Top 20 best demolition hammers: rating 2021-2022 models for concrete
A jackhammer is a professional construction tool, although it has only one function. chiseling. Because of such limited functionality, demolition hammers are rarely bought for home use, but on a construction site you can not do without it.
When buying a jackhammer first of all determine the scope of its application. In some cases it is not necessary to buy an expensive model, because for chiselling not very hard materials also budget devices will do.

- relatively low emissions;
- gasoline consumption 0.9 l/h;
- reduced vibration at 3.8 m/s².
Which demolition hammer to choose
To get the job done right and on time, you need to choose a quality tool that has good technical indicators, as well as reliability.
Excessively strong device will consume too much energy, as well as more expensive to maintain, to say nothing of the high cost of spare parts. A tool that is too weak will simply fail to cope with the work. For this reason, the device should be chosen solely for certain purposes.
Let’s look at the types of criteria for choosing a demolition hammer. The width, length, and height are no doubt important parameters of the tool itself, but the weight is also important. Longer structure means more strength, but sometimes it is silly to chase after strength, because the compactness of the device is the best choice when it comes to solving the apartment problem.

The weight can also play a cruel joke, it would seem that a heavier device will have a greater force, but if there is a breakage of the walls or ceiling, the entire load will come exclusively on the hands and back of the person. For this kind of work, the best choice would be a lightweight tool with a high number of blows per second.
The next criterion is the frequency of impact. It can be measured in hertz or rpm. The first is the number of strokes per second. The second is about the speed of translational motion.
Another important attribute is the energy of a single blow. In other words, it denotes the productivity of the energy expended per blow. This indicator is measured in joules, one unit of which is equal to 100 grams.
The drive, as we have already said, can be different. For apartment repair an electric demolition hammer is perfect, and for plumbing work it is possible to take a pneumatic hammer. In the field is usually used gasoline, hydraulic. in industrial facilities. Power tells how much energy is consumed in a certain amount of time. It is measured in watts.
Also when choosing one should pay attention to such indicators as vibration and sound pressure levels. It is not unreasonable to ask about the dimensions and types of shank.
If an electric tool is used, then it is mandatory to match the voltage of the device and the home network, which is expressed in terms of energy consumption. Also any device can have additional elements and functions.
Types of demolition hammers
The construction site is not complicated by rules: the more powerful the tool, the faster the work is done. However, if we consider a demolition hammer, its choice is based not only on the weight of the device and the impact force, but also on the peculiarities of mechanics and energy source. The tools are divided into three weight categories.
Best Hammer Drill Cheap Rotary Impactor & Chisel for Tile Quick Set Demolition Home Projects Review
- Lightweight, with a mass of 5-6 kg. Such a tool is recommended for use where freedom of action is needed (in cramped conditions, when working at an angle, at points of convergence of walls, and so on). A lightweight demolition hammer is used when working at height.
- The medium class tool (5-10 kg) shows the best results when working in vertical, horizontal direction.
- A heavy demolition hammer (up to 30 kg) is great for working with soil, foundations.
Regardless of its class, the tool comes with a standard set of picks. The nozzle can have different sizes. The kit includes a pick-lock for ripping or breaking, a spatula for chipping and edge leveling operations, and a chisel for chipping or chopping material. Depending on site conditions, you can choose the type of tool that shows the greatest level of comfort and safety.
The electric demolition hammer shows the best results in finishing work, when removing old coatings. However, this tool also has disadvantages:
- cannot be used in rooms with a high level of fire and explosion hazard due to sparking of the rotor brushes;
- Can malfunction or show motor malfunction in high humidity.
the electric tool is always dependent on a power source. Therefore, it does not make sense to choose a demolition breaker of this class for construction work in buildings without 220 or 380 V mains.
A cordless electric hammer is useful where there is no mains power. However, devices of this class can not show an acceptable operating time, are characterized by reduced impact energy. In addition, the battery power significantly increases the weight of the tool. The use of a cordless demolition hammer is rational only for one-time, emergency work.
- Has a slightly heavier weight than an electric hammer
- not tied to power distribution points, fully autonomous;
- Can show a significant level of impact energy, especially with the use of reducers.
