Peorator or impact drill for the home, which is better to choose in. Which is better: an impact drill or a peorator?
This question is often asked by unsophisticated home users. Professionals do not have such doubts in principle, because they surely know that behind the external similarity hides a great difference, predetermining the capabilities of these two tools.
Drill originally designed for drilling holes in low density materials. in wood, plastics, soft metals. The addition of the percussion function has greatly expanded the capabilities of this tool, allowing in addition to everything else, to easily drill into masonry and structures made of low-marble concrete. However, like impact drills, with the proper accessories, they are capable of working with fasteners. For all their universality drills have rather modest dimensions and cost not an example cheaper than rotary drills. Thus, the main reasons of impact drills popularity among domestic consumers are their versatility, compactness and affordability.
Correspondingly, rotary drills are heavier and more expensive. If we compare tools with identical power, the weight and price advantage of the peorator is obvious. For example, a Makita HP 2071 1000-watt two-speed drill weighs 2 kg.4 kg and costs about 5000 With its help you can drill a hole in wood with a diameter of up to 40 mm, in steel. up to 16 mm, and by connecting the shock function, you can “drill” into concrete with a 20 mm drill.
For a similar in power peorator M akita HR 4010 C you have to pay three times more and it weighs 6.3 kg. As far as functionality is concerned, the core drill is considerably inferior to a drill, because it only chops or drills with impact, and these two modes are unacceptable for making holes in wood and metal. But in terms of concrete drilling the designated peorator is beyond competition, as it “pulls” not only the drill of large diameter (up to 40 mm), but also the drill bit (up to 105 mm). In addition, this tool can easily replace a jackhammer and greatly facilitate the work on the device niches and openings, laying communications, chipping old ceramic tiles, etc.п. Of course, such a tool is intended exclusively for professionals and is hardly useful in everyday life.
But even among peorators you can find lightweights: for example, a Makita HR 1830 weighs only 1 kg.7 kg, and is inferior in price to hammer drill Makita HP 2071. Both of these tools operate in the drilling and hammering modes. And the drill can be used to make technical holes of much larger diameter in concrete (without regard to hardness), wood, and steel.
So what’s the difference?? the first point is the difference in power consumption: the drill being compared has a power consumption of 440 W, the drill has a power consumption of 1010 W. And this is the corresponding load on the grid and the cost of paying for electricity on the one hand, and the performance indicator. on the other hand.
But the main difference lies in the purpose, in particular in the main object of the force application. For a drill, drilling in concrete is an additional option, and in the drilling mode with a hammer the tool works on “self-destruction” (about this below). A peorator. A machine that can easily smash through monoliths can’t drill precise holes in steel, wood or plastics. the reason of it is constructional features of impact mechanisms of drills and lever drills and used chucks for fixation of accessories.
In an impact drill, the impact is generated mechanically. It’s very simple there. Two toothed ratchets in the drilling mode without impact rotate with their teeth as one unit. When the shock function is activated, the inner ratchet (located closer to the motor) is fed back, and the outer ratchet begins to “count” its teeth with its own. As a result, no impact energy is generated as such: the impact force is predetermined by the height of the teeth and the pressure exerted on the tool by the user, while the frequency of impacts is determined by the number of teeth and the rotation speed.
Hence the “self-destruction” mentioned above. No matter how strong and wear-resistant the material used for manufacturing ratchets may be, sooner or later the teeth will “stick together” and the impact mechanism will finally fail.
The nature of the impact in ratchets is completely different. The crank mechanism converts the rotation from the motor into a reciprocating motion that is communicated to the piston. This in turn actuates the striker, but not directly, but through an air gap which reduces the load on the piston, thus contributing to the durability of the tool as a whole, and reduces recoil. Such percussion mechanism is three times more efficient and, of course, more reliable than the ratchet drill. In the Makita range of submissions, the impact energy ranges from 1.3 to 19.7 Joules (models HR 1830 and HR 5210 C. accordingly).
