The difference between a shock drill and an electric screwdriver. What are they

What is the difference between an electric screwdriver and a drill. a key difference between them

Electric screwdriver. a pistol.shaped manual power tool for twisting / unscrewing screws, screws, screws and other threaded marking with slotted and hexagonal heads. It is used in everyday life and in the production for installation / dismantling furniture, fences, roofs (roofs). In the presence of special equipment, surfaces are polished and holes are drilled. It works on an electric network or battery. some versions (pneumatic) function in compressed air. The device as a whole consists of a case, fasteners, mechanical and electric parts, as well as adjustment and protection systems. Basic structural elements:

  • plastic or metal case with a rubberized handle;
  • rotating an electric (pneumatic) engine;
  • Planetary gearbox: creates a transmission from motor to a spindle with a clamping cartridge;
  • adjusting clutch adjacent to the gearbox;
  • clip cartridge for fixing nozzles;
  • electronic BU with a start button and a reverse switch;
  • Battery: present only in the same models.

Previously, a bat is inserted into the cartridge and fixed with a 6-sled shank; The clutch is exhibited (exists from 8 to 25 positions); Network electric screwdriver, unlike the battery, is connected to the outlet. When you press the start button, the engine starts, which, through the planetary gearbox, begins to rotate the spindle with a cartridge and a bat. the stronger the effort, the higher the speed. After twisting the screw, the resistance of rotation increases, as a result of the rattle, slipping, and the transmission stops. When twisting the meters, a reverse is turned on. the equipment begins to work counterclockwise.

Definition

To find the differences in the drill from the screwdriver, it is necessary to consider them in detail. These tools have external similarities, but have a huge number of structural and functional differences. The principle of operation is also different. In the article we will figure out what is the difference between an electric screwdriver and a drill.

Drill

A drill is a manual electrical device made in the shape of a gun. It is used to drill holes in the blanks of wood, metal, brick, plastic or concrete (iron-concrete structures).

Most often, the drill is used during construction work or repair of premises in industrial or home conditions.

Modern models of tools have additional functionality. For example, with their help you can grind the surface, use it as an angular grinder or construction mixer.

The design of the drill consists of the following elements:

  • A case made of plastic or aluminum with a rubberized handle and an additional handle;
  • A collector engine with a rotor, starter, anchor and brushes;
  • Fast.sounding cartridge (used to hold the nozzle);
  • The start button fixed in a certain position during a long.term work;
  • Handle for regulation of speeds (it should be adjusted in accordance with the processed material);
  • Power cord for connecting to a socket;
  • Metal limiter (made in the form of a rod, necessary to control the depth of holes);
  • LED backlight for accuracy.

Before starting the tasks, you should set a depth limiter in the desired position, as well as set up speed. This is done depending on the structure of the material (the firmly the workpiece, the less revolutions are required).

Then you need to take the tool by the handle and press the start button. Be sure to direct the nozzle along the same axis that should be at the hole in the material. Changing the angle is prohibited. From the spindle, torsion is transmitted to the gearbox, which allows the drill to enter the prepared surface. Most of the drills develop a fairly high speed, so all work should be done carefully.

Important! While working with a drill, it is recommended to use protective glasses. Otherwise, small particles of construction dust can get into the eyes and damage vision.

Electric screwdriver

Shurovyrt is a hand tool made in the form of a pistol. It is intended for unscrewing or twisting of screws, screws, screws, as well as other margins with a thread with hexagonal or slotted heads.

It is often used at home and at production. Using a screwdriver, it is convenient to mount or dismantle furniture, roof, fences.

If a special nozzle is included with the tool, then it is also used to grind surfaces and drill holes, thereby the manufacturer connected the drill and electric screwdriver in one tool. Shurovyrt can work from a socket or battery. Separate models function in compressed air (pneumatics). The design of the tool consists of a case, mounting unit, electric and mechanical part, as well as a protection and adjustment system.

The components of the design of the screwdriver:

  • A case made of metal or plastic with a rubberized handle;
  • An electric (or gas) engine that turns the nozzles;
  • Planetary gearbox (performs transmission from motor to spindle with a clamp);
  • Clutch for adjustment, which is associated with the cartridge;
  • Clip cartridge (holds at the site of the nozzle);
  • Electronic BU (on it there is a reverse switch and launch button);
  • Battery.

