A hammer drill is a multifunctional tool that drills, drives screws, and bores holes into hard materials, including stone, brick, metal, and others. Hammer drills are frequently used in residential settings to bore holes in walls so that pipes or cables can be run inside from the outside.

A hammer drill is a durable, adaptable, and powerful instrument thanks to its large size, optional auxiliary handle, and many settings. The best hammer drill can be a wise addition to your toolkit because it can function as a conventional drill, an impact driver, and a compact jackhammer. Continue reading for more details on picking the best hammer drill from some of the greatest corded and cordless drill producers.

1. Hammer Drill vs Drill: What’s The Difference?

When browsing the hardware store for new cordless drills, you come across similar models. The sole distinction between the two is that one is referred to as a hammer drill or, more precisely, a hammer drill driver. A close review of the differences between a drill and a hammer drill reveals that these two tools have many similarities. Except for the internal hammering system, they are all similar.

Physical Differences Between a Hammer Drill and a Drill

To make the hammer drill, most manufacturers start with a drill driver and then add a hammer mechanism behind the chuck. Usually, it adds a few millimeters to the overall length and a few ounces to the weight. When you compare the two side by side, it could be difficult to see the difference between them.

Both clutch settings and drill settings are available on modern hammer drills. There is a second hammer mode that you can select when you look at a hammer drill.

While some kinds maintain them all on the same collar, others separate the clutch collar from the mode changes. Regardless, the hammer and drill modes are always next to one other. Even on hammer drills with electronic settings, the clutch, modes, and gearbox are mechanical switches and collars on the head.

The hammer mechanism introduces a chipping action similar to a rotating hammer. In the largest hammer drills, that motion occurs more than 30,000 times each minute!

Performance Consequences of Hammer Drill vs Drill

You should activate the hammer mechanism when drilling a hole in concrete or masonry. With it, drilling can proceed effectively. Hammer drills typically operate 25% faster than standard drills in our tests.

In our Milwaukee M18 Fuel hammer drill, we recently conducted a test utilizing a 1/4-inch multipurpose bit. It took roughly 8.5 seconds to drill to our target depth in regular drill mode. It took around 6.5 seconds to switch it into hammer drill mode.

Losing 2 seconds might seem like a little. However, it has a substantial influence when you use larger bits or need to drill several holes.

When you drill in hammer mode, you'll also hear a noticeable difference in sound. The hammer mechanism makes a quick buzzing sound in addition to the bit sound.

When drilling through wood, metal, plastic, or any other material, you should never use the hammer mode. In some materials, the chipping motion doesn't facilitate faster drilling. It can sometimes slow you down and make the experience very vibrating.

2. What to Take Into Account When Selecting the Best Hammer Drill

For your upcoming job, it's crucial to consider several critical elements when choosing a strong hammer drill. Selecting a device with a variable speed trigger will provide you better control after determining whether you prefer a corded or battery-powered option. The various modes of operation are the next thing to consider because even a standard drill will frequently feature a variable speed trigger. The top hammer drills may be used for screw driving, drilling through softer materials (like wood), and hammer drilling into masonry. Make sure you have the appropriate drill bits for the task, though.

Corded versus Cordless

A heavy-duty wire or a rechargeable battery can power hammer drills. Despite their cumbersomeness, many construction professionals still prefer corded hammer drills because they offer more consistent power and torque than battery-operated models. When working on a busy job site, it is important to have a dependable and efficient tool. Corded hammer drills typically have more power than battery-operated ones, making them ideal for long days on the job. However, they are bound to a nearby power source by an extension cord, which can be cumbersome.

A corded hammer drill would likely lose power after several hours of operation, but these models have some benefits. They are often lighter, smaller, and easier to move than their corded counterparts (plus, there is no risk of tripping over the annoying power cable). Since cordless gadgets are more portable and versatile, DIYers are more inclined to favor them for home renovation projects.

Hammer Mode

All hammer drills have a setting called "hammer mode," which is frequently identified by a hammer. This setting introduces pulsing action to help masonry bits cut through tough materials like brick, stone, and concrete.

In addition to having more hammering power, the drill still has the rotational power to drill and punch through tough materials, which is akin to using a jackhammer and a drill together, albeit to a lesser extent. Long durations of difficult jackhammering through stone, brick, and mortar are designed specifically for rotary hammer drills.

Drill Mode

On hammer drills, a button is often used to toggle between the hammer mode and regular operation. "Drill mode" is the term used to describe this. Only a variable-speed setting between 1 and 3 can be used to distinguish it.

Alternatively, depending on the model, it might be identified by a symbol that looks like a drill bit. This model is designed to drill holes through softer materials, including wood or plastic, and has more controllable torque.

3. The Best Hammer Drill - FAQs

The best hammer drill is the one that best suits your needs. There're many things to consider when getting the best hammer drill, such as the type of material you will be drilling, the size of the hole you need to drill, and the speed at which you need to drill. Do some research to find the drill that best suits your needs.

Size Differences Between Milwaukee Hammer Drills and DeWalt Hammer Drills?

The Milwaukee hammer drill is also much more compact than the DeWalt model—it is about an inch shorter! The two are nearly the same weight. With an XC5.0 Ah battery loaded, the 2806-20 hammer drill only weighs 4.8 pounds. With a 5Ah battery, the DeWalt DCD997 barely surpasses that weight by a few ounces.

My Hammer Drill Won't Cut Through Concrete; Why?

Concrete is dense and hard and contains embedded aggregate stones that may present barriers to the drill bit, making it challenging. Drill bits can get quickly dull during drilling. The bit pulls significantly more when it comes into contact with aggregate.

Is a Hammer Drill Necessary for a Homeowner?

You can more easily drill into concrete or masonry using a hammer drill's mode, which produces a downward hit on the drill bit. Even though it doesn't seem like a woodworking tool, most homeowners and woodworkers will eventually wish to add one to their toolkits.

What Distinguishes a Hammer Drill from an SDS Hammer Drill?

What distinguishes a hammer drill from an SDS hammer drill? SDS hammer drills are a subset of hammer drills. On the other hand, SDS hammer drills are more potent than regular hammer drills, making them ideal for heavier-duty drilling tasks.


In conclusion, a hammer drill is a great tool for a variety of projects. It is easy to use and can drill through a variety of materials. It is also relatively inexpensive. The best hammer drill is the best option if you are looking for a drill to help with your next project.
