How to remove a bit from a screwdriver. Correct use of a screwdriver Interskol screwdriver how to insert a drill

- an indispensable assistant for both an experienced builder and a home craftsman. The key to trouble-free operation of a tool is its correct operation.

Preparing the screwdriver for work

Start preparing the tool for work by providing power to its power element. If you are using a screwdriver powered by 220 volts, ensure that it is securely connected to a power outlet.

If the tool is powered by a battery, take care in advance to charge the battery from a charger.

Even better, stock up on a backup battery, then one battery will “turn” the screwdriver, and the second will be charged at the same time.

After powering up the tool, be sure to check its operation in idle mode.

The next stage is installation of equipment. Rotating the movable part of the cartridge counterclockwise with your hands, unscrew it and insert the nozzle with a magnetized holder into the cartridge.

To close the jaws of the chuck and secure the attachment, rotate the movable part of the chuck in a clockwise direction.

Experienced builders install or replace equipment using the power of the electric motor of a screwdriver.

The procedure is as follows: firmly grasp the cartridge with one hand (fortunately, it has an anti-slip rubber coating), and with the other hand hold the tool, turning it on in operating mode until it stops.

The final stage of preparatory work is to select a suitable configuration and insert it into the nozzle holder. Due to the fact that the holder is magnetized, this operation is unlikely to cause difficulties for anyone.

Tool operation

Most often, a screwdriver fails due to switching its operating modes on the go, directly while the chuck is rotating.

Perform all manipulations with control elements (changing torque, direction of movement of the chuck, switching speeds) only after the tool engine has completely stopped.

It is very important to select the correct screwdriver torque depending on the hardness of the material being processed.

For tightening self-tapping screws in or fiberboard, modes from 1 to 4 are sufficient. In the case of working with hardwood, set the regulator ring to the position with the maximum torque value.

When choosing torque, it is better to play it safe and set it to a slightly lower value. The only thing that threatens this is that the force limiting mechanism will work.

Simply put, the ratchet will work or the tool’s motor will stop, but the self-tapping screw itself will not be screwed in completely.

By turning the adjuster ring in the direction of increasing torque, increase the force transmitted from the screwdriver to the bit, and tighten the self-tapping screw on the second attempt.

Things are somewhat worse if the torque value is set to be greater than required. After the screw is tightened, the force limiting mechanism will not work and the screwdriver chuck will continue to rotate.

What does this mean? Damage to the screw slots. If the screwdriver is in strong hands, and the contact of the bit with the self-tapping screw is tight and reliable, due to sudden braking of the engine, it may fail.

This operating mode will also have a negative impact on the battery life.

A screwdriver, if inserted into its chuck, can be used as a drill. When drilling holes with it, do not forget that the normal operating mode of a screwdriver is short-term switching on.

Prolonged (without breaks) operation of the tool will lead to overheating and failure of its electric motor.

Good luck to you! May everything work out for you!

A screwdriver has become one of the most popular tools for interior finishing work. This is explained by the widespread use of wall panels, suspended ceilings, and the use of wooden slats as cladding material. These works require the massive use of screws and screwing them into the surface. Therefore, the issue of proper operation of the device so that it works for a long time and reliably is relevant. In this article we will talk about cordless screwdrivers, as the most popular type of this tool.

To put this device into working condition you must:

1. Take it out of the case and inspect it for visible damage - cracks on the case, etc. If they are found, it is prohibited to use the tool.

2. After inspection, attach the battery to it, and then make sure that there is enough charge to start work. If the battery slowly rotates the tool spindle, you need to remove the battery and put it on charge (see how to charge it below), and connect another battery to the tool instead.

3. After making sure that the battery has gained sufficient charge, the required attachment is installed in the screwdriver depending on the nature of the work (tightening screws or drilling) and the size of the screws. We will talk in detail about installing the attachment further, but here we focus on the fact that for the safety of work during installation or replacement of the attachment, the battery must be removed so as not to accidentally turn on the screwdriver.

4. Using the controls on the instrument, select:

• operating mode - drilling, working with screws, some models also have an impact mode, for example, the .
• rotation speed of the nozzle (if the tool model has several stages of rotation, for example); direction of rotation - for drilling and tightening screws clockwise, for unscrewing screws - counterclockwise.

5. If you have to drill to a certain depth, then in screwdriver models that have limiters on the drilling depth, you need to set it.