Which is better: drill electric screwdriver or drill, and what are their differences

The question of a drill or drill-electrical screwdriver is more complicated, but not critical. The usual drill (OD) as a place of installation of a working tool includes a universal cartridge. Drill-electrical screwdriver (DS) can have both a replaced cartridge and universal cartridge, for drills and bats.

The difference between a drill and an electric screwdriver in the appearance is almost absent: the output of the power wire, a plastic or metal case in the form of a massive pistol, rubberized handle and overlays, control buttons.The configuration may have a depth limiter and a flashlight. Weigh approximately the same.

Directly the difference is in the form of a cartridge:

  • OD has its classic structure. 3 or more zang, clamping the tip of the drill with a diameter in a wide range or tail;
  • DS will be equipped with either a fast.sounding cartridge (universal. for bits and drill) or hexagonal (only for bits).

Which drill an electric screwdriver to choose and what to pay attention to

There are several signs by which it is possible and should be selected.

What to choose and how among drums (DS)? Key parameters: appearance, functionality and the presence of certain modes, the possibility of setting and controls.

ergonomics

The best job is when it is convenient and comfortable. Therefore, the ergonomics of the DSH is one of the first factors in the selection. Already when taking it in hand, it will become clear whether it is easy to hold a tool with a hand and whether it is possible to reach the required buttons with one hand.

The shape should be streamlined if possible, the color is bright for quick search and easy determination of damage to the body and handle. The design of the pistol type can be both classic and with a slightly shifted handle (the angular arrangement of the cartridge is purely individual and not universal). Electric screwdriver battery is the most ergonomic.

The handle can be tilted or at right angles, a battery is placed under it. The balance is visible only with the established change of nozzle. The retention is reinforced by the surface of the handle. the rubberized or rough surface will facilitate the effort to create friction.

Brighting engine

The main feature of this type of DS in the engine without brushes (Beskollector type). The brushes that are out of order, which serve to switch electric current, are replaced by an electronic control unit.

Brightless engine has the following list of pluses and minuses.

  • simple adjustment of rotation and change in a wide range;
  • lack of brushes and the need for their regular replacement, prolonged functioning;
  • efficiency and high efficiency;
  • lack of sparking and functioning in conditions of dust and in mixtures of explosive gases;
  • reduced dimensions and mass;

When food from the battery, the service life of a bullying DS will be higher. With all the advantages, limited budget often makes such models bypass.

A cartridge of electric screwdriver

There are several types of cartridge, each of which is well suited for a certain specificity.

  • Fast.minded (BZP). a classic structure (spindle, sleeve, tsangi), the key is not required: the most wear.resistant and reliable, for drills with a round shank you need an effort, more ordinary;
  • self-loading or SDS-patron-even a muscular force does not need for tightening: the tool will cope with the work with a quick change of nozzles by means of the design of balls holding the shank for deepening in it;
  • Hexagonal-perfectly for bits as a nozzle with an appropriate shank: successful for screwdrivers, mini-fires, drill;
  • bit patron-a cartridge for bit: it is needed to remove (turning away) fasteners, most convenient at home.

The cartridge captures the working body, the form and purpose of which can be different. up to such a solution as a pump for a drill or even a jigsaw.

Rotation speed adjustment

The speed of rotation of the working tool is performed manually or automatically.

Manual setting is performed mechanically. On the case, there must be control organs for this. a button or switch, after working with which the speed of rotation changes. This is relevant for DS with a capacity of 18 in.

Automatic adjustment is carried out through the work of the built.in processor. The signal received from the regulator or toggle switch enters the processor. He, in turn, sets the engine operation and the required rotation speed.

Adjustment is also found by pressing the start button. The bottom line is that the stronger to burn the button, the faster the number of revolutions will be. At the same time, both the strength and the depth of the button pushing are played. The power supplied to the spindle and the working tool will grow directly in proportion to them.

Shock mode

The shock mode is not the main one for DS. Therefore, without the need to overpay for additional unnecessary equipment to nothing. an unstressed apparatus is enough for twisting. Determine the conditions of use and targeted materials.

The essence of the shock regime is that the usual rotation is supplemented by reciprocating movements in the direction of the rotation axis. A special mechanism from high.strength materials provides an advance. creating a high number of shocks per unit of time. Thanks to this, it becomes possible not only to tighten the metizes, but also to create holes in solid materials. stone and concrete.

