, more powerful hammer drills require more durability and reinforcement.

  • That’s why the first three tools come with a nitro-carburized metal ratcheting chuck with carbide inserts for superior bit gripping strength.
  • DEWALT DCD791B and DCD796 have simple metal chucks usual for most hammer drills and drivers.

Clutch Settings

Clutch Settings DewaltAs long as all models are 2-in-1 tools that can be used as hammer drills and drivers, the number of clutch settings is quite important.

The most powerful DEWALTs and the last DCD796 offer 11 settings.

Among all drills, only the DEWALT DCD791B comes with an extended number of settings. Here we have 15 options.

Clutches are quite easy to set. Some users complain about weak holding, but during tests, we noticed no issues.

LED

Mode LED DewaltAll hammer drills are equipped with convenient LED lighting with 3 modes, including the Spotlight mode. Thanks to this system, users can conduct work in dark or confined spaces without the need for additional lighting.

Besides, the brand claims this lighting is up to 20X brighter than previous models.

The worklight and its switch are located on the foot of the tool. The worklight is activated when the trigger switch is depressed. You can also change the modes by moving the switch on the foot of the tool.

There are Low, Medium, and Spotlight options. On Low and Medium settings, the beam automatically turns off 20 seconds after the trigger switch is released. The Spotlight will run for 20 minutes after the trigger switch is released.

Batteries

DEWALT Battery
View 20V MAX XR 8Ah Battery on Amazon
Among five hammer drill models, only the third product DEWALT 20V MAX XR Rotary Hammer/Drill Combination Kit (DCD998W1) comes with a battery and a charger. Here, we get one 8Ah battery.

Others are sold as bare tools. The manufacturer supposes that customers should either have batteries from their old DEWALT tools or purchase a new XR unite separately.

Attention! Hammer drills are compatible with older batteries, but the highest power and durability are possible only in pair with the 20V MAX XR batteries. They are 60% more durable than the 20V MAX kits.

You can choose between several options of various price and capacity. Units cost from $75 (for 5Ah) to $150 (for 8Ah). The brand cannot provide an exact runtime as this would depend on many different variables as well as other environmental factors. However, we can say drills run for a couple of hours.

The maximum initial battery voltage is 20 volts. The nominal voltage is 18 volts.

Verdict: Frankly speaking, the lack of a battery is a big disadvantage for us. If you could use older batteries with the previous series, there is no sense to buy the latest XR power tools and equip them with old batteries. Not only do you spend money on an additional purchase, but you also have to waste time looking and waiting for the unit to come. That’s why the DCD998W1 is a clear winner here.

Accessories

Four out of five kits offer tools only. But DEWALT DCD998W1 is an exception. It is a full kit that includes:

  • one DCB208 20V MAX Lithium-Ion 8.0Ah Battery
  • one charger
  • one belt clip
  • one side handle
  • one kit bag
Thus, if you’d like to get the ultimate performance and full equipment, choose the Combination Kit.

Other models will be worthy in terms of accessories if you already have batteries and storage bags or are ready to make extra investments.

Guide – How to Choose the Best Hammer Drill?

If you have faced the question of how to choose a hammer drill for your home or professional tasks, try to consider the following moments:

  • What is the amount of work to be done?
  • How often are you going to use the tool?
  • What types of surfaces are you supposed to work with?
  • What are the scopes of application, depending on the additional capabilities of the tool?
  • What is your price range?
Dewalt Hammer Drills
Among the rich assortment of power tools for domestic and professional application, it’s extremely important to mind the key characteristics that influence performance.

Power.
Power must be considered to provide proper loading and performance. Drill power allows for using it on tough materials and conducting continuous works.
Rotations and speed.
Working success will also greatly depend on your tool’s speed. Rotation speed indicates the number of revolutions per minute. Please pay attention to the possibility of speed adjustment. This is necessary when performing various kinds of finishing work. Several speed settings also mean the ability to work with different materials.
Chuck.
A hammer drill can be equipped with a keyless or serrated chuck. The latter type is classic, where drill change is performed with a special key. The keyless method allows you to install a new unit in a fairly short time. The quality is equal in both cases, but it’s important to mind it to pick up the most suitable and beneficial option.
Impact strength.
Hammer drills may significantly vary in terms of impact strength. Some have a percussion function that can be turned on and off as needed. This option allows you to work with the hardest materials like concrete, brick, metal. In addition to rotational movements, the axis of the device performs shock «forward-backward» jolts. However, the household hammer drill models are not designed to be used continuously on concrete in a domestic environment. Please also mind that drills are not suitable for woodworking as the tool can cause cracks in the wood.

When deciding which hammer drill to choose, pay attention to the models where the hammer function can be disabled. Such appliances will be truly versatile tools capable of dealing with both wood and harder materials.

Screwdriver function.
One such device can both drill holes and screw fasteners into them. This tool can do most of the household chores: hang a picture, screw shelves and handles, assemble and disassemble furniture. Users love them for compactness, nice power, and relatively silent operation.
Battery.
Cordless hammer drills are distinguished by mobility, the ability to work in places far from electricity sources. The type of battery is important. The choice depends on the frequency of use. Rechargeable Nickel-Cadmium batteries are not designed to be stored on a shelf for extended periods. Their purpose is frequent use and work with soft materials.

Lithium-Ion and Hybrid battery models are more powerful and feature a longer service life. But we’d like to note the need for constant recharging of the tool.

Grip and weight.
The shape of the handle is an important parameter for a hammer drill. Classic models are represented by pistol-shaped grips. They are comfortable when performing any actions, but they tire the hand. To avoid such inconvenience, please pay attention to the tool’s weight (the lighter, the better). Also, try to choose models with trigger fixators.