From the above it is already possible to draw some conclusions. For example, that if intensive works on concrete drilling are forthcoming, an impact drill will “die” soon enough, and the “heavy” one will not overcome at all. And it’s true. But don’t be enchanted by the versatility of the three-mode orators, which are claimed by the manufacturers to be a jack-of-all-trades. As a rule, these are tools of light (up to 4 kg) and medium (5-8 kg) class. Such tools, and “heavy” too, are equipped with SDS quick-action chucks. plus and SDS. max. designed exclusively for special attachments. drills, blades, etc Shafts of which have quite a specific shape (number and existence of slots). Consumables for rotary drills are much more expensive than conventional drills, and the use of the latter is not possible due to the specifics of the chucks. In order to expand the capabilities of rotary drilling tools, manufacturers quite often equip their models with additional cam chucks mounted in standard holders of SDS type with special adapters. The tool thus becomes more cumbersome, and chuck runout significantly increases, which is not good for quality. Interchangeable chucks are an alternative for more precise drilling. In this case, the basic SDS chuck can be easily removed and replaced with a standard cam chuck thanks to an adapted tip. For cylindrical drills. Example. Makita HR 2811 FT with a removable SDS chuck. plus. It is worth noting that this type of assembly is not very common and has a significant impact on the tool price.
What is better for the home peorator or percussion drill. Which drill to choose: a rotary tool or a core drill?
Especially in spring one wants to upgrade something from the tool. Even if a major renovation is not yet planned, perhaps a cosmetic repair would not hurt to plan. You need a tireless and reliable helper. For the home handyman who has decided to seriously engage in housekeeping, there are two options. an impact drill or a peorator. Impact drills are universal tools. Greatly suited for drilling holes in metal, plastic, wood, tile, and brick. But it is important to consider that the chuck and percussion mechanism of the drill is not designed for significant axial forces. Almost every impact drill has a switch that disables the impact function. Impact drilling is easy and uncomplicated. The drill can be used to drive self-tapping screws or screws. In doing so, the drill is used in hammerless mode. The drill is a kind of mechanical woodpecker. Its element is reinforced concrete. Drill holes in hard materials, even natural stone, granite and concrete. Can chisel with different types of chisels, e.g., for flush wiring. It has similarities to an impact drill, but provides a more vigorous blow in the drilling direction. There are impact drills that work like a jackhammer. These peorators can quickly remove screed from concrete bases, remove old tile or plaster.
DIY enthusiasts often face a dilemma: which drill to buy for the home. a hammer drill or a rotary drill? Both tools are designed for drilling. Both have a hammer function.
It’s not a question of which is better. it’s a question of what you need the tool for. After all, it is one thing to drill hundreds of holes every day, putting out reinforced concrete, making holes for sockets, and quite another thing to drill a wall once every couple of months to hang a shelf or cornice. An unsuitable tool will either fail quickly, or lie idle. That’s why it is worth to understand the difference between an impact drill and a rotary drill. Let’s start with the principle of operation.
Operating principle and special features
First. the impact drill and the rotary hammer differ in terms of the hammer mechanism. The drill is based on mechanics. the friction of the gears. The impact is weak, with a small amplitude. This is compensated by a high frequency (about 30-50 thousand blows per minute). You must apply firm pressure to the tool when working.
The impact of the peorator is realized by pneumatics (in the cylinder there is a piston that transmits the motion to the striker). Amplitude and energy of the blow is high, but no additional efforts are required. The frequency of blows, on the contrary, is relatively low (up to 4-5 thousand per minute).
The second one is the operating modes. In a drill, the impact complements the rotation, t.е. The first is impossible without the second. There is also a simple drill. Peorators usually have 2 or 3 modes: drilling with impact (basic), drilling without impact and chiseling (clean impact).
Third, efficiency. With equal power of tools the possibilities of a drill are much more modest. In other words, to drill the same hole as a peorator, the drill will use 2-3 times more energy. And there are some things it cannot do at all.
Differences in application
An impact drill can handle brick, cellular concrete, other lightweight concrete. But drilling in these materials will be slow and labor intensive. The reason is that the impact energy of the drill is low. What is convenient is to drill wood and metal, as well as to screw fasteners.
Peorator is most effective for drilling in concrete or stone. If you work with it on wood or metal, the holes are not as accurate as with a drill. A cam chuck is installed in the chuck for these works, but the runout is still present.
