How To Use A Screwdriver Correctly

How to use a screwdriver drill. Instructions.

Cordless drill / screwdriver. This is a tool that must be present in the working set of any home craftsman. Its versatility allows you to easily perform work both for twisting and unscrewing various types of fasteners (screws, self-tapping screws, screws), as well as drilling holes.

Let’s look at how the drill-driver works and understand the attachments and accessories.

Bits. Nozzles

The screwdriver comes with several types of bits with different shapes of the working edge.

Bits with a straight edge are designed to work with fasteners that have one slot (slot). A suitable bit is selected depending on its length and depth.

Similarly, the shape of the cruciform bit is selected. Here, the width of the slots and the size of the fastener head itself are taken into account. For reliable operation, the edge of the bit must fit tightly into the slots, otherwise there is a possibility licking slots.

To attach the bit to the cartridge, a special attachment with a magnetized holder is used, which prevents the structure from disintegrating and reliably holds the bit in a variety of positions.

To fix the bit with the bat you need to unscrew the movable part of the chuck.

Insert the nozzle and screw in the chuck until it stops.

There are also very convenient double-sided bits, which can be fixed in a chuck without a nozzle.

Setting the torque

The drill has an adjusting ring for setting the torque, on which its values ​​are applied.

This is necessary in order to set the Most suitable value when working with materials with different hardness.

For example, for screwing self-tapping screws into drywall (with little effort), a range of values ​​of 2-4 is suitable, and for hard wood, the torque can be set to the maximum number on the ring.

This adjustment helps to avoid quick damage to the fastener splines.

This allows you to stop the operation of the tool in time when the self-tapping screw or screw is completely tightened.

Battery Charging Procedure

It is necessary to insert the battery into the device observing the polarity (Corresponding signs and. are affixed to both the battery and the device), i.e. Plus is combined with plus, and minus. With a minus.

A glowing red diode on the device panel indicates that the charging process is in progress. This procedure lasts from 3 to 5 hours.

During recharging, the battery and the device may heat up, which is NOT an indicator of a malfunction.

Tool set

Usually, such a tool is sold in a special case, where each part has its own place.

The drill itself consists of a main tool and a removable battery, which is recharged from the household electrical network.

A special charger is used for charging, which comes with the set.

Chuck rotation direction

In the construction of the drill. The screwdriver has a push-type switch with which you can change the direction of rotation of the chuck for tightening or unscrewing the fasteners.

There is a direction mark on either side of the tool next to this switch. Pushed the switch, you can reverse.

It must be remembered that the direction of rotation can be changed only when the electric motor is completely stopped.

The drill chuck can be replaced if necessary. It must be borne in mind that it is fixed with a screw with a left-hand thread and therefore you need to unscrew it clockwise.

This screw can be accessed through the front of the chuck.

The tool kit also includes a set of drills of different diameters. They are all designed to work in soft materials.

The drills are clamped in the chuck in the same way as the bit attachment. (See photo above)

Freezing of the battery is not allowed.

Can a screwdriver drill

If you have a model with two modes of operation. Drilling and screwdriver. Usually professional models have such capabilities, for example Makita DF347DWE. It is not necessary to use a model that does not have a drilling mode, the engine may burn out, since drilling requires higher revolutions to reduce the load.

Is it possible to interfere with the solution with a screwdriver

It is possible, only a special attachment is needed. And of course, neatness, so as not to accidentally fill the screwdriver with a solution.

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 screw the self-tapping screw with a screwdriver safely:

1. Carefully read the instructions before using the instrument for the first time, and not after something unpleasant has happened.

2. Correctly select the maximum torque at which the protective ratchet and the force on the shaft Will not be transmitted. The tool is of course designed for maximum effort. But, firstly, constant work at the maximum reduces the service life. Secondly, the likelihood increases that the screwdriver can pull out of your hands. Thirdly, by learning how to correctly determine the maximum torque, you will reduce the likelihood of damage to the surfaces where you screw the screws. This is especially true for polished and fragile surfaces. For example, in the Bosch GSR 10.8 model, the maximum torque is 30 Nm, but you can also set 5 Nm.

3. Choose the right operating mode. It is not necessary to drill in the screwdriver mode, and even more so to tighten the screws in the drilling mode, where the speed is higher. The tool may simply be snatched from your hands.

