Impact drill or perforator what to choose

Peoratorator or impact drill for the house, what to choose? What’s better: impact drill or rotary drill?

This question is often asked by unsophisticated laymen, who buy tools for home use. Professionals have no such doubts, because they know for sure that the external similarity conceals a great difference that predetermines the capabilities of the two tools.

The drill is primarily designed for drilling holes in low-density materials. in wood, plastics, soft metals. The addition of the impact function has significantly expanded the capabilities of this tool, making it possible to drill into masonry and low-barrier concrete easily. Just like impact drills, they are capable of working with fasteners if equipped with the proper accessories. For all their universality, drills are quite modest in size and cost not an insignificant amount of money compared to piezometers. Thus, the main reasons for the popularity of impact drills among domestic consumers include their versatility, compactness and affordability.

Correspondingly, the torches are heavier and more expensive. If we compare tools with identical power, the weight and price advantage of the torches will be obvious. For example, a Makita HP 2071 thousand-watt two-speed drill weighs 2 kg.4 kg and costs about 5000 With its help you can drill in wood up to 40 mm in diameter, in steel. up to 16 mm, and by connecting the shock function, you can “drill” in concrete with a drill 20 mm.

For the similar in power peorator MaKita HR 4010 C it is necessary to pay three times more and it weighs 6 kg.3 kg. In terms of functionality, the torch is considerably inferior to a drill, because it only chops or drills with a hammer, and these two modes are unacceptable for making holes in wood and metal. But in concrete drilling the above mentioned geared tool is beyond competition, because it can handle not only drill of big diameter (up to 40 mm), but also the core 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 utilities, chipping old ceramic tiles, etc.п. Of course, such a tool is intended exclusively for professionals and is hardly useful in everyday life.

Peorator or impact drill for the home, what to choose in. What is better: an impact drill or a peorator?

However, even among the rotary drills there are “lightweights”: for example, a Makita HR 1830 weighs only 1 kg.7 kg, and is inferior in price to the Makita HP 2071 impact drill. Both of these tools work in the drilling and hammering modes. And with the help of a drill can arrange technical holes of much larger diameter and in concrete (without regard to hardness), and in wood, and in steel.

A logical question arises: what then is the difference between the? First of all, there is a difference in power consumption: The power consumption of the compared drill is 440 W, while the power consumption of a drill is 1010 W. And this is the corresponding load on the network and the cost of electricity on the one hand and the performance indicator. on the other hand.

But the main difference is in the purpose, in particular in the main object of application of force. For drills, drilling in concrete is an additional option, and in the mode of drilling with impact the tool works on “self-destruction” (about it below). And a peorator. The drill that destroys monolith with ease does not provide high accuracy of drilling holes in steel, wood and plastic. The reason is constructional features of impact mechanisms of drills and rotary 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 you activate the shock function, the internal ratchet (which is located closer to the motor) moves back, and the external ratchet starts to “re-count” its teeth with its own teeth. 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, and the frequency of impact 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 the ratchets are, sooner or later the teeth will “stick together” and the percussion mechanism will finally fail.

The nature of the blow in pen rotors has an absolutely different character. The crank mechanism converts the rotation from the motor into a reciprocating movement which is transferred to the piston. The latter in its turn activates the striker, but not directly, but through an air cavity which reduces the load on the piston and thus contributes to the durability of the instrument in general, and reduces the recoil. Such impact mechanism is three times more effective and, of course, more reliable than the drill “ratchet”. In the presented range of Makita rotary table rotators, the impact energy varies from 1.3 to 19.7 Joules (HR 1830 and HR 5210 C models). respectively).

