What you need for a screwdriver. Proper use of the screwdriver

This article is intended for those people who possess extremely small knowledge in the use of construction tools.
We think quite a large number of people begin to get acquainted with the construction tools exactly by buying, and then they begin to deal with how to work with this tool. In addition, probably among readers of this article will be adolescents or women who do not have any idea what is a screwdriver and that with it can be done. For them, we decided to write this article.

So continue ...

To begin with, we will tell you about what is a screwdriver. First of all, they can be divided into two large classes: rechargeable and network operating. The effectiveness of these tools depends directly from the brand of the instrument, but the battery does not have a dependence on the presence of a socket and the length of the wire.

For a home master, it is best to choose a battery tool - it is more convenient and practical. From him and let's start.

Usually, rechargeable screwdrivers are sold in cases, in which, in addition to the tool itself, a pair of batteries and a charger are included. When buying is best right in the store to check the completeness of the instrument and its performance. It is necessary to understand that the screwdriver is supplied from the factory uncharged, so bringing it home it is necessary to charge the batteries with the help of a charger first.

After that, insert one of the batteries into the instrument and it is almost ready for work. To work, we still need to insert another element into the cartridge - the required bit or drill. You can buy a set of bits and drills in the store, and you can purchase them separately, similarly for both drills.

Modern screwdrivers, besides maybe, low-power models have a drilling function and drilling function, so with their help you can also drill holes in both metal and wood and concrete and brick.

Before using the screwdriver, check the integrity of the tool. On the housing and batteries there should be no mechanical damage to the type of dents and cracks. With such damage to operate the tool is impossible.

Drilling metal and wood with a screwdriver

In order to make a hole in a metal or a tree, you must put the corresponding drill in the cartridge. For wood, if necessary, the metal drill is suitable. After that, you need to set the desired mode - drilling. This is done with the help of the rotary part of the instrument immediately behind the chipper's cartridge. On the symbols located on the screwdriver housing, find the image of the drill and align the rotary part (arrow) with its image. At the same time, the screwdriver will switch to the electric train mode. This mode must be used with caution. The fact is that the tool turns off the so-called ratchet (engine protection from excessive force on the shaft). If the drill is broken, the engine can burn.

Next, attach the drill to the drilling point and click on the Start button. In the course of drilling it is important to keep the screwdriver perpendicular to the axis of drilling. Because of the drill skew, especially in solid material, the drill can be broken down. The drilling of solid materials produces on small revolutions, and soft, such as wood on large. By the way, if on the screwdriver there is a speed switch button (usually two speeds), then drill the best in the second speed. In the process of drilling, the force of pressure is controlled independently. Unfortunately, it is difficult to explain it in words, so this parameter can be determined during the practice.

Drilling concrete and stone with a screwdriver

For drilling holes in concrete and stone, we will need a special drill with a winning tip. Usually, everyone uses a drill with a diameter of 6 mm, which is suitable for most plastic dowels under the self-tapping screw. The thicker drill is not worth it - just the power of the screwdriver is not intended for this - the perforator is necessary here.

Before drilling, we translate the screwdriver to the drilling mode with the battle, similar to the above. To do this, compatible the guide arrow with the image of the drill from segments or drill and hammer (depending on the tool brand). As in the previous case, the tool is kept perpendicular to the axis of drilling. It is not necessary to push the tool very much in the process of drilling, although it should be sufficient to gradually blow the drill. Periodically weakening the pressure and even take out the drill from the hole to remove drilling products (dust).

Spinning of screws, screws and bolts screwdriver

Well, finally, we reached the main purpose of the screwdrivers - the wrapping of screws (from which his name follows). On each screwdriver (on the swivel), there is a number of numbers in a circle: 1, 2, 4, 6, 8, etc. They denote the tightening moment in Newton. The thicker is screwed or self-tapping and harder in which this figure should be more. For wrapping, for example, roofing self-sufficiency in the metal is usually enough effort to 12 - 14 N.

To wrap up standard self-tapping screws in a tree, 8 N. Again, this effort is selected individually for each type of screws and base material. It is better to start twisting a new type of self-tapping screws to put a smaller force value, then you can add an effort and trust. But if you immediately put a lot of effort, then you can twist the self-tapping screw, which will lead to a decay of the screw of the self-press, or twisting (self-tapping and screwing the fixable material).

