Shock drills differ in price, capacity and destination, and when choosing it is worth considering all 3 factors. Of course, you can buy the most powerful tool, but professional models are more narrowly placed, and you can't call the universal drill. Therefore, to perform domestic affairs, if you do not plan to drive a large number of holes every day, the amateur medium-air tool is quite suitable.

Choose a drill is difficult: many types, the mass of features, the sea of \u200b\u200btechnical characteristics. If you do not want to spend your money, then you will have to delve into everything. I am sure, together we will cope with, the benefit of some consumer tricks we have already worked.

How drill tempered

Any wizard will say that the drill is the most important tool. With this, even those specialists-builders who do not use (seemingly) do not use, although in fact some mixers, and electric screwdrivers, and the screwdrivers in many producers are called drills. Even perforators can be calmly considered direct relatives of machines for drilling holes. Manual drills, working on muscular strength (at least their real prototypes), are known somewhere from the Renaissance, and the simplest devices for drilling work are already applied for several thousand years and occupy their honorable places in many archaeological museums of the world.

Mechanisize, or rather, electrifying the process (steam drives already occurred) succeeded at the end of the 19th century, then more or less compact electromotors appeared, once again overwhelmed the world. In 1889, Arthur James Arnot (the future employee of Black & Decker) from Melbourne for the first time handed the electric energy to the drill, faced the task of optimizing the process of drilling stone and coal - so to speak, industrial option. In 1895, the Karl brothers and Wilhelm Fine from Stuttgart were distinguished. They managed to create a drill, which can be kept in the hands - a construction and consumer option. In two years, AEG has released a first serial machine, similar to modern analogues. Further, almost nothing has changed, work was carried out only on the improvement of the drill - ergonomics, productivity, safety, additional functions.

The first electric drill of Fijen, 1895

Now the drill is, probably, every man, well, at least, almost all of us at least once, but thought about her acquisition. In any country of the world, this is the best-selling tool. Narland recognition is not at all by chance. Drill allows you to drill a variety of materials, drill with a blow, screw the fasteners, clean and grind the surfaces, mix inhomogeneous solutions, cut into the thread. Some manufacturers offer a lot of special nozzles that make it possible to apply drill as a jigsaw, milling mill, a planer ... a very controversial utility of such functionality, but it is the possibility itself, and it warms it.

If earlier in our country, the drill needed to "get out", now it is worth just going to any specialized store or market, and you will simply appear to be a huge assortment. Models and whole classes so much that not only lovers of tiny at home can get confused in the instrumental diversity, but also the Matte Masters - demand gives rise to a sentence. Our common task to figure out all the nuances of electric drills, make the process of choice as conscious and comfortable.

What is a household drill

Many are asked about the "professional benefits" of a household instrument. What is this cars, which are many times cheaper than their older brothers? What is the difference? What are they intended for? Why are companies with almost space technologies make simplified options for their products? Everything is extremely simple: not everyone needs a drill to work around the clock, there are few people who have peacefully in the storage room / in the garage until you need to impair the picture or repair a stool urgently. Here for a home master and created cars of the Hobby class. It is not worth considering cheap Chinese brands and frank fakes - often it is unsuitable for work and unsafe tool. And, on the contrary, domestic aggregates (some specialists rely climb them to everyday) also not from this series - they are quite competitive in commercial use. Amateur class is a special line of instrument or products of individual divisions of solid global firms that are ready and able to make a special consumer a special offer (in the section "Price / Quality / Functionality").

It may seem that the company "dear" professional specimens, but it is not quite the case, they create absolutely other cars. The main feature of the household drill is that it is possible to exploit them not more than 4 hours a day, according to the "one to one" scheme (fifteen / twenty minutes we work, as much rest). Why is that? There is usually a simple design, less persistent materials, weaker engines. Professional drills have more powerful motor, wear-resistant parts, better protection against aggressive effects (dust, moisture, vibration). What gives us in return for the developers of household drills, except for a favorable price:

1. Extended functionality - as an illustration, a shock tool, and even with a reverse (drill, drill, spin), for example, give Bosch PSB 500 Re. Professional cars have a much narrower specialization.
2. Good ergonomics. We have low weight due to the use of less powerful motors, lack of metal gear of gearbox, lightweight parts. The case is replete with soft inserts and lining. The machine is supplied with a quick-inside cartridge. Original product design (Black & Decker KR753).
3. Protection against an inexperienced user. Power characteristics are limited, and the safety of the operator is improved.
4. Wide equipment. In the suitcase, you can detect the set roller, spare cartridge, a bit holder.
5. Large warranty period. Some manufacturers offer 2 years, instead of one, as for professional models.

