DeWalt Hammer Drill

DeWalt Hammer Drill

DeWALT Cordless Hammer Drills make quick work of masonry, concrete and other tough material. These versatile tools can do anything from demolition to driving.

These cordless rotary hammer drills generate high impact power that pulverizes your project. For versatility, DeWalt produces 3-mode hammer drills that also give you the same functionality as any of the DeWalt cordless drills/drivers. A 3-mode model lets you work at different tasks without the need for a second or third tool.

Types of Cordless Hammer Drills from DeWalt

DeWalt’s cordless SDS hammer drills use SDS chucks that deliver power directly to the bit, rather than the chuck. This gives you power comparable to a corded model with cordless portability. DeWalt’s cordless rotary hammer drills run on high-capacity lithium-ion batteries that range from 18 to 36-volts. Higher capacity batteries give you longer, more powerful performance, while smaller battery models are lighter and easier to carry for long projects. The 20-volt MAX battery line provides a fantastic run time, and you can use the same battery from your rotary hammer in your other DeWalt cordless drills, saws or similar tools.

Rotary hammers can be hard on your hands and shoulders, so DeWalt developed the SHOCKS™ vibration control system to reduce strain. The 360-degree rotating side handles let you leverage your body weight for exceptional control of your cordless rotary hammer drill. The integrated LED work lights let you see your workspace for greater precision and safe operation at an unlit jobsite. For extra convenience, you can purchase these tools in a kit that comes with a battery and carrying case.

Why Buy DeWalt Cordless Hammer Drills?

DeWalt cordless hammer drills deliver incredible power wherever you need it. DeWalt cordless tools come with a 90-day money-back guarantee, a service contract and a 3-year limited warranty.

What to Consider When Choosing the Best Cordless Hammer Drill

POWER

The more power you have, the quicker you can complete your task. A typical hammer drill motor has about seven amps, while larger motors have about 10 amps. The bigger the motor, the more power it will deliver. However, hammer drill brands with bigger motors will be larger and heavier.

TWO HANDLES

The best hammer drill for concrete and other materials should include safety features for your protection. As a result, most feature two handles. An auxiliary handle provides stability while you operate the drill and also makes the action more comfortable. The side handle should be ergonomic with a comfortable grip. They should also be shock absorbent.

MULTIPLE WORKING MODES

One hallmark of the best hammer drills is multiple working modes, or a selection switch that allows you to choose which mode you’d like to use. Typically, a hammer drill that comes with multiple working modes allows you to choose between rotary drilling and rotary-plus-hammer drilling. This is beneficial because it allows you to use the rotary mode for all of your typical drilling and driving needs. But at the same time, you can always switch over to the hammer functionality if you’re working on masonry. You’ll get more versatility and great on-the-job flexibility, all in one handy drill.

BRUSHLESS MOTOR

You want to make sure your hammer drill is powered by a brushless motor if you opt for a cordless model. A brushless motor is the best kind of power source; it’s efficient, gives you increased power, and works flawlessly with a rechargeable battery. These high-speed motors can increase your hammer drill’s run time by as much as 50 percent per battery charge when you compare them to a typical brushed motor. And that’s an improvement you want to make sure to take advantage of.

Before You Buy a Cordless Hammer Drill

While most of the best hammer drills can pull double duty as standard drill drivers, they’re not for everyone. Even smaller hammer drills will have heavier-duty components inside, which means they are substantially heavier than even the best cordless drill. They also have a lot more torque than light-duty drills, so if you’re new to power tools, don’t be surprised by their power.

If you’re not drilling into concrete, bricks, stone, or masonry, you probably don’t need a cordless hammer drill. You can save a bit of money by going with a standard drill driver for most of your projects. However, if you find yourself mixing concrete or paint often, you might decide that the extra torque hammer drills can offer will help speed up the task.

Our Top Picks:

1. Dewalt DCD999B Cordless Hammer Drill Driver

Dewalt DCD999B Cordless Hammer Drill Driver

Take advantage of more power with the 20V MAX brushless tools with DEWALT FLEXVOLT ADVANTAGE tool technology. This 1/2 in. Cordless Hammer Drill has up to 42% more power when paired with a DCB606 FLEXVOLT Battery vs. a DCB205 20V MAX 5 Ah Battery. Battery and charger sold separately.