Depending on the head of the self-press or screw, you will need a variety of bits. For standard Self-tapping screws, the PZ2 bit, for the small Self-tapping screws of the PZ1 bit, and here for roofing self-tapping screws for 8 mm. Also with the help of a screwdriver very convenient to collect cabinet furniture. If you have a bit for confirmation (Eurovint), then the level of furniture assembly will increase several times. In addition, it will cost without mazoles on the fingers from twisting manually by a large number of confirmates.

The mode of wrapping of self-tapping and screws has one very good property. If the base material turns out to be too solid and the screw is screwed during the twisting, the so-called ratchet will work. The special mechanism will stop the transmission of rotation from the engine on the bit, which will prevent its damage. All this is accompanied by a characteristic crackle. It should not be afraid.

By the way, on twisting mode, you can easily drill the tree without changing the mode, the drill is easy enough. If the tool's efforts are not enough to twist self-pressing into solid material, experienced masters translate the screwdriver into drilling mode and reach the self-tapping screw. But we do not recommend this, since you can simply burn the electric motor without the necessary experience.

During the twisting, it is necessary with a sufficient force to press the bit to the screw of the self-press, so that the bit does not slip. If the edge of the bits are slipped and it fails.

At the end of the article, we note that it is best to store the electrical journery in a dry, heated room. Because of the humidity, the contacts tool will be oxidized and it may fail. Keep the screwdriver batteries are necessary in the charged state. So they will serve much longer. If the batteries stopped holding a charge, then in service centers you can always order new ones.

We hope our instruction helped you in work and benefited.

Screwdriver - a tool with which you can quickly screw fasteners (screws, screws, screws); It is used to collect furniture, hang shelves, drill holes, install suspended ceiling or crate. To understand how to properly use the screwdriver, it is worth learn more about how it works, what work can be performed with it.

Types of screwdriver

Modern devices are divided into subspecies that differ in functionality.

Exist:

screwdrivers with which you can only twist fasteners;
wheelners used to twist the hexagons;
rechargeable screwdrivers - the least powerful simplest tools;
drills-screwdrivers used as well used for drilling holes.

By type of power, devices can be battery or network. The first are considered more convenient because they allow you to carry out the work away from the outlets, including on the street.

The screwdrivers can be with a key cartridge for fastening the drill or quick-release.

Selection of tools

The most important indicators to pay attention to when buying is the speed of rotation and the power of the screwdriver.

The speed of rotation affects the functionality of the device. To twist or unscrewing fasteners, the tools are suitable, whose speed does not exceed 350 revolutions per minute. The drilling will require devices, the speed of rotation of which is higher or equal to 1000 revolutions.

If you plan to purchase a battery screwdriver, you should find out its type. The most common devices with lithium-ion elements that are distinguished by a long service life. They are recommended to choose if the device will use often.

If working with the use of the screwdrity is rare, the nickel-cadmium element is more suitable - they are cheaper, they are not so prone to self-discharge as lithium-ion. For extremely home use, devices operating from the network will also be suitable.

Additional parameters that will make work with a screwdriver easier and more convenient:

illumination of the working area;
pulse increasing torque used for drowning fasteners;
shock mechanism;
increase the speed of rotation.

Design

The tool consists of a housing in which the engine and gear mechanism is located; cartridge (clamp for replaceable drills); Battery or cord to connect the device to the network.

Preparation for work

Before using the screwdriver, you need to pick up a nozzle that is suitable in size to the cap of the fastener. To install into a tool with a quick-inspection cartridge, the nozzle is pushed between the cams, turn the sleeve clockwise. To fix the nozzle in the device with a key cartridge, the key is inserted into the socket, turn clockwise until it enaches.

A device equipped with a battery should be charged, and the device running from the network is included in the outlet.

To make sure that the screwdriver is working, at first it is turned on in good. Watch whether the direction of rotation of the nozzle is fastened.

Screwing and twisting fasteners

The instruction on the use of the device is simple:

The tip of the nozzle is inserted into the slot of the self-press or screw, turn on the device.
To increase or decrease the spinning speed, you should strengthen or reflect the pressure on the start button.
When the self-tapping will be twisted, the mechanism will automatically work the mechanism of limiting effort, after which the work will stop.
To unscrew the screw, the nozzle is placed in the slot, after setting the lever direction of rotation of the nozzle in the opposite direction.