Next, we have repeatedly remember the separation of drills on the "pro / hobby", but as long as we summarize said. The household instrument definitely has the right to exist, it will perfectly cope with all the tasks, provided that the loads are moderate. Commercial or amateur assignment of a specific drill is always indicated in the passport. Another trouble-free sign is the time of continuous work of a professional drill (at least 45 minutes), it should also withstand a working shift at least 7-8 hours.

Special destination drills

Drill is a multifunctional tool in principle, but for a comfortable execution of specific tasks, some models are characterized by a special design, a set of peculiar characteristics. Let's look at them in more detail.

Hammer drill

Drill with a blow can help borrow in a slight concrete or brickwork, for work on soft materials, the function is turned off. Immediately say, this is not a perforator: the power of impact here is ten times less (Jouley do not even indicate in the manual) and the principle of operation of the beating mechanism of the other. In the shock drill, the main work makes a ratchet, consisting of their gear couplings, which are disconnected during the load (one of them rolls on the other) and the shaft is moving progressively.

In the perforator, the blow is obtained from the work of a special "drunk" bearing and pneumatic elements. If the drilling function for the perforator is the main one, then the drill shock mode is just an auxiliary function. First, it can only take a light concrete and brick, and, secondly, it serves such a mechanism very short time, thirdly, other tool parameters suffer a little (the mass increases, there is spindle hopes, the accuracy of unstressed drilling is worse).

The drill strike strength and its resource directly depends on the force of pressure tool, from the strength and geometric characteristics of the gear, from the location of the ratchet (the farther from the cartridge is the weaker drilling).

So, the shock drill is a good solution for rare drill works "10 minutes per year", amateur option. These aggregates will in no way be able to replace the perforator, while the known universality will have to pay a decrease in some standard characteristics. There is no rules without exception, drill drills can be found in professional rules (Bosch GSB 16 Re, Makita HP2071).

Drill for screwing fasteners

Working with fastener is one of the most important functions of the drill, in the cartridge of any of them you can clamp a bit and twist the screws, but some machines are adapted for this better than others:

1. The presence of a reverse is a very important point, since the screws periodically have to get out during work, fortunately, this function is available in almost all modern tremers.
2. Changeable speed. It is impossible to work with high speed screws - it is necessary to drop. There are preset options, a sensitive button, a multi-position gearbox (several speeds) applies.
3. Pulse mode (short-term shocks). It is good for dismantling consumables.
4. Removable cartridge sometimes allows you to install the shank bits directly to the spindle (Kress 650 BS). The dimensions of the machine are reduced, its weight is reduced.
5. Adjusting twisting force. A similar function is considered very specific, it is characteristic of a tool that is highlighted in a special class (screwdriver). Read more about rechargeable screws in the article "How to choose a battery screwdriver."

Perhaps, it is worth mentioning about screwdrivers with automatic cassette feed of self-tapping screws, a very convenient device with large-scale fasteners (for example, Makita 6844).

Drill mixer

Many drills (if not to talk about "clean" mixers with a chuck's cartridge) with a capacity of 1000 watts capable of mixing viscous solutions. For such works, they are often combined with elongated additional and D-shaped main handles (Makita 6300-4). In addition, powerful drills have a multi-speed gearbox that allows you to reduce the transmission with increasing torque (Bosch GRW 11 E). The high power of such machines and the presence of several protection systems allow you to install large snaps in them: dried a large diameter, crowns (including diamond drilling). Many such drills have a discontinuous coupling that protects the employee and the machine from damage in case of jamming (Makita DBM080).

Bosch GRW 11 E

Corner drill

These are usually light compact machines designed to work in hard-to-reach places. They are supplied with an angular gearbox, so the spindle and the equipment is located to the axis of the case at a right angle (both in the UCh), for example, Makita DA3011F. In the rest - no particular differences in the corner drill does not have, well, except that only their power is mostly low and the shock function can not be. A real alternative for a highly specialized angular drill is angular nozzles for standard models that allow you to solve special tasks.

Makita DA3011F.