Drill bits, chisels, picks, and shovels are “native” accessories for the torch. It is “heavy artillery” for the corresponding tasks. Can, for example, remove tiles or chisel grooves.
So what to choose: an impact drill or a torch? Let’s summarize the main points:
- Impact drill. low impact force. Can drill into brick and concrete, but not very effective. It consumes a lot of power. Not recommended for intensive work. If you often drill with a hammer, the gears of the percussion mechanism wear out.
- Peorator. you can drill and chisel concrete of any density, stone, brick. The core drill allows to make rather wide holes. Some models have a jackhammer function. If necessary, you can drill in wood and metal, but a) with little precision; b) not very handy (because of the heavy design).
The difference between a peorator and an impact drill
The main difference between an impact drill and a peorator is its design and scope of use. Whereas a drill is used mainly for chiselling and drilling, and only optionally for drilling, a drill, even with an impact mechanism, is mainly used for drilling.
Technical characteristics of drill and geared tool are considerably different: in drill the impact is produced by displacement of gear wheels in ratchet mechanism, but in geared tool the impact is produced by compression and rarefaction of air in pneumatic chamber. The hammer is driven by the roller bearing or crank mechanism.
Rotation speed of a drill is higher than that of a geared tool, since it is designed specifically for drilling, the geared tool mechanism wears down faster when drilling at high speed. But the impact force of a peorator is greater than that of a drill, which allows to make holes in hard materials quicker.
The chuck of both tools is different: a drill chuck is a quick-action chuck, and the speed drill is a SDS Plus or SDS Max chuck. SDS Plus is found in domestic models and allows to work with drills and drill bits 30 mm. SDS Max chuck refers to professional drill presses and allows you to drill holes up to 120 mm in diameter.
When to use a drill
The drill is useful for making holes of small diameter. Most commonly used for metal, wood and brick drilling. An impact drill can be used for infrequent drilling in concrete, brick, or stone.
The drill can be used to screw and unscrew fasteners as well as to deburr, grind and polish surfaces using various attachments.
When to use a peorator
A peorator is needed for demolition and construction work, including making holes in stone, concrete, and reinforced concrete. Long operating time and powerful impact that enable it to operate effectively virtually nonstop for the entire shift.
With the help of a drill can cut holes for sockets, pipes and utilities, even in concrete walls with a diameter up to 120 mm.
Most often the peorator is used for dismantling walls, flooring, chipping old tiles, window sills, creating new door or window openings. Also useful when you’re strobing. creating shallow channels in the walls where you’ll lay wires or plumbing pipes. All of this is possible with a chisel-less drill.
What to choose for your home: impact drill or rotary tool
A regular drill is good enough for simple repairs, hobby work or the occasional furniture assembly, hanging shelves and curtain rods. If the walls of the house are made of concrete, new solid brick or other durable materials, you will need an impact drill. A cordless drill is good for the home: it is light enough and mobile enough to work even under the ceiling or where an extension cord cannot reach.
If you’re up to serious repair work with the removal of tiles or laying wiring, you need an entry-level rotary drill: power up to 1000 watts and impact force up to 2.5 J. It is best if it works in three modes: chiseling, drilling without impact, and drilling. It is slightly larger than a drill and is capable of performing basic tasks, including drilling or boring in concrete and other hard materials. Just like a drill, a handheld torch can be self-contained with its own battery.
But if you are going to demolish a partition or create a niche in the wall, you might prefer a professional model with more power. Corded models are more common, because the high weight of an already heavy tool is what separates the cordless torch from the cordless tool.
Can a peorator be used like a drill?? It is possible if the machine has a drilling mode. A peorator cannot boast of high speed when making holes: its design puts a limit on the speed. In drilling mode, for example, the rotation of the auger is only needed to remove dust from the working area.
You may need an extra quick-action drill chuck for your screwdriver, which is not always included. When selecting the right model it is worth looking into this issue beforehand.
Whether you choose a drill or a rotary tool, remember to take good care of them and make sure they do not overheat. Peorator also requires lubrication of the core drill shank, but before that it is necessary to wipe dust off the core drill.