Features of operation

Incorrect work and breakdowns may occur after switching to the instrument operation modes during the rotation of the cartridge. That this does not happen, it is recommended to perform all operations only after turning off the screwdriver and stop the engine stop.

It is also necessary to properly select the torque of the device, given the hardness of the material with which:

DVP and plasterboard. To spin self-tapping screws into these materials, 1-4 modes are used.
Wood solid rocks. The regulator ring is moved to the maximum value.

Important! It is better to set a smaller torque value than required. When choosing an overpriced value after twisting the screw, the cartridge of the screwdriver will continue to rotate, and will not stop, as it should be. Slot will be damaged.

Use the screwdriver as a drill can only be briefly. With a long-term load of a tool that is not intended for drilling, the electric motor can overheat, which will damage the device.

Safety regulations

It is impossible to make moisture, sand and construction dust inside the tool.
The room in which the work passes must have high-quality lighting. In the event that an electricity operating screwdriver is used, you should make sure that the network is stable, there are no voltage drops.
Switching operation modes are carried out only when the tool engine is completely stopped, in the off state.
If the tool begins to work with an effort, the speed of revolutions reduce or turn off it for a while.
It is impossible to touch the instrument of grounded items: the worker can strike the current.
So that the screwdriver regularly worked, the cartridge is regularly lubricated and cleaned from dirt.

Knowing how to use the screwdriver correctly, you can not make common mistakes of beginners, which significantly reduce the service life of the device and sometimes lead to the complete output of the instrument.

How to use a screwdriver?

It often happens that without a screwdriver can not do. The screwdrity is an indispensable assistant in the manufacture of the suspended ceiling, the mounting of the drywall. Repair works are complicated, if there is no screwdriver at hand, which can easily spin the screws and fasteners. In the household sphere, it is in demand no less than in professional activities.

However, how to use the screwdriver, not all the tool owners know about it. There is no hard thing about it, the main thing to adhere to some rules and recommendations for beginners.

Tool varieties: characteristic signs

Screwdriver can be classified for the following varieties:

Drill-screwdelt
Gaikovert.
Rechargeable screwdriver
Standard screwdriver

The principle of work in the tools is similar to each other, but still there are differences in functionality.

Drill-screwdriver is able not only to spin the screw, but also to drill a hole. The wrench specializes in bolts and nuts. The third representative is a battery screwdriver, designed exclusively for twisting / unscrewing the fastening elements with a cross-shaped hat. The latter species is characterized by low power, unlike the above.

What is the screwdriver? Device setup.

In the plastic case there is a motor and a gear mechanism that actuates the bit that is installed at the end of the screwdriver. The device is provided for the presence of a start-up toggle, direction switch and speed, diode highlighting and tightening time regulator.

The principle of the instrument is very simple. The nozzle, pre-fixed in the cartridge, moves with a shaft, which proceeds to move from the motor operation through a gearbox. Before using the screwdriver, it is necessary to find out whether the battery is charged, and the right nozzle is installed.

Immediately before performing the work, you need to look after such a nozzle so that it corresponds to a self-supersay hat or screw.

To install the desired nozzle, it is necessary to pick it up with the magnitude of the cap of the fastener element and fasten in a magnetic cartridge holder. First, the cartridge with the coupling must be removed from the device, and after fixing the bits, the cartridge must be fixed to the casing of the screwdriver.

Then you need to assign a suitable frequency of bits. Setting is performed by means of a special regulator. The required mode is set in the tool disconnected state.

Before using the power tool, you must adjust the depth of screwing the fastening element. After some time, the need to replace the magnetic holder may occur. To change it to be removed, the cartridge, magnetic fastening and coupling. Next, the cartridge with the coupling is fixed back to the screwdriver block.

After the desired nozzle (bit) is selected for the drill, given the magnitude of the screw screw and the configuration of the recesses (straight, cross), it must be installed in the heart of the open cams, and fasten in the cartridge by turnover the sleeve at the time direction. If a key type is selected, then the key is set to the deepening on the cartridge, and then turns on the hourly until the nozzle is secured. The end of the nozzle is placed in a scarpet groove. Before the device is running, check the accuracy of the direction of rotation direction, the direction must match the screw of the screw.

Increased pressure on the start button adjusts the optimal rotation speed. With full immersion, the screw is activated by the mechanic limiting effort, and then the drill stops.

After the end of all settings, you can take the use of power tools. After examining the instruction manual of the screwdriver, you can prevent possible malfunctions in the process of handling the device, thereby increasing the service life of the tool.