However, gasoline-powered machines have a fairly significant list of disadvantages.
- Fume, toxic gases do not allow to work in confined spaces.
- There is a constant risk of fuel spillage and ignition.
- Significant noise level.
Working with a gasoline hammer is convenient in the open air. Such a tool. a good and economical choice if you need to remove asphalt, pierce sleepers, make landings under a pile foundation.
Pneumatic hammer, depending on the power, can be of two types:
- with impulse transmission by expanding the air inside the piston chamber;
- operating on volumetric expansion, by feeding air into the diaphragm chamber with a rod.
Regardless of the operating principle, the pneumatic tool has a key feature: it requires additional equipment. A minimum set. an air compressor. It can be supplemented with strapping elements that increase the continuous operation time and provide other advantages. The compressor tool has the following advantages
- Has the lowest weight in comparison with other types of demolition hammers;
- Compressor tools are completely fire and explosion proof;
- in some cases, you can save a lot of money if you use homemade receiver and other elements of compressor piping;
- the noise at work is minimally achievable because the blower, in most cases, is in the distance.
The main disadvantage of pneumatic tools is the need for a compressor, the source of power for it. However, with a large-scale application of demolition hammers of this type, this disadvantage is compensated by convenience. By organizing the air central, to which several units of tools are attached, it is easy to organize the comfortable work of a group of operators with a single unit.
Please note! A hydraulic demolition hammer has similar features. However, such device has a disadvantage when working body (usually oil) because of possible leakage, due to violation of sealing or damage of the hose. And this is an additional source of fire danger.
The way from a pickaxe to a jackhammer
When stone caves were man’s predominant habitation, it was then that the first signs of using devices to facilitate the working of hard rock appeared. It was most likely stone chisels and axes.
For tens of thousands of years, nothing has changed fundamentally in this area of human activity. Just as the blocks for building the pyramids were chiseled by hand in ancient times, the techniques for breaking stone, extracting coal and salt remained at the same level as the hand pickaxe until the end of the 19th century.
The invention of electric and internal combustion engines revolutionized this activity. The ease of converting the rotary motion into translational motion, with periodic action on the pick, has led to mechanical demolition hammers, without which neither road construction, nor mining, nor rescue operations after an earthquake can be imagined.
Types of demolition hammers according to the principle of operation
To be more exact, the principle of operation of all demolition hammers is the same. A solid metal hammer is set in motion inside the tool. Having gained some acceleration, it strikes the rear side of the working tool, the spade. And though this peak is practically motionless the impact energy transfer occurs along it to the working tip and from it to the material surface to be treated (constructions, soil, covering etc).п.) Applying force repeatedly in one point within a short period of time produces the desired result. destruction (crumbling, splitting, crushing) of the processed material.
And here the principle of imparting reciprocating movements to the striker may be different and use absolutely dissimilar sources of energy. So, according to this criterion, demolition hammers are divided into electric, working on their own internal combustion engine (gasoline), pneumatic. There are also hydraulic, but they still refer to the specific equipment, in the construction industry almost never used.
It is interesting that electric demolition hammers were the first to appear. of course, very far from being perfect. The development of pneumatic models. this, in some ways, was a forced measure. The fact is that the use of electromechanisms with their sparking brushes led to explosion- or fire-hazardous situations in mines, where the air can have a high concentration of flammable gases or fine coal dust.
The flowering of electric tools took place much later. in the second half of the XX century.
Nevertheless, let’s begin examining it with the pneumatic, as the most simple in its construction.
Pneumatic demolition hammers
Very briefly, in general outline let’s consider the scheme and principle of operation of a pneumatic demolition hammer
The entire mechanism is assembled in a robust hammer housing (pos. 1). The working handle is fastened at the top (pos. 2), by means of which the operator guides the tool. Here, in the upper part, there is also a nozzle (pos

з. 3) for connection of the flexible hose of compressed air from the compressor.
At the bottom there is a cartridge (pos. 4) into which the appropriate working rod for the task in hand is inserted (pos. 5).
The compressed air is fed to the demolition hammer from the working compressor continuously. But in the tool itself there is usually a “no-load” mode, when no shock forces are created. no air is sucked into the system of internal channels and valves of the hammer. The starting mode can be activated by pressing the starting button (lever) located on the handle. But more often the principle realized in the above scheme is used.
