Why Buy a Cordless Hammer Drill?
Cordless hammer drills have many advantages over their corded rivals. As we said in the introduction, they are portable, convenient and they improve safety, no matter what the setting.
Imagine needing to work on a task located some distance from a plug socket. First, you have to locate the nearest power outlet and then find an extension cord long enough to reach. Second, if you are working on a job site, this presents challenges because it is a trip hazard for you and your colleagues.
Another top reason for buying a cordless hammer drill is that you can take it anywhere. It’s why so many professionals use them. As for convenience, snap in a fully charged battery, and you are ready to go.
How Do I Choose a Cordless Hammer Drill?
There are many plus-points for cordless hammer drills, and you should consider each carefully when matching a drill for your needs.
Weight
Cordless hammer drills are heavier than corded varieties. This is due to the added weight of the battery. Most cordless hammer drills weigh between 6 and 10 pounds, compared to half that for a corded version.
That said, seek out the lightest option if you are using the drill all day. Hand and wrist fatigue is a real issue for professionals.
Clutch
A clutch is what sets a cordless drill apart from a plug-in variety. The clutch allows the drill motor to disengage when the maximum torque is reached. It stops you from burning out your drill and damaging the gears.
You know the clutch has engaged when you see the drill bit stop, and the drill makes a loud ratcheting noise. Some of the better hammer drills allow you to set the maximum torque.
Speed
Cheaper drills only have one speed. Look for one with adjustable speed settings. Drilling through masonry and concrete differs from other applications in that speed is less important, and torque plays a higher role. Slow and steady wins the race if you get what we mean?
That’s why adjustable speed drills are the best because they can cater to different tasks.
Motor
If you want the most efficient motor, go brushless. It extends the lifespan of your drill, keeps it from overheating during prolonged operation, and best of all, it extends the life of your batteries by up to 50 percent in some cases.
Beats Per Minute
Hammer drills are percussive tools. Percussive is the action of striking something. Inside the drill, an anvil slams into the chuck to create a downward force. This is where it gets its hammer credentials. Beats per minute (BPM) is the number of times the anvil strikes the chuck each minute.
It doesn’t take a genius to work out that the higher the BPM, the better the drill is.
Charge Time
Some of the best cordless hammer drills have super-quick chargers that will get your battery from zero to full in 30 minutes. If you work on-site, this is invaluable because it means you will never run out of juice.
Cheaper models can take up to 5 hours to produce the same results.
Batteries
Most cordless hammer drills have lithium-ion batteries. They are better at holding a charge, delivering the power more efficiently and having a longer lifespan. Older or cheaper models have Nickel Cadmium (NiCad) batteries that are less efficient and far more dangerous for the planet. Cadmium is highly toxic.
Voltage
In the cordless world, voltage is king. What we mean is if you want power, look at the voltage. In the US, most cordless hammer drills are 20 volts. Hammer drills rarely have less power than that because you need all that power for them to be effective.
Drill drivers have less voltage because they are used in less demanding situations.
Keyless Chuck
Time is money on a job site, so with a keyless chuck, you get a more efficient tool. Simply slot in the bit and press the trigger while gripping the chuck. Also, how many of us have lost chuck keys at crucial moments?
Keyless is the way to go.
The Best Cordless Hammer Drills of 2021
1. Milwaukee 2712-20 M18 Fuel Rotary Hammer Drill
Milwaukee is one of those great American power tool brands. This model has a slotted drive shaft (SDS), meaning that it only accepts specialist bits that match. But that’s a good thing because when the drill bit is inserted, you get zero slippage when drilling tough material.
It has a brushless motor, which requires less maintenance and delivers the power from the battery more efficiently. This increases the runtime between charges.
Why We Love It
SDS Chuck
The slotted drive shaft is ideal for when you are drilling through the hardest surfaces. It doesn’t slip in the chuck. Also, it is super-easy when you need to change bits in a hurry.
Great Brand
As we’ve said already, Milwaukee is an American brand that generations of people will know. It has a long and trusted history in the US.
Weight
At 5.5 pounds, this drill packs a punch. The good news is that you will suffer less with hand and wrist fatigue after long periods of use.
Anti-Vibration System
Milwaukee has fitted this model with an anti-vibration system to minimize wear on your hands and wrist.
Warranty
This drill comes with an industry-leading 5-year limited warranty. It means you can buy with confidence.
Keep In Mind
Made in China
While we have mentioned Milwaukee’s history as a great American brand, like others, they have outsourced the manufacturing process to China to save costs. If you like to buy American-made, this is not the drill for you.
Cost
Even though this drill is made in China, the price does not reflect this. This drill is expensive.
Additional Specs
| Weight | 5.5 pounds |
| Number of batteries | 1 |
| Dimensions | 3.25 x 11.8 x 8.17″ |
| BPM | 4,900 |
| RPM | 1,400 |
| Warranty | 5-year limited |
2. DeWALT 20V Max SDS Rotary Hammer Drill
This DeWALT hammer drill is, like the Milwaukee, an SDS hammer drill. And DeWALT is another great American brand.
This model from DeWALT has 1,100 RPM and creates 4,600 beats per minute.
Moreover, this also has vibration control to make the drilling process smoother and less of a workout, and the brushless motor extends the runtime of the battery.
Why We Love It
Great Brand
DeWALT is a worldwide success story. The company has a history that stretches back to the early 20th century, and it has grown into one of the biggest manufacturers of power tools in the world.
Ergonomic Design
The design and power to weight ratio make this an ideal drill for overhead work. It also has a vibration-reducing feature to decrease hand and wrist fatigue.
Brushless Motor
The brushless motor requires less maintenance when compared to brushed varieties. It also means the power gets distributed more efficiently, increasing the runtime of the battery.
Keep In Mind
Separate Battery and Charger
To sell the battery and charger separately is a bit cynical of DeWALT. It means you double your purchase costs, and their batteries are not cheap.
Price
This drill is very expensive as a bare tool, let alone when you factor in the cost of the battery and charger.
Additional Specs
| Weight | 6.4 pounds |
| Number of batteries | 0 |
| Dimensions | 13 x 4.2 x 8.6″ |
| BPM | 4,600 |
| RPM | 1,100 |
| Warranty | 3-year limited |
3. Makita XRH01Z LXT Rotary Hammer Drill
This Makita rotary hammer drill packs a real punch. The RPM is lower than the DeWALT, but that’s not an issue when drilling through concrete. It creates 4,700 BPM, 100 BPM more than the DeWALT.
The brushless motor increases the runtime of the battery by 50 percent, so you get optimal use out of each charge. This drill has 3 settings, rotary, hammer drill and hammer only, so the toughest concrete doesn’t stand a chance.
Why We Love It
Power Management
The batteries have three protective management systems. You have overload, over-discharge and overheat protection.
Longer Runtime
The runtime is increased thanks to the brushless motor. It is more efficient, requires minimal maintenance and allows you to work for prolonged periods because the motor stays cool.
HEPA Vacuum Attachment
Okay, so the vacuum attachment costs extra, but it means that this drill is entirely safe to use and removes any dust particles that would otherwise get inhaled.
Keep In Mind
Separate Batteries
As with the DeWALT model, this Makita comes with no batteries or charger. Buying them separately is fine if the bare tool is priced competitively, but this drill is already expensive. When you add in the cost of the extras, it makes this drill very costly.
Additional Specs
| Weight | 7 pounds |
| Number of batteries | 0 |
| Dimensions | 4 x 10 x 5″ |
| BPM | 4,700 |
| RPM | 950 |
| Warranty | 3-year |

