Each person at least once in his life made repairs at home or performed work related to the repair of his apartment or cottage. Today, an indispensable assistant in the repair is a screwdriver. When buying it, be sure to find out the power, equipment, as well as the warranty period for this power tool.
Safety
Before using a screwdriver, be sure to read the safety precautions in the instruction manual that came with the tool. Often this tool is used in production. As a rule, the instruction "How to use a screwdriver" must be mandatory in labor protection acts. To prevent accidents, when working with a screwdriver, you must follow all safety regulations. Do not trust the tool to people who do not know how to use a screwdriver and cannot follow safety precautions. For example, children, the elderly, sick people and people in a state of intoxication.
Use this tool while wearing overalls and goggles. Remember that any tool, whatever it may be, is a source of danger.
How to use a screwdriver battery
Before starting work, make sure that the battery of your screwdriver is fully charged. Insert it into the charger and pay attention to the indicator. Green indicates that the battery is charged. The red color of the indicator indicates that it needs to be charged.
In order to increase the operating time of the screwdriver, it is enough to have a second battery. After the first is discharged and you replace it with the second, insert the first into the charger. After the battery is charged, do not keep it in the charger. This shortens the life of the battery as a whole. Also, too hot or too cold room temperature in which the screwdriver works has a detrimental effect on battery life. One battery lasts for five hours.
How to fix a bit or drill
There are two ways to fix a drill or bit in a screwdriver. The first way is manual. The bit is inserted into the chuck and tightened by hand. The second way is to tighten the bit or drill with a rotating chuck, hold it with your other hand. Checking how you secured the bat is very simple. Try to tighten one self-tapping screw, and you will understand whether the bit scrolls or not.
How to use a screwdriver correctly
The screwdriver has a scale with which you can adjust the direct power of rotation. Turning the knob, you select the mode that you need, depending on the work that you intend to do. The same knob can be used to select the drilling mode. Just do not try to drill hard, concrete and stone surfaces with a screwdriver, so as not to disable it. For drilling hard surfaces, there are tools specially designed for this. Do not switch the regulator while the screwdriver is in operation. This may cause the instrument to malfunction. By knowing how to use a screwdriver, you can extend its life.
Three operating modes can be selected using a dedicated switch. Tightening mode, unscrewing mode and screw gun blocking mode. The third mode is needed for security. All these modes are very convenient to switch if you hold the screwdriver by the handle located above the battery. The handle is usually covered with a rubberized material and is therefore very safe to use. It ensures that the screwdriver does not slip out of your hand at the most inopportune moment. For greater confidence, you can fasten a screwdriver to your hand with a special strap.
Drill mode
If you decide to use a screwdriver as a drill to drill a hole in wood or plastic, then in order for the hole to be of high quality, you need to place an even piece of wood under the objects you are drilling. So you can avoid cracks and chips when drilling.
In metal, it implies compliance with certain rules. The place of the future hole must be punched. This will help prevent the drill from slipping on the metal surface. Having chosen the drilling mode on the screwdriver, do not forget that when drilling metal, drills often break at the exit from the metal. To avoid this, try not to press hard on the screwdriver while drilling. If the drill is stuck, then switching the screwdriver to the unscrewing mode will help to unscrew it. If you are drilling a small piece, use a vise to hold it.
Screwdriver application
Those models of screwdrivers that are sold today in stores allow you to pick up a bit for a self-tapping screw so that they fit tightly to each other. And setting up a screwdriver so that the tightening of each screw is perfect has become very simple.
Do not think that a screwdriver can only be used to drill, tighten and unscrew screws. When repairing a car, you can unscrew and tighten nuts and bolts, grind surfaces with a variety of nozzles. Assembling furniture without using a screwdriver will take a lot of time. Hanging curtain rods or bookshelves with a screwdriver is much easier than running around with a screwdriver and putting in effort. So today, a screwdriver has taken its place of honor among the most necessary tools in the household.