Choose drill right

Power characteristics

On average, the drill power is within 500-900 watts, stronger cars also exist, but their diet is a very large drilling or kneading of viscous solutions (Metabo B32 / 3 - 1.8 kW). We always mention that the excess motor power affects the dimensions and weight of the product, but in the case of the drill, these moments are not as critical, unless of course it is purchased as a screwdriver. Only a fairly powerful power plant will be able to provide the required torque, the supply of which is simply necessary for drilling large and deep holes for frequent manipulations with durable materials.

Spindle speed. In passports, the nominal speed at idle is indicated than it is more, the cleaner is the hole and more opportunities for a low-power tool (such a scheme is often used in household models). Also, there is also a high speed. It makes sense to pick up for a drill, and if the device is periodically used for grinding / polishing. For work with fasteners - the high speed of rotation is not needed (400-500 rpm will fit), so it is necessary to check the performance of the speed regulators.

Power / frequency / torque indicators are tightly interrelated: when one of them changes, others are inevitably change - you need to choose in the complex. And even better concentrate on the maximum diameters of the snap-in for various materials, these characteristics are much more eloquent about the instrument.

Constructive features and auxiliary drills systems

Reverse It makes it possible to unscrew the fasten and release the jammed snap. The checkbox, through the button or rotation of the brush block 90 ° (Metabo UHE 2850) relative to the collector (allows you to save the power during reverse movement) the inclusion of the electric motor changes. A good reverse is located at hand and is easily translated into different positions, but even better if it is associated with the start button so that there is no switching option when the engine is running. The ideal reverse ensures an equal force of rotation in both directions (usually the movement of the outlet is much weaker).

Multiposition reducer Designed to reduce transmission and increase torque. The first speed is a small frequency and a high moment, the second / third speed is a big frequency and a small traction. Obviously, cars with such a design are much more functional than the rest, since when switching speeds, output power does not change (Makita HP 2070).

Cartridge characteristics. In essence, there are two types of cartridges: key and quick-release. The first type to change the equipment will require the use of a special key, but it does not carefully consider it more reliable, so used for powerful devices and shock drills.

Logging cartridges (BZP) are driven by hand only, there is no additional tool here. A quick-swampling cartridge with one coupling is delayed with one hand, you can do it even in gloves, applies only with a spindle lock mechanism (button or automatically), for example, as in the Kress 850 SB-2 model. Two hands should be twisted with two hands. BZP - the thing is very convenient (no need to constantly look for an elusive key and adapt to the cord, the hands are not injured about the rifle of the progressive mechanism), but sometimes users have complaints about their reliability and durability. High-quality fast-mode cartridges are decent money, and sooner or later the cartridge has to be changed.

It is worth paying special attention to the maximum fitting diameter of the cartridge. The minimum is usually not limited (sometimes cams converge almost to zero, more often up to 1.5 mm), but the upper limit is always. It is traditionally 10, 13 or 16 mm. Naturally, such restrictions depend on the power characteristics of the machine and they are subordinate to them. The "dozen" cartridge is put on a lightweight tool, the 16th drill will pull only a powerful drill, 13 - diameter of middle peasants.

Metal casing gearbox Directly indicates the belonging of the tool to the professional class. Thanks to this execution, it is better to get warm from moving parts, a high stability of the node is ensured, although the mass of the drill increases inevitably.

Electronic speed adjustment. This is something else than rearrangement of gearboxes. In this case, using a thyristor or a rheostat. Full-wavelength adjustment is ensured by the degree of clicking on the sensitive start key, it is stronger than davim - above speed. The speed of rotation can be set step, for this, a special wheel is used (Hitachi D10VC2) or the slider switch - this control body is usually taken out to the case.

Note that when performing electronic adjustment, we limit the output power of the tool, which does not occur during the mechanical preset.

Advanced models possess frequency maintenance system under load (Constant electronics), so that the machine tracks the load and supports the specified parameters due to the power reserves of the motor. It turns out that we can not only clearly adjust the tool for a specific material, but also to avoid jamming with a sharp change in the density or increasing the pressure of the pressure (AEG SB 22 2E).

High tech drills have temperature sensors of windingsThat eliminates the possibility of damage to the motor during overloads. In critical cases, an automatic power off occurs, or the LED indication is triggered.

For powerful drills, it will be very relevant system "Smooth Start"which slowly accelerates snap to optimal revolutions (it is easier to start drilling exactly by a mark), excluding starting jerks (increases the durability of the transmission elements) and the overload of electrical networks (AEG SB2E 1200 RST).