It is not allowed to configure the frequency and direction of nozzle revolutions in the included state of the device. You can not touch the power tools to grounded objects, otherwise a person can strike the current. Do not use the device for a long time because it can burn.

The room in which the screwdriver is best to be well lit, and the power supply is constant, without jumps, it will avoid equipment malfunctions. Work should be held in specialized clothes and only with a good tool.

Is it possible to use drill as screwdriver

The screwdriver can be used as a drill. The cartridge mechanism makes it possible to firmly fix the drill with a cylindrical tail. To get started, you will need to install the drill on the clamping cartridge.

Be careful, as the design is not provided to do the holes, especially the solid wood, metal or concrete, because there is a high probability of breakage of the planetary gearbox.

Maintenance screwdriver + (video)

There is nothing remarkable in service, since today modern models have increased strength and withstand even falling from a small height. The cartridge should be regularly lubricated and cleaned. Avoid moisture ingress, sand dirt in the middle of the instrument. Follow the overload of the screwdriver if you feel that the screwdriver begins to work with effort, lower the speed of revolutions.

Device and appointment of power tools

Screwdriver applies to twist and unscrewing various fasteners. The tool can be cutting the thread and drill. It makes it much easier and speeds up work. Sculptors are used in everyday life, construction, assembly of furniture, in the car service, wherever need to work with a lot of fasteners.

Screwdriver can be rechargeable and network

The main elements of the screwdriver:

Cartridge.
Torque adjustment coupling.
Speed \u200b\u200bshifter.
Engine in the screw is screwed.
The reducer is enclosed in the tool housing.
Reverse switch.
Power button.

Types of bits for screwdriver: how to choose

To select the nozzles correctly, you need to study their varieties. First, determine the type of shape of the shank and diameter. It happens from 1/4 to 1 inches.

Classification of shanks:

main;
special;
combined.

Types of major bits:

Types of special bits:

Combined bits have two types of shape of the shank or one, but of different sizes. For example, a slotted shank and the stars.

Example of a combined nozzle

Slot Shank and Star

Determine the bit length that you need to work. It ranges from 10 to 200 mm.

Depending on the shape of the shank, the nozzles have a definite labeling:

SL (SLOT) - Slotsey;
PH (Philips) - Cross-shaped universal;
PZ (Pozidrive) - Cross-shaped with additional subtle ribs;
T (Torx Hole) - Stars;
H (Hex) - hexagon.

An important characteristic is the steel brand from which the bit is made. The nozzle may have a torn coating. The durability of the equipment depends on it. The main types of steel and covers that should be preferred:

Nozzles differ depending on the purpose:

twisting and unscrewing;
drilling;
skill;
polishing;
milling.

Considering all the considered parameters, you can easily choose the necessary bits.

How to work with nozzles

Different cartridges are installed in screw leads. Consider how to change the nozzle in all types.

Magnetization and hardening of the nozzles

A large number of nozzles produce in China from a soft material. Therefore, they quickly lose their shape. The new bits grabs quite a while. To extend the service life, the nozzle must be hardening. You will need: Machine oil, gas burner or gas stove, small oil capacity from any tin can, piece of steel wire.

The hardened bit will serve longer than the usual.

Video: Overlaying Bit Oil

For the convenience of work, especially in hard-to-reach places, the nozzles are magnetized. This can be done in several ways.

Method 1.

You will need to purchase special screwdrivers. Insert the bit there. The square window magnetizes, and the stepped - on the contrary.

Device for magnetization and demagnetization

Method 2

Method 3.

Method 4.

As a result, the nozzle will magnify the fastener better than the new one.

Video: Magnetization of bits with neodymium magnets

After purchasing a screwdriver, observe simple recommendations for use. And then the tool will work for a long time and qualitatively:

before connecting and removing the battery, turn off the screwdriver;
do not bring the tool until overheating, take breaks;
correct torque adjustment clutch;
after applying high revs, install the minimum and lead the engine in a fast-minute engine so that it is cooled;
check the power screw cable, and at the battery-network cord of the charger. If the tool or charger periodically loses the network, the wire must be replaced;
do not use screwdriver in the rain and snow. In a wet environment, you can only work under the canopy.

How to regulate turns and effort

The rotational speed varies with the switch, which is located on the screwdriver housing. High speed is used for large bolts and screws, as well as for drilling, if such a function is present.