Tool Care
Timely cleaning of the screwdriver with a soft cloth will extend its service life. Keep the screwdriver away from water and moisture. Store in a dry place. Don't drop the screwdriver. Trying to handle the screwdriver carefully, also keep an eye on the charger and its cable for connecting to the mains. If you notice both a malfunction in the operation of the screwdriver itself and a malfunction in the operation of the charger, then try to contact the service center. Turning to specialists, you will receive high-quality repairs and high-quality spare parts, which will significantly extend the life of your screwdriver.
The popularity of the question of how to insert a drill into a hammer drill or an electric drill is explained quite simply: such devices are actively used both in industrial and domestic conditions.
An incorrectly installed drill can lead to a number of problematic situations:
- inability to work with a puncher or drill;
- obtaining uneven holes with a broken inner surface;
- drill stick out, which could result in serious injury.
Despite the fact that it is not so difficult to insert a drill into a puncher or drill, this issue should be approached responsibly.
Correct installation of the drill in the drill chuck
Before you figure out how to properly install a drill into a hammer drill, it is advisable to figure out how to insert a drill into a drill. An element of its design, in which the drill shank is fixed, is a chuck. On most models of modern drills, cam-type chucks are installed, consisting of:
- cylindrical body;
- rings or sleeves that rotate around the outer surface of the housing;
- cams installed in the inside of the housing.
When the sleeve is rotated clockwise, the cams simultaneously approach each other, thereby reliably clamping the shank of the installed drill. Accordingly, the question of how to pull the drill out of the drill is not difficult to solve: just start rotating the sleeve counterclockwise. In this case, the cams will begin to diverge, which will make it easy to remove the drill from the drill. It should be borne in mind that before installing the drill, the cams should be unclenched with a margin, in which case the tool can be easily inserted.
The convenience of using cam-type chucks lies not only in the efficiency and high reliability of tool installation, but also in the fact that drills of almost any diameter can be inserted into them. When using such cartridges, as a rule, there are no difficulties with how to change the drill in a drill. A correctly inserted tool is held securely in such chucks and allows you to drill a precise hole.
If you begin to notice slippage of the teeth when tightening the cartridge, replace the worn key with a new one.
Cam chucks are used in both industrial and domestic drilling tools. Clamping devices for household drills are available for two ranges of drill diameters: from 0.8 to 10 and from 1.5 to 13 mm.
The design of cam chucks can provide two different ways of clamping the tool: key and quick-clamping.
In the first case, the sleeve is actuated using a special key, on the conical working part of which there are teeth. The key to actuate the clamping mechanism must be inserted into the holes on the side of the chuck body and rotated. There may even be three such holes in individual models. Accordingly, in order to loosen or tighten the cams, the key must be inserted into each of them and begin to rotate counterclockwise or clockwise.
After loosening the cams with a key, it is necessary to turn the cartridge itself counterclockwise, which will increase the distance between the cams to the required value. The inserted tool is fixed in the reverse order: first, the cartridge itself is clamped (when it is rotated clockwise), and then the sockets are clamped with a key.
Pulling out and installing drills when using a keyless chuck is much easier and faster. In it, the sleeve is actuated by manually rotating it. To limit the pulling force of the cams, they are often equipped with blocking elements.
Before inserting a drill, first make sure that the drill is in working condition and disconnect it from power. Only after that you can start installing the drill.
Installing a working tool on a puncher
As mentioned above, the hammer drill must be checked for performance before installing the drill. To perform such a check, the working mode of the rotary hammer is set to drilling without a fight. If, after pressing the start button of the device, you hear and feel that its engine runs smoothly and without jerks, then the hammer drill can be used for its intended purpose, after inserting a drill or drill into it.
Before inserting the drill into the punch, it is necessary to treat the shank of the working tool with a special lubricant that will protect it from corrosion. The procedure for installing a drill into a puncher is as follows.
- The back of the puncher is mounted on the floor or other hard surface.
- The movable part of the clamping device is pulled back.
- The tool is inserted into the puncher until it stops. In this case, the drill or drill, which must be inserted into the punch, must be held vertically. If you neglect this requirement, you may encounter the fact that the tool will fly out or even break, and this may also lead to failure of the punch itself.