4. Do not forget to control the direction of rotation. We tighten the screw. The cartridge should rotate clockwise, unscrew it. Against.

5. Without changing any cutting mode settings on the fly! This threatens to break the screwdriver and is unsafe.

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

  • Work only with safety goggles and preferably with protective gloves, especially if you are drilling materials that can crack and shoot sharp shards.
  • Before drilling Make sure there are electrical cables and other utility lines in the area.
  • When tightening and loosening screws, as well as drilling small holes in diameter, DO NOT lean on the screwdriver. The screw or drill bit may break and injure you.
  • Household and professional screwdriver models have different continuous operation times. In any case, it is! And proves the tool to a hot state is not worth it.
  • After work, you need to disconnect the battery, remove the attachment, wipe the tool from dust.

Do I need to lubricate the screwdriver

This tool has a gearbox and requires lubrication, such as ELF MULTI MOS. The frequency depends on the model and the intensity of use. The following signs indicate that your tool needs lubrication:

  • Unpleasant hysterical sound;
  • It is difficult to rotate the cartridge by hand.

You can lubricate with lithol, Manolo, silicone or Teflon grease.

Is it possible to cut a thread with a screwdriver

It is possible, but with reservations. Firstly, small diameters, up to 10 mm. Pipe thread ¾ in. you don’t exactly slice. Secondly, only internal. You will NOT install the die on the screwdriver. Third, skill is required. A slight misalignment and that’s it, either I’ll break the taps, or just ruin the thread. Minimal cutting effort!

Charging the screwdriver

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

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

How much you need to charge the battery depends on its type and capacity. Li-Ion batteries gain charge most quickly. The battery of a household screwdriver takes an hour to charge. The same capacity Ni-Cd battery will be charged for 7 hours.

How do you know if a screwdriver is loaded? The charger has an indicator, for example, in the DeWalt 572576-01 model, it is the case. The red light is on. Battery charging, green. Can be used. You can also focus on your own experience. By the charging time and the nature of the screwdriver’s work, you can judge the charging of its battery.

If you have a model with a nickel-cadmium battery, then you should know how to swing a screwdriver battery, which will inevitably decrease its capacity after several years of use. And if you use the tool incorrectly, that is, does not bring the battery to full discharge before charging, then faster.

In order to restore capacity, you need to know how to discharge a screwdriver battery correctly. And this means a smooth decrease in the charge, by connecting a twelve-volt light bulb with a power of 25.40 watts to it. After a complete discharge, it charges the battery to capacity and then discharges it again. Repeat the procedure at least 5 times. It is NOT possible to fully restore the capacity by such a procedure, but significantly increase the operating time of the screwdriver completely.

Tool selection

The most important indicators to look out for when buying. Rotation speed and power of the screwdriver.

The rotation speed affects the functionality of the device. For tightening or unscrewing fasteners, tools whose speed does NOT exceed 350 rpm. For drilling, you will need devices whose rotation speed is greater than or equal to 1000 revolutions.

If you plan to purchase a cordless screwdriver, you should find out its type. The most common devices with lithium-ion cells are characterized by 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 element is more suitable. They are cheaper and not as prone to self-discharge as lithium-ion. Mains powered devices are also suitable for purely home use.

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

  • Illumination of the working area;
  • Torque boost pulse, used to drown fastener heads;
  • Impact mechanism;
  • Increasing rotation speed.

Screwing and tightening fasteners

Instructions for using the device are simple:

  • Insert the tip of the nozzle into the slot of the screw or screw, turn on the device.
  • To increase or decrease the tightening speed, increase or decrease the pressure on the start button.
  • When the self-tapping screw is tightened, the force limiting mechanism will automatically work, after which the work will stop.
  • To unscrew the screw, the nozzle is placed in the slot, pre-installed the lever of the direction of rotation of the nozzle in the opposite direction.

Types of screwdriver

Modern devices are divided into subspecies, which differ in functionality.

  • Screwdrivers, with which you can only tighten fasteners;
  • Wrenches used to tighten hexagons;
  • Cordless screwdrivers. Least powerful basic tools;
  • Drill drivers also used for drilling holes.

