How to choose the right hammer. Drill bit construction
Rating of the best peorators by quality
a peorator is a tool with a percussive mechanism that works on the principle of a jackhammer. With its help pierce holes in different materials, drill and perform dismantling work. In order to understand which peorator to buy, we will talk about the main parameters of choice and present the top peoratorov 2020-2021.
Types of torches by the number of operating modes
The number of operating modes is a decisive factor that determines the performance and efficiency. Depending on the number of modes, all peorators are divided into three groups:
The simplest type of this tool and the least productive. Designed only for drilling relatively soft materials, such as wood, drywall or thin sheet metal.
Includes not only drilling mode, but also drilling with impact. Applicable for harder materials, including concrete and brick. This is the best option for domestic use.
The most productive and common type. Includes drilling mode, drilling with impact and impact mode without rotation, allowing it to be used as a chipping hammer.
When you don’t work with a chainsaw very often, but only occasionally, it doesn’t make sense to buy a powerful tool. For ordinary works, a domestic, medium-powered peorator with an optimal set of functions is quite enough.
A unique tool at a low price (up to 7 000).
The universal tool with a weight of 3 kg. Designed for three modes: drilling, mowing and chiselling. The tool can produce holes up to 24 mm.

The pluses of the RH500 include low weight, low cost and a long enough cord to work away from the power source.
- due to insufficient power, the impact is very modest;
- In continuous operation, the gear begins to heat up and there is a risk of burnout.
How to choose the right geared motor
In order to understand how to choose a peorator for home purposes, it is necessary to follow the recommendations of the masters. If you want to drill in materials like wood or thin metal, you can use a single-mode device.
It is also necessary to carefully study the characteristics of models, and choose the most suitable. It is necessary to give preference to famous brands, with a large number of positive reviews.
Important! When ordering over the Internet, you should study how much the consumables cost for the selected model.
A peorator is the same as an impact drill?
They may look alike, but they are built differently. Peorator and impact drill are used in a variety of applications.
In a drill main working details are 2 gear ratchets, which under constant use quickly wear out, you have to put a new one. When working with it you need to apply great force. The disadvantages include a high degree of recoil and weak amplitude.
The torch has no such disadvantages. It has more power and speed, and lasts longer.
Ease of use and efficiency of power tools for drilling holes is determined not only by the technical characteristics, but also by the presence of additional options. This is especially important for those who plan not just to choose a peorator for home, but to work with it often and for a long time.
Another important aspect, which must be taken into account before choosing a brand or a specific model of peorator is its equipment. The wider it is, the fewer additional accessories you will have to buy later. The quality and compatibility of branded drills, chucks, brushes and other components included in the set are usually significantly higher than those that can be freely purchased individually. over, it is not always possible to say which of them might be needed at a certain moment.
What are the peorators
Peorators are distinguished by the following features:
- power (domestic, semi-professional and professional);
- type of attachment of the nozzle;
- type of impact system mechanism;
- The location of the motor in the peorator;
- type of power supply;
- number of operating modes.
Different torches have different wattages that are counted in joules. Household gorators weigh no more than four kilos and have a power of up to five joules. They are enough for home repair work, they are good for a summer cottage or a garage. These gorators are suitable for uncomplicated work and are relatively inexpensive. Semi-professional torches are more powerful. in the range of 5-7 joules. They weigh considerably more (up to 8 kilograms) and can be used for serious building tasks. They can withstand continuous operation and handle tasks “in flux. They can handle most applications: they can break through concrete walls, partitions or even steel grates. Professional peorators are the most powerful. they are designed for professional builders and repair crews. The cost of a torch goes up as its power increases.
Peorators differ in the type of attachments. There are three types. SDS-Plus, SDS-Max, SDS-Top. SDS-Plus is a mount for inexpensive domestic or semi-professional universal peorators. The SDS-Max is used in professional machines. SDS-Top is a highly specialized chuck that is designed for drilling small holes, this type of attachment is reliable and durable.
The percussion mechanism is pneumatic or electromagnetic. In most cases a pneumatic system is used in the percussion mechanism. Electromagnetic is specific and requires more accuracy, but the holes are faster to make and the mechanism itself is more durable.
The motor of the rotator can be positioned vertically or horizontally. Vertical chucks are shorter and therefore better cooled and can be operated for long periods without interruption. But they are bulky and harder to use in hard-to-reach places, so in most cases, the motor is placed horizontally to make it easier for the worker to use the tool.
