When the neighbors make repairs, the first thing that is heard most loudly is the work of the puncher. But if you decide to install a suspended ceiling in your room or change the situation of an ordinary apartment in a studio, you understand that this is the most indispensable tool. Thanks to the puncher, you can quickly make holes in the brick, concrete and stone. A small nozzle is obtained by drilling and creating fasteners. Large peaks can quickly disassemble the partitions and redo the layout in both the bathrooms and all the apartments.
Other models of punchers are used for road repairs or in industry. But this tool has many features that it is important to know in order to properly perform the work and not to spoil the wall. Incorrect model selection can even create an emergency situation under certain conditions. Therefore, knowledge of key parameters and features will help to make a competent choice for any needs.

The best perforator manufacturers - which company to choose
European and Asian companies have been competing for a long time in the production of qualitybuilding tools.
If you understand all possible differences and parameters simply do not have time, and you need a quality perforator for permanent operation, you can purchase a model of any of the following manufacturers:
1. Makita
2. Bosch
3. DeWolt
4. Bort
5. "Interskol"
But due to the wide range of characteristics of this tool it is advisable to familiarize yourself with specific models of these companies in the ranking of the best perforators in order to be sure of the suitability of the device for certain types of work. For those who wish to figure out everything in their own right, this article is devoted to a detailed examination of the device and the criteria for its selection.
Principle of operation and the device of the perforator
The perforator is fundamentally different from the impact drill by its break-through function. The key action of this tool is precisely a powerful blow to the wall, which does not depend on the force of the user pressing. Drills are designed primarily for rotation, and the shock function consists in a slight tapping on the drill mechanical part.
The main load in the drill is created only by pressing force. Therefore, it is possible to work with a puncher even for people with little physical preparation, since it is necessary to direct and hold it for carrying out tasks without additional actions.
Thanks to the powerful chiselling, the punch is capable of punching holes both for creating subsequent fasteners and for destroying a part of the wall for various needs:
- creating ventilation units;
- making holes for doors and windows;
- dismantling of partitions for access to pipes;
- wall slashing under wiring and communication.
To perform these operations, the punch has special internal elements. In most models there is an electric motor, to which the voltage is transmitted through the brushes. The current causes the armature to rotate and transmit the torque further to the "drunk" bearing.
The latter received its name due to the moving part during torsion. A drill is inserted into the chuck with a winning nozzle or a peak, and the electric motor starts the rotation. The bearing clings a piston, which accelerates and hits the ram. The force is transferred to the side, which leads to rapid penetration of the holes.
In addition to the key assembly in the puncher, there is a chuck for fixing a drill or a spade and a main handle with a start button. Most models are provided with a snap lock, so as not to waste effort on keeping it in the long run. The second handle helps to take and more accurately guide the tool. To change the modes, variorok is provided. The switch sets the mode of action on the surface: rotation, impact and rotation, or only impact.
To determine the depth of breakdown on most models, there is a plastic ruler attached to the body, resting against the wall, it shows how much the drill penetrated into the dense material.
In the case of a jamming of a drill in the wall, a clutch is provided that disconnects the nozzle and the rotational mechanism. This helps avoid knocking the instrument out of your hands and preserves the integrity of the internal components. To continue the work, the reverse is started and the drill is extracted.
Types of perforators
Despite the general purpose, the perforators have several types, which determines their functionality and scope of use. Understanding these differences will narrow the tool selection area.
Network punchers
Thanks to the constant connection to the power supply, such models have high power and high performance. They are widely used in repair work and electrified construction sites. With their help, it is easy to shroud the walls and make openings in the partitions.
Advantages:
- has three modes of operation;
- affordable price;
- are equipped with additional functions( depth stop, comfortable grips, snap locks);
- high performance;
- adjustable speed;
- body design with anti-vibration inserts;
- practical cases for easy transportation.
Disadvantages:
- movement is limited by the length of the cord;
- with frequent use weakens the strength of the fixation of the drill, and the cartridge has to be changed;
- performance decreases with a general voltage drop.
Cordless perforators
This type of tool refers to domestic and is designed for short use in places where there is no electricity. With the help of a battery puncher, it is possible to make several holes in the wall to securely fasten the hanging structure or create an opening for ventilation. But for long works it is not good. Advantages:
- due to independence from electricity there are no restrictions at the place of use( garage, house in the forest, cottage);
- high power for stand-alone device;
- presence of reverse;
- light weight;
- drilling of concrete with a hole diameter of 10 mm;
- compact body;
- convenient transportation;
- speed regulation.