Considering the fact that the chucks on modern rotary hammers differ in a fairly simple principle of operation, as a rule, there are no questions about how to get a drill from a rotary hammer.
Having removed the used tool from the puncher in order to replace it with another, it is advisable to immediately clean its shank from grease and construction dust. In this case, the drill shank that you are about to insert must also be cleaned and pre-lubricated. The tool replaced in this way will not harm the clamping mechanism of the hammer and will last much longer.
Using a puncher, you can not only get a drilled structural element, but also perform processing with a special chisel. You can also install a mixer as a working body of such a device.
Home craftsmen often also have questions about how to insert a drill into a screwdriver or how to change a cartridge on a hammer drill. Solving the first question is quite simple, since the design of the screwdriver uses cartridges of the same design as on drills and rotary hammers. But the question of how to properly replace the cartridge on a puncher should be approached with skill: it is not easy to perform such a procedure without certain knowledge and skills.
In order not to face the fact that a flying tool or concrete chips will harm your health, drilling work must be carried out in compliance with all safety measures. Protective goggles, gloves, earplugs or hearing protectors should be used as safety measures. Naturally, all work must be carried out in special clothing, in which there should not be hanging elements that can be wound around the drill.
To prevent overheating of the electric tool used for drilling, it is necessary to regularly rest it. It is very important to insert the drill correctly (you need to do this until the tool stops).
What is a screwdriver? In fact, this is the same drill, but the screwdriver differs from it in that it has a lower chuck rotation speed and, at the same time, more torque.
Another difference is that if the rotation speed on a drill can change smoothly, then on a screwdriver, as a rule, “fixed” chuck rotation speeds are set. This is due to the “slip” function of the screwdriver chuck: when the screw is tightened, the chuck stops rotating, although the engine is still running. This feature allows you not to break the slots and not to “drive” the screw inside.
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 allow them to perform a wide range of work: tightening and loosening screws and self-tapping screws, screws and nuts, drilling soft materials.
The use of a screwdriver, for example, in the production of plasterboard partitions or in the assembly of furniture, increases the speed of work at times. Therefore, a screwdriver is rightfully considered one of the most common tools in the set of any master.
The designs of all screwdrivers are approximately the same. They are quite light and have a "pistol" handle, designed to work with the tool with one hand. The start key is designed in such a way as to control the rotation speed by pressing it.
An important element of a screwdriver is its power source. If drills are available in versions both with mains power and in an autonomous (battery) version, then screwdrivers, due to the nature of the application, are almost exclusively cordless. The battery is the heaviest and most expensive part of the screwdriver.
Household models of screwdrivers are usually equipped with nickel-cadmium (they are designated "Ni-Cd"), and more expensive professional models are equipped with lithium-ion ("Li-Ion") batteries. Their difference lies in the fact that nickel-cadmium ones have a shorter service life (about 1000 recharges), and also have one unpleasant feature: if the battery is not completely discharged, its capacity decreases during subsequent charging.
But whatever the battery, its capacity is limited by the weight of the tool. Therefore, even the most expensive models of screwdrivers are able to work continuously for no more than a few hours. Some manufacturers solve this problem by adding a second spare battery to the screwdriver set. However, this significantly increases the cost of the tool. The battery is charged from a regular network. The charging speed again depends on the model and can range from 2-3 to 6 hours, although some models of screwdrivers provide for a “fast” charge in 10-15 minutes.
Work rules
Working with a screwdriver is easy. The nozzle necessary for work (“bit”, or wrench, or drill) is clamped in the jaws of the cartridge, and, pressing the screwdriver with some force, pressing the button rotates the cartridge. If you need to unscrew the screw or pull out the drill, the “reverse” is turned on. When working, you should follow a few rules:
- Before using the screwdriver, fully charge it. At the same time, strictly follow the instructions for charging time - "overexposure" of the battery in the charger reduces its service life.