Remember that proper preparation of the tool is the key to working safely with it.

The most important part of the operation of the tool, on which the operating life of the device largely depends. How to charge a screwdriver battery depends on its type. The most common are lithium-ion batteries. Such a battery, with its compact dimensions, charges quickly and has no memory effect. The main disadvantage is the rapid discharge in the cold and the high price.

Older models use nickel-cadmium batteries. They are cheap, reliable, but have a memory effect. That is, if you do not completely discharge them before charging, the battery capacity will gradually decrease.

How long you need to charge a battery depends on its type and capacity. Li-Ion batteries charge the fastest. The battery of a household screwdriver charges within an hour. The same capacity will charge for 7 hours.

How do you know that the screwdriver is charged? There is an indicator on the charger, for example, for the model, it is on the right. The red light is on - the battery is charging, the green light means it can be used. You can also rely on your own experience. By the charging time and the nature of the screwdriver’s operation, you can judge whether its battery is charging.

If you have a model with a nickel-cadmium battery, then you should know how to pump up the screwdriver battery, which will inevitably reduce its capacity after several years of use. And if you use the tool incorrectly, that is, do not let the battery fully discharge before charging, then it will be faster.

In order to restore capacity, you need to know how to discharge the screwdriver battery correctly. And this means a gradual decrease in charge by connecting a twelve-volt light bulb with a power of 25-40 W to it. After complete discharge, charge the battery to capacity and then discharge it again. Repeat the procedure at least 5 times. This procedure cannot completely restore the capacity, but it will significantly increase the operating time of the screwdriver.

Equipment installation

The screwdriver can be equipped with drills or attachments for tightening and unscrewing screws. When the required attachment is selected, it is necessary to rotate the chuck sleeve counterclockwise until its jaws are separated enough to insert the shank of a drill bit or screw bit between them. Then clamping is done in reverse order. There are two types of cartridges:

• the clamp is made without a key, but only by rotating the cartridge sleeve by hand;
• requiring additional compression using a special key, which is inserted into a recess in the chuck and rotates it, resting on a toothed rim, for example, as in a gear chuck.

How to remove the chuck from a screwdriver, for example, to lubricate it or replace it if it does not hold the attachment well. In modern models, the cartridges are screwed onto the shaft and secured with a screw with a left-hand thread for reliability. This is how the cartridges are attached in screwdrivers, etc. It is necessary to unscrew the screw and unscrew the cartridge by rotating counterclockwise. Detailed instructions on how to do this are available in the documentation for the tool.

How to use a screwdriver correctly and safely

Working with this tool is intuitive. But you need to know certain subtleties that reduce the risk of injury and tool breakage. So, how to tighten a self-tapping screw safely with a screwdriver:

1. Read the instructions carefully BEFORE using the tool for the first time, and not after something unpleasant has happened.

2. Correctly select the maximum torque at which the protective “ratchet” will operate and no force will be transmitted to the shaft. The tool is, of course, designed for maximum effort. But, firstly, constant operation at maximum reduces the service life. Secondly, the likelihood that the screwdriver can be torn out of your hands increases. Thirdly, by learning to correctly determine the maximum torque, you will reduce the likelihood of damaging the surfaces into which you screw screws. This is especially true for polished and fragile surfaces. For example, in the model the maximum torque is 30 nm, but you can set it to 5 nm.

3. Select the correct operating mode. There is no need to drill in the screwdriver mode, much less tighten the screws in the drilling mode, where the speed is higher. The tool may simply be snatched from your hands.

4. Don’t forget to control the direction of rotation. We tighten the screw - the cartridge should rotate clockwise, unscrew it - counterclockwise.

5. We do not change any cutting mode settings on the fly! This threatens to break the screwdriver and is unsafe.

Above we talked about the rules of safe operation that directly relate to the screwdriver. Now about the general organization of work with this tool:

• Work only with safety glasses and preferably with protective gloves, especially if you are drilling materials that can crack and “shoot out” sharp fragments.
• Before drilling, make sure that there are no electrical cables or other utilities in the area.
• When tightening and unscrewing screws, as well as drilling small-diameter holes, do not lean on the screwdriver. The screw or drill may break and you may be injured.
• and have different continuous operation times. In any case, it is there! And you shouldn’t bring the tool to a hot state.
• After work, you need to disconnect the battery, remove the attachment, and wipe the tool from dust.

