Top 2 Best Hammer Drills on The Market:

DeWalt DCK299P2 20V MAX XR Lithium Ion Brushless Premium Hammer Drill & Impact Driver Combo Kit


No one would like the idea of buying many tools to complete a single DIY project. A single tool with several attachments comes in handy and works well for most projects. However, that may not be the case for professionals.

Mostly, power drills do not deliver enough speed or torque for constant heavy-duty projects. A cordless drill might stall out before you get your bolts or screws fastened fully. Moreover, when that happens, you will not feel confident about the completion of your project.

If you work as a professional carpenter, plumber, or HVAC repairer, you would not like to risk such reduced performance. Therefore, for any project that requires drilling and driving reliably, you will need two different tools. The DeWalt DCK299P2 is a good option. It offers excellent battery life, power, and two beautiful tools to help you complete your jobs efficiently.

Its design and lithium-ion battery makes its handling more comfortable. The power output is excellent, and you should expect around 1,825 in-lbs. That is more than enough for most commercial and regular home jobs. The combo includes a hammer drill, which provides 2,000 RPM.

DeWalt DCD996B Bare Tool 20V Max XR Brushless 3-Speed Hammer Drill Review


Power tools are a significant investment and if you want to own equipment that will last for many years; you should go for quality products. Apart from having a top-notch design and construction, such a tool will help you complete your projects smoothly. Thankfully, most people have been relying on DeWalt products for a long time.

Both amateurs and professionals highly appreciate the products, including the DCD996B Bare Tool. Due to its unique power and versatility, you will efficiently complete all your DIY projects. Even though the market has many other similar tools to offer, DeWalt DCD996B brings more value.

The product has a higher power output (820 units-watts out) and 3-speed settings, and it can tackle a broader range of applications. Its speed levels start at 0-450 rpm (the highest torque setting), 0-1,300 rpm (offers mid torque speed), and end at 0-2000 rpm.

The manufacturer also provides a different speed reversible feature, which allows operation in forward, reverse, and variable speeds. For safe usage, the reverse and forward control button work as the lock-off button to prevent accidental switch-on. The unit comes with a brake to stop operations immediately after the user sets the trigger switch off.

Advantages of Impact Wrench

Most individuals believe that impact wrenches are only usable in construction and industrial sites. However, you can use them at your home to fasten bolts or nuts for various tightening or loosening purposes. Impact drivers are great tools both professionally and domestically, and some people refer to them as torque guns, rattle guns, air guns, or air wrenches.

Manufacturers are offering several types of impact wrenches, but hydraulic and electric models are very new to the market. The wrenches provide accurate torque, and most of them are easy to use. Contrary to the traditional versions, they do not kick back.

Advantages of Impact Driver

Impact drivers are more popular due to their unique design. Due to their thin design, they are a good alternative for any individual working in the construction or automotive industry. They are neither regular drivers/drills nor hammer drills.

Their appearance is distinct with little profile and hex attachments. The devices are more responsible for work, and their impact actions switch on naturally when a need arises.

Advantages of Hammer Drill

Standardized hammer drills drill into light metal, drywall, wood, brick, and concrete. They precisely remove and drive long and standard screws without pilot holes. They allow the use of large drill bits when drilling large holes. Moreover, even though they are more substantial than other types of cordless drills, they are easier to handle.

When drilling, the adjustable clutch will automatically increase the torque if the resistance increases. That means that you will never put more pressure behind your drill than necessary, which is the case to expect with standardized cordless drills. While using this tool, you will only need to apply more weight if the hammer drill uses a lower voltage.

You will require particular drill bits for the hammer setting. When in this setting, a drill bit plugs in and out when spinning. Generally, hammer drills will help you complete numerous projects.

Can You Use An Impact Wrench As A Drill?

Yes. You can use an impact wrench to drill holes, but that will highly depend on the level of accuracy you need. For a rugged construction, including boring holes to pass some wires through, you can use an impact wrench. However, if you require accurate placements – the roundness and size are vital – stick to regular drills and drill bits. In fact, the market only offers bits with ¼” hex shank.