- When working, choose the “screwing” or “drilling” mode correctly - this way you will protect the engine and screwdriver gear from damage. Remember that the screwdriver is not designed for drilling stone or concrete.
- Try not to throw or drop the screwdriver - it is a rather fragile tool.
- Keep the screwdriver clean - remember that fine dust and dirt particles act as an abrasive in the rubbing parts, and the elements of the screwdriver fail faster.
- Now you have a general idea of what a screwdriver is and how to work with a screwdriver. It's time to take the tool in hand and create!
A screwdriver often replaces a conventional screwdriver. Many models are equipped with a drilling function. In each case, you need to correctly select the equipment and use it correctly so as not to damage the tool and fasteners.
The device and purpose of the power tool
Screwdriver is used for twisting and unscrewing various fasteners. The tool can cut threads and drill. It greatly simplifies and speeds up the work. Screwdrivers are used in everyday life, construction, furniture assembly, in auto repair shops, wherever you need to work with a large number of fasteners.
The main elements of a screwdriver:
- Cartridge.
- Torque control clutch.
- Speed shifter.
- Screwdriver motor.
- The gearbox is enclosed in the tool body.
- Reverse switch.
- Power button.
- The handle is rubberized to prevent slipping.
- Battery.
- Network cord.
Screwdrivers are powered by batteries or from the 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 comes in 1/4 to 1 inch.
Shank classification:
- basic;
- special;
- combined.
Types of basic bits:
- slotted. They differ in the width and thickness of the slot;
- cross. They have a different angle at the base and shape;
- hexagonal. The main characteristic of the bit is the distance between the sides of the hexagon;
- tetrahedral;
- asterisks. This shape improves the adhesion between the nozzle and the fastener.
Types of special bits:
- tri wing or trihedral;
- double pin. Similar to slotted ones, but with a notch in the middle;
- torq set. Like trihedral, but with four rays;
- end. Usually performed with a magnet;
- for drywall. Have a persistent limiter;
- with spring lock.
Combined bits have two types of shank shape or one, but of different sizes. For example, splined shank and sprocket.
Combination nozzle example
Determine the length of the 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) - slotted;
- Ph (Philips) - cruciform universal;
- Pz (Pozidrive) - cruciform with additional thin ribs;
- T (Torx hole) - sprockets;
- H (Hex) - hexagonal.
An important characteristic is the steel grade from which the bit is made. The nozzle may have a protective coating. The strength of the tooling depends on this. The main types of steel and coating, which should be preferred:
Nozzles vary depending on the purpose:
- twisting and unscrewing;
- drilling;
- riveting;
- polishing;
- milling.
Given all the parameters considered, you can easily select the necessary bits.
How to work with nozzles
Screwdrivers are equipped with different cartridges. Consider how to change the nozzle in all types.
- quick release chuck. There are single and double sleeves. Installed most often. To open the jaws and remove the old bit, rotate the front clutch counterclockwise. Insert a new bit and screw the sleeve back;
- hex chuck with magnet. The nozzle is simply inserted and pulled out;
- snap fastener. Found in pneumatic screwdrivers. The nozzle is inserted and snapped into place. To remove, pull the bit while holding the head of the clamp.
Magnetization and hardening of nozzles
A large number of nozzles are made in China from soft material. Therefore, they quickly lose their shape. The new beat doesn't last long. To extend the service life, the nozzle must be hardened. You will need: engine oil, a gas burner or gas stove, a small container for oil from any can, a piece of steel wire.
- Wind the wire around the bit so that it does not fall out.
- Pour oil into container. Ignite the gas in the burner and heat the bat red hot. Most importantly, don't overdo it.
- Dip the red nozzle into the oil for 5-6 seconds. Pull out for 2-3 seconds. Do this several times.
A hardened bat will last longer than a regular bat.

For convenience of work, especially in hard-to-reach places, nozzles are magnetized. This can be done in several ways.
Method 1
You will need to purchase a special device for magnetizing and demagnetizing screwdrivers. Put a bit in there. A square window magnetizes, while a stepped one does the opposite.