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

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

Features of operation

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

It is also necessary to correctly select the torque of the device, taking the hardness of the material with which they work:

  • Fiberboard and drywall. To screw the screws into these materials, use 1-4 modes.
  • 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 slot will be damaged.

You can use a screwdriver as a drill only for a short time. With prolonged use of the tool, which is NOT intended for drilling, the electric motor may overheat, which will lead to damage to the device.

How to use a screwdriver: instructions for beginners

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


The tool consists of a housing containing a motor and a gear mechanism; chuck (clip for replaceable drills) battery or cord for connecting the device to the network.

How to attach a bit or drill

There are two ways to fix a drill or bit in a screwdriver. The first method is manual. The bit is inserted into the chuck and tightened by hand. Second way. This is tightening the bit or drill with a rotating chuck, support it with your other hand. It is very easy to check how you secured the bat. Try to screw one self-tapping screw, and you will understand whether the bit is scrolling or not.

Drilling mode

If you decide to use the Screwdriver as a drill for the purpose of drilling a hole in wood or plastic, then in order for the hole to be of high quality, you need to put an even piece of wood under the objects that are drills. This way you can avoid cracks and chips when drilling.

Drilling a hole in metal involves following some rules. The place of the future hole must be screwed. This will help prevent the drill from sliding over 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 down hard on the Screwdriver while drilling. If the drill is stuck, then Unscrewing it will help switching the Screwdriver to unscrewing mode. If you are drilling a small part, then in order to hold it, use pressure.

How to use a screwdriver: Step by step instructions

Each person at least once in his life made repairs at his home or performed work related to the repair of his apartment or summer cottage. Today, the screwdriver is an indispensable repair assistant. When buying it, be sure to find out the power, equipment, as well as the warranty period for this power tool.

How to use the battery Screwdriver

Before you start Make sure that the battery of your Screwdriver is fully charged. Insert it into the charger and pay attention to the indicator. A green light indicates that the battery is charged. The red light 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 overall battery life. Also, the temperature of the room in which the Screwdriver is operating is too hot or too cold has a detrimental effect on the battery life. One battery lasts five hours.

Safety engineering

Before using the Screwdriver, be sure to read about the safety precautions in the memo attached to the tool. This tool is often used in production. Typically the instruction “how to use a screwdriver” must be mandatory in labor protection acts. In order to prevent accidents, when working with the Screwdriver, you must follow all safety rules. Do not trust the tool to people who do not know how to use a screwdriver and cannot follow safety precautions. For example, children, elderly, sick people and people in a state of AL-KO intoxication.

Please wear protective clothing and glasses before using this tool. Remember that any tool, whatever it may be, is source of danger.

Application Screwdriver

Do not think that the Screwdriver can be used only to drill, twist and unscrew the screws. We repair a car, you can unscrew and tighten nuts and bolts, grinding with various surface attachments. Assembling furniture without using a screwdriver will take a lot of time. Hanging curtain rails or bookshelves with a screwdriver is much easier than running around with a screwdriver and applying force. So today the Screwdriver has taken its place of honor among the most essential tools in the household.

Varieties of screwdrivers

In today’s market of tools, a large number of various screwdrivers are presented, here is a catalog of popular models of well-known brands. Each type of screwdriver has a different function and purpose. Let’s highlight the main types:

  • Drill screwdriver;
  • Wrench;
  • Cordless screwdriver;
  • Classic screwdriver.

The similarity of all types is that in essence they all perform the same task.

A drill driver, in fact, is an ordinary screwdriver with the ability to drill at high speeds (over 3000 rpm). A classic screwdriver, as a rule, turns at a speed of no more than 1200 rpm. The main task of the wrench. This is to tighten the nuts and bolts. Finally, the cordless screwdriver is designed for loosening / tightening fasteners with a Phillips or Hex head. Generally, cordless screwdrivers are lightweight but also have the lowest power.

The classic screwdriver The most common tool on the farm. If you are making a drywall structure or making a bath in the country, then the screwdriver will be your indispensable assistant. Having worked with such a tool at least once, you understand that it is simply irreplaceable in everyday life.

How to use a screwdriver?