The benefits of shock models of DSH is compact, which allows you to refuse in some cases a separate shock drill, replacing one electric screwdriver. The mode does not affect the diameter of the cartridge.

engine brake

One of the most popular additional functions is the ability to stop the engine. The value when choosing a tool with the brake function is that when twisting screws or screws, the moment often occurs when the further movement of the methysis is strictly prohibited, and in the inevitably there is inertia during the operation of the engine. As a result, while the engine after the Stop command still makes a couple of revolutions of the tool, the self.tapping screw manages to delve into a couple of millimeters.

In addition to ensuring the safety of surfaces, this function is useful when withstanding the tightening force. The risk of overeating falls significantly, the combined materials do not crack due to the excess deepening.

The difference from the work of a conventional mechanism is an instant engine stop after releasing the start button.

The differences between the drill and the electric screwdriver

The conclusion is obvious. Professionals need to buy different tools. At the household level, for periodic use, you can do the same or, which is more advisable to purchase a drill-electrical screwdriver.

Which is better: drill electric screwdriver or drill, and what are their differences

The question of a drill or drill-electrical screwdriver is more complicated, but not critical. The usual drill (OD) as a place of installation of a working tool includes a universal cartridge. Drill-electrical screwdriver (DS) can have both a replaced cartridge and universal cartridge, for drills and bats.

What’s the difference between a drill, impact driver, and a power screwdriver

Household and professional drills

Like many other power tools, drills are divided into two fundamental types:

Sometimes a transitional type is distinguished. semi.professional drills. The principle of operation for household, professional and semi.professional devices is the same. the difference is in power, weight, price, set of functions and some other features.

Household drill to perform the vast majority of simple home repair work will be preferred. Its advantages, except for a lower price compared to professional tools, include:

  • a lightweight design, so working with a tool is easier;
  • Universality. Household drills are often supplied with additional functions, such as an electric screwdriver and a mixer, and in the case with them there are a lot of components with them. Professional drills are focused on the fulfillment of a particular task, therefore, in terms of universality are inferior;
  • Good protection and thoughtful design makes work with a household drill more convenient and safe, which is very important for an inexperienced user;
  • Warranty for household drills, as a rule, is higher than for a professional tool.

On the other hand, it is impossible to use a household tool for more than 4 hours a day, otherwise the drill will quickly break. The optimal time of continuous work is 15-20 minutes, after which the tool is allowed to relax and cool about the same amount of time, then you can return to work again. The thing is that less powerful engines and not so strong materials use less powerful engines to assemble domestic models. This does not mean that the drill will break quickly. this means that it is intended for small or irregular loads

If you have to regularly operate with a drill for 5 hours or more, then it is better to take a professional tool. It differs in the presence of a powerful engine that easily withstands solid loads without overheating and without failing. A professional drill can work continuously for more than an hour and about 7-8 hours a day, breaks can be made small. Such a tool is more expensive than domestic, less universal, more heavy, but it is better protected by dust and moisture, and a professional can not do without it.

Semi.professional drills. a fairly limited class of devices. Transition models can be represented by household drifts with some properties from professional, or professional, but without any elements.

Which drill to choose depends on what work and how often you are going to carry out. If it is needed to hang a shelf or picture if necessary, then you can safely dwell on the household version of the execution. If repairs are your main or additional earnings, then it makes sense to consider professional drills.

Unstressed drills: top 3 best

Not everyone needs to use a shock drill. Someone, for example, does not need to flash the same concrete, well, or brick. But the accuracy of the work is still important. In this case, it is worth paying attention to unstressed options. The absence of the shock mechanism greatly reduces their weight, which means that they can be kept even longer and longer.

OBZOR-Expert experts.COM has allocated three models that will be considered below.

AEG BE 750 R

AEG BE 750 R Basic information:

  • Type of drill: unstressed;
  • cartridge: fast.sounding (from 1.5 mm up to 13 mm);
  • number of speeds: 1;
  • Features: Electronic type rotation regulator, reverse.

Third place. in the German company AEG, which can offer a drill with a long cord, which is quite convenient if you do not want to take various extension cords with you.

Four.meter power cable will definitely allow this to do this. So you can relatively freely move around the room.

