Regular drills are not powerful enough for heavy-duty works, that’s why you need a hammer drill. Unlike cordless drills (which only spins), hammer drills spins & hammers simultaneously making it possible to dig deeper.
What about cordless drills that do hammering function?
You might have seen a cordless hammer drill. However, trust me, Cordless hammer drills don’t have that much power as corded ones. You will end up draining batteries while doing heavy-duty tasks like drilling and shattering concretes or bricks.
As per the survey conducted by the U.S. Bureau of Labour Statistics, 2017, most of the fatal accidents are caused in construction and building maintenance areas, which poses a high risk to the labour force. So, you need to choose tools that provide maximum safety. Stay away from cheap hammer drill brands.

Hammer Drill Buying Guide
With heavy competition among the manufacturers and compelling features to become a hit among the customers, more and more high-end features are being incorporated. But first, you need to look for the critical features of the hammer drills. Remember, some drills come as bare tool which means you’ve to buy batteries, charger etc. individually.
Power is one major factor for consideration when it comes to buying hammer drills. The hammer drills can be electric, or battery powered. Battery powered drills are portable and are less efficient than cordless drills.
The drills can have a brushed or brushless motor. If you want the drill to be durable, consider a brushless hammer drill. Not to mention, the brushless motor keeps the machine cooler than bushed one.
Torque Power and Speed
The torque of a hammer drill designates the speed and power. In short, If the torque is higher then, it is more powerful. Hammer drills are also measured on the blows per minute (BPM) whereas the drilling speed refers to the RPM.
The chuck size tells about the capacity of the drill. Bigger bits can’t be fit onto small chucks. So, heavy-duty application, which mostly uses bigger bits, needs larger chucks. In short, powerful drills use larger chucks.
Not all tasks need the same speed and torque. Working with single speed drills increases the chance of the screws being damaged. Basically, the multiple transmission speed possibles the hammer drill to work with a wide range of screws and materials. This helps to fine-tune the task. As a matter of fact, multi-speed drills costs higher.
Comfort during operation
Though you might have the best features in the selected hammer drill, one with good handle design, less in weight are most sought out features. Being heavy induces fatigue and makes it difficult to work. Choose the right size of your hammer drill.
Any tool should be easier to handle and comfortably manoeuvrable. It should be capable of performing a range of tasks from the medium, sturdy to heavy-duty tasks. The hammer drill should be able to deliver all your drilling needs. It should be well balanced and be safe to use and apply.
In this consorted list we have listed out the 6 best hammer drill from major players that are suitable in all aspects for your drilling and hammer requirements.
