Demolition Hammers Buying Guide:
How to choose the right product from the demolition hammers test or comparison above.
- A demolition hammer is used when the simple hammer drill fails. There are lightweight caulking hammers in this category for chiseling up walls and heavy demolition or demolition hammers for tearing up floors.
- When buying a demolition hammer, you should pay attention to the impact force. For solid reinforced concrete, it should be at least 23 joules. If you just want to get a hole in a wall, 6 – 8 joules is often quite enough.
- If you buy a cheap demolition hammer, you should pay special attention to the weight. Some models weigh more than 20 kg. To keep them in operation requires a lot of strength.
There are always walls that need to fall because they are in the way and are just a relic of the past. This may be the elaborate brick wall of natural stone at the sitting area of the garden. In times of open or American kitchens, it can also involve the wall from the kitchen to the living room, so that the American lifestyle also arrives in your own DIY paradise. Of course, to match the new eat-in kitchen, the floor certainly needs to be done so that everything really matches. But until the renovation is done, a lot of time passes and a lot of energy must be spent. If the hammer, chisel, angle grinder and cordless hammer drill are already lying battered in the corner, a bigger toy is needed to help the walls learn to fall. In this case, the bright do-it-yourselfer looks for an electric demolition hammer or an electric caulking hammer.
In our demolition hammer comparison 2021 guide, we not only want to present you with a demolition hammer comparison winner, but also show you how to find the best demolition hammer for your purposes through a little buying advice.
What is a demolition hammer?
The demolition hammer is sometimes also called a chisel hammer, caulking hammer, demolition hammer, breaker or as a demolition hammer. This tool can be powered electrically, pneumatically or by an internal combustion engine (using gasoline). It is a percussion hammer for breaking up or tearing down foundations, ceilings and walls made of concrete, stone or brick. Certainly the best known version is the so-called pneumatic hammer or air hammer, which is used in road construction.
Unlike a drill or impact drill, the tool does not rotate. The screed concrete or stone is slowly worn down by blows via a chisel. Due to the high weight of sometimes more than 10 kg, demolition hammers are usually used only in vertical working direction. However, there is also the smaller caulking hammer, which finds application when breakthroughs are to be made in walls.
Fun brakes will certainly mention that there is already a hammer drill and chisel for such work in the DIY sector. Certainly, the hammer drill may likewise be used for demolition work. Since the hammer drill also has a percussion mechanism, a chisel can be clamped relatively quickly, so that a wall can also be removed from tiles. However, the power of the hammer drill is much lower than the demolition hammer. Therefore, such a hammer has significantly more problems with screed concrete, natural stone or hard bricks, and even a DIYer in this case will have to resort to a larger chisel hammer.
The advantages and disadvantages of a demolition hammer at a glance
- very high impact force
- easy penetration into steel-concrete
- different chisels for different projects
- high weight – not all can be used in horizontal position
- partly high purchase price
- very high impact force (over 20 joules) for working on concrete, natural stone and bricks
- easy demolition of floors, terrace slabs and foundations
- equipped with flat chisel and pointed chisel for many tasks
- very high weight – not recommended for horizontal work.
The classic demolition or demolition hammer is mainly used vertically to work on the ground. It can be used to clear a concrete foundation relatively easily. Even the terrace slabs in the garden do not pose a problem. On walls, the machine should be used only after a few visits to the gym, otherwise the weight in operation can hardly be held.
- very high number of blows – for the processing of bricks, tile adhesive and partly also concrete
- lower weight – also suitable for chiselling walls and ceilings
- pointed chisel allows easy and precise work
- less impact force – penetration into concrete therefore sometimes problematic
If you just want to chisel a hole in the wall and a core drill won’t help you, you should reach for a caulking hammer. These chisel hammers are much smaller and lighter. This type of construction allows them to be applied precisely and can even be used to cut tiles in the sanitary area.
Buying criteria: What distinguishes a good demolition hammer?
In the electric hammer sector, Scheppach, Mafell, Bosch, Hilti and Hitachi are certainly well-known brands. Still, you may wonder what each model and series is good for. Is a Bosch hammer better than a Scheppach demolition hammer? Should I buy a caulking hammer from Bosch or Makita? Or does it only depend on the chisel for the demolition hammer? With our small buying guide, we would like to bring you closer to the most important points, for the choice of the best demolition hammer.
Whether Duss demolition hammer or Wacker caulking hammer: Unlike a hydraulic hammer or a demolition hammer for excavators, the power plays a special role. Is an electric caulking hammer with higher power better than a device with lower wattage? Actually, no, because the input power only indicates how much current the professional demolition hammer can absorb. Certainly, you can draw conclusions about the hammer’s work performance based on its power, but comparing actual work values is more appropriate. Nevertheless, the demolition hammer from 1600 watts is mostly used in DIY.
Tip: The slogan “more power” may be passed on by many DIYers, but it usually only says something about the power consumption and not how efficiently the motor works.
Number of blows and impact force
Whether demolition hammer Einhell or demolition hammer Scheppach offers, you should pay a little attention to the technical values. The impact force is specified in joules. For classic demolition hammers, it is over 20 joules. For small caulking hammers, it is only 8 joules. This means that a demolition hammer strikes twice as hard as a caulking hammer. This also makes it much easier to cut through the concrete. However, with the caulking hammer, much more precise work can be carried out (e.g. removing tiles or chiseling up a wall) due to the lower force when striking.
Normally, when it comes to accessories in a demolition hammer guide, you would certainly expect to find drill bits or oil and grease. But whether you buy a caulking hammer used or rent a demolition hammer after all, you’ll find that it’s all a matter of finding the right chisel. There are pointed chisels for big jobs like penetrating concrete and flat chisels for loosening tile. Not all manufacturers offer the full scope of delivery, so when buying a Hilti TE 3000 AVR demolition hammer, you should also pay attention to whether a chisel is really included in the scope of delivery, so that the work can begin immediately.
The additional handle was included in the scope of delivery of all models in our comparison and is also bitterly necessary if the heavy device is to penetrate the wall or floor really firmly and precisely. So that you can also safely store all the individual parts, you should pay attention to a tool case, so that you do not have to buy an empty tool case later.
If the demolition hammer is electrically operated, the weight is certainly not as crucial as with the compressed air demolition hammer. Nevertheless, even an electric Metabo or Toolson demolition hammer with more than 20 kg, can be relatively heavy. You should therefore look for a lightweight model, which brings less than 20 kg on the scale. Cheap demolition hammers are usually rather heavier here, while a brand-name device from Bosch or Makita can weigh just over 10 kg.