Disadvantages:
- the duration of operation is limited by the capacity of the battery;
- fall from height is fraught with the failure of the battery;
- is not suitable for frequent use;
- is difficult to buy a battery separately.
Pneumatic hammers
This tool has in its device an electric motor, which is driven by a stream of compressed air from the compressor. Further the process continues as in the network models, but the impact force is formed by the pneumatic supply of the piston by pressure. These guns are used in factories where there is a centralized air network( compressed air pipes) to save electricity, or in specific conditions where sparks from a voltage can lead to an explosion( mine).
Pluses:
- a large number of beats per minute;
- drilling of bricks, concrete, metal;
- soft hose can be long and does not restrict movement;
- two operating modes;
- light weight;
- availability of depth control;
- auxiliary handle;
- is easily detached from the hose;
- simple transportation;
- high speed.
Disadvantages:
- to start working, it is necessary to wait for accumulation of pressure in the compressor capacity;
- high cost;
- can only be used where there is an air network or compressor.
Gasoline perforators
This category of tools is used in the initial stages of construction and reconstruction, when you need a great destructive power( removing walls, old foundation).The devices are completely independent of current and air, and can be operated throughout the day. They differ in high impact force. The second area of application is road repair.
Advantages:
- possibility to work from one refueling for about two hours;
- presence of three modes;
- hit a great deal of power;
- no wires interfering with movement;
- tool can be operated in any location( without electricity, remote structure).
Disadvantages:
- high cost;
- larger sizes;
- additional gasoline costs;
- a strong blow can lead to unnecessary cracks;
- need to take a canister with fuel;
- heavy weight;
- no impact force adjustment.
punch selection parameters To find the optimal device and not to overpay for excessive power, but also not to break the machine after 6 months from excessive loads, it is important to know the key parameters of the punch selection. Here are the most basic.
Impact strength
This criterion is responsible for the force with which the drill or peak will be immersed in the material, and is measured in J( joules).The impact strength is one of the three components of the tool's performance. Since it is not the pressure of the worker on the handle, but the indicator of the apparatus that plays a big role here, it is necessary to purchase models with 4-12 J.
for professional repair work, where a lot of holes are to be made per day in a brick and stone. If only periodic use is planned forpersonal needs( to make an opening, to create nodes for fixing under the djupelya), then it will be enough for 1-2 J. During frequent work with a thick layer of concrete, models with 27 J will be useful.
The impact rate
The second component of productivity is expressedin the frequency of the strokes that the piston makes about the firing. Even with a large force of jerks, but a small number of beats, the work will be slow, so the frequency indicator is very important for professional activity regardless of the hardness of the wall material. To fully work on repairs and construction it is worth buying models with parameters of 5000-6000 beats per minute. For home use, an apparatus with a number of 3000-4000 bpm is suitable.
Power and shaft speed
The third component of performance is the rotational speed of the chuck. Although the first two parameters described above correspond to the drilling depth, the rotation of the drill facilitates the sampling and removal of the crumbled material and the speed of drilling of the thick elements. To a puncher can quickly make turns, you need a powerful electric motor. For drilling thick walls, you need to buy a tool with an output of 700-1200 W and a speed of 2300-2500 rpm. If the task is to drill the fasteners no deeper than 40 mm, then 400-500 W and 1000-1200 rpm are sufficient.
But here it is worth considering the diameter of the drill. If you plan to work with small drills 5-8 mm in diameter, then you can use high speeds( 1500-2500 rpm).When drilling wide holes, a thick drill bit at a fast speed will wear out and it will have to be changed more often, so here it will take small turns( 600-1000 rpm).
Type of chuck attachment and drill diameter
This parameter is indicated by several letters and can say nothing to the inexperienced buyer. But, not having understood, it is difficult to get the right product.
There are three categories of cartridges:
1. SDS +
Refers to amateur versions that are universally suitable for most drilling and fixing points. They are able to clamp a drill with a diameter of up to 25 mm in concrete or 30 mm in wood. Such a puncher is good to have in the country or in the garage.