Please note. in the sectional drawing the valve is shown in pink (pos. 9) which is pushed upward by the compressed air in idle mode. It blocks the channel of air infiltration further into the hammer mechanism. But when the craftsman presses the rod into the material to be worked and then presses the handle down with his hands or his body weight, the valve is opened and the air starts to flow into the hammer mechanism.
The actuating cylinder (pos. 6), along which the massive hammer piston moves up and down (pos. 7). The body itself has a system of interconnected air passages and valves that ensure the cyclic operation of the device.
With some simplification, it looks as follows: when going into the operating mode, an overpressure zone is created in the upper part of the main cylinder by compressed air. Underneath the piston, on the contrary, there is a vacuum at this time. The piston rod pushes downward, gains kinetic energy, and then hits with force the back of the mounted spade (pos. 8). The blow, as we have already said, is transmitted through it to the object to be treated.
At the same time the air channels are switched, i.e. there is an overpressure under the piston and a vacuum above it. The piston moves upward, and in doing so causes the air ducts to “recombine” again. That is, the whole “history” repeats. the pressure grows from above, the piston-blade tends downwards until the strike. and so on.
It takes quite a long time to write about it, and in fact, the frequency of blows of a pneumatic demolition hammer can go up to 25 ÷ 30 blows per second! This concentration of force in one point is exactly what gives the desired result.
What’s good about pneumatic hammers??
- Simple design. nothing superfluous and hence. high maintainability. Most frequently repairs are connected with replacement of worn seals or other parts of the valve mechanism.
- Absence of built-in drive is also low weight of the tool itself, i.e. it is more convenient to work with it.
- Sparks are eliminated, and such tools are allowed to work in areas with a high concentration of gas or dust. they will not cause a fire. High humidity or even precipitation can not hinder the work.
Their disadvantages are as follows:
- Clinging to a compressor that in turn requires a power supply. Almost literally, tied down, since the working radius is limited by the length of the air hose.
- The tool is very demanding to the stability of the air pressure created by the compressor and therefore usually is not limited to the compressor. you also need a roomy air receiver.
- It takes a lot of time to prepare a jackhammer for work.
- Possible problems with operation in cold weather. The expansion of air at the exhaust from the tool is always accompanied by a sharp drop in temperature, and the demolition hammer can begin to “freeze”. its channels and valves become clogged with ice and lose their normal conductivity. This is especially true if the relative humidity is high and the compressor doesn’t have a drying system of supplied air.
- Working with compressed air always involves a certain level of danger and requires special precautions.
Tool selection criteria
When choosing this type of tool, some users may encounter the problem of a wide range of. The following criteria should be taken into account when choosing a tool:
- Speed per minute. allowing you to control the speed of your work. Powerful devices allow you to destroy different types of surfaces in a short time.
- The power of the tool. the power of the tool affects the type of material to be broken. Small tools are most often used for interior finishing work. With a high power tools are designed for demolition of concrete and rock.
- the weight of the tool. the comfort of your work depends on the weight. Heavy tools are not easy to carry or use in the horizontal position. Therefore, when choosing a model, you need to consider the scope of use. The most optimal weight for the device is 7-12 kg.
- Variety of hammer chucks. the level of professional device depends on this criterion. SDS Plus chucks are used for lightweight models. For heavier devices you should give preference to models with SDS Max chucks, which are used for long-term operation.
- Availability of anti-vibration system. a necessary system for increased comfort during operation.
- storage case. a special device that allows you to easily move the hammer over long distances. The carrying case has all the necessary compartments for storing the accessories.
- The work indicator. the user has the ability to select the desired mode on their own during operation.
When choosing a demolition hammer also matters the company that manufactures the product. Some unknown manufacturers give their users a quality build and a guarantee of long life. That is why it is important to read the reviews of real users before buying. When buying a tool you should also consider the availability of additional attachments. Different saws are used for durable materials. You must also pay attention to the availability of the handle, which is used to control the speed of the tool.
The rating of the best demolition hammers in 2022 allows you to make the right choice and buy a hammer with the necessary functionality at an affordable price.