This model is quite light and this is due to the lack of an impact mechanism.

difference, shock, drill, electric, screwdriver, they

Her power is quite standard for this type of drill. 750 W. It is also worth noting that the cartridge is clamped quite quickly, which is convenient when you need to start work as soon as possible.

The kit is quite simple. a drill, an additional handle, a drilling depth limiter, as well as a bag convenient for storing the device and accessories bag.

Metabo BE 650 (BZP)

Metabo BE 650 (BZP) Main information:

  • Type of drill: unstressed;
  • cartridge: fast.sounding (from 1.5 mm up to 13 mm);
  • number of speeds: 1;
  • Features: Electronic type rotation regulator, reverse.

The second place is Metabo with its BE 650 model, which looks very elegant, and thanks to the design it is quite convenient. With such a device, any repair will be easy. Due to the small weight, the device is easy to hold in the hand, and it does not get tired of it.

With a power of 650 W, this model will easily manage with the drilling of wood and metal, leaving holes with a diameter of 30 mm and 13 mm, respectively.

With a long power cable and a fast.packed cartridge, this drill can be quickly prepared for work, which is valued during urgent repair tasks.

  • small weight;
  • High productivity
  • long work without heating;
  • The build quality is beyond praise;
  • comfortable handle;
  • Long power cable.

Diold MAS-5-03

Diold MAS-5-03 Main information:

  • Type of drill: unstressed;
  • cartridge: fast.sounding (from 1.5 mm up to 13 mm);
  • number of speeds: 1;
  • Features: Electronic type rotation regulator, reverse.

The first place is in a domestic model, combining a relatively high power of 800 watts and lightness due to the lack of a shock mechanism. The model is quite convenient, because there is no discomfort during its operation.

The cartridge is good, holds the drill tightly, and therefore there is no reason to worry that it will fly out during the drilling process. With a reverse, this model can be used as an electric screwdriver.

The set of the drill is quite pleasant. in addition to the drill, the limiter (it is easier to identify the desired depth of drilling), as well as an additional handle, the manufacturer left the brush to clean the tool. With them to increase the reliability and durability of the device is easier.

Comparison

We have already found out that these power tools perform completely different tasks. But the main differences do not end there:

  • The speed of rotation of the cartridge at the scorchor is significantly lower, plus there is no inertial moment. In other words, as soon as you turn off the screwdriver (lowering the finger from the button), the cartridge immediately stops, while the drill is spinning for some time by inertia.
  • Safety precautions. To work with the drill, experts recommend putting on protective glasses so that small particles formed during the drilling process do not get into the eyes. The scorchin does not need to be observed with special safety precautions, you just need to be careful and neat when working with a nozzle.
  • Various operating modes. It has already been noted above that the drill can include both ordinary and shock mode. The scorchor is regulated only by speed of rotation, no more.

What is a shock drill?

So, by the drill we all absolutely correctly understand the tool designed to drill. Most of modern devices of this type have a “pistol” component that has become a classic with a “trigger” key located under the index finger, pressing the device electric drive starts.

The closest “relatives” of drifts are screwdrivers and peorators. over, this kinship applies to external similarities, and, in many ways, the fundamental coincidence of the tasks performed. In other words, any of these tools can be involved in drilling.

“Close relatives” from one family “Makita”: at one pole a compact electric screwdriver, on the opposite. a powerful peorator. The average position and, perhaps, the greatest versatility. at the shock drill.

So what is the difference? Maybe it will be reasonable to have one of these tools at home. and thereby close the problem completely? It is possible that it is so. But in order not to encounter an unpleasant surprise, when a certain task suddenly becomes impossible to fulfill, one should still understand the difference.

By the way, it is completely incorrect to raise the question. which of these tools is better. This will probably be similar to clarifying what is better. a passenger car or truck? Agree, each vehicle has its own main function, in accordance with which the choice is made. In one case, the emphasis is on the transportation of people, in the second. cargo. And it is very successful if it is possible to find some kind of acceptable intermediate solution, for example, to purchase a pickup.

But back to our tools. With all similarities, their functionality also laid down significant differences, reflected on the features of the design.

Features of electric screwdriver

Electric screwdriver is the smallest of the presented “Trinity”. He greatly facilitated work with fasteners, especially if you have to deal with dozens, and sometimes with hundreds of fasteners. But it should not be massive so that the hand does not get tired of frequent operations, that is, lightness is priority to it. In addition, it is almost always a fast.fast cartridge that allows you to quickly change the equipment.