Pulse work drill Helps unscrew the accurate fastening, start drilling without incitement, "defeat" too hard material. Interestingly, such a system is running on the principle of the load jump, as at starting currents (Metabo SBE 900 Impuls). Judging this function within reasonable limits will solve a number of complex tasks, but it is worth understanding that in this mode the tool works extremely, the wear of the most important nodes increases.

Another point is an opportunity fixing the power button in the on state (Sparky Bur 150Cet). What does it give? First, while working, you manage to let go of the key and change the grip tool, just relax your hand. Secondly, only such drills can be installed inpatient on a tripod or in a magnetic rack (Metabo B 7532/4), it turns out a light drilling machine.

The most important little things

• Choosing a specific model, just just understand the technical characteristics of the instrument, you need to find your own, most convenient.
• We always recommend thoroughly "shake" the car in your hands, paying special attention to the configuration and type of handles, both basic and auxiliary. Someone will like thin sticks, someone more voluminous. Purchase overlays, better if they have a corrugation and a non-slip surface.
• Try verself to beweling a drill, there are very interesting options in this regard, for example, with a shifted pistol handle (DWD215G).
• Be sure to appreciate the availability of all controls, their informativeness and switching light.
• Take a look at the length of the power cord and the material from which it is made. Soft long cable will significantly increase comfort when operating "at place".
• Check how well the cartridge holds the drill, as simple / difficult it changes, which is its real minimum and maximum (drill diameter).
• Speak the car for spindle backdrop.
• Run a drill in different modes, try to determine the possible beats, noises, power loss under load.
• Pay attention to the possibility of stationary installation. Usually the size of the landing place in the tripod is 43 mm in diameter.
• Compare a complete set of competitors. Case, rolled, metal depth limiter, spare patron - all these things, if they are branded (!), There are a lot.

Once again I would like to say, choose the tool based on the projected loads. Make the emphasis on the maximum allowable snap size. Do not chase for additional approaches "to be". Keep in mind that it does not break in the instrument only that part that is not in the design.

Drill - A tool focused on performing a whole complex of tasks. Drilling holes, twisting of nuts, mixing liquids of different consistency - only a small part of the cases that can be trusted without fear. That is why the question is which shock drill to choose all those who are accustomed to repair and finishing work to rely solely on their own experience and knowledge. So, what should be taken into account when purchasing this indispensable assistant?

Shock drill: Benefits

The construction market offers today a large selection of electric drills. Schurpevover Drill, Corner, Drill Mixer, Drill Perfederator ... To be lost in such a variety. However, the shock drill, which is the main object of this article, is beneficial from the listed samples. Than? Let's deal with.

Hammer drill - Universal fixture. The main difference is a special mechanism of drill movement, which makes not only rotational, but also reciprocating movements. This advantage of the drill mechanism allows you to work with any materials: wood, metal, plastic, brick, concrete.

But this is not the only plus. The best shock drills are high-power devices used for:

• cutting threads in metal;
• screwing and unscrewing screws;
• drilling wood, metal, natural stone;
• doing holes in concrete and brick.

How to choose a shock drill?

The choice of a shock drill, which will fulfill the task with honor with honor, suggests, first of all, the presence of theoretical knowledge. It is impossible to choose a tool without having an idea of \u200b\u200bwhich items it consists.

"Heart" drill is engine. Power may vary from 400 to 1500 W.

It is important!
The power of two-speed models is more than 700 W.

A wide range of motors provides the ability to choose the best for each option. I am glad that the branded producers put the production of compact, but productive engines.

Shock drills are supplied reducer(one or two-speed). The second, of course, is better because The limit of the spinning moment is more. Note that the higher the numerical expression of the gearbox, the easier it is to work with ring cutters and screws. High-speed specimens are distinguished by a small limit of a spinning moment, although during their homework, this minor minus will not bring inconvenience.

The "Start" button is designed to adjust the number of revolutions. During the operation, change the specified parameters is not possible - the knob (wheel) is combined with a switch. On the left below, the speed switch is usually located above - the shock function switch. The handle of high-quality drill is supplied with rubber overlays that reduce the level of vibration and improving comfort when using the instrument.