Some conclusions can already be drawn from the above. For example, if you are going to do intensive concrete drilling work, the impact drill will soon “die”, and the “heavy drill” will not overpower you at all. And it’s true. But do not be enchanted also by the versatility of three-mode orators, which are declared by manufacturers as a jack of all trades. As a rule, they are tools of light class (up to 4 kg) and medium class (5-8 kg). Such rotary tools, and “heavy” as well, are equipped with SDS. plus and SDS. max. The consumables are designed exclusively for special attachments. drills, blades, etc which shanks have quite definite form (presence and quantity of slots). Consumables for peorators are much more expensive than conventional drills, and the use of the latter is not possible due to the specificity of the chucks. In order to expand the capabilities of their rotary tools, manufacturers quite often equip their models with additional cam chucks, which are mounted in standard holders of the SDS type by means of special adapters. The tool thus becomes more cumbersome, and the runout of the chuck significantly increases, which is not good for quality. Interchangeable chucks are an alternative for more precise drilling. In this case, the main SDS chuck is subject to easy dismantling, and in its place thanks to adapted tip a regular cam. for cylindrical drills. Example. Makita HR 2811 FT with a removable SDS chuck. plus. It is worth mentioning that such design is not very common and has a significant impact on the price of the tool.

What is a peorator??

Peorator is also an electric tool, which differs from drill by details of its design and specifics of its use. In addition to rotating the tool, it also reciprocates. To create this movement, a special unit is provided in the peorator: a swing (drunken) bearing. in straight peorators, and a crank mechanism. in barrel-type peorators. Both parts convert the rotary motion into a reciprocating motion and interact with the piston to transmit the shock impulse to the bit.

Despite the fact that the peorator is similar to a drill, it is much more often used for dismantling work and is usually not used for work with fasteners. This is explained by the greater impact force of the peorator, its greater weight, as well as the absence of the drill‘s chiseling mode.

How to choose a peorator for the house, which model is better, what is the difference between a peorator and a drill, video

Choosing the right drill tool means making home repairs easier for a long time. How to choose the peorator successfully, so as not to overpay for a brand and to receive high-quality equipment?

A few decades ago, home use was limited to high-powered electric drills with metal and concrete drills. Truly branded, specialized tools were sold only abroad, you could not just go to a construction supermarket and choose the right device.

Everything is changing, and the shortage of goods for the population has turned into a retail trade associated with turnover and competition. Now there is no problem with availability, but there are problems with the selection of the right tool model, choosing an honest manufacturer.

What is the difference between a drill and a rotary tool and vice versa?

The oscillating drill is characterized by a longitudinal axial movement of the working part, similar to an impact drill. This is why peorators are confused with a heavy drill. In a word, there is practically no difference, but the peorator functions on the basis of pneumatics, while any impact drill (heavy) operates thanks to mechanics.

Hence the difference in surface speed. Drilling holes in concrete, brick and masonry walls pneumatically reduces the physical strain on the user. For any percussion drill similar work is associated with great fatigue, and the mode “percussive drilling” saps the internal nodes of the drill very quickly.

We come to the conclusion that the rotary drill should be bigger and more massive than a drill with percussion function.

Design and Characteristics of a Peorator

All peorators are divided into three types according to functionality:

  • Single-mode. Only drill and impact function. often such torches are not used in daily life, but as professional auxiliary equipment of narrow purpose.
  • Two-mode. Impact drilling plus classic drilling mode or chiseling only.
  • Three-mode. The tool is equipped with all the functions mentioned in 1 and 2.

The choice of gator is based in the first place on the characteristics of power and impact force. The higher the value, the better the chosen torch.

Tool’s impact force is sometimes not proportional to power due to design features.

What chuck for a geared tool to choose? For works around the house or household, the keyless quick-change chuck is the best choice. Changing tool bits is fast, easy and comfortable.

  • Light. Up to 4 kilograms. Power max. 700 watts. They have only SDS-plus chuck for a drill not more than 26 mm.
  • Medium. 4 to 8 kg. Power 700 to 1500 watts. Equipped with both SDS-plus and SDS-max, depending on equipment.
  • Heavy. than 8 kg. Power above 1500 watts. Equipped only with SDS-max chucks up to 60 mm in diameter.

Bosch equips the latest models of its rotary tools with SDS-top chucks for diameters from 16 to 25 mm.

Energy and frequency of shocks

The impact function measured in joules is very important for the puncher. The impact energy affects the performance of the device, as well as the diameter of the hole to be cut. This is one of the most important factors for day-to-day work with the rotary hammer drill.

It is essential that the impact drill at the “maximum” will quickly exhaust its resource, and peoratorom perform this work for a long time without wear, especially the single-mode model.

Blow frequency also affects the working speed of the tool. The more often the peorator piston hits the element, the faster the hole is punched.