Of course, a good electric screwdriver should fully cope with the function of drilling wooden, plastic or metal blanks (parts). Many models have the possibility of switching speeds. maximum torque at low speeds. for fasteners, and, conversely, the maximum speed of rotation. for drilling. Often you can find such a combined name as a drill-electrical screwdriver, which, in principle, very eloquently speaks of the breadth of the possibilities of the tool.

The main “trump cards” of the drill-electrical screwdriver-lightness, maneuverability, autonomy. All this allows you to perform drilling and fasteners in the most uncomfortable positions.

But then drill holes in a brick or concrete wall. it is better not to trust a screwdriver. His drive and gearbox are still not designed for such a specific load. Perhaps a certain number of holes will be displayed, but this will inevitably bring the “death” of the tool.

The shock function (more precisely, the shock-standing vector of the working spindle) on the electric screwdriver is not as such.

The specificity of the penetrator

The pediatricrator is located on the opposite “pole”. The specifics of this tool is precisely the presence of a mechanism that can create and transmit a pronounced progressive stress to the working spindle. At the same time, it can be accompanied by a rotational movement of the spindle. when drilling holes in solid materials, and used without it. the peorator turns into a semblance of a jaw.

The peorator allows you to drill holes even in high.strength reinforced concrete details of the building of the building.

It is precisely when drilling holes that the dynamic shock impact is prevailing-with good pressing, the carbular tip of the drill-bore can crush the stones of gravel or gravelly filling of concrete. Therefore, the entire design of the penetrator is “sharpened” mainly to create this effort. Rotation is to some extent even secondary-the drill helps to evacuate the chosen breed and forms a neat hole. In any case, large angular velocities are not required for this.

The massiveness of the tool is here in price, since without it a significant part of the created impulse will simply extinguish the return.

The equipment fixation system in the cartridge at the penetrator is specific, unlike drills, and even more so. screwdrivers.

difference, shock, drill, electric, screwdriver, they

The specifics of the loads tested by the drill over the print on their shape and fixation system in the cartridge. All of them have a long shank with grooves, capable of transmitting great efforts both in the progressive and rotational direction. over, in the progressive direction, the drill inserted into the cartridge has a certain degree of freedom of movement. precisely for the transfer of shock impulse.

How the peorator works, and how to choose the optimal model?

If construction or even large.scale repair is approaching, it’s time to think about buying this tool. believe me, it will be difficult to do without it. Which pedorator to choose for home. What are the evaluation criteria to make to the fore. read in the special publication of our portal.

And what is the shock drill?

It is drilling that is the main function of any drill. Yes, other possibilities are added to it, especially using various attaching equipment. Nevertheless, even the name “drill” itself, without a doubt, comes from the English “drill”, which just means “drill”, “make a hole”.

The design, and the layout of the vast majority of drills are designed according to similar principles:

This is how most of the electric drills are arranged.

The case of modern models is usually made of shockproof plastic (pos. one). It contains a power drive. electric motor. In the body in the area of ​​bearing groups and gearbox, gap.shaped holes for air cooling are provided. For the same purpose, the impeller is usually placed on the engine shaft of the engine, which provides a forced air.

In the rear, the case passes into the pistol handle (pos. 2), for which the tool is kept in the process. On this handle there are most controls (about them a little later).

A power cable comes out from the underside of the handle (pos. 3) with a fork. There may also be an elastic clamp (pos. 4) to place the key in it from the gear cartridge of the drill (let’s say, a short.lived “storage”, it is quickly torn, and you have to come up with your own, more perfect).

Another option, which becomes increasingly popular. the back of the pistol handle becomes a nest for inserting the battery. for tools with autonomous power supply.

By the way, the presence of a battery is not at all a criterion for attributing the tool to screwdrivers, as some think. Proof: there are screwdrivers working from the network 220 in. And you can find powerful peorators with autonomous power from the battery!

There are a compact electric screwdriver connecting to the outlet, and a powerful peorator, which is enough for the full operation of the built.in battery.

In the front of the case, very often. in a separate metal block (pos. 5), the gearbox is located. A working spindle comes out of it in front, on which a zangi cartridge is wound (pos. 6) of one type or another, but unambiguously. has nothing to do with the cartridge of the penetrator.