A screwdriver does the same thing as a screwdriver, but hundreds of times faster. Therefore, if you need to tighten one or two screws, use a screwdriver. But if you need to assemble a wardrobe or, say, insulate a balcony with plasterboard, then you can’t do without an electric screwdriver. It is similar to an electric drill, but it drills with bits rather than drills. A bit is a special attachment for a screw, screw or self-tapping screw. Each self-tapping screw (screw, screw) has its own bit. It can be of different sizes.

A screwdriver is similar to an electric drill, but instead of a drill, it has a bit.

How to use a screwdriver?

The screwdriver is designed specifically for driving screws, self-tapping screws, and screws. Its great advantage is that it is self-contained, meaning there is no need for an outlet and the cords will not get in the way. It runs on a battery, which is charged from AC power via an adapter (the process of charging the battery is similar to the process of charging a mobile phone). After charging the battery, lightly pressing it, insert it into the handle of the tool.

The batteries are nickel-cadmium, nickel-metal hydride and lithium-ion. Which one should you choose? Nickel-cadmium is the cheapest, but toxic. Lithium-ion - environmentally friendly, but expensive. Nickel-metal hydride ones are intended for professionals who, as part of their duties, have to deal with repairs for a long time.

Replaceable tips, bits, are fixed in a three-jaw chuck manually no deeper than the top edge. To make it more convenient to hold the cartridge in your hands when attaching attachments, the cartridge is covered with ribbed rubber on top.

How to use a screwdriver? After the required attachment is installed, put a self-tapping screw on the bit, place it in the right place, press the screwdriver button - the self-tapping screw is tightened.

The screwdriver can be used as a stand-alone electric drill. You cannot drill with it for a long time, as the battery discharges quickly. But it is quite possible to make several holes in the profile or drywall.

And yet, the main purpose of a screwdriver is to tighten screws without drilling a profile. With a certain force, the self-tapping screw will drill through both aluminum and even steel profiles.

On the tool, if necessary, there is a button for smoothly changing the speed and a reverse button if you need to unscrew the screw back.

Safety precautions

The instructions instruct you to use a screwdriver after all settings have been made.

When the tool is turned on, you cannot adjust the frequency and direction of rotation of the tip (bit). It is necessary to protect the tool from water entering it. The room in which repair work will be carried out must be well lit.

This article is intended for those people who have very little knowledge in the use of construction tools.
We think a fairly large number of people begin their acquaintance with construction tools by purchasing them, and only then begin to figure out how to work with this tool. In addition, there will probably be teenagers or women among the readers of this article who have no idea what a screwdriver is or what can be done with it. It is for them that we decided to write this article.

So let's continue...

To begin with, let’s talk in general terms about what a screwdriver is. Firstly, they can be divided into two large classes: battery-powered and mains-powered. The effectiveness of these tools depends directly on the brand of the tool, but cordless ones do not depend on the presence of an outlet and the length of the wire.

For a home craftsman, it is best to choose a cordless tool - it is more convenient and practical. Let's start with it.

Typically, cordless screwdrivers are sold in cases that, in addition to the tool itself, include a pair of batteries and a charger. When purchasing, it is best to immediately check the completeness of the tool and its functionality in the store. It is necessary to understand that the screwdriver is supplied uncharged from the factory, so when you bring it home, you must first charge the batteries using a charger.

After this, we insert one of the batteries into the tool and it is almost ready for use. To work, we still need to insert one more element into the chuck - the necessary bit or drill. You can buy a set of bits and drills in the store, or you can buy them separately, the same for drills.

Modern screwdrivers, except perhaps low-power models, have the function of drilling and hammer drilling, so with their help you can also drill holes in metal and wood, as well as concrete and brick.

Before using a screwdriver, you must check the integrity of the tool. There should be no mechanical damage such as dents or cracks on the case and batteries. The tool cannot be used with such damage.

Drilling metal and wood with a screwdriver

In order to make a hole in metal or wood, you need to place an appropriate drill in the chuck. For wood, if necessary, a metal drill is also suitable. After this, you need to set the desired mode - drilling. This is done using the rotating part of the tool, located immediately behind the screwdriver chuck. On the markings located on the screwdriver body, find the image of the drill and align the rotating part (arrow) with its image. In this case, the screwdriver will switch to electric drill mode. This mode must be used with caution. The fact is that the tool’s so-called ratchet is turned off (protecting the engine from excessive force on the shaft). If the drill jams, the motor may burn out.