Speed \u200b\u200bshifter

Many models have an effort limit coupling. Its presence in the power tool can be determined by a rotating ring with numbers. Some users do not understand the values \u200b\u200bof the coupling and do not touch it. Using the ratchet, you can adjust the depth of screwing the screw. In the too soft material, the fastener hat is easily comfortable and can pass through. When using fine fasteners, a very high torque can destroy it. The ratchet prevents the cutting of the slot from the screws and wear the bits of the screwdriver. To determine the desired value on the adjusting ring, make several goals starting with the minimum. For drilling mode, the maximum torque is used. But only with such a function.

Coupling Limitations Efforts

The start button also adjusts the speed of rotation, but not more than that is installed by the switch. Suppose you put the switch to the first speed, which is declared to 800 rpm. With a maximum press on the trigger, the speed above will not rise. And torque in the maximum mode will be low, that is, you will not be able to twist the large screws and drill. And if you set the switch to the maximum speed, you can drill and turns will be much higher.

Adjust the speed, torque and reverse in the disconnected state of the tool.

Tool use options

The screwdriver can not only twist and unscrew the fastener. To make the tool, it can be found, it can be found a lot of applications.

Is it possible to use screwdriver as a drill

You can only drill a screwdriver if this mode is provided by the manufacturer. Then the drilling will be safe. Carefully read the instructions. On the coupling, this is the last position or pictogram with the image of the drill.

Designation of drilling mode

In screw leads with a drilling function, a quick-release or key cartridge is installed. A magnetic or snatching cartridge will not be able to keep the drill and ensure the safety of work. To replace the equipment, do the following:

Another application

Using various nozzles, the tool can be performed by the following works:

You can still find a lot of applications for this tool. But remember that you need to work in protective glasses and gloves.

Care and storage

disarmatically disassemble and clean the internal elements of the screwdriver from Nagara, dust and dirt;
in case of unstable work, conduct diagnostics. Check the brushes wear so that the engine anchor should not be changed;
do not leave the instrument in rooms with high humidity and under the sun. The same applies to the battery;
do not keep the battery next to keys, coins and other short metal objects. With random contact with poles, a short circuit of the battery will occur. As a result, a fire may occur;
at the end of the working day, take clean rags and wipe the tool. Rag can be slightly moistened with water without using detergents;
keep screwdriver needed in a dry medium with a plus temperature. Use a case or other packaging so that the tool is not covered with dust.

Work screwdriver, observing the safety and rules described in the instructions. Pick the right tool. And then the tool will serve you for a long time.

Instruction: how to use a screwdriver

The word "screwdriver" is present even in the lexicon of kindergartens. After trying on the construction helmet and taking toy tools, they begin to get acquainted with their destination. Even children understand that without a screwdriver could not do, if, for example, you will need to hang in the room the picture or replace the spoiled door lock. But how to use a screwdriver, not anyone and adult is known.

The screwdrity is used in wood, metal, and if necessary, the preparation of a small hole in the concrete wall, if more large-scale work is coming, it is better to use a drill or a perforator.

Screwdriver and Drill: Subtleties Differences

The presence of a plug indicates a drill, and the battery is a screwdriver. Typically, such a response is given by the streets when they are asked about the distinguishing criteria for instrument data. He is incomplete and not quite correct, as you can use the screwdriver by connecting it to the power grid.

Those who are more attentive to have seen and enjoyed this tool indicate the rapid termination of its operation - immediately pressing the corresponding button. The reason is the brake of the eleg, which there is no drill. Even when it was turned off, the cartridge is still moving and can damage the screw.

The screwdriver has a quick-release cartridge and a torque regulator. Setting the latter to the maximum position, the screwdriver used becomes a drill.

Being only the buyer, it is necessary to assess the convenience of working with the tool. Not bad if he has a fastener loop. This small device needs to take advantage when the tool is not in operation.

Scheme of the device of the screwdriver.

How to use a screwdriver, you can read in the instructions to it attached. But even more principled will be the solution to diligently explore the device of this device and only then following the recommendations, to accurately collect it. For example, the cartridge of the screwdriver after replacement must be securely secured by a special screw. If there is an error, then during the starting start it can jump from the shaft that performs rotational movements. Then you have to correct this trouble or even refer to the traumatologist.