Integrated Safety & Electronics Protection Features

First, it is worth noting that this hammer drill doesn’t have an integrated kickback safety feature when in the drill or hammer drill modes. So the risk of sudden torque twists still exists. When drilling through tough surfaces, especially hammer drilling, I am always leery about torque-related risks. (I’ve caught a drill bit too many times on steel or concrete and had a sore wrist for a few days. The DCD999B does feature a variable speed trigger for additional torque control. This means that the more fully you depress the trigger the higher the speed the tool operates at. The responsiveness and sensitivity of the variable speed trigger made it very easy to ramp up the drill speed as required.

Additionally, while all drills will heat up during extended drilling operations (especially hammer drilling), the DCD999B seemed reasonably cool during operation. I wasn’t worried about thermal overload or the battery overheating. The additional power did seem to reduce bit stoppages during operations though. The DEWALT DCD999B hammer drill/driver employs DEWALTS’s industry-standard Electronic Protection System (EPS) which will shut the tool off in cases of potentially dangerous battery overheating or overdraw due to extended usage.

DEWALT DCD999B Ergonomics

The pistol grip is great. It has the same non-slip and formed design I have come to love on my other DEWALT cordless tools. Additionally, I found the checkering, non-slip etching pattern on the keyless chuck to be more comfortable than etching on other chucks I’ve used. And it still maintained a great non-slip grip. The weight was well-balanced when paired with my 6Ah battery. When I used my 2aH battery it was a bit top-heavy but that was expected. When the handle is mounted any slight weight imbalance becomes a non-factor as the dual point hold eliminates this concern. Also, with the auxiliary handle, the extra weight of the larger battery was a positive as it offered more stability and natural pressure when drilling.

Lastly, the location of the speed, mode, and light switches are placed in easy-to-reach locations where I could still single-handedly hold the drill and change any setting required. The switches were a bit stiff. With additional break-in, I’m confident they would slide smoothly yet firmly.

Features:

  • Up to 42% more power when paired with FLEXVOLT batteries
  • Compatible with all DEWALT 20V MAX and FLEXVOLT Batteries
  • GREAT BIT GRIP: Heavy-duty 1/2 in. ratcheting nitro-carburized metal chuck with carbide inserts for superior bit gripping strength

5. Dewalt DCD797 20V Cordless Hammer Drill

Dewalt DCD797 20V Cordless Hammer Drill

We recently conducted our Best Cordless Drill Shootout, where the DeWalt DCD797 20V Max Compact Hammer Drill finished in second place in the Compact Drill and Compact Hammer Drill divisions. Overall, it showed the requisite power, functionality, ergonomics, features, and value to put all but one competitor in the rearview mirror.

Everything that DeWalt is putting out in the drill categories has performed pretty well in our shootout and this model is no exception. The DeWalt DCD797 was the fastest drill in its class under load, and it was no slouch in the torque department either. With a solid feature set that highlights the brand’s Tool Connect capability, this compact model should make fans of the brand happy and give other brands a target to aim for.

PERFORMANCE

So all the bells and whistles are neat, but how does this hammer drill actually perform? As far as speed under load goes, it blazes past every other model we tested with its impressive quickness and efficiency. With a 3/4″ auger bit, we measured the DCD797 turning an average 1,948 RPM.

This is an incredible 98% of its no-load speed. the best efficiency any other model pulled was 80% and most of the drills are in the 60%–75% range. With a 1-1/4″ self-feed bit in low speed, we measured an average speed of 512 RPM from the DCD797. This is 97% of its no-load speed. Once again, no other drill comes close to DeWalt’s speed and efficiency.

We also tested our hammer drills by drilling 3″ deep into concrete using a 1/4″ Bosch Multipurpose bit. The trend continues as the DeWalt DCD797 smoked every other hammer drill in the 18V Compact division. With an average time of 5.92 seconds, this hammer drill beat the next fastest drill to the finish line by more than a full second.

What is a Hammer drill?

Hammer drills fulfill a very specific role, which is to pulverize holes in concrete, brick, marble, granite, and other similar materials. There are mainly two types of hammer drill; the regular hammer drill and the more powerful rotary hammers. Although there is variation between different kinds of hammer drills, generally speaking, they all operate roughly the same.

Inside each hammer drill, a hammering mechanism (the exact mechanism can change depending on the type of hammer drill) essentially “pounds” the drill bit forward. It is this internal mechanism that allows a hammer drill to pulverize its way through concrete and masonry. In terms of what they are meant to do, hammer drills are mean to make holes in tough materials; they can also drive fasteners into the concrete.

Can you use a Dewalt hammer drill as a regular drill?

You can use a hammer drill as a regular drill by selecting the drill mode that disengages the clutch and the hammering action. In this mode, the tool works as a regular power drill or a cordless drill.