Next, place the drill at the drilling point and press the start button. While drilling, it is important to hold the screwdriver perpendicular to the drilling axis. Due to misalignment of the drill, especially in hard material, the drill may break off. We drill harder materials at low speeds, and soft ones, such as wood, at high speeds. By the way, if the screwdriver has a speed switch button (usually two speeds), then it is best to drill at the second speed. During the drilling process, we control the pressure force ourselves. Unfortunately, it is difficult to explain this in words, so you can determine this parameter through practice.

Drilling concrete and stone with a screwdriver

To drill holes in concrete and stone, we need a special drill with a Pobedit tip. Usually everyone uses a drill with a diameter of 6 mm, which fits most plastic dowels for self-tapping screws. You shouldn't take a thicker drill - the power of the screwdriver is simply not intended for this - a hammer drill is needed here.

Before drilling, switch the screwdriver to hammer drilling mode, similar to that described above. To do this, combine the guide arrow with the image of a drill made from sections or a drill and a hammer (depending on the brand of the tool). Just as in the previous case, hold the tool perpendicular to the drilling axis. There is no need to press the tool very hard during the drilling process, although it should be sufficient to gradually deepen the drill. We periodically loosen the pressure and even remove the drill from the hole to remove drilling products (dust).

Tightening screws, self-tapping screws and bolts with a screwdriver

Well, finally we come to the main purpose of screwdrivers - driving screws (which is where its name comes from). On each screwdriver (on the rotating part) there is a series of numbers around the circumference: 1, 2, 4, 6, 8, etc. They indicate the tightening torque in Newtons. The thicker the screw or self-tapping screw and the harder the material in which it is wrapped, this figure should be higher. To wrap, for example, roofing screws into metal, a force of 12–14 N is usually sufficient.

To screw standard self-tapping screws into wood, 8 N is enough. Again, this force is selected individually for each type of screw and base material. It’s better to start tightening a new type of screw by setting the force value lower, then you can add force and tighten it. But if you immediately apply a lot of force, you can twist the self-tapping screw, which will lead to the head of the self-tapping screw breaking off, or twisting (the self-tapping screw or screw will push through the material being fastened).

Depending on the head of the screw or screw, you will need a variety of bits. For standard self-tapping screws, the bit is PZ2, for small self-tapping screws, the bit is PZ1, but for roofing screws, the head is 8 mm. It is also very convenient to assemble cabinet furniture using a screwdriver. If you have a bit for confirmation (euro screw), then the speed of furniture assembly will increase several times. In addition, it will do without calluses on the fingers from manually twisting a large number of confirmations.

The mode for driving screws and self-tapping screws has one very good property. If the base material turns out to be too hard and the screw jams during tightening, the so-called ratchet will work. A special mechanism will stop the transmission of rotation from the engine to the bit, which will prevent damage to it. All this is accompanied by a characteristic crash. You shouldn't be afraid of him.

By the way, in the twisting mode you can easily drill wood without changing the mode, the drill goes through quite easily. If the force on the tool is not enough to tighten the screw into solid material, experienced craftsmen switch the screwdriver to drilling mode and tighten the screw. But we do not recommend doing this, since you can simply burn out the electric motor without the necessary experience.

While tightening, it is necessary to press the bit against the head of the screw with sufficient force so that the bit does not slip. If the edge slips, the bits get licked and it fails.

At the end of the article, we note that it is best to store an electric screwdriver in a dry, heated room. Due to humidity, the contacts of the tool will oxidize and it may fail. Screwdriver batteries must be stored in a charged state. This way they will last much longer. If the batteries no longer hold a charge, you can always order new ones from service centers.

We hope our instructions helped you in your work and were useful.

A screwdriver is a tool with which you can quickly screw in fasteners (screws, self-tapping screws, screws); it is used to assemble furniture, hang shelves, drill holes, install a suspended ceiling or lathing. To understand how to use a screwdriver correctly, it’s worth learning more about how it works and what kind of work can be done with it.

Types of screwdriver

Modern devices are divided into subtypes that differ in functionality.

Exist:

• screwdrivers, with which you can only tighten fasteners;
• wrenches used for tightening hexagons;
• cordless screwdrivers are the least powerful simple tools;
• drills and screwdrivers, also used for drilling holes.