Reverse Rotation Option (Reverse)there is almost every modern model. It is necessary for crushing the drill and unscrewing screws. Another useful feature - Protection against overload. For example, if the drill unexpectedly embarrass, the protective mechanism will stop the tool, the gearbox will also save the gearbox from failure.

Sometimes the shock drill is complemented Quick-minded or toothed patron. To fix the first additional devices, you will not need, but when consuming the second without a special key, it is not necessary. Equally important is it length of cable. Too long will be confused and interfered, too short - to skip movement. The optimal option is 4 meters.

So, the general idea of \u200b\u200bhow the shock drill works is obtained, which means that you can proceed to the review of popular models.

Characteristics of the most popular models

Multifunctional drills models so much that even "advanced" builders involuntarily think about the question - what a shock drill is better? On the advantages of a brand - below.

Shock Drill Bosch.

Rated power - 1010 W. Comes with quick-chase cartridges, have a reverse, the choice of the number of revolutions. Electronic control. Particularly interesting is the GSB 13 Reer - an excellent professional model characterized by slight weight and accuracy. The process of replacing the drill is simplified - it can be done by one movement of the hand, and the option of the exact start of drilling allows you to do without inclination. The number of revolutions is installed by means of adjusting wheels. A comfortable handle helps easy, fast and most comfortable work.

Drill Impact Makita

No less demanded solution of diverse tasks. Virtuoso copes with the drilling of holes in the metal, concrete, stone. The rotational speed is set by a switch equipped with the lock key. The thoughtful design of the reverse not only helps to quickly change the direction of rotation, but also prolongs the life of the device 2 times. The side handle can be fixed in any position. Complemented by a depth gauge.

Drill shock intercope

It has a lot of advantages. One of the main - acceptable cost. The average price range is 90 dollars. The power consumption of the key cartridge is up to 1000 W, weighs a little more than 2 kg and makes about 2500 revolutions at idle. Drilling diameter - 16-40 mm (depending on the characteristics of the material).

Dewalt drills

A large system of service options and high reliability allow you to use the shock drills of this manufacturer for long-term work time. Cable length - 4 meters. The side handle can rotate 360 \u200b\u200bdegrees. The two-speed gearbox is configured to carry out quiet and smooth drilling. The high torque will facilitate the unscrewing of the "accurate" screws and bolts. The developers even took into account the dimensions of the juro - it is increased, which facilitates pressing with two fingers, as well as work in thick gloves.

Hitachi shock drill

The electric drills from the Japanese manufacturer received recognition due to the high quality of execution. Basic advantages - enviable performance, comfortable design, durable case and excellent specifications. In a word, if you are looking for an assistant, tested, then the drill is Hitaci - what is needed.

Drink Protool

General properties: cast body, thoughtful form, the presence of an additional handle, a device for wrapping and centered. Almost every model is equipped with a safety friction clutch. The package includes a convenient storage and transportation suitcase.

First of all, you should decide on the volume of tasks, to execute the tool. Pay close attention to the main characteristics. Devices with high speed make smooth, neat holes.

It is important!
For household use, there is enough drill that makes up to 2900 revolutions per minute.

Do not miss the question of ergonomics and vibration protection. The battery must be capacious, because it depends on this time. Many professional drills are produced with two batteries: one - works, the second is charging. If the recharging of the household model will be required from 3 to 7 hours, then a professional drill will be ready to work maximum in an hour.

Now you know what criteria to navigate when choosing a shock drill, which means you can easily buy a good, high-quality device for all occasions.

Using a drill form holes, disassembly disassemble, screw the fasteners, mix solutions, produce other construction operations. The nature of the work depends on the nozzle and technical capabilities of the tool model. The article is devoted to drills with a shock mechanism.

Main characteristics

Drill in shock drills makes rotational and reciprocating movements, which allows you to make holes in almost any material. This functional feature brings the tool with the perforator.

The principle of operation is based on drilling, while for the perforator is characterized by dumping. This is their main difference.

The shock drill is acquired if the power of ordinary drilling equipment is not enough or requires the processing of solid surfaces in which it is difficult to form a hole.

Design elements

The basis of the tool - the engine with a power of 400-1500 W. Two-speed electric drills are usually supplied with a 50 W engine and more.

Equipment with a powerful productive engine is often compact.

The network shock drill is completed with a gearbox, one or two-speed. Two-speed models have an enlarged torque limit. In high-speed indicators below, but at home work, this feature does not bring inconvenience.