2. SDS max
Represents a professional niche of cartridges that fix drills of large sizes and punch openings up to 52 mm. This is convenient for the rapid creation of openings and wide shtrobleniya. Suitable builders and repair teams with full employment.
3. SDS top
This is the narrower direction of cartridges for drilling in the range from 16 to 25 mm. If you need holes of this diameter and others are not foreseen, then you can confidently acquire such an option. It is best to use them for drilling the fixing points of suspended ceilings.
Having bought a puncher with a certain cartridge, it may turn out that a large-diameter drill is not included in it or small burrs slip out. Therefore, it is worthwhile to think carefully about the majority of work with the tool and determine the optimal type of clamping device.
Number of
modes Single-mode guns do not exist, otherwise it would be a conventional drill. Dual-mode models can work on rotation and rotation with impact. Vibrational movements contribute to the penetration of the drill and the rapid passage of material through and through. The third mode allows you to stop the rotation and work only with the longitudinal impact function.
The more modes, the more expensive the tool, so the three-mode models should be purchased with a variety of activities( drilling, hole creation for fasteners, through drilling, shunting for pipes and wiring).If the puncher is needed in order to drill into a concrete wall, then a two-mode construction is sufficient.
Weight and shape
The perforator has to work in different spatial positions, so the weight and shape of the device directly affect the convenience and fatigue. Models with a horizontal engine arrangement are lighter( 2-3 kg), which makes them optimal for ceiling work or manipulation on outstretched arms.
Apparatus with a vertical motor is heavier( 4-6 kg), but more compact and balanced for holding with both hands and drilling the walls. T-shaped models are most suitable for work in the lower position( drilling floor, asphalt) and have the heaviest weight( 7-9 kg).
Power source capacity for standalone versions of
When choosing stand-alone models on batteries, the battery capacity plays a big role. This parameter determines the time when the device is used without a network. For rare use, to drill a few dozen holes, it is enough 1.5-2 A / h. If you have to work hard without the possibility of recharging, it is worth buying a model 3-4 A / h.
In the case of the petrol version, the capacity of the fuel tank is responsible for the autonomy. The volume of 0.9 liters is enough for two hours of work without interruptions. But if you take a can of gasoline, then the capacity of the barrel ceases to play a big role.
Additional parameters of the
There are small additional elements in the hammers to facilitate the use of the tool:
- If the exact depth of drilling is of fundamental importance, then the model with a stopper is useful;
- With the priority of work only by impact, retention of the perforator will be facilitated by the anti-vibration system;
- Soft start-up relieves overheating and prolongs the life of the device;
- The reverse will quickly remove the jammed drill bit at great depth;
- Adjusting the rotation speed will give greater freedom in the drill diameters used.
Which perforator to choose
In view of the parameters described above it is possible to classify all the perforators in groups for a specific activity:
1. For professional builders and repair crews with full employment, a network puncher with impact force of 6-10 J, 1000 W and 2500 rpm,min. The cartridge is worth looking for SDS max. The device must have three operating modes.
2. In the case of an auxiliary network tool for the home master, the impact force is 2-3 J and the power is 500 W.The number of revolutions will depend on the type of drills used: 1,500-2,000 rpm for fasteners, and 600-800 rpm for thick drilling. The cartridge is in most cases SDS +.The number of modes depends on the needs of the owner: the drilling of concrete walls will require a two-mode tool, and strobing will prove effective on the three-mode model.
3. When working in the field, the battery-powered puncher with a capacity of 4 A / h and a cartridge SDS + are useful. For large-scale works it is better to buy a gasoline engine with a vertical engine arrangement.
4. If there is an air line next to it, then the air perforator will save money. It is especially important to use it in a mine or other gassed space with increased explosiveness. The cartridge and the impact force should be selected based on the use of the tool, as in the cases described above.
How much does the perforator
? Summing up the various groups of the instrument, it is possible to single out its approximate cost for specific tasks:
1. Professional powerful network models with high impact force and high frequency will cost 25 000-27 000 rub.
2. For domestic use, the cost range of electric punchers is 1800-5000 rub.
3. Rechargeable versions are worth 3500-4500 rub.
4. Gasoline models in view of high power cost from 25 000 to 65 000 rub.
5. Pneumatic equipment will cost 47 000 - 94 000 rubles, depending on the shape of the hull and the impact force.