In very many drift models, the front of the gearbox body, before the spindle exit, has a slightly elongated cylindrical shape. This is done for a reason. it is convenient to fix, for example, an additional stubborn handle (pos. 7). Its fixation with a protracted clamp allows you to set the position of the handle as convenient as possible for the master. In addition, a lot of devices are available that turn the drill into another tool. scissors for metal, jigsaw, miniature drilling or current machine. Many of them are also attached using the mentioned cylindrical part of the gearbox body. So when choosing a tool, you should pay attention to this.

An example of “reprofiling” nozzles for a drill. it turns into a grinding machine (on the left) or into a device for sharpening drills.

To complete with the overall design. another nuance.

The scheme is given approximate, and, of course, in many models it can undergo changes in one degree of complexity. So, you can find a drill with an additional stubborn handle and a somewhat altered in general shape of the case, making them more similar to the peorator. However, according to all other criteria. they remain drones. That is, “brutal” handles. also not the reason to translate the tool in another category.

This arrangement of the handles allows you to make maximum effort when drilling. But the Drill did not from this.

The instrument is launched by pressing the “trigger”. a key located under the index finger on the pistol handle (pos. a.). Almost all modern drones implemented the principle of choosing a speed of rotation by changing the key effort to the key. And the maximum number of revolutions is set by a special regulator (pos. b.), also usually placed directly on the key.

If there is a need to keep the tool on for a long time, then you can fix the start key in the pressed position with a special button-stopor (pos. in.)

As a rule, in the same area there is also a spindle rotation switch, the so.called reverse (pos. G.) Its classic place. above the inclusion key, with the transfer of the “flag” to the left or right side of the drill.

Finally, if the drill is shock (and in our article. we are talking about such), then in the gearbox is located a conventional or shock drilling switch (pos. D.)

There are models that still have a function of switching “speeds”: low, but with maximum torque, and increased, with the maximum number of revolutions per minute.

We complete the review of the structure of the drill precisely with the knot that makes it a shock. And by the way, he is ridiculously simple. There are no complex kinematic or pneumatic schemes here. Just a pair of rates with gear surfaces turned to each other.

Comparing electric screwdriver and drill

In electrical screwdriver, one of the most important parameters is the maximum torque.

Under ordinary conditions, two to three hundred revolutions per minute are enough.

Sometimes a gearbox is placed, which allows you to reduce speed and increase the torque.

This is done using a special regulator.

They are given the force necessary for wrapping a particular type of screw or screw, to avoid their deformation.

Electric screwdriver usually has a reverse to twist the screws or get rid of jamming.

He may have several speeds, anti.ship protection. On sale there are screwdrivers supplemented by the drilling function. The main thing is that the electric screwdriver differs from the drill-electrical screwdriver-the presence of a split coupling, which is regulated by the tightness of the twist, it does not allow deeper than you need to tighten the self-tapping screw.

The difference is also in the holder. If an electric screwdriver involves the use of a bit of the desired size with a hexagonal shank, then a rapidly substantial cartridge under a round in diameter drill is used in a drill.

The drill, regardless of the availability of adjustment, cannot ensure the accuracy of twisting, as a result, the fastener head or the twisting nozzle may be damaged.

The most common electrical screwdrivers and drills can eat from the mains and battery. powerful drills use a network electric width. Especially when it comes to a tool with a function of a blow, where rotational and reciprocating movements are combined.

When using batteries, the advantage of screwdrivers is obvious. With the same charge and voltage, they show the advantage over the drill. This is determined by their technical parameters, primarily the maximum torque.

The duration of each tool depends on the type, voltage and battery capacity.

Most often, household products have nickel-cadmium batteries. Their peculiarity is that they need to be discharged “to zero”, and charge until complete charging.

What is the difference

Both types of tools are necessary in professional activities and everyday life.

Answering the question of how the electric screwdriver differs from the battery drill, it should be noted that the electrical screwdriver has a specific purpose. to tighten and twist screws, screws and screws.

It is convenient when assembling and dismantling various designs, furniture, wooden products, drywall, etc.

Its design allows you to do this quickly and accurately.

The battery drill also allows you to quickly and accurately perform the drilling function.

Both of these tools are good for performing the tasks for which they created.

However, with the advent of effective drills on the batteries with the functions of an electric screwdriver and electric screwdriver with the possibility of drilling, the difference between them is reduced.

