The rotary hammer drill: The best tool in the history of tools!
The rotary hammer drill is the absolute must-have tool in every home and workshop. It can drill holes into any know material - from wood, to brick and even concrete. Whether you simply want to hang a picture on the wall, or firmly dowel an entire kitchen: without a rotary hammer drill, you won't get far - as a simple drill is liable to stop working when it comes to brick walls.
We'll admit that at Einhell there are a lot of tools we consider to be irreplaceable. And most of them are. But every well-equipped workshop - whether for DIYers or professionals- absolutely needs a few basic tools. And the one tool that everyone really needs is a rotary hammer drill. Why? Quite simply, it's a real all-rounder, and can take a lot on with just a few simple functions.
The rotary hammer drill drills holes - that much is obvious. Holes in wood. Holes in brick walls. Holes in drywall construction. Holes in reinforced concrete. But it also chisels and caulks. It is the perfect tool for working both the rough and the smooth!
While most small drills and impact drills encounter problems at least when it comes to hard materials such as concrete or solid brick walls, the rotary hammer drill is only just warming up. Thanks to its powerful hammer function, a pneumatic hammer drill or an electric hammer drill can work its way effortlessly through all conceivable materials. Wherever you want to drill a hole in the house, with a rotary hammer drill from Einhell you will always have an easy job. In the third part of this article, we will take a closer look at the possible applications of the device.
The rotary hammer drill: Here are the basic functions
To give you all the information you need to choose the right model, this comparison will first tell you how the rotary hammer drill works, what features are available and what you should look out for when purchasing one.
Drilling, caulking, chiselling- with these three basic functions the Einhell rotary hammer drill starts just where your drill stops. The pneumatic impact mechanism allows the machine to work quickly and effortlessly through masonry, stone and even concrete. Let's take a closer look:
Drilling with the rotary hammer drill
Just like a drill, but with much, much more power. That's the simplest way to describe a rotary hammer drill. The rotary hammer drill owes its incomparable power to its electropneumatically driven impact mechanism. A powerful electric motor generates the powerful impact movement by initiating a stroke movement with a rotational movement via the drive bearing and a piston. This throws the hammer towards the drill head, which pushes forwards with a swing. This impact movement ensures the necessary propulsion of the drill used, which almost automatically drives the hole into the wall.
Although the concept is similar to that of an impact drill, a pneumatic hammer drill is much more efficient and powerful. Due to the precision working, filigree and precise holes are also possible despite the power.
Caulking and chiselling with the rotary hammer drill
Even though the rotary hammer drill is used for drilling holes most of the time, you mustn't forget its second function. The drill's impact force described above is perfect for caulking and chiselling work. Whether it's tapping tiles in the bathroom or removing a complete wall: the rotary hammer drill gets to work at full power here.
To use the caulking function, all you need is a suitable chisel with standardised SDS mounting and a small press on the device itself. The rotation movement necessary for drilling can be completely deactivated using a switch on the device. This turns the hammer drill into a light caulking hammer, which drives the chisel tip into the material to be caulked with great force. You can get the corresponding SDS chisels for the hammer drill from specialist retailers. They are available in different lengths and with different tips for maximum power and precision. We'll explain more about the SDS system in the following!
The Einhell rotary hammer drill: maximum power and maximum flexibility
Whether you're looking for a demolition hammer, electric hammer drill or cordless hammer drill: at Einhell you will find a huge selection of different models for your specific requirements. These heavy-duty are designed to be uncompromisingly when it comes to power and perform with brute force even in tough demolition jobs.
On the other side of the scale are our handy cordless rotary hammer drills, which combine maximum freedom of movement with good performance.
In terms of performance and handling, our electric rotary hammer drills fall exactly between these two categories. They offer high power reserves in a compact housing and are well suited for all requirements. Let's take a closer look at the differences between them in comparison.
If it's gotta go, it's gotta go! The Einhell demolition hammer
Uncompromising. If we had to describe our demolition hammer with just one word, that would be it. Hardly any other machine in our range converts electricity into pure power in such an unfiltered way. With up to 50 Joules you can demolish concrete slabs, foundation walls and stone with the demolition hammer and ensure clear conditions on the construction site. The demolition hammers come without a rotating function and convert the entire motor power into drive propulsion. The 33 mm SDS-MAX system and the solid chisels are ideal for putting that power exactly where it belongs!
Speaking of chisels... With our rotary hammer drills you have the choice between working with chisels with or without a fixing. The advantage of the flexible alternative is clearly mobility: The device can be rotated at the top and remains fixed at the bottom of the chisel in its initial position.

Guide, don't push: This ensures that you will drill a clean hole with the rotary hammer drill
Although these devices are heavy and powerful, when using a rotary hammer drill, a sensitive touch is required. Important: Always position the machine straight and keep the angle to the wall or ceiling constant. Even if a little play in the SDS holder is forgiving of small mistakes, you should make sure that you work as evenly as possible.
The pressure of the rotary hammer drill into the wall should also be even. And even more importantly: You should only guide the device gently into the hold. The rotary hammer drill will do practically all of the drilling work itself. The more you push, the less space the hammer has to swing and gain momentum. So, less really is more here.
As a rule, you should pay attention to your safety before drilling or chiselling:
- Are the cables securely connected?
- Is my conductor stable?
- Do I have the necessary safety equipment (hearing protection, safety goggles, etc.)?
The answer to these questions should always be "yes" before you start any work.
Summary: You can find the right Einhell rotary hammer drill for every job
As you can see, a rotary hammer drill is one of the most universal power tools, and is loved by DIYers at home and professionals alike. When choosing the right tool, you should carefully check your requirements: What masonry is going to be worked on? How strong is the concrete?

Whatever your requirements, you'll be able to find the right device for you. As an all-rounder with cordless battery operation, we would recommend the HEROCCO. The RT-RH 32 is a class stronger, but with a mains connection. With both devices you are perfectly equipped for everyday jobs!