Often a household needs a tool that will allow you to quickly tighten or unscrew the fasteners. Of course, you can also use a regular screwdriver. But what if you need to tighten about 200 screws? Then such a wonderful tool as a screwdriver comes to our aid.

Despite the fact that the device of the screwdriver is quite simple, there are still many people who do not fully understand how to use it correctly. In this article, we will try to fill the gap in how to use a screwdriver correctly.

What you should pay attention to when choosing a screwdriver?

There are several parameters to be guided by when choosing a screwdriver.

The very first. This is food. Screwdrivers are battery-powered and networked. If you plan to use a screwdriver in the country or other places where electricity is not always available, then it is better to take a cordless screwdriver. I would also like to say that the type of battery is very important in cordless screwdrivers. If the battery is Li-ion. These batteries discharge very quickly in the cold, but they are more reliable and durable. For low temperatures, Ni-cad batteries are better suited. But they require more careful maintenance.

The next important parameter. Power of the screwdriver. The power of a screwdriver can be expressed in its torque. The more torque, the longer the screw you can screw in. Typically, 30Nm torque is sufficient for domestic use.

Rotational speed. If you plan to use a screwdriver as a drill, then it is necessary that the number of revolutions is not less than 1000 rpm. However, if drilling work is not planned, then you can limit yourself to 300 revolutions.

Drill / bit clamping mechanism. Basically, screwdrivers with a keyless chuck now prevail. This allows you to quickly change attachments during operation. But still there is also a key patron. In a screwdriver with a key chuck. The drill is clamped much more reliably, but changing drills / bits in such a screwdriver will not work quickly.

Also in modern screwdrivers, there are functions such as:

  • Highlighting the work area;
  • Impact drill mode (very handy function if you plan to work with concrete).

Getting started with a screwdriver

First you need to fix the nozzle in the screwdriver chuck. If you have a screwdriver with a keyless chuck, then simply insert the bit into it and tighten it by turning the chuck clockwise (on some models and counterclockwise). If a screwdriver with a key chuck, then using the wrench that comes with the kit, you will need to fix the drill.

Next, you need to select the rotation speed. The rotational speed of the screwdriver is set by a special switch located on the body. If you plan to tighten / unscrew fasteners or nuts, then low speed is also suitable for such work (and the tool will last much longer). For drilling work, high speed is required, but here it is also worth understanding what material you are going to drill.

Finally, you can adjust the torque of the screwdriver. This can be done using the regulator on the cartridge itself. If you set a high torque, then when screwing in the screws, you can rip off the screw cap or even break the screw itself. Therefore, set the torque at which the efficiency of the tool will be the highest.

Security measures

Try NOT to use a screwdriver as a drill. If so really needed, then it should be short-term work. Otherwise, you will have to carry the screwdriver for repairs or in the trash very soon.

Change the torque or direction of the bit while the tool is running. This action is strictly prohibited. This will cause immediate damage. Do not allow moisture and dust to enter the internal mechanisms.

If you have a cordless screwdriver at your disposal, the batteries are periodically charged. Especially if these are ni-cad batteries (once a month). Li-ion batteries are a little easier. They can be charged much less frequently.

The screwdriver is a fairly simple tool to use. But you should still be careful when working with him.

Tips on how to use a screwdriver correctly

Screwdriver. A tool designed to tighten fasteners. If you have drills and special attachments, it can also be used to perform some other operations.

  • Device and purpose
  • How to work in twist mode?
  • Can I drill?
  • Polishing
  • Operating tips
  • Instrument care instructions


To polish the body, headlights of a car or other surface using a screwdriver, you need additional attachments. Polishing wheels. Circles made of cord or leather are used for preliminary cleaning. Felt attachments are used for both cleaning and final polishing.

  • The surface to be polished is washed from dirt and dust;
  • Dry;
  • Apply an abrasive compound to the polishing wheel;
  • Sequentially treat all areas with smooth movements without strong pressure.

In the process, the circle is periodically cleaned of paste residues with a clean rag. Polishing Takes a long time, the battery may be discharged. If the device becomes very hot, you need to turn it off and wait a while before resuming operation.

Operating tips

To work effectively with a screwdriver, you need to set the correct torque. When working with soft materials (drywall), switch it to the minimum mode, when drilling or screwing fasteners into hard surfaces. To the maximum. Before changing the mode, you need to turn off the device and wait until the engine stops completely.