In addition, by taking the tool assembly, you need to be careful with the electric motor. An incorrectly installed switch and more than necessary, the wriggled wires threaten the screwdriver.

By purchasing a battery device, you need to know: the first time the battery can be charged to twelve hours.

If there is a desire to experience this device, applying it as a drill, then large revs are needed. Because in this case it is necessary to use the screwdriver a short time. As an alternative, a different method is used: reducing the speed of rotation.

Proper nozzle - effective result

Scheme of nozzles for a screwdriver.

What to choose the nozzle to perform the task most effectively, you need to think in advance. It is necessary to work with wooden materials, and took the metal drill - the result can upset the initiator of the repair. It happens that the drill has to be replaced. The screwdriver can be used when it is necessary to prepare a small deepening in the wall made of concrete. But if global work is coming, then you should use a shock drill. It is useful here and the perforator.

If you purchase special nozzles (bits) inexpensive, then bolts, nuts and self-tapping screws can not be spinning quite efficiently. Usually on cheap models do not have a workshop located on the workspace. The material from which bits are made should be durable. Otherwise, such an unpleasant situation will be formed: we use a tool for a long time, and a little incorrectly turned - and discovered wasteless faces. Exit - replacement of the nozzle.

Choosing bits, do not save on additional properties (magnetic), which, when working in hard-to-reach areas, have their advantages.

After selecting the bits, you need to correctly configure the tool. In this regard, it is necessary to realize how the spindle rate changes is occurring: they pay attention to the switch.

What kind of depth is required to complete the screws, adjust, using the cartridge.

Screwdriver breaks needed

For a screwdriver to serve the owner for a long time, it is necessary to use them and remember: loading the mechanical parts of this construction tool at the maximum should not count on prolonged and at the same time efficient operation. If the electric motor works on maximum revolutions, it can overheat and lead to malfunctions in the winding. Special nozzles are also unwritten: contacting with materials intended for processing, they are heated. Therefore, experts recommend periodically to arrange breaks to cool the drill. With the help of water, it is not necessary to solve this problem: sharp differences of temperature indicators are undesirable.

The compilers of the instructions to the tool are warning: to adjust the bits rotation course, the frequency is prohibited if the screwdriver is enabled. Where this apparatus has to be used, sufficient lighting is required and a stable operation of the power grid.

It is necessary to be careful if there are objects with grounding. It is strictly forbidden to touch them a screwdriver, the blow to the current to anyone will not be pleasant. Defending himself, a person must treat the tool carefully. For example, it is necessary to ensure that the housing does not threaten moisture.

Use the screwdriver carefully. Prepare holes in the concrete surface easily, but it should not be harmful to their light and bronchoms. Without special protection (a respirator is carried out here) it is better not to take for this repair operation. The glasses will not interfere, which will not allow the contact of small alien particles into the sensitive area of \u200b\u200bthe eye.

In the modern world, this hand tool is very often used in the economy. But not everyone knows how to use the screwdriver correctly. To the tool worked without failures, it is necessary to adhere to the established rules.

Types of screwdrivers

The screwdriver is network - it works when connecting to the network, and it happens the battery. On the basis of this distinguish several types of tools:

tool of the usual type;
device for unscrewing or for twisting wrench fasteners (wrench);
electrical appliance for unscrewing screws or screws (drill-screwdriver);
rechargeable screwdriver.

All types of screwdrivers are similar among themselves on the principle of work. The difference is in purpose and the functions performed. In addition to the basic functions, each of the listed tools can be used to perform other tasks.

Drill screwdriver applies when it is necessary to make a hole in the surface. Bolts and nuts are easily twisted and twisted with a wrench. If you need to remove the fastener, on the hats of which the cross, use a battery screwdriver. Compared to other, such a screwdriver is low.

The use of them in everyday life simplifies work with fasteners, and time for such actions is being spent much less.

How to configure a screwdriver before operating?

The screwdriver has a simple design. The engine is built in the plastic case. At the end of the device there is a bit. In order for this design element to be started, a gear mechanism is used. In addition to these parts, the mechanism of the screwdriver includes other working details:

inclusion toggle switch;
switch that changes the direction and speed of movement;
highlighting diode;
detail, adjusting tightening moment.

Before running the mechanism, it is necessary to carefully check whether the battery is charged. The perfect option is an extra option. Then it will be possible to continue working, changing one on another. During this time, the sitting battery will have time to charge. After connecting to the supply element, the device is checked at idling.