Are Impact Drivers And Impact Wrenches The Same?

Before impact drivers became popular, most DIY people had two primary options when power wrenching – the standard electric drills and the torque wrench. The electric drill was a good go for when completing general-purpose driving, fastening, and drilling.

Typically, use of the powerful impact wrenches was high in the restoration and automotive repair industry.

After the introduction of impact drivers, most people started going for them. Apart from their sleek and compact design, impact drivers provide more torque than standard drills and are more convenient than the considerable impact wrenches.

Generally, impact wrenches are bulky, heavy, and more potent than impact drivers. They use a square drive (1/2″), and manufacturers make them for fastening and loosening sockets while impact drivers use ¼” a hex drive. Manufacturers make impact drivers for use when driving screws.

You can quickly change an impact driver into a ½” square driver by using an adaptor bit. After that, you will be able to use it with various socket drivers.

Moreover, unless you are trying to renovate a semi-truck, impact wrenches provide much power that you do not need in your around-the-house projects. Impact drivers are suitable where standard drills cannot offer adequate torque, but impact wrenches are beyond general-purpose uses, such as drilling holes and driving screws.

The two, impact drivers and impact wrenches, function in a similar way. They use concussive rotational blows to deliver maximum torque. They do not spin as the standard drills do.


Q: What is the difference between impact drivers and cordless drills?

A: Cordless drills/drivers are the most popular because they can accept driver bits or drill bits of any size. Drills have only one type of operation – smooth rotational action.

Impact drivers on the other hand provide swift rotational actions. They also provide higher torque by delivering thousands of impacts per minute on internal mechanisms. The operation is noisy but allows the low-recoil way that can help you drive fasteners with high torque than drills.

Q: When should I use an impact driver?

A: You can use an impact driver to fasten any fastener. Screws – no matter the type – are the most popular types of cables. However, impact drivers can drive lag bolts of any size, nuts, and anything that requires turning. With a socket attachment, you will easily drive eyebolts or l-hooks.

A drill will put much strain on your wrist as you provide counter forces to the rotation when driving long screws into hardwood. Screwing the head is easy when working with an impact driver. Hammering action in the machines makes rotational force, and the user has little recoil to deal with while in use. You will complete your projects within a short time regardless of the type of wood you are using.

Q: What is a brushless impact driver/drill?

A: “Brushless” denotes the motor or engine powering the impact driver. Standard motors have brushes, which pass electricity to the spinning rotor. The brushes are known to wear out within a short period and therefore affect the performance of a machine.

However, brushless motors do not require spinning parts to function. That alone reduces heat and friction and increases the durability of the tool.

Q: What are the differences between 20-volt and 18-volt drivers, 10.8-volt and 12-volt?

A: Most manufacturers choose the 20-volt terminology as a way of marketing their brand. After recharging a battery fully, it will have a higher voltage rating than while it is working. Most of the brands that label their tools as 20-volt also include a disclaimer claiming that it is the Peak or Max, voltage – the operating voltage is usually lower.

Again, that does not mean that you can use your 18-volt battery with a machine labeled 20-volt. Most manufacturers use different battery form-factor, formats and electronics to market their products.

Q: Can I use an impact driver to drill holes?

A: Yes. Impact drivers have higher RPMs – cordless drivers have more top speed than cordless drills. Some impact drivers do not have good control of low-end speed, and you will, therefore, have problems starting holes.

The high torque means that the machine chews more massive holes from the auger or spade bits with lesser effort. If you do not want to purchase an entire set of hex-shafted drill bits that can match the typical ¼” chuck, most manufacturers provide drill chuck attachments.


We cannot cover every possible usage situation of hammer drills, impact drivers, and impact wrenches. The only thing we can do is provide a general recommendation. If you are a DIY’er, maker or woodworker, go for a combo kit.

Almost every manufacturer produces combo kits containing an impact driver and a regular drill. An impact wrench is suitable for heavy-duty projects.
