Which Jackhammer To Choose

How to choose a jackhammer: 6 tips Which jackhammer should you choose? Features of pneumatic and electrical models. What to look for when buying a bump stop?

Impact attachments

The device allows you to change the nozzle for specific work. As a rule, attachments are included, but you can purchase them separately. Most popular tips:

• Pick-crowbar. It is with this sharpened detail that the bump stop is most familiar to see. Such a nozzle is used for dismantling concrete, brick, stone, destruction of asphalt. It can also be used in non-standard situations, for example, to loosen the soil for its subsequent processing.
• Scapula. Suitable for removing tiles from walls or floors, removing old plaster from the surface. The nozzle really looks like a small shovel, at the end it has a significant extension with a straight cut. The edge is sharpened and very sharp.
• Chisel. This building element is needed to cut the reinforcement, destroy the frozen ground, make a hole or a niche in the wall. It is also used when working with metal structures during their dismantling.

The ramming attachment is also suitable for the hammer. Its mission is clear from the name. To compact the soil (it is also possible with stones), to close up faults in hard-to-reach places, and more.

Ahead behind the bump stop: nuances, tips

All bumpers are divided into 2 types:

1. Pneumatic. Most often it is used for complex construction and installation operations, in mines. An outlet is not required for work. The bump stop quietly performs its functions in high humidity, is not afraid of fire and explosions. The tool is intended purely for industrial professional use, not in everyday life. The exception is small hammer drills that function as a bump stop. An example is TOPEX 74L331. A compressor station is needed for smooth operation.

2. Electric. In such a bump stop vibration is felt least of all; special skills are not required to use it. Powered by an outlet. Most popular on the market. The segment includes both household models and professional-grade devices. There is also a minus: not suitable for objects with high levels of humidity.

There are also gasoline ones, but they are rarely bought. It is necessary to focus on the power indicator (from an outlet or without it) depending on the category of work performed. So, the electric bump stop is universal, it can crush concrete in two planes, however, it is worth considering the placement of the motor.

For horizontal tasks, a tool with a vertical motor is needed, and vice versa. Hammers with a horizontal motor are the most compact, weighing up to 10 kg. These household mechanisms will not cope with complex and large-scale construction work. For roads and large construction sites, only a vertical concrete breaker is chosen.

The list of essential parameters required when choosing the best jackhammer (electric or other type) also includes:

3 best electric jackhammers

• Makita HM1203C. Medium power bump stop. The chuck allows you to set the chisel in 12 positions, adjusting the angle of work. There are 5 modes of beat frequency, you can choose a suitable variation in the range of 950-1900 beats / minute. The model is equipped with protection against motor overload, the possibility of a soft start and a stabilization system to maintain the working pace during prolonged use.
• Bosch GSH 16-30. The tool of true professionals, daily production. Up to 13 tons of filmed material. It has a vibration damping system that not only relieves stress from the hands, but also extends the life of the bumper. The body of the device is made of metal parts, durable, not afraid of falls. The tool will remain unharmed even if a wall falls on it.
• Sparky K 615CE HD. This bump stop is equipped with electronics to record the force of the impact under any load. The comfort of work is provided by an anti-vibration system, smooth start, the ability to independently adjust the force of impact. To protect against overloads, there is an LED on the case, which signals overheating and possible malfunctions.

Noteworthy fenders with power supply are also produced by the companies Dnipro-M, Kawasaki, Stanley, Hilti, Zenit.

Impact strength

The greater the force of the blow, the more the hammer will be able to beat off in one blow. This indicator is related to the volume of work performed, because the speed of work depends on the strength of the blow. Force is measured in joules and is directly proportional to engine power.

The lightest jackhammers are capable of delivering up to 20 J, the average impact force ranges from 20 to 40 J, and the heavy and powerful jackhammers work with a force of 40 J and more.