Depending on the type of power supply, devices can be battery-powered or mains-powered. The former are considered more convenient because they allow you to work away from outlets, including on the street.

Screwdrivers can be with a key chuck for fastening the drill or with a quick-release chuck.

Tool selection

The most important indicators that you should pay attention to when purchasing are the rotation speed and power of the screwdriver.

The rotation speed affects the functionality of the device. Tools whose speed does not exceed 350 rpm are suitable for tightening or unscrewing fasteners. Drilling will require devices with a rotation speed greater than or equal to 1000 rpm.

If you plan to purchase a cordless screwdriver, you should find out its type. The most common devices are those with lithium-ion cells, which have a long service life. It is recommended to choose them if the device will be used frequently.

If work using a screwdriver is rare, a nickel-cadmium cell is more suitable - they are cheaper and are not as prone to self-discharge as lithium-ion ones. Network-powered devices are also suitable for exclusive home use.

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

• work area lighting;
• a torque boost pulse used to recess fastener heads;
• impact mechanism;
• increase in rotation speed.

Design

The tool consists of a housing in which the motor and gear mechanism are located; chuck (clamp for replaceable drills); battery or cord to connect the device to the network.

Preparing for work

Before using a screwdriver, you need to select a nozzle that fits the size of the head of the fastener. To install it in a tool with a quick-release chuck, push the attachment between the jaws and turn the sleeve clockwise. To fix the nozzle in a device with a key cartridge, insert the key nozzle into the socket and turn it clockwise until it is secured.

A device equipped with a battery should be charged, and a device powered by the mains should be plugged into an outlet.

To make sure that the screwdriver is working properly, first turn it on idle. Check whether the direction of rotation of the nozzle corresponds to the direction of the fastener thread.

Screwing in and tightening fasteners

The instructions for using the device are simple:

1. The tip of the nozzle is inserted into the slot of the self-tapping screw or screw, and the device is turned on.
2. To increase or decrease the twisting speed, increase or decrease the pressure on the start button.
3. When the self-tapping screw is tightened, the force limiting mechanism will automatically work, after which the work will stop.
4. To unscrew the screw, the nozzle is placed in the slot, having previously set the lever for the direction of rotation of the nozzle in the opposite direction.

Features of operation

Incorrect operation and breakdowns may occur after switching tool operating modes while the chuck is rotating. To prevent this from happening, it is recommended to perform all operations only after turning off the screwdriver and stopping the engine completely.

It is also necessary to correctly select the torque of the device, taking into account the hardness of the material being worked with:

1. Fiberboard and drywall. To tighten self-tapping screws into these materials, use 1–4 modes.
2. Hardwood. The regulator ring is moved to the maximum value.

Important! It is better to set a lower torque value than required. If you select an overestimated value, after tightening the self-tapping screw, the screwdriver chuck will continue to rotate and will not stop as expected. The spline will be damaged.

You can only use a screwdriver as a drill for a short time. When using a tool that is not intended for drilling for a long time, the electric motor may overheat, which will lead to damage to the device.

Safety regulations

• Do not allow moisture, sand and construction dust to get inside the tool.
• The room in which work takes place must have high-quality lighting. If you are using a screwdriver powered by electricity, you should make sure that the network is stable and there are no voltage drops.
• Switching operating modes is carried out only when the tool engine has completely stopped, in the off state.
• If the tool begins to work with force, the speed of rotation is reduced or turned off for a while.
• Do not touch grounded objects with the device: the worker may receive an electric shock.
• In order for the screwdriver to work properly, the chuck is regularly lubricated and cleaned of dirt.

Knowing how to use a screwdriver correctly, you can avoid making common beginner mistakes, which significantly reduce the service life of the device and sometimes lead to complete failure of the tool.

How to use a screwdriver?

It often happens that you can’t do without a screwdriver. A screwdriver is an indispensable assistant in the manufacture of suspended ceilings and installation of drywall. Repair work becomes more complicated if you don’t have a screwdriver on hand that can easily tighten screws and fasteners. In the domestic sphere it is in demand no less than in professional activities.

However, not all tool owners know how to use a screwdriver correctly. There is nothing difficult about this, the main thing is to adhere to some rules and recommendations for beginners.

