What is a hammer drill and what is it used for?

A hammer drill is an electric tool that combines the functions of an impact hammer and a drill. It is used to drill holes in hard building materials, such as concrete, brick and stone.

The hammer drill is a powerful and versatile power tool that works well wherever it is necessary to drill in resistant and hardest materials, such as concrete, stone or brick. The basis of the hammer drill's functionality is the impact mechanism, which generates strong vibrations - the resulting percussion and impact energy allows it to easily break through the surfaces of the workpiece, making the tool indispensable for construction work. In addition to drilling holes, the hammer drill can also be used for lighter forging, which is useful when chipping tiles, forging grooves in walls or preparing surfaces for installations and other light repair work.

This tool is particularly useful in places where a traditional drill would be insufficient due to a lack of impact or less power. The hammer drill's multifunctionality is its key advantage - some models offer a non-impact mode for drilling in wood or metal, as well as a rotary mode for mixing mortar or glue.

What is the difference between a hammer drill and an impact hammer?

A rotary hammer drill and a demolition hammer are tools designed to work with hard materials, but they differ in design, function and range of applications. A hammer drill is more versatile - it combines the function of a drill and a hammer, so it works well for drilling in concrete, brick or stone, as well as for light forging, such as tile chipping. With the option of drilling with impact and drilling without impact, the hammer drill is relatively versatile and can also be used in less demanding materials, such as wood or metal.

A hammer drill is a tool with much higher percussive power, designed mainly for heavy-duty work such as wall demolition, concrete chipping and other demolition work. Unlike a hammer drill, an impact hammer does not have a rotary drilling function, so it is not used for drilling holes, but only for forging and breaking. Thanks to a special mechanism, the impact energy generates powerful vibrations that allow it to smash even very hard materials, making it a specialized and invaluable tool for demolition work.

Cordless or corded hammer drill?

The choice between a cordless hammer drill and a corded hammer drill depends on the type of work to be done and where it is to be done. Both types of tools have their advantages and limitations.

Advantages of cordless hammer drills

Cordless hammer drills are ideal for those who value mobility and convenience. With battery power, you can move freely in the field, even in places without access to an electrical outlet. Modern lithium-ion batteries offer long working time and fast charging, making them an excellent choice for small jobs around the house and in the garden.

Advantages of corded hammer drills

Corded hammer drills have more power, making them a better choice for intensive construction and renovation work. Thanks to the constant power supply, you don't have to worry about running out of battery, which is crucial for long-term projects. In addition, they tend to be lighter, making them more comfortable to use.

When to choose a cordless and when to choose a corded one?

A cordless hammer drill will be a better choice if you plan to work in the field or in hard-to-reach places. A corded hammer drill, on the other hand, will work well for tasks that require a lot of power, such as intensive drilling in hard materials. Choose cordless hammer drills for convenience and mobility, and network hammers for heavier construction work.

What to look for when buying a hammer drill?

A good hammer drill tailored to your needs is a key step to ensure comfort and efficiency of work. Here is a list of the most important parameters to consider when choosing and buying a hammer drill tailored to the task.

Device power

The power of a rotary hammer is one of the most important factors affecting its performance. Typically measured in watts (W) or volts (V), it is based on the electric motor of a rotary hammer. More power allows you to drill faster and easier in hard materials such as concrete or stone. When choosing a rotary hammer, it is worth paying attention to devices with a minimum power of 800 W, which ensures good performance in most standard construction works.

Impact frequency

The impact frequency, measured in beats per minute (bpm), tells you how often a rotary hammer generates during operation. Higher impact frequencies (e.g. above bpm) allow for efficient drilling in hard materials. However, it is worth remembering that the optimal value depends on the type of work performed – lower values are enough for lighter tasks.

Single Impact Power (Impact Energy)

The power of a single impact (impact energy), measured in joules (J), determines the force of the hammer drill hitting the material. Higher impact power allows for more effective action. For construction work, it is a good idea to look for hammer drills that offer an impact energy of 2 J, which will ensure efficiency in demanding tasks.

Max. totation speed

Maximum RPM, measured in revolutions per minute (rpm), is important when you plan to drill in a variety of materials. A higher speed (e.g. above rpm) is beneficial for drilling in wood or metals, while a lower speed with hammer function is better for drilling in hard materials. It is worth choosing a model with speed control, which will allow you to adapt it to specific tasks.

Vibration level during chiseling and drilling

Vibration is an important factor affecting the comfort of work. Rotary hammers with lower vibration levels (e.g. less than 10 m/s²) will be more comfortable to use, which will reduce hand fatigue, especially during prolonged work. It is worth investing in a model equipped with a vibration reduction system, which will increase comfort and safety during work.

Weight

The weight of the hammer drill affects its mobility and comfort of use. Lighter models (about 2-3 kg) are more handy and comfortable to use, which is important during long-term work. On the other hand, heavier models (over 3 kg) usually offer more power and durability, but may be less comfortable in longer use. It is important to choose a hammer drill that will be suitable for the type of work and comfortable to use.

SDS max and SDS plus chuck

Choose a rotary hammer with an SDS max or SDS plus chuck, which allow you to easily change accessories without the need for additional tightening. The SDS chuck type allows for quick drill bit changes and ensures their stability during operation, increasing precision and safety. 

Other features

It is also worth paying attention to additional functions that make it easier to use the tool and increase safety - the ability to change the direction of rotation, various operating modes, overload clutch (motor overload limiter), vibration reduction function, start mitigation systems, chisel position setting, LED illuminating the work area or ergonomic handles. Particularly noteworthy is the vibration reduction function, which is useful in very powerful machines. When choosing a rotary hammer, also check the availability of accessories and the warranty, which may indicate the quality and durability of the device.

Which rotary hammer to choose?

Choosing the right hammer drill should be adapted to the nature of the work being carried out. Different requirements are placed on a tool intended for domestic use and different requirements for equipment used in professional construction applications. Here are the most important parameters to pay attention to when choosing a rotary hammer and make a good decision.

Which hammer drill for home use?

For home DIYers and people who need a hammer drill for occasional work around the house, it is recommended to choose cordless models or less demanding corded hammer drills with a power of 600 to 800 W. Such devices should offer a hammer function, which will make the work easier. It is also good for the equipment to be light and handy, which will make it easier to work in hard-to-reach places. Models with variable speed and interchangeable SDS drills will be more versatile and will allow for a variety of applications, from drilling holes to chiseling.

Which rotary hammer for professional use?

For demanding users - construction teams and professional contractors - the best hammer drill is the one with higher power (over 800 W) and high impact energy (ud min 2 J). These devices should be equipped with features adapted to intensive use, under heavy loads, such as powerful motors, vibration reduction systems and the ability to operate in different modes. It is also a good idea to invest in models with SDS Max chuck, which provide quick drill bit changes and greater stability during operation. Rotary hammers for professional use must be durable, reliable and able to work in harsh environments, also prepared for longer tool life.