The main thing is that usually for twisting it is enough so that the torque is about 9-10 Newtonometers at a speed of 500 rpm.

The battery drill requires the moment up to 20 nm and at least 1,500 rpm.

When choosing the desired tool, you should take into account:

  • type of battery and the presence of a spare
  • the possibility of smoothly adjusting the speed for drilling and twisting
  • Information about the torque that determines the purpose of the tool
  • Ease of regulation of optimal torque.

If we are talking about a professional tool, then screwdrivers can work more time continuously. They wear less.

Hammer drill. This is a special type of tool. It is designed to drill holes in metal, wood and plastic. Outwardly, it looks like an ordinary drill, but it includes a special mechanism that makes a drill (clamped in the cartridge) during operation, which are pushing, like a hammer, movement. Such actions are necessary to perform work with concrete, brick and other stone materials. It is used mainly to punch holes with a diameter of up to 15 mm.

Using a drill

Electric tools are used to work. The capacity for a shock drill is suitable from 400 to 700 watts, but more. There is a switch on its case with which they make a choice between two operating modes. ordinary and shock drilling.While working with a concrete wall, it is necessary to check the processed surface for the absence of electric wires and cables, hidden pipes and other items, only then proceed to drill. It should be borne in mind that the size of the hole made in the wall will be larger than the diameter of the drill used for several millimeters. When preparing the holes for the dowel, its depth must be done up to 0.5 cm larger than the length of the product. Concrete is processed at high speeds, and dust from the hole is removed using a rubber pear. It is difficult to work with a strike drill with concrete, the brand of which is above 300.Make a hole in the brick wall with a winning drill, periodically letting it cool, immersing it in water. Before drilling holes in the metal, this place should be taped (make a small recess). Work on a tree must be carried out at high speed, and with execution or faor. using a bed drill, at small speeds.

Drilling with a blow is not carried out in cases where it is possible to crack material (for example, tiles or ceramic tiles), with proximity to the edges of the walls.

When performing holes in the ceiling, you can put a half of a plastic tennis ball on the drill, which will be a container for collecting falling dust. The drill shock mode is not recommended to be used often, because it leads to a quick failure of it.

Working rules

While working with a shock drill, it is necessary:- Keep it so that the hand is on the axis of the drilling and perpendicular to the handle;- set the speed of rotation in accordance with the diameter of the drill, the greater this diameter, the less its speed should not change;- not change the direction;- not change the direction; rotation of the tool and the mode of its operation, if the engine is turned on;- drill metals, ceramic tiles, wood at low speeds (this is important if you make through holes, t.to. It is necessary to obtain neat edges);- do not apply the reverse rotation of the cartridge to extract the drill from the material- this can lead to its breakdown (reverse rotation is allowed when extracting screws and screws);

The mechanism of the shock drill is short.lived. Its details wear out over time, and it turns from a shock into a regular.

Shock drill, which is better.

When drilling bricks, concrete, the shock mechanism is simply necessary. without a preliminary blow, the cutting edge of the drill simply cannot capture the material. Meanwhile, to have a full.fledged peorator at home is hardly justified. this heavy tool is too highly specialized, so it is not surprising widespread widespread drifts with a shock mechanism. The best shock drills (according to the reviews of masters and experts) are presented in our ranking.

What is the fundamental difference between a shock drill and a penetrator?

If the pedorator’s mechanism is primarily hollowed (a crank mechanism based on a poetic “drunk” bearing with a high frequency accelerates a massive fight with a large frequency), then in shock drills the mechanism uses a simple end ratchet that pushes the cartridge spindle forward with a small amplitude. Hence the difference in handling the instrument (the peorator hits inertia, you need to lean on the shock drill), and in the resource. the rattles of the ratchet under load are licking, the amplitude of the oscillations decreases, and as a result, the shock drill turns into ordinary. Plus, in full accordance with Newton’s law, vibration from the rattle is transmitted in the same way as on the drill.

So do not seriously treat such an instrument. the shock drill is primarily a drill. She will sometimes be able to help the concrete sometimes, but she will constantly work as an order of a peorater in shock mode, and in terms of productivity it can not be compared (the energy of the strike of a professional peorator is comparable to the shot from the IZH-79-9t traumatic pistol, withstand such a shock load from the high frequency of the drill operator would not be physically unable to).