It turns out that energy and frequency determine the performance level. When you choose your own drill bit, you need to estimate the amount of drilling work, then use the specified impact frequency to calculate the approximate performance.

How to choose a peorator for the home

It is best to start your selection based on weight and power. Super-performance models for the home definitely won’t be needed.

Peorators for home use are mid-range tools in terms of cost, power, and weight.

Appropriate criteria for the home environment and the brands listed below:

  • Power capacity of 600 to 900 watts.
  • Impact between 1.2 and 2.2 Joules.
  • Three-mode medium peorator. Drilling, drilling with impact, impact without rotation.
  • Adjustable speed.
  • Jamming safety clutch.
  • Quick-action chuck.
  • Replaceable brand chuck included.

There are three leading brands based on these characteristics:

  • Makita. Light enough drills and torches, with a warranty of a few years. Proven as a tool for everyday household chores, light repairs. Mid-market price, easy to use. What brand to choose for your home? Users refer to Makita RK 2450 model. The necessary (useful) power of 700 Watts, Impact of 3 Joules, speed up to 4,5 thousand.
  • Bosch.German quality and build. Leaders in the field of professional power tools and equipment for home works. All models are time and weather tested. Peorators are equipped with a function of precise speed adjustment of the attachment (drill, drill bit). When buying equipment from this manufacturer, pay attention to the color of the body. Blue classifies exactly the professional purpose. Popular model. Bosch GBH 2-24 DF. Powerful 790 watt, 2,7 Joule impact, interchangeable SDS-plus chuck and classic quick-action chuck included.
  • Hitachi. The best tool on our market from Japan. are in the same category as Makita, but some models of power tools, including peorators, are lighter in weight. Thinking about which one to choose from this manufacturer? Pay attention to the Hitachi DH 22 PG, power of 620 watts, 1.4 Joules and weighs only 1.9 kg.

Peorator for home: general recommendations

What is the best tool to choose for renovation of the apartment??

Very high class torch, gearbox is made of metal, long cable to the mains, chuck and case included.

Huge problem with the dust protection. Easily clogged with dust. After pushing the switch lock, I could not disconnect it later. It is clogged with dust and it was difficult to blow it out. But you can restore the work of the switch only by taking the peorator apart.

Externally very reliable tool, plus, as it turned out, also highly productive. It can be used for bricklaying, piercing, drilling with a 65 mm core diameter. But the drilling mode is not suitable for concrete work: the tool is not powerful enough for such work. The manufacturer classifies this model as a professional one, but the absence of a normal dust protection spoils the whole impression.

Bought when I had to do the repair myself. Excellent drill, which no other drill can replace even the most powerful impact tool. All holes can be made in one go. It is possible to make a hole up to 10 mm in the supporting walls. I only use it with Makita drills. It is possible it will not suit professionals, but I do not need more.

The main difference between an impact drill and a rotary drill is hidden inside. To be more precise, there are absolutely different types of percussion mechanisms used in construction of these tools. And the difference is not only in appearance, but also in impact force.

  • On the drum drum beat mechanism is made by electro-pneumatic and mechanical nodes. Drum type and straight type devices have different percussion mechanism design. The straight type units use a drunken bearing that drives the piston. The piston moving in the sealed chamber uses the energy of compressed air to act on the striker, thereby moving it. The hammer strikes the rear part of the auger, which is fixed in the chuck of the instrument, by the energy of the compressed air. On barrel rotators, instead of a drunken bearing, a pinion is used, to which the rod, connected to the piston, is attached. The pinion and the drunken bearing are driven by an electric motor. The hammer mechanism of the peorator is reliable and due to this complex construction, it can develop the impact force from 2 to 20 joules

In view of the above, it should be noted that it is very quick to drill a hole in concrete with a lyator. A drill will also accomplish this task, but with a slight delay. And the delay time depends directly on such factors as the type of material, thickness, depth of the drilled hole, and power. If you need to drill a hole with a diameter of more than 10 mm in the concrete, it is better to use a peorator for this purpose.

This is interesting!The drill can drill a 10 mm hole in the concrete, but the resource of the impact mechanism will be significantly reduced with each opening.