And what is the difference between a Peorator and an impact drill. What is the difference between a drill and an accelerator?
1) Impact drill
It begs the mute question, “Why are we talking about an impact drill and not a regular drill??”. The answer is. In today’s market, conventional models have long been considered antique and almost no one produces. Impact models, on the contrary, are put in large-scale production. Their technology has improved the capabilities of the conventional model. So, despite the fact that the drill. it is for any home handyman “tool for every day”, now when you buy a regular drill you will spend a lot of money and will be significantly limited in capacity. Consider the functions of an impact drill:
2) Peorator
The presence of the torch in a repair job will add to the capabilities listed above
What is the difference between a peorator and an impact drill?
The principle of the drill is two toothed ratchets. When you work by pushing on the material to be worked, you make it jump “on the teeth”. The disadvantages of the method are the low amplitude, the great effort required and the high degree of recoil. in addition, with constant use, the ratchets wear out and have to be replaced with new ones.
Peorator is devoid of these disadvantages due to fundamental differences in internal structure. This device is more durable and powerful, especially in holes in hard surfaces. Speed is much higher and output is less than that of an impact drill.
At the store “220 Volt” you can buy peorator or drill, depending on your goals and objectives. However, consider the following when comparing the peorator to a drill:
Peorator is more expensive than a drill of the same level
Drills peoratora have higher requirements, therefore, the price is more expensive than usual
Special drill bits for rotary drilling machines are highly stressed, so they have a special chuck design. Consequently, it is impossible to use a regular drill without an adapter
The use of an adapter for a conventional drill makes conventional drilling difficult, if not impossible.
Therefore, when choosing power tools, you should know the specifics of future repair work.

Peorator for the home: general recommendations
What is the best tool to choose for the repair of the apartment?
The high-class torch, the gearbox is made of metal, a long cable to the network, complete with a chuck and a case.
Huge problem with the dust protection. Easily clogged with dust when working extensively. After I pressed the switch lock I could not disconnect it. It is clogged with dust and had a hard time blowing it out. But it is possible to restore the work of the mode switch only by taking apart the peorator.
A very reliable tool on the outside, plus, as it turned out, a high-performance one as well. It can be used in masonry work, piercing, drilling with a core diameter of 65 mm. But the chisel mode is not suitable for concrete work: the tool is not powerful enough for such work. The manufacturer refers to this model as a professional one, but the lack of normal dust protection spoils the whole impression.
Bought when I had to make repairs myself. Great drill, no other drill can replace even the most powerful impact drill. All the holes are made in no time. In supporting walls, you can make a hole with a diameter of up to 10 mm. I only use it with Makita drills. Probably not suitable for professionals, but that’s all I need.
Impact drill functions
Thanks to a variety of drills can make holes in different materials:
- to drill wood take drills for metal or wood, in some cases. feather drills;
- when it is necessary to make a hole in metal, durable drill bits of special design are used;
- The javelins, designed to work with glass and ceramics, help me drill neat holes in tiles without damaging them;
- core bits help in cases when you need to make holes of large diameter;
- Pobedite drills are ideal for drilling in hard materials like bricks and concrete.
impact drill
In addition to the usual ones, you can use additional attachments. They permit a considerable increase in the functionality of the appliance.
Use the grinding wheel attachment for fast, high-quality sanding. The steel wire brush attachment will help to grind any metal surface. For roughing work, a twisted wire bit is used, and higher-quality work is performed with a knurled brush.
If you purchase a special attachment, the drill can act as a mixer: it is able to quickly and thoroughly mix the mortar.
A drill with a switched-off hammer action also works as a substitute for an electric screwdriver. You can use it to tighten and loosen screws, self-tapping screws or screws, assemble furniture, hang shelves at home and perform other operations.

Professional tools
the name probably already speaks for itself, i.e.е. these models are designed specifically for professional activities. These power tools must be able to withstand continuous, long hours and high loads. Generally, they have high power and weight, but there are also light, low-power professional options, such as compact electric saws for working at heights or screwdrivers for assembling furniture. Professional power tools have a wide range of applications and great functionality. The presence of attachments in professional equipment is extremely rare and completely unnecessary, because they will only reduce its regular capabilities, which, in the case of such a tool, is absolutely unnecessary. this all influences the price of professional power tools, which is significantly higher than that of amateur tools.