Types of instruments: characteristic features

Screwdrivers can be classified into the following types:

1. Drill/driver
2. Impact wrench
3. Cordless screwdriver
4. Standard screwdriver

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

A drill-driver can not only tighten a screw, but also drill a hole. The impact wrench specializes in bolts and nuts. The third representative is a cordless screwdriver, designed exclusively for screwing/unscrewing fastening elements with a cross-shaped head. The latter type is characterized by low power, unlike the above.

What does a screwdriver consist of? Device setup.

The plastic case contains a motor and a gear mechanism that drives the bit, which is installed at the end of the screwdriver. The device is equipped with a start toggle switch, a direction and speed switch, LED backlighting and a tightening time regulator.

The operating principle of the tool is very simple. The nozzle, previously fixed in the cartridge, moves with the help of a shaft, which begins to move from the operation of the motor through a gearbox. Before using a screwdriver, you should find out whether the battery is charged and whether the correct attachment is installed.

Immediately before performing the work, you need to look for a nozzle so that it matches the head of the self-tapping screw or screw.

To install the required nozzle, you should select it according to the size of the head of the fastener element and secure it in the magnetic holder of the cartridge. First, the chuck with the coupling must be removed from the device, and after fixing the bit, the chuck must again be secured to the screwdriver body.

Then you need to assign a suitable bit speed. The setting is performed using a special regulator. The required mode is set when the instrument is turned off.

Before using a power tool, it is necessary to adjust the screwing depth of the fastening element. After some time, it may be necessary to replace the magnetic holder. To change it, remove the cartridge, magnetic mount and coupling. Next, the chuck with the coupling is fixed back into the screwdriver block housing.

After the required attachment (bit) for the drill has been selected, taking into account the size of the screw head and the configuration of the recesses (straight, cross), it must be installed in the very center between the open cams, and secured in the chuck by turning the sleeve in a clockwise direction. If a key type chuck is selected, then the key is installed in the recess on the chuck and then rotated clockwise until the nozzle is secured. The end of the nozzle is placed in the groove of the screw. Before starting the device, check the accuracy of setting the direction of rotation; the direction must coincide with the tightening of the screw.

Increasing pressure on the start button regulates the optimal rotation speed. When the screw is fully immersed, the force limiting mechanics are activated and then the drill stops.

After completing all the settings, you can start using the power tool. By studying the operating instructions for the screwdriver, you can prevent possible malfunctions during handling of the device, thereby increasing the service life of the tool.

It is not allowed to adjust the frequency and direction of rotation of the nozzle when the device is turned on. Do not touch grounded objects with power tools, otherwise a person may receive an electric shock. Do not use the device for a long time as it may burn out.

The room in which it is best to use a screwdriver should be well lit, and the power supply should be constant, without surges, this will avoid equipment malfunctions. Work must be carried out in specialized clothing and only with working tools.

Can a drill be used as a screwdriver?

A screwdriver can also be used as a drill. The chuck mechanism makes it possible to firmly fix a drill with a cylindrical shank. To get started, you will need to install a drill in the chuck.

Be careful, as the design is not designed for making holes, especially for hard wood, metal or concrete, because there is a high probability of the planetary gearbox breaking.

Screwdriver maintenance + (Video)

There is nothing remarkable in maintenance, since today modern models have increased strength and can even withstand falls from a small height. The chuck should be lubricated and cleaned regularly. Avoid getting moisture, dirt, sand into the middle of the instrument. Watch the screwdriver overload; if you feel that the screwdriver is starting to work with force, reduce the speed.

Design and purpose of power tools

A screwdriver is used to tighten and unscrew various fasteners. The tool can cut threads and drill. It greatly facilitates and speeds up the work. Screwdrivers are used in everyday life, construction, furniture assembly, in auto repair shops, anywhere where you need to work with a large number of fasteners.

The screwdriver can be cordless or corded

Main elements of a screwdriver:

1. Cartridge.
2. Torque control clutch.
3. Speed ​​shifter.
4. Motor in the screwdriver housing.
5. The gearbox is enclosed in the tool body.
6. Reverse switch.
7. Power button.
8. The handle is rubberized to prevent slipping.
9. Battery.
10. Power cord.

Screwdrivers are powered by batteries or mains.

Types of bits for a screwdriver: how to choose

To choose the right nozzles, you need to study their varieties. First determine the shank shape type and diameter. It ranges from 1/4 to 1 inch.

Shank classification:

• basic;
• special;
• combined.