To prevent dust from flying into your eyes when drilling into the ceiling, you can put a plastic or paper cup on the drill. All dirt will collect in it, and it will be easier to control the progress of work.

How to work in twist mode?

Before starting work, you need to prepare the tool. If it is running on battery power, you need to put it on charge.

How To Use A Screwdriver Correctly

Next step. Setting the bit. To choose the right nozzle, you need to take into account the size of the fastener head and the type of slots. Bits differ in type and diameter:

  • Slotted. Most commonly used. Designed for tightening countersunk screws with a flat head screwdriver, screws. Tip width varies.
  • Cross. With their help, self-tapping screws, countersunk head screws are twisted and unscrewed. The tip has 4 radial diagonal ribs.
  • Hexagonal. It is used for fasteners, the head of which has hexagonal recesses. Screws and screws of this type are used in the assembly of furniture and appliances.
  • For bolts and nuts. A nozzle with a tip with a hexagonal recess inside. With her, the tool is used as a wrench, screws, screws, bolts are tightened.

There are other attachments, but they are used less often. How to change or even remove a bat? Having determined which bit is needed, insert it into the cartridge. The installation method depends on the type of cartridge. Insert the quick-release bit as follows: turn the chuck counterclockwise until the distance between the cams does NOT increase. Push the end of the nozzle between them, turn the cartridge clockwise so that the cams close and securely fix the part.

In a screwdriver, equipping with a turnkey chuck, the process of changing the nozzle is more complicated. First, a key is inserted into a special hole on the device, rotated counterclockwise to loosen the clamp. Insert the bat, fix it by turning the key clockwise.

Next step. Checking the performance of the tool. If the screwdriver is powered from the mains, connect it to an outlet. Press the start button, check if the bit scrolls. The rotation speed is adjusted using the same button, weakening or increasing the pressure. Insert the tip of the bit into the recess on the head of the fastener, press the start button.

If you need to unscrew the self-tapping screw or screw, switch the reverse button.

Device and purpose

The screwdriver is used for various construction and repair work, but its main function. Quick screwing in and out of fasteners: self-tapping screws, screws, bolts, screws.

It helps you tackle a large volume of tasks in significantly less time than using a screwdriver.

Low- and medium-power budget screwdrivers are used in the assembly, installation and dismantling of furniture, equipment, the construction of frame structures (partitions, walls, suspended ceilings) and other objects. Powerful hammering tool handles hole drilling.

In addition to the standard operations listed in the instructions for the screwdriver, it can be used for other tasks. With the help of a mixer attachment, they Mix light solutions. Through a special adapter, connect the device to an ice screw to quickly make holes.

Most screwdrivers are made of plastic. This reduces the overall weight of the tool. Inside the case are located:

  • Engine. Depending on the type of device, it can be electric or pneumatic. The former are powered by a network or battery, the latter. From a compressed air tank or compressor.
  • Reducer. Gear mechanism, which transmits rotational movements from the motor to the spindle.
  • Regulator clutch. Connections with a gearbox, with its help, the screwing depth and torque are adjusted.
  • Starting capacitor. He starts the engine.
  • Chuck. Bits, drills, socket heads are inserted into it. The most common quick-clamping three- or four-jaw.
  • Power supply (battery) and / or power cord.

On the case there is a control panel with a power button, a speed switch. To work in the unscrewing mode, use the reverse. Additionally, the screwdriver can be illuminated, a fuse.

Can I drill?

It is possible to use a tool instead of a drill only if such a possibility is indicated in the technical passport of the device.

However, soft materials such as drywall can be drilled even with a low-power screwdriver.

To do this, instead of a bit, you need to insert a drill into the chuck to work with gypsum board.

To remove the drill or other bits, you need to unscrew the chuck by hand or wrench. You also need to move the sleeve to the appropriate position, usually this mode shows the drill icon. The attachment is placed at right angles to the marked surface. It is not recommended to deviate. This will complicate the drill stroke, increase the diameter of the hole to be made.

To drill a concrete or brick wall, tiles, you will need a tool with a high rotation speed (from 1200 rpm) and a large torque. Impact screwdrivers do the job more efficiently and faster.