Both impact drills and rotary hammers vibrate a lot in your hands when working in chisel mode. This is not very important for occasional use, but professionals should take note. Continuous work with such a tool will inevitably lead to joint diseases, so the presence of an anti-vibration system is one of the most important parameters of a professional tool. And it should be noted that an active anti-vibration system based on balancing counterweights is found only in rotary drills.
In percussion drills, by an anti-vibration system is meant at best a shock-absorbing suspension, and more often just rubber-coated handles. Besides the fact that the drill vibrates in the chisel mode no less than a peorator.

Operating modes
Each torch has three operating modes: drilling, drilling with impact and impact mode. Depending on the material to be worked with, one or another mode is selected.
Drilling mode is used for making holes in hard materials like tiles, wood, plastic, metal, etc. The torch performs the function of an ordinary drill in this mode. To activate it, turn the rocker switch to the position opposite the drill symbol.
Drilling with the torch
How to drill metal with a torch? Choose the drill of the required diameter on metal. If the diameter of the hole or the thickness of the metal is too large, it makes sense to start with small bits, gradually enlarging the hole you are about to make. Drill mode. It is necessary to chisel the surface to prevent the drill from “walking”. Let’s begin the work, controlling heat of the motor.
How to drill with the torch? This operation is also carried out in drill mode. Special drill bits for glass and ceramic tiles with a tungsten carbide tip or pobedite drill bits are used.
Mark the place of the hole, put a masking tape on top (to prevent the drill from wandering), or mark the drilling points. When the tile is drilled through, change the drill bit and the mode to drilling with impact (in the case of a concrete wall).
Impact drilling mode is indicated on the toggle switch by a drill and hammer. Used for drilling in fragile materials such as concrete, plaster, brick, etc. In this mode, the drill bit simultaneously rotates and strikes, which destroys the material and throws dust and debris to the outside.
The impact mode is used for jackhammering, chiseling, and gouging. This mode is indicated with a hammer on the toggle switch. Depending on the function and characteristics of the material to be drilled, various attachments may be used: blades, picks, chisels, etc. This mode does not rotate the tool but only chisels.
Many modern rotary table saws also have a reverse mode. It is very useful if the drill gets stuck. When operating in this mode, the motor rotates in the opposite direction.
Impact drill
It differs from a regular drill in that it has an in-built mechanism for reciprocating motion-impacts. Their cartridges are similar in design, look and feel the same. Three-jaw chucks are used to hold a work tool, a drill bit, for example. This design moves the jaws toward each other as the outer cage of the chuck rotates, and that is how the drill is clamped.
The picture below shows the internal workings of the tool:
The striking mechanism is realized by a ratchet made of movable and not movable ring with teeth on one of the sides. This mechanism does not involve longitudinal movement for a long length. the amplitude of the movement of the drill is within a couple of millimeters, and its energy depends on the force of pressing the impact drill to the wall and is in the range of units of joules (J). That is, it rather does not strike but vibrates in the material to be worked.
Impact drill
It differs from the conventional drill by its built-in mechanism for translational motion. impact. Their chucks are similar in design, look and feel. Three-jaw chucks are used to hold a work tool, a drill bit for example. This design moves the jaws against each other as the outer cage of the chuck rotates, which is how the drill is clamped.
The picture below shows the inner workings of the tool:
The hammer mechanism is made with a ratchet made of a sliding and a non-sliding ring with teeth on one side. This mechanism does not imply longitudinal movement for a long time. the amplitude of the motion of the drill is within a couple of millimeters, and its energy depends on the force of the impact drill to the wall and is in the range of units of joules (J). That is, it does not strike but rather vibrates into the material to be worked.
Tips for using the torch
Here are a few tips that will allow you to use the torch more productively and safely:
- When drilling and chiseling, do not apply too much pressure to the body of the tool, this only overheats the motor, wastes strength, and does not speed up the work process.
- Selecting the right accessories for each job is the key to getting the job done quickly and successfully.