Types of main bits:

Types of special bits:

Combination bits have two types of shank shapes or one, but of different sizes. For example, a splined shank and sprocket.

Example of a combination nozzle

Splined shank and sprocket

Determine the length of bit you need for the job. It ranges from 10 to 200 mm.

Depending on the shape of the shank, the nozzles have a certain marking:

• Sl (Slot) – splined;
• Ph (Philips) – cross-shaped universal;
• Pz (Pozidrive) – cruciform with additional thin ribs;
• T (Torx hole) – sprockets;
• H (Hex) – hexagonal.

An important characteristic is the grade of steel from which the bat is made. The nozzle may have a protective coating. The strength of the equipment depends on this. The main types of steel and coatings that should be preferred:

Nozzles vary depending on the purpose:

• twisting and unscrewing;
• drilling;
• riveting;
• polishing;
• milling.

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

How to work with attachments

Screwdrivers have different cartridges. Let's look at how to change the nozzle in all types.

Magnetization and hardening of attachments

A large number of nozzles are made in China from soft material. Therefore, they quickly lose their shape. A new bit doesn't last long. To extend its service life, the nozzle must be hardened. You will need: machine oil, a gas burner or gas stove, a small container for oil from any tin can, a piece of steel wire.

A hardened bat will last longer than a regular one.

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

Method 1

You will need to purchase a special screwdriver. Insert the bat there. A square window magnetizes, while a stepped window does the opposite.

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

• Before connecting and removing the battery, turn off the screwdriver;
• do not allow the instrument to overheat, take breaks;
• adjust the torque control clutch correctly;
• after using high speeds, set the minimum speed and idle the engine for several minutes to cool it down;
• Check the cable of the mains screwdriver, and for the battery, check the power cord of the charger. If a tool or charger periodically loses power, the wire must be replaced;
• Do not use the screwdriver in rain or snow. In humid environments, you can only work under a canopy.

How to regulate speed and force

The rotation speed is changed by a switch located on the screwdriver body. High speed is used for large bolts and screws, as well as for drilling, if such a function is present.

Speed ​​shifter

Many models have a force limiting clutch. Its presence in a power tool can be determined by a rotating ring with numbers. Some users do not understand the meaning of the clutch and do not touch it. Using a ratchet, you can adjust the depth of screwing in the screw. If the material is too soft, the head of the fastener is easily recessed and can pass right through. When using small fasteners, very high torque can destroy it. The ratchet prevents the slots of the screws from being cut off and the screwdriver bits from wearing out. To determine the desired value on the adjusting ring, make several passes, starting with the minimum. For drilling mode, maximum torque is used. But only if such a function is available.

Force limit clutch

The start button also regulates the rotation speed, but no more than that set by the switch. Let's say you set the switch to the first speed, which is stated to be up to 800 rpm. Pressing the trigger as hard as possible will not increase the speed. And the torque in maximum mode will be low, that is, you will not be able to tighten large screws and drill. And if you set the switch to maximum speed, you will be able to drill and the speed will be much higher.

Adjust speed, torque and reverse when the tool is off.

Tool Usage Options

A screwdriver can not only tighten and unscrew fasteners. So that the tool does not lie stale, it can be found in many applications.

Can a screwdriver be used as a drill?

You can drill with a screwdriver only if this mode is provided by the manufacturer. Then drilling will be safe. Read the instructions carefully. On the coupling this is the last position or the drill icon.

Drilling mode designation

In screwdrivers with a drilling function, a quick-release or key chuck is installed. A magnetic or snap chuck will not hold the drill and ensure safe operation. To replace the equipment, do the following:

Other uses

Using various attachments, the tool can perform the following work:

You can still find many uses for this tool. But remember that you need to wear protective glasses and gloves when working.

Care and storage

• regularly disassemble and clean the internal elements of the screwdriver from carbon deposits, dust and dirt;
• If unstable operation occurs, carry out diagnostics. Check the wear of the brushes so that you do not have to change the motor armature;
• Do not leave the instrument in areas with high humidity or under the sun. The same goes for the battery;
• Do not keep the battery near keys, coins or other short metal objects. In case of accidental contact with the poles, the battery will short circuit. As a result, a fire may occur;
• At the end of the working day, take a clean rag and wipe the instrument. The cloth can be slightly moistened with water without using detergents;
• The screwdriver should be stored in a dry environment with positive temperatures. Use a case or other packaging to prevent the instrument from becoming covered in dust.