Method 4
As a result, the nozzle will magnetize the fasteners better than a new one.

After purchasing a screwdriver, follow simple recommendations for use. And then the tool will work for a long time and with high quality:
- turn off the screwdriver before connecting and removing the battery;
- do not bring the tool to overheating, take breaks;
- adjust the torque adjustment clutch correctly;
- after applying high speeds, set the minimum and rotate the engine idly for several minutes to cool it down;
- check the cable of the power screwdriver, and for the battery - the power cord of the charger. If the tool or charger periodically loses the network, then the wire must be replaced;
- Do not use the screwdriver in rain and snow. In a humid environment, you can only work under a canopy.
How to adjust the speed and effort
The rotation speed is changed by a switch, which is located on the body of the screwdriver. High speed is used for large bolts and self-tapping screws, as well as for drilling, if this function is present.
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 the self-tapping screw. In too soft material, the fastener head is easily recessed and can pass through. When using small fasteners, very high torque can destroy it. The ratchet prevents cutting the slot of the self-tapping screws and wear of the screwdriver bits. To determine the desired value on the adjusting ring, make several passes starting from the minimum. The maximum torque is used for drilling mode. But only if there is such a function.
The start button also controls the rotation speed, but no more than that set by the switch. Let's say you put the switch on the first speed, which is declared up to 800 rpm. Pressing the trigger to the maximum will not increase the speed. And the torque in the maximum mode will be low, that is, you will not be able to tighten large self-tapping screws and drill. And if you set the switch to maximum speed, you will be able to drill and the rpm will be much higher.
Adjust speed, torque and reverse when the tool is off.
Tool use cases
A screwdriver can not only twist and unscrew fasteners. So that the tool does not stale, it can find a lot of applications.
Can a screwdriver be used as a drill
Drilling with a screwdriver is possible 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 a drill icon.
In screwdrivers with a drilling function, a keyless or key chuck is installed. A magnetic or snap chuck will not be able to hold the drill and ensure safe operation. To replace a tool, do the following:
- In a double-sleeve keyless chuck, hold the rear sleeve and turn the front sleeve counterclockwise.
- If there is only one clutch, then turn it.
- The fists will open. Insert drill.
- Turn the sleeve counterclockwise to clamp the drill in the jaws.
- There are three holes in the key chuck. Insert the key into them in turn and turn until free rotation. The teeth of the key must engage with the teeth of the chuck.
- Rotate the chuck counterclockwise to open the jaws. Remove the old drill and insert the new one.
- Screw on the chuck first. Then tighten each hole with a wrench.
Other application
Using various nozzles, the tool can perform the following work:
- to polish;
- chamfer the bolts;
- work at any angle and in hard-to-reach places;
- sharpen knives;
- Safely and quickly tighten self-tapping screws with one hand. For this, a nozzle with a tape magazine of self-tapping screws is provided;
- install rivets;
- cut corrugated board with turbo shears;
- light a fire with a hair dryer.
There are many more uses for this tool. But remember that you need to work in goggles and gloves.
Care and storage
- regularly disassemble and clean the internal elements of the screwdriver from soot, dust and dirt;
- if you experience unstable operation, 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 high humidity environments or under the sun. The same goes for the battery;
- keep the battery away from keys, coins and other short metal objects. In case of accidental contact with the poles, a short circuit of the battery will occur. As a result, a fire may occur;
- at the end of the working day, take a clean rag and wipe the tool. The cloth can be lightly moistened with water without the use of detergents;
- you need to store the screwdriver in a dry environment with a positive temperature. Use a case or other packaging to keep the tool free of dust.
Work with a screwdriver, observing the safety precautions and rules described in the instructions. Choose the right equipment. And then the tool will serve you for a long time.
The screwdriver has successfully replaced not only various types of screwdrivers, but also wrenches, hex keys. Also, this tool is used instead of a drill. For builders with furniture makers, an electric screwdriver has become an indispensable tool. For him, and at home, there is always an application. The range on the market is represented by a wide variety of models. Despite the prevalence of screwdrivers in various fields of activity, not all users, especially beginners, know how to operate it. Proper use, maintenance and storage of your power tool will maximize its life.