- When you do localized drilling work with a peorator, you can avoid long cleanup times by keeping the hose of a working vacuum cleaner under the drill or chisel point. If screws need to be driven into the concrete surface, metal anchors are inserted into the drilled hole. If the expected loads are not very heavy, you can limit yourself to plastic dowels.
- Use water to cool the drill bits and get rid of dust only after you are familiar with the composition of the drill bit. The fact that some carbide drills can break when cooled by water.
- For larger holes with larger diameters, use special diamond drill bits instead of drills. it will reduce labor costs and save time.
What is the difference between a drill and a rotary tool?
An impact drill is great for the following type of work:
- Drill holes in different materials (including wood and plastic). In doing so, it is possible to switch off the shock function, if necessary.
- Make (chisel) holes in some hard materials. With the impact function, even masonry can be drilled quite quickly.
- Screw in or out self-tapping screws, bolts and screws. Only when the impact function is switched off.
With the rotary table in addition to the above-mentioned works it is possible to
- Punch holes in very hard materials (for example, in reinforced concrete).
- Use different types of chisels for chiselling. This feature is only suitable if a small hole or gutter in a concrete or masonry wall needs to be made.
These tools (impact drill and rotary drill) have quite a lot in common, but there are still some differences. To understand them better, we must first understand how an impact drill works. It consists of the following: there are a pair of toothed ratchets, which interact with each other. In the impact mode, their impact on the material takes place. This principle has the following disadvantages:
- The harder the material, the more force is required.
- Low amplitude with high kickback.
- Rapid wear of the ratchet teeth.
The torch has none of these disadvantages. Mainly because its construction is very different from that of a drill. Its mechanism is very similar in some details to that of an automatic weapon. It is particularly different when working on hard materials. Less recoil and higher velocity. But consumables for this tool are more expensive than for a drill.
But this does not give a reason to completely abandon the impact drill. If there is no need to make holes in very hard materials, then it is most appropriate to use it. In addition, it will cost less than a peorator of similar level.
What else is different between the impact drill and the torch? The difference is that the drill allows you to use regular drills without extra attachments, while you need additional adapters for this purpose with the peorator. They make the tool uncomfortable to work with, t.е. increase its length.
Therefore, before you buy a drill percussion or peoratora, you need to know exactly what kind of work you will perform them, and with what material will work. For example, for wood and metal with brick walls, it is best to buy a percussion drill, and to work with concrete walls will need a peorator.
The main features of the tools
Impact drills are usually equipped with the following types of chucks:
- Toothed (a.k.a. key chuck). The drill bit is held in the chuck by a special wrench that comes with the drill.
- Quick-clamp. Allows the drill bits to be driven in without much effort. They are held firmly enough in such a chuck. No wrench can be used. Drill bits are usually fitted with an SDS-PLUS mount that can only be used with special drill bits. There are also tools with normal chucks.
There are electric drills, which determine the optimum torque when screwing screws. You must specify the type of material and the type of work required. The tool itself does the rest.
Main tool features
Impact drills are usually equipped with the following types of chucks:
- Toothed (otherwise keyed chuck). The drill is fastened in it with a special wrench that comes with the drill.
- Quick-clamping. They can be driven in without much effort. They are firmly enough retained in the chuck. No wrench is used. These chucks usually have SDS-PLUS fastening, which allows you to use only special drill bit types. There are also tools with standard chucks.
There are power drills that develop the optimum torque for tightening the screws. You specify the type of material and the type of work required. The tool itself will do the rest.
What you can choose: a hammer drill or a rotary drill?
- Short-term operation of the device up to 35-40 seconds;
- the use of quality sharp drill bits;
- consideration of the conditions in which the work is to be performed.
Peoratorov capacity of 800 to 1500 kilowatts and weighing from 2 to 11 pounds are usually somewhat larger than an impact drill. In such devices, the motor can be positioned either horizontally or vertically. Many are also equipped with SDS chucks. The technical specifications of the tools usually indicate the frequency of blows per minute and their strength. In low-power devices, it is usually possible to regulate the speed, which allows them to be used as an electric screwdriver.