Reverse (reverse movement) allows you to separate the drill, unscrew the screws. The option is almost in all professional models.

Protection against overload does not allow to fail the motor and reducer at the time of jamming the drill. Need to safely operate power tools.

On a drill with a blow can be installed quick-swamp and gear cartridge. In the first case, additional fixtures are required. The fastening of the gear is performed by a special key.

Selecting the unit, you need to navigate the length of the cable.

Optimulated four-meter cord.

The household always has classes for the wizard. Watch the wall picture, install a magnetic lock in the locker, stretch the antenna cable. In the course of all these works, smooth holes in the tree, drywall or plastic need to drill. Electric drills came to replace the manual coofer: the holes are made quickly and accurately. In addition to drilling, modern power tools can accumulate, grind and polish materials. How to choose an appropriate drill for home and snap for it?

Indispensable House Tool - Electric Drill

Device

The electric drill is a housing with a handle in which the electric motor is installed. Gears reduced gear reduces motor rotation speed. On the gearbox axis, a cartridge is installed in which the working tool is clamped. The drill or nozzle rotates and processes the material.

The base of the drill is a rotating shaft. Additional devices convert a drill to a drilling, grinding or lathe.

What work does the tool perform

Drill performs the following functions:

• Drilling holes in a tree, plastic, metal, glass with various rolling.
• Grinding surfaces by abrasive nozzles.
• Drilling with dumping holes in soft building materials (brick, aerated concrete).
• Tree cutting and thin metal with cutting discs.
• Sharpening knives, axes and braids abrasive discs.
• Single mixtures with a mixer-mixer enshrined in the cartridge.

The shops have a wide selection of tools and drill tools: dried on wood, metal and concrete, grinding and cutting discs, borants and mixers, circleuris and crowns.

It is interesting. For poultry farms there is a nozzle that helps draw the chicken carcasses.

Additional equipment

Additional equipment - racks, supports and clamps expand the possibilities of drill and even turn it into the machine.

Drill, reinforced in the clamp with a bed - it turns out a drilling machine. The handle smoothly supplies a tool to the material.

The rack into which the drill body is clamping, provides drilling holes at any given angle - perfectly direct, or sharp.

The drill differs from the perforator

Almost all modern electric drills have drilling mode with a blow (shock drill). This mode facilitates the drilling of brick, a loose stone or foam concrete. However, coming up with a puncher in the processing of concrete, the drill is not in a state. The drill strength does not exceed the tenths of Joule, while the perforator is calculated by units and dozens of joule.

The principle of operation of the shock drill is the slip-up of the gear under the load, which is why they jump together, creating a move along the axis of the drill. Perforator is a pneumatic tool in which the blow produces air pressure.

What are the drills?

Professional and domestic

Like another power tool, the drills are divided into two large class - professional and domestic.

Professional drills are required to work for hours without a break, they are made as comfortable as possible for long work, durable materials are used in the design. The cost of such drills is several times higher than household.

Household drills are made of less durable materials, gear gears may well be plastic, and a small motor forced. Weigh the tool less, but work with it must be interrupted every 15 minutes - overheat.

In the household, the drill does not work all day, so it makes sense to overpay for a professional tool.

Unstressed and shock

The simplest drill has one mode of operation - the cartridge with the drill fixed in it rotates, the drill forms a hole in the material. This mode is the main for 90% of the tasks solved at home or in the country. Such drills are called unstable, their share accounts for 20% of all the devices sold.

To increase the attractiveness of household instruments, manufacturers have included another mode of operation - shock. When you click on the tool, the drill makes not only rotational, but also reciprocating movements. 80% of household drills are shifted into the shock mode, but the use of it is small. The translational movement of the drill will help only when driving light building materials.

If you plan to drill monolithic walls, it is recommended to pay attention to the perforator.

Network or accumulative

If the drill motor is powered by an electrical network, then the master is tied to the outlet. The radius of the working area of \u200b\u200bthe tool determines the network cable and existing extension cords. Drill the column of the country gate or output the wire from the apartment shield is not always easy to work. But, the network drill always issues a predetermined power on the drill, which does not depend on batteries.

Network drill is tied to a socket

Rechargeable drills give the owner an additional degree of freedom. Attach the loop to the garage goal or polling the welded seam on the doors is not difficult. The reverse side of the convenience - batteries that need to be charged. The discharged tool is reluctant, the drill rotates slowly and stuck. Batteries live no more than three years, lose the tank and deteriorate.