According to the method of feeding, screwdrivers are divided into two types:
- network, connected to networks with a voltage of 220 V;
- rechargeable batteries that use the energy of the accumulated charge.
Recently, instruments with a combined power supply have also appeared. They combine all the advantages of both varieties.
The external and internal structure of network and battery models is almost the same. In general, a power tool consists of the following structural elements:
- corps;
- cartridge;
- power buttons;
- switch for the direction of rotation of the electric motor (reverse);
- speed controller (number of revolutions);
- power lock buttons;
- tightening force regulator (torque switch).
A number of models optional equipped with backlight, which is constructively realized in different ways. Not every product has a speed controller and a power-on lock button. Cordless electric screwdrivers have a power cord, while cordless electric screwdrivers have a charge accumulator installed instead.
Power tool housing most often made of plastic, much less often - from alloys of different metals. For convenience, it usually consists of 2 halves. Inside the case are the following main parts:
- electric motor (direct or alternating current);
- pay;
- capacitor;
- reducer;
- clutch.
The wiring diagram depends on the model.
The electric screwdriver can be equipped with different types of cartridges. The most widespread quick-clamping three-jaw version of this item. The cartridge also consists of separate parts, which are shown in the photo below.
It should be taken into account that if the appointment of a screwdriver is highly specialized, then this may introduce some design changes.
Poperating principle both corded and cordless screwdrivers are the same. It consists in the fact that electrical energy causes the electric motor to rotate. Through the gearbox and the shaft, force and speed are transmitted from the motor to the nozzle fixed in the cartridge. She is already drilling a hole or screwing or unscrewing fasteners. A feature of the process is that the electric motor for network models operates on an alternating voltage of 220 V, and for battery models, on a constant voltage, the value of which can be in the range from 3.5 V to 36 V.
Performing a nozzle change
Changing the nozzle on a screwdriver is not difficult. The tool can be equipped with a keyless or turnkey chuck. Replace the snap in both cases in a similar way. To remove the drill bit from the screwdriver with quick chuck and insert a new or different kind of snap, proceed as follows:
- first, a bit is selected for the size of the cap and the type of slot on it (cross, straight or other) or a drill of the desired diameter corresponding to the material in which the hole is to be created;
- unwind the cartridge counterclockwise;
- in the center, between the divorced cams, the selected type of equipment is installed;
- rotating the cartridge case in the direction of the clock hand, clamp the nozzle.
You can pull the drill out of the screwdriver (or other nozzle) by holding the movable part of the chuck with one hand and pressing the start button with the other. Only first you need to switch the direction of rotation to unwinding.
When the drill driver is equipped with a chuck Full construction, then, to change the equipment, proceed as follows:
- inserting the key into the recess for it, unwind the cartridge;
- I install the nozzle;
- clamp it by turning the key clockwise.
There are models where it is possible to remove one type of chuck, such as a quick release, and replace it with a turnkey equivalent. When choosing any option, it is necessary to focus not only on convenience during work, but it is also worth considering the pros and cons of each of them. So, the turnkey chuck securely clamps the tooling, which is important when drilling, and the keyless chuck allows you to quickly replace it, even with one hand (while the other holds on to the handle, pressing the start button if necessary).
Scope of the screwdriver
To use a screwdriver correctly means to perform with it only those operations that are indicated in operating instructions manufacturer of this product. The main (as intended) for this tool are the following types of work:
- screwing or unscrewing fasteners of various types, including tightening and unscrewing bolts with nuts;
- drilling holes in materials of different hardness.
The use of a screwdriver for its intended purpose is the most common way to use this device, both at home and in construction, furniture production, electrical installation, assembly and car repair. The scope of the product is not limited to these areas: a drill driver is useful wherever you need to work with fasteners (collect and disassemble various structures, equipment, machines) and drill holes of relatively small sizes.