24-Position Clutch
Choosing the right torque setting stops your drill motor and gears from becoming damaged under too much pressure.
All-Metal Gears
How the power is delivered depends on the quality of the parts inside the drill. All-metal gears have the strength to withstand harsh treatment to prolong the life of your drill.
Keep In Mind
Key Chuck
While it may only be a minor complaint, having a chuck that needs a key, you will have to bear in mind it will take longer to change drill bits.
Trigger Lag
When you depress the trigger, there is a slight delay before the drill motor engages. This is more of an annoyance than a complaint.
Additional Specs
| Weight | 6.62 pounds |
| Number of batteries | 1 |
| Dimensions | 7.56 x 2.85 x 8.19″ |
| BPM | 3,150 |
| RPM | 2,000 |

Nitro-Carburized Chuck
The metal chuck gives it superior strength, and the carbide inserts improve the grip.
Keep In Mind
No Battery or Charger
Yet again, we have a battery-operated drill being sold without a battery or charger. It’s a bit like buying a car and paying extra for a steering wheel or engine. We just don’t get this policy.
Expensive Batteries
Selling the battery separately means that DeWALT makes the drill look cheaper than the rivals while doubling the costs of the model. Clever!
Additional Specs
| Weight | 4 pounds |
| Number of batteries | 0 |
| Dimensions | 4 x 10 x 8″ |
| BPM | 38,250 |
| RPM | 2,250 |

How to Determine the Horsepower of Cordless Hammer Drills?
Horsepower is the description of the relationship between speed and torque. Horsepower can be misleading because manufacturers frequently measure the peak power, which is the maximum the drill produces before stalling.
It shows the drill at maximum output, and if you were to run your tool like that, it wouldn’t last a week before burning out.
Horsepower is also affected by the efficiency factor, and the quality of the tool determines this. An efficient motor might deliver 93 percent of the power thanks to better quality parts and a more durable gear system.
Cheaper models with the same horsepower may only deliver 70 percent because standards have dropped in the quality of the manufacturing.
Which Hammer Drill Voltage Should I Choose?
Most cordless hammer drills are advertised as either 18V or 20V. So deciding which to choose can be confusing. There is no difference between 18V and 20V. They are the same. It would come down to the cost between models and the torque the motor can supply with its available voltage.
For example, you may get a hammer drill with an 18V battery but it produces a higher torque and is considerably cheaper than a similar 20V hammer drill. It makes sense to then opt for the 18V hammer drill.
What we do know is if you are choosing a hammer drill, don’t consider anything below 18V unless you are using it for lighter tasks. As we said earlier, voltage is the way we measure the power of the drill.
The Cordless Drill Future
Cordless drills used to have a reputation for being weak and only suitable for lightweight tasks. Not any more. Battery technology and advances with brushless motors have improved the battery-operated drill beyond recognition.
Nowadays, they easily perform as well, and in some cases, better than their corded rivals.