The variety of drills is screwdrivers. Network and rechargeable are manufactured. In them, a special gearbox lowers speed and increases the torque of the tool. A 100 mm long screw is rolled into a pine timber for half a minute. Adjustable coupling will stop the rotation when the screw is twisted until it stops.

Selection criteria for home use

Power

The power of the modern electric runlets changes from 500 to 1500 W. This important parameter determines the torque tool and the ability to process dense materials. The weak motor will not verify the drill in steel, the grinding circle is stuck in the birch plywood. The more power, the more the weight of the tool. For homework, it is recommended to choose a drill with a motor 700-800 W.

Rotation frequency of Vala

The speed of rotation of the engine varies from 2000 to 4000 revolutions per minute. For each drill, the manufacturer selects the optimal speed of rotation (it is called nominal and indicated in the characteristics of the model). The higher the speed, the longer the number of times the drill passes by material, giving a cleaner surface. On large revolutions, the risk of mistakes increases - the hand shook, the drill went aside, spoiling the workpiece.

Smooth speed adjustment is an important function of an electric drill. At the beginning of drilling on small revolutions, the drill will not lead, the hole will come out exactly in the right place.

Diameter of drilling

The parameter "drilling diameter" determines the largest hole in size, which triggers drill in different materials. Obviously, the density tree is very different from steel, so the manufacturer sets the maximum hole diameter for its product and separately in steel. If the drill has a shock mode, the diameter in concrete is also normalized.

What is the smallest hole you can drill a drill? It depends on the cartridge, usually dried less than 0.5 mm no longer secured. For the microbril, there are special cartridges with collet clamps.

Type of cartridge

The cartridges in which the tool is clamped are two types: with key and quick-release.

The key cartridge is known for a long time - in it cams are compressed using a toothed nut rotated by a special key. Advantages: Reliable retention of drill even in the most difficult conditions of work. Disadvantage: Change of drill takes a minute, the key is easy to lose.

In recent years, high-speed cartridges have appeared. In them, the clamping nut turns his hand. The advantages and disadvantages are opposite to the key cartridge - the tool is changing over ten seconds, but the hands of the hands do not always have enough for a solid clamp, for example, at the outlet of the metal drill clinics, the shank slipches in the cartridge.

Equipment

The simplest equipment consists of one item - the drill itself. If the manufacturer offers additional items - this is a big plus. The kit may include:

• The suitcase is a wonderful packaging for storage and transportation. The tool and accessories are neatly laid and not dust.
• A set of tool - a basic set of most popular rolling on wood, metal or concrete.
• Laser level - attached to the shock drill, needed for marking wall holes.
• Nozzle with nut - clamping grinding and cutting discs.
• Additional handle - screwed to the body, for her master keeps the tool with a second hand, for example, when drilling concrete.
• The depth limiter - the pin-screwed pin with the ruler, will not give the drill to immerse themselves further than died.
• Spare brushes. The collector engine is powered by mobile contacts - coal brushes. This item is overtaken with time. Well, if the manufacturer has prepared a replacement.

It was noted that in recent years, manufacturers began to save on the configuration of drills, especially inexpensive.

Additional functions

Engineers are implemented in electrical drills additional features that make the work convenient and safe. The most important possibilities:

• Smooth start. The collector motor starts in a short circuit mode, which generates current throwing on the network, the collector brushes are sprinkled. The regulator smoothly increases the speed of rotation to the maximum, the tool will serve longer.
• Automatic revolution controller. The electronic circuit supports the constant speed of rotation of the drill regardless of the applied load. The drill is equally smoothly handles wood and metal.
• Fixing switch. If the drill works with grinding or machine, the motor must work constantly. The button lock releases the hands of the wizard.
• Reverse engine. A convenient feature will help if the drill at the outlet of the metal jammed. The master closes the lever, the direction of rotation of the drill changes to the opposite (reverse) - the tool is released.
• Cartridge brake. When the master takes off the finger from the start button, the cartridge continues to rotate in the inertia, touch it is dangerous. The braking system instantly stops the rotation of the cartridge after turning off the engine.

Other important criteria

Choosing an electric drill, take it in hand. A good drill handle is equipped with rubber strokes and comfortably falls into the palm. Buttons and switches are pressed easily, the cartridge rotates softly, no longer hangs in the longitudinal direction.