Then it is specified, whether the nozzle is chosen correctly, which is selected according to the size of the fastener cap. Insert it into a special cartridge holder.

So that the nozzle tightly sat down into the holder, the cartridge and the coupling are removed. After the final installation, the patron must be attached to the case.

The next step is to set the speed of rotation of the bits. For this purpose, the screwdriver is mounted in the screwdriver. To adjust the rotation before the start of operation. The torque value is selected in accordance with the hardness of the material being processed. If it is not known exactly what moment it is better to install, then your choice must be stopped on an understated value. Using the regulator, you can change the direction of the bits. Next, the depth is adjusted to which fasteners will be wrapped.

In case of failure of the magnetic holder, it can be replaced by valid. To do this, remove the cartridge and clutch, remove the holder, set the replacement. As soon as the new item is in place, the cartridge and the coupling are returned to the housing.

Cautions when operating tools

Equipment is ready for use only after all settings are performed. The device connects to the network or the battery is adjusted to it. You can enable the tool and perform actions for which the selected screwdriver is intended.

So that the service life is as long as possible, all previous rules must be accomplished strictly. The quality of the work performed will be much higher when all settings are executed. In addition, the time to work is much less.

In no case cannot be changed settings in the work equipment. A liquid or any other moisture should not fall into the housing. Lighting during the operation of the device should be good. If voltage differences are observed in the network, it is better not to use a screwdriver (this rule concerns only the equipment that is powered by the network).

Ensure that the device does not touch the grounded items. Otherwise, the Master threatens a blow to the current. A working mechanism should not overheat, so it is advisable to make pauses for cooling. Working without stopping, one of the details can burn.

Before use, you must read the attached instructions. If the tool is faulty, it is better not to take it to work. While working itself to secure damage with special clothing.

Thus, the device is quite simple on the principle of operation and in design. But many masters use a tool, allowing a lot of errors, which subsequently reduces the service life, and work is carried out poorly.

In order for no emergency situations during operation, the master did not suffer, it is necessary to comply with all safety rules. Compliance with these rules for each master, even a novice.

You can choose the appropriate version of the equipment without leaving home. Enough to go to the online store Interskol. The company is a leader in the electric tool sales market. Interskol products attract customers with low cost and excellent quality.

What is a screwdriver? In fact, this is the same drill, but the screwdriver differs from it because it has a smaller speed of rotation of the cartridge and, at the same time, greater torque.

Another difference is if the rotational speed can be changed smoothly, then on a screwdriver, as a rule, "fixed" rotation speeds of the cartridge are installed. This is due to the "slipping" function of the screwdriver's cartridge: when the screw is twisted, the cartridge stops rotating, although the engine still works. This function allows not to break the slots and not "drive" screw inward.

Different types of speeds are designed for specific types of work and materials, as well as the "drilling" mode. Just like a drill, a screwdriver has a reverse function. The design features of the screwdriver make it possible to perform a wide range of works: twisting and unscrewing screws and screws, screws and nuts, drilling soft materials.

The use of a screwdriver, for example, in the production of plasterboard partitions or when assembling furniture, increases the speed of work at times. Therefore, the screwdriver is considered to be one of the most common tools in a set of any master.

The designs of all screwdrivers are approximately the same. They are sufficiently light and have a "pistol" handle, designed to work with a tool with one hand.

The start key is arranged in such a way as to adjust the speed of rotation of the press.

An important element of the screwdriver is the source of its power. If the drills are produced in modifications both with power supply and autonomous (battery) variant, then the screwdrivers, due to the features of the application, are almost exclusively accumulative. The battery is the most severe and most expensive part of the screwdriver.

Household models of screwdrivers are usually equipped with nickel-cadmium (they have the designation "Ni-CD"), and more expensive professional - lithium-ion ("Li-Ion") batteries. Their difference is that nickel-cadmium has a smaller service life (about 1000 recharging), and also have one unpleasant feature: if the battery is not completely discharged, during subsequent charging, its capacity decreases.

But whatever the battery, its capacity is limited to the weight of the instrument. Therefore, even the most expensive models of screwdrivers are able to work continuously no more than a few hours. Some manufacturers solve this problem by introducing a second spare battery screwdriver. However, it significantly increases the cost of the tool. The battery is charged from the usual network. Charging speed again depends on the model and can be from 2-3 to 6 hours, although in some models of the screwdrivers provided "fast" charging for 10-15 minutes.