Operate a screwdriver, observing safety precautions and the rules described in the instructions. Choose the right equipment. And then the tool will serve you for a long time.

Instructions: how to use a screwdriver

The word “screwdriver” is present even in the vocabulary of kindergarten children. By trying on a construction helmet and picking up toy tools, they begin to become familiar with their purpose. Even children understand that they cannot do without a screwdriver if, for example, they need to hang a picture in a room or replace a damaged door lock. But not every adult knows how to use a screwdriver.

A screwdriver is used in woodworking, metalworking, and also when it is necessary to prepare a small hole in a concrete wall; if larger-scale work is required, it is better to use a drill or hammer drill.

Screwdriver and drill: subtle differences

The presence of a plug indicates a drill, and the battery indicates a screwdriver. This is usually the answer given by ordinary people when they are asked about the distinguishing criteria of these instruments. It is incomplete and not entirely correct, since you can use a screwdriver by connecting it to the mains.

Those who are more attentive, have seen and used this tool, point out that it quickly stops working - immediately when you press the corresponding button. The reason is the run-out brake, which the drill does not have. Even when it is turned off, the chuck still moves and can damage the screw.

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

As a buyer, you need to evaluate the ease of use of the tool. It's nice if it has a fastening loop. This small device should be used when the tool is not in use.

You can read how to use a screwdriver in the instructions that came with it. But even more important will be the decision to diligently study the structure of this device and only then, following the recommendations, accurately assemble it. For example, after replacement, a screwdriver chuck must be securely secured with a special screw. If there is an error, then already during the starting start it can jump off the shaft making rotational movements. Then you will have to correct this problem or even contact a traumatologist.

In addition, when assembling the tool, you need to be careful with the electric motor. An incorrectly installed switch and more pinched wires than necessary can cause the screwdriver to break.

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

If you want to test this device by using it as a drill, then high speeds are necessary. That is why in this case it is necessary to use a screwdriver for a short time. As an alternative, another method is used: reducing the rotation speed.

Correct attachment – ​​effective results

Which nozzle to choose in order to perform the task most effectively, you need to think in advance. You need to work with wooden materials, but you took a drill for metal - the result may upset the initiator of the repair. It happens that the drill has to be replaced. A screwdriver can be used when you need to prepare a small recess in a wall made of concrete. But if global work is ahead, then you should use an impact drill. A hammer drill will also come in handy here.

If you buy special attachments (bits) that are inexpensive, then the bolts, nuts and self-tapping screws may not be tightened very well. Usually, cheap models do not have a working notch located on the working area. The material from which the bits are made must be durable. Otherwise, this unpleasant situation will arise: you don’t use the tool for long, but you turn it slightly incorrectly and you find ground down edges. The solution is to replace the nozzle.

When choosing bits, there is no need to skimp on their additional properties (magnetic), which have their advantages when working in hard-to-reach areas.

After choosing a bit, you need to configure the tool correctly. In this regard, you need to understand how the spindle rotation course changes: here you pay attention to the switch.

The exact depth to which the self-tapping screw needs to be screwed is adjusted using a chuck.

A screwdriver needs breaks

In order for a screwdriver to serve its owner for a long time, it is necessary to use it correctly and remember: while loading the mechanical parts of this construction tool to the maximum, you should not count on long-term and at the same time effective work. If the electric motor operates at maximum speed, it can overheat and lead to malfunctions in the winding. Special attachments also have a hard time: when they come into contact with the materials intended for processing, they heat up. That’s why experts recommend taking breaks periodically to cool the drill. This problem should not be solved with water: sudden changes in temperature are undesirable.

The compilers of the instructions for the tool warn: adjusting the course of rotation of the bit, its frequency is prohibited if the screwdriver is turned on. Where this device will have to be used, sufficient lighting and stable operation of the electrical network are required.

You must be careful if grounded objects are nearby. It is strictly forbidden to touch them with a screwdriver; an electric shock will not be pleasant for anyone. While protecting himself, a person must also treat the instrument with care. For example, it is necessary to ensure that the housing is not threatened by moisture.

Use the screwdriver carefully. It is easy to prepare holes in a concrete surface, but you should not be negligent about your lungs and bronchi. Without special protection (here this role is played by a respirator), it is better not to undertake this repair operation. Glasses will also help to prevent small foreign particles from entering the sensitive area of ​​the eye.