Impact attachments

Demolition hammers are capable of working with various types of attachments. They come with many instrument models, but you can always purchase the missing one separately. The most popular types of attachments:

• Pick-scrap. It has a pointed end, like a usual scrap. It is used for demolition work (destruction) with hard materials. Concrete, stone, brick, asphalt.
• Scapula. Ideal for removing tiles or finishing materials from surfaces. The blade must be well sharpened to be effective.
• Chisel. This nozzle can destroy reinforcement, frozen ground, and create holes. The chisel is very useful when working with metal structures.
• Pick-tamper. It is used for soil compaction, sealing joints and cracks.

Power

By power, jackhammers can be divided into the following subcategories:

• 900 to 1300 watts. A tool with this power rating can dismantle walls made of brick, stone or concrete.
• Over 1300 watts. Demolition hammers with the highest power are suitable for professional work. Demolishing asphalt, concrete, frozen soil, demolishing walls and even foundations.

The weight of a jackhammer depends on its power and capabilities. The lightweight tool will be easy to transport, you will be less tired when working, but it will not be able to complete all tasks. A heavy tool can handle anything, but it takes a lot of work.

• Lightweight jackhammers weigh from 6 to 10 kg. They are convenient to use for work at height and inside houses.
• Average weight ranges from 10 to 20 kg. With their help, you can create openings in the walls, destroy partitions, etc.
• Heavy jackhammers (over 20 kg) are not very suitable for domestic work and are often used in professional activities, for dismantling monolithic structures, working with large volumes of concrete, granite, etc.

Which jackhammer to choose

In order for the work to be done correctly and on time, it is necessary to choose a quality tool that has good technical performance, as well as reliability.

An overly strong device will consume too much energy, and it will also be more expensive to maintain, let alone the high cost of spare parts. A tool that is too weak will simply not do the job. For this reason, the device should be selected exclusively for specific purposes.

Let us examine the types of criteria for choosing a jackhammer. Undoubtedly important parameters of the tool itself, namely width, length and height, weight is also important. A longer structure speaks of greater strength, but sometimes it turns out to be foolish to chase after strength, since in solving the housing issue, the compactness of the device will be the best choice.

Weight can also play a cruel joke, it would seem that a heavier device will have more strength, but if a wall or ceiling is to be broken, then the entire load will come exclusively on the person’s arms and back. For this type of work, the best choice would be a light tool with high impact rates per second.

Another important sign is the energy of one blow. In other words, it means the productivity of the energy that was spent on one hit. 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. An electric jackhammer is perfect for repairs in an apartment, and pneumatics can be used for locksmith work. In the field, gasoline is usually used, hydraulics. At industrial facilities. Power refers to how much energy is consumed in a given time. Measured in watts.

Also, when choosing, you should pay attention to indicators such as vibration levels and sound pressure. It will not be superfluous to inquire about the sizes and types of shank.

If an electric tool is used, then it is imperative that the voltage of the device and the home network match, which is expressed in the consumed energy. Also, any device may have additional elements and functions.

What is it and how does it work

The tool is percussion in principle, capable of splitting hard rocks, concrete slabs, as well as asphalt pavements. Management takes place at the expense of a person who controls the device manually. The impact force, frequency, and duration of action are controlled.

The tool is considered mechanized, but the drive is of several types: electric, hydraulic, gasoline and pneumatic. The speed of work varies from 15 to 50 strokes per second.

Which jackhammer to choose

Until recently, the jackhammer was only used in the mining industry. However, with the development of new technologies, this tool has moved into other areas. Now it is used on every construction site where the corresponding work is required. With its help, complex tasks can be simplified, and the work itself with a jackhammer does not cause any particular difficulties. In this article, we will take a closer look at this device and give examples of a good choice.

How best to choose a jackhammer, which is better

To do this, we will briefly consider several of the types presented. Pneumatic operates on the pressure difference between the sides of the rotating piston. It is pneumatic that is used to create openings and windows in brick, concrete or plaster walls, because the engine itself seems to be small.