Inexpensive domestic torches are usually powered by the mains, while more professional models are often equipped with a rechargeable battery. Naturally, the cordless torch is more convenient. it doesn’t need any cords at work. The power difference between them is vanishingly small, so both types are used by professionals. The battery-powered peorator can also be useful in the home, but the presence of a battery automatically increases the cost of the tool by two or three times, so you need to choose according to your needs.
The final difference between gears is the number of operating modes. Inexpensive models have two operating modes. drilling and drilling-impacting. The more expensive professional models have three types: drilling, drilling-impact and only impact. With the third operating mode, the torch can be used as a jackhammer, which is often necessary in construction or repair work.
What the peorator can do? How it works?
Is it possible to do without the accelerator at home??
How were holes drilled in concrete in the past?? A special tool, the flat boring hammer, was used for this. In essence. it is a hollow tube of desired diameter, along the end cut of which were cut “crown” teeth.
Masters of the older generation are very familiar with this simple “hand peorator”, the hatchet
To make the hole, the hatchet was prepared, a weighty hammer. A clean rag was useful in the work, to wipe sweat that would occasionally run down the face from excessive effort, and a set of “tough words” helped ease the pain when the hammer hit not a flat baton, but the fingers of the hand holding it. During this drilling process, the flat baton was periodically rotated around its axis, and the process continued until the hole reached the required depth. Then, more often than not, a hollowed-out wooden plug was tightly driven into it, into which one could either hammer a nail or screw in a screw already.
Productivity?. no! The speed at which the hole was made?. it’s a matter of luck. There were times when I ran into such a tough fragment of rock fill that the “procedure” required several runs with pauses, and sometimes I had to abandon the original hole altogether. It was even worse when a reinforcing bar was in the way of the hatchet.
The author of these lines received his apartment at the end of 1991. A new nine-storey reinforced concrete building with bare walls and windows of dreadful quality with huge slits on the perimeter. I had no experience in construction work when I was young. you had to learn on the spot. There were not many tools available, but a hatchet and a hammer were. And the process of hanging lockers on the walls and string rods on the ceiling is engraved in my memory very well.
Being on a business trip. I bought an electric drill of Voronezh assembly “Energia” at Tushino Radio Market. For those days it was a real “wonder of technology”, even with a RPM regulator on the shutter release button. But most importantly, the kit included a nozzle designed for percussive drilling.
The bit on the drill, which created some effect of drilling and hammering
The drill chuck was unscrewed from the chuck, then the nozzle was put on the cylindrical neck around the spindle and tightened with two screws. The spindle had two splines that meshed with the hole in the coupling gear inside. After that the chuck was screwed to the spindle of the bit, it was possible to install and tighten the drill bit and start working.
The principle was simple “to the point”. rotation was driven through a socket, having a serrated notch that slipped over the same serrated notch in the body of the bit while the drill was pressed against the surface where the hole was made. It created an equivalent of translational motion of the drill bit in addition to the torque. By the way, this is the principle by which many electric drills still work, positioned as equipped with an impact function.
The principle of developing progressive force by transmitting rotation through a pair of toothed friction clutches is still used in many power drill models. The scheme is extremely imperfect, and everything in the torches is much more complicated.
I can’t say that working with such a bit has gone “without a hitch”. In order for this “percussion” to have any visible effect, I had to push the drill with all my weight. But in many areas (for example, when drilling holes in the wall in the area under the ceiling), it was simply impossible to apply such force, and it made more noise without any visible benefit. The beater bits with this kind of drilling in the concrete “wore out” very quickly. And, worst of all, the gearbox of the drill got terribly hot, i.e. I had to take frequent and very long breaks. The process consisted of alternating drilling operations and processing a hole with a flat, if a hard stone was encountered.

To cut a long story short, the expectations were clearly not met. So 8 years later, when the overdue repair was started, already at a higher level, the drill as a tool for such operations. was not even considered. At that time perforators were not such a rarity. And there were many ads in newspapers offering such services. the happy owners of the tool made good business on it. A call to such an ad informed about the price. a dollar per one drilled hole! The work was large-scale, so it was decided that it would be cheaper to buy your own peorator. At that time level of wages it was a terribly expensive purchase (comparable to a monthly salary), but I have never regretted it. Since then the torch (already the third in 17 years) always occupies a place of honor in my tool kit. All the more that the of such tools are not so “biting”.
Here it is, the “old guy”, repaired many times, but still faithfully in service for more than ten years. For some reason I still can’t bear to throw it away.
In short: no need to doubt! A good owner should have one. there is always a use for such a tool. And the owner will get rid of many problems with a variety of operations in the construction or repair, as well as in everyday practice.