The difference between a drill and a torch

Drill percussion is excellent for the following type of work:

  • Drill holes in various materials (including wood and plastic). The impact function can be deactivated, if necessary.
  • Make (chisel) holes in some hard materials. With the impact function, even holes in masonry can be made quite quickly.
  • Screw in or out self-tapping screws, bolts, and screws. Only when the impact function is switched off.

With the help of peoratora in addition to the above work is possible:

  • To punch holes in very hard materials (e.g., reinforced concrete).
  • Use different types of chisels for chiseling. This possibility is allowed to apply if you need to make a small break or groove in a concrete or stone wall.

There are quite a few similarities between these tools (impact drill and peorator), but there are still some differences. To understand them better, it is first necessary to understand the principle of the impact drill. It consists of the following: There is a pair of toothed ratchets, which interact with each other. Their impact on the material is in impact mode. This principle has the following disadvantages:

  • The harder the material, the more effort is required.
  • Low amplitude with a high degree of recoil.
  • The ratchet teeth wear out quickly.

The impact drill has no such disadvantages. Mainly because its construction is very different from that of a drill. In some details, its mechanism is very similar to that of an automatic weapon. It is especially useful when working on hard materials. It has a lower kickback and a higher rate of penetration. But consumables for this tool are more expensive than for a drill.

But this is not a reason to completely abandon the impact drill. If there is no need to make holes in very hard materials, it would be more appropriate to use this tool. Also, it will cost less than a peorator of a similar level.

What else is the difference between an impact drill and a peorator? The difference is that a drill allows to use usual drill bits without additional accessories, and additional adapters are needed for this purpose with the impact drill. They make the tool inconvenient to operate, t.е. increase the length of the tool.

Therefore, before you buy a core drill or peorator, you need to know exactly the type of work that you will perform them, and with what material will work. So, for wood and metal with brick walls, it is best to buy a percussion drill, and to work with concrete walls you will need a peorator.

Peorator

The main difference between the peorator and the impact drill is the design of the percussion mechanism. It can be electromechanical or electro-pneumatic. The latter is found in most models of the modern market.

The principle of operation is the following: an electric motor drives a gear wheel, on the output shaft of which a rocker or, as it is also called, a drunk bearing (1) is mounted. It drives the piston along the cylinder. As a result, the piston interacts with the ram (2) that strikes the striker (3) transmitting energy to the tool set in the SDS chuck (4). This achieves a greater impact energy and depth.

Interesting: for the same power, the impact energy of the peorator is 2 or more times greater than the impact energy of an impact drill, which is more suitable for concrete.

The second difference between the rotary tool and an impact drill is the way the bits are fastened in the chuck. If in the previous version cam chucks were used, SDS chucks are used here. No ordinary drill bits can be used. only special drill bits with the appropriate shank can be used. It must have 4 slots, which in pairs have different diameters, they are needed to hold the tool.

To install conventional drills in the SDS-chuck, you can install an adapter for a cam chuck, but in this case it will not be possible to achieve high quality drilling because of runout.

It is also worth noting that there are two types of shanks and chucks:

For 4 slots. SDS-plus, holds tooling up to 26 mm in diameter. For 5 cuts. SDS-max, drills with a diameter of more than 20 mm.

Is it possible with an electric screwdriver to drill a hole in concrete

If you do not have special tools on hand, then an electric screwdriver is used for drilling concrete. However, attempts lead to the fact that it is not possible to achieve a positive result. It is connected with the fact that in an electric screwdriver there is no function of percussive drilling, so it is contraindicated to use it for work with concrete. An electric screwdriver is designed to work with self-drilling screws, but it is also capable of drilling through wood. Only it is necessary to take into account that screwdrivers are based on a low-powered electric motor. If the motor will experience maximum loads, it can simply burn out.

If you are going to drill through thick wood with an electric screwdriver with a 10 mm drill bit, then give up the idea right away. Especially do not use the tool for drilling in concrete or mixing. You can’t drill through concrete with an electric screwdriver, because this device doesn’t have an impact mode. It is also not recommended to mix loose mixtures by attaching a mixer attachment to the chuck. The motor will experience high loads (and it has very little torque), and therefore can burn out very quickly.

This is interesting! Each tool has its own purpose, so before using a particular device, you should read the instructions.