Rules of work

It is easy to operate a screwdriver. In the chips of the cartridge, the necessary nozzle ("bit" or wrench, or drill) is clamped ("bit", or by pressing a screwdriver with some effort, the key pressing the button is rotated. If you need to unscrew the screw or pull the drill, the reverse is turned on. When working should be followed by several rules:

Before working as a screwdriver, fully charge it. At the same time, strictly follow the requirements of the charging time instructions for the battery in the charger shortens its service life.
When working correctly, choose the "screwing" or "drilling" mode correctly - so you protect the engine and the screwdriver gearbox.
Remember that the screwdriver is not intended to drill a stone or concrete.
Try not to quit and not drop the screwdriver is a fairly fragile tool.
Keep a screwdriver clean - remember that small dust and dirt particles act in rubbing parts as abrasive, and the elements of the screwdriver fail faster.
Now you have a general show that is a screwdriver and how to work a screwdriver. It's time to take a tool in hand and create!

Rechargeable Drill Screwdrift

Bosch PSR 18 Li-2 rechargeable screwdriver.

A fairly simple screwdriver for home use, the main advantage of the device is a universal lithium rechargeable battery, suitable for the electric lobby and the delta grinding machine.

The weight of the screwdriver along with the battery is 1,3kg. That is, it is not heavy, but not light. At the same time, the maximum moment - 46n * m, which is not very bad.

The turnover is regulated, as in most other screwdrivers and drills - button. Also standard, the direction of rotation direction of the cartridge is located nearby.

The screwdriver has a standard quick-swampy three-tailed cartridge. The maximum diameter of the drill shank, which can be closed in this cartridge - 10mm.

The manufacturer does not recommend using this screwdriver, for drilling large holes: in steel more than 10mm, in the tree more than 35mm.

To fix the bit or drill in a quick-release cartridge of the screwdriver, it is enough to fix the cartridge with hand and turn on the screwdriver to large speeds.

How to work screwdriver

And the cartridge itself will chamoge the drill.

To remove the drill or bit, you need to switch the screwdriver to the reverse, fix the cartridge and turn on the screwdriver: the cams will be released and release the drill or bit.

Standard in the screwdrivers, the moment of restriction of the moment. At the top of the housing, opposite the cartridge there is a shooter that indicates the number. The greater the number, the greater the moment withstands the coupling without shutting down. In total, the coupling of 10 provisions with different settings of the moment, plus the drill mode. In drill mode? Which is marked with the inscription "Drill", the moment of time limit coupling is turned off. And with the help of a screwdriver can already be drilled.

This screwdriver is two speed range from 0-400 revolutions per minute and from 0 - 1340 rpm. The speed can be switched by a red engine switch at the top of the screwdriver, in the "Back" position, the screwdriver works on the first - low speed. If the engine is moving forward, then the second speed turns on. In addition, speed number can be seen in the window next to the switch.

Convenient newbie option - Rotation direction indicator: Two triangle at the top of the device, help determine in what mode a screwdriver works: the arrow forward means that the cartridge rotates clockwise and, accordingly, wraps a screw, if the arrow of the back, then the cartridge rotates counterclockwise And turns the screw.

On the screwdriver there is an indicator showing the degree of charge of the battery.

And there is a lamp of the "PowerLight" backlight, which will help to work well when working in poorly lit places.

Drills a wooden bar in "Drill" mode, i.e. With a muffled coupling. For a relatively thin drill, you can turn on the second speed.

To screw the screw, you need to choose a bit that will suit this type of screws.
The main types of shlits, in the photo to the left for the right:

1) Philips,
2) Pozidrev,
3) straight,
4) star-shaped (Torx),
5) Hex (Hex).

In addition to the form, the slots are distinguished by sizes and under each slot size of the screw or screw, you need to take the bit of the desired size.

So, the desired bit is selected and clamped in the cartridge, but for screwing the screw, it is necessary to turn on the first speed and set the coupling to the point limit. In our case, for such a diameter of screws, we choose the position "17".

On the photo the result of screwing the screw to different depth. When the screwdriver fully certifies the screw, the overpowering force will increase and then the coupling of the moment restrictions will start. Thanks to this, the screw does not enter deeper than and not a split broom.

Lithium-ion batteries on which the battery is built is very good and you will not need to replace the batteries in the screwdriver for a long time.