The area of possible application of a particular model is determined by the category it belongs to: household or professional. A tool designed for home use is relatively cheap, has little power and torque. Household models have low performance, as well as limited functionality.
Drill driver made of professional category has extended functionality and high technical performance. Such a tool is designed for continuous, effective use for its intended purpose. It also has much wider possibilities for non-traditional exploitation.
Unconventional use cases
In addition to its direct purpose, an electric screwdriver is used to perform various non-traditional operations. These include the following types of work:
- polishing the car and its headlights;
- mixing small volumes of various building mixtures and paints;
- drilling holes in ice (for this, the tool is equipped with a special nozzle - a drill);
- reinforcement knitting;
- thread cutting;
- mowing the grass cover (for this purpose, they remake the device into a trimmer or lawn mower, or simply insert a nozzle with blades into the cartridge);
- grinding soft grass or thin branches (for this, a garden chopper is created on the basis of a drill-driver);
- surface grinding;
- cutting materials;
- twisting wires.
This is a far from complete list of non-traditional work performed using cordless or corded models of electric screwdrivers. Inventive thought does not stand still. Almost every specialist has options for atypical work for this power tool.
Using a screwdriver, you can restore the car to its original color and shine. To polish the car, use the following types of nozzles:
- leather or fabric circles, with their help, perform the initial cleaning of surfaces;
- felt - they are used for initial processing and finishing polishing (nozzles made of sheepskin are suitable);
- foam.
Together with the equipment, polishing pastes and polishes are also used. They are of the following types:
- silicone;
- abrasive;
- non-abrasive.
With the help of similar tools, headlight polishing is also carried out.
The quality of the result achieved is determined by the right combination of nozzles with polishing agents, as well as the accuracy and skill of the work.
Knitting reinforcing bars using steel wire is very common in the construction industry during the construction of reinforced concrete (monolithic) structures, for example, foundations, houses. Even if you have to do a small amount of work, then working with a hand crochet or pliers is not quite productive. A cordless or corded electric screwdriver equipped with a hook-shaped nozzle will help to knit reinforcement much faster. In this case, the power indicator of the tool is not particularly important.
Twisting stranded wire ends, for example, in junction boxes - this is also a fairly routine job. You can speed up the process with a screwdriver with a special nozzle. How twisting is done is shown in the video below:
Features of drilling concrete, metal, brick with a screwdriver
Electric screwdrivers are used to drill wood, metal, concrete and other materials. At the same time, the functionality of the model used depends on its technical indicators: power, magnitude, torque, the presence of an impact mode of operation, and rotational speed. The instruction manual contains precise instructions on whether it is possible to drill one or another material with a screwdriver. It also lists the maximum diameter of holes that can be created and, in some cases, depth limits.
Brick or concrete wall only a sufficiently powerful drill-driver can drill. In most cases, such devices can operate in shock mode. But drilling a concrete wall with a screwdriver, even an impact type, is quite problematic. This tool is only suitable for one-time operations. This time-consuming work is best done with a hammer drill.
In soft woods even battery products from the household category are capable of creating holes with a cross section of up to 20 mm. With the help of budget models from the ranking of the best electric screwdrivers in 2017, they drill various metals, including steel. In this case, the holes in diameter can reach 10 mm.
For drilling each material, drills of a certain type are used. Nozzles differ not only in the material from which they are made, but also in design, sharpening.
When working with a tool, a rotating drill should enter the surface of the material perpendicular to it - this allows you to evenly distribute the load on the tooling, create more accurate holes.
When drilling metal it is recommended to first make a small depression in the center of the future hole using a core. This will prevent the drill from sliding on smooth metal surfaces. If you need to make a hole of a sufficiently large diameter, then you should pre-drill a smaller one. Also, while working with metal, the nozzle is recommended to be regularly lubricated with a special compound.
When using a drill driver, it should be borne in mind that strong pressure cannot be exerted on it, because this will not only not speed up the work, but can also damage the drill, as well as the power tool itself. Effort must be maintained constantly at the same level. To avoid jamming or breakage of the nozzle, you need to get it out of the drilled hole only when rotating.