Petrol. This is the heaviest option of all the types presented. Inside it is an internal combustion engine that is not large in volume, the force of impact of which everyone will envy. The bump stop can be used to break concrete, asphalt and sleepers effortlessly.

Hydraulic can operate on various power sources and even under extreme conditions. Under water. It is used by rescuers in emergency situations. It differs from all others in its high endurance when breaking down very hard rocks.

And finally, the last representative is electric jackhammer. As we already understood from the title of the article, it operates on a network of both 220 volts and 380 volts. Its main advantage is that it is characterized by low levels of noise and vibration. The power of each device can range from 500 watts to 2 kW. The companies Makita, Bosch, Hitachi and Interskol have especially proven themselves in the market.

Do not forget about the safety of working with this tool. When working, you should wear safety glasses, because debris can get into the eyes and injure the cornea, a respirator that can protect the lungs from dust. In modern jackhammers, the safety of the owner is far from the last place: a system is constantly working that predicts the proximity of the cable or the possibility of its breaking.

Comparison of Makita and Bosch demolition hammers

Probably, not everyone knows the history of the Makita jackhammer, but each of us had the opportunity to observe how workers make “holes” in the asphalt, doing repairs. Initially, the chipper was used only in the mining industry for the extraction of ore and stone, but today it is used in almost all stages of construction and repair.

So, let’s dwell on what this device is, what types it is, its distinctive features, and also which is better to choose a jackhammer, Makita or Bosch?

This bump stop is based on the action of a percussion mechanism, and is intended for chiselling and breaking walls, asphalt, concrete, masonry, concrete floors, for making furrows in ceilings and walls, chiselling technical holes and much more. Basically, some of the important indicators when choosing are factors such as:

• Power to weight ratio;
• The strength or magnitude of the impact;
• Power from 0.6 to 2-3 kW;
• Automation of idle and working stroke;
• Seat type (keyless chucks for quick nozzle change and hex chucks to keep the firing pin securely on the tool);
• The ability to leave the switch in the working position;
• Dust protection that will prolong the operation of the device;
• Vibration damping system for comfortable work.

At the base of the jackhammer is a chisel, chisel, or lance, and they are made of hard metals and alloys. The principle of operation is based on the supply of pulses of low frequency (16-25 Hz), as a result of which the reciprocating movements destroy the material. The fundamental difference from rock drills is that jackhammers do not have the ability to drill a hole in parallel. The cost can range from 7 thousand to 60 thousand rubles and depends on the destination.

Which manufacturer is better than Makita or Bosch?

Makita was founded back in 1915 in Japan. And we all know that if it is made in Japan, then it is made for centuries. It is thanks to the quality of the products that the company has become a leader in the development and production of this apparatus. The range of hammers can impress even the pickiest customer.

The Precision Mechanics Workshop was founded in 1886 by Robert Bosch in Stuttgart. This can be considered the year of foundation of Bosch, which was the first to invent the jackhammer and is known all over the world today. From the very beginning, Bosch has been characterized by innovative management and social responsibility. During this time, these companies have established themselves very well in the market not only for household appliances, but also for construction tools.

Consider their technical characteristics:

• The power consumption is the same as that of the Makita jackhammer and that of Bosch (within 1450-1500 watts);
• The cartridge type is the same. Sds MAX;
• The impact force of the Japanese apparatus is 21.9 J, in contrast to its opponent;
• The number of strokes is the same: from 900 to 1900 beats / min;
• Weight Makita hm1202c 9.3 kg, and the weight Bosch GSH 11E. 10.1 kg.

Now you know everything about the tools presented, their main technical characteristics, the approximate cost in the market, but which one to choose and which one to buy is up to you.

And if the equipment is needed for one or two times. Think about whether it is worth spending a lot of money on buying a new one. You can rent our device and make your dreams come true.
