How to use a drill and screwdriver. How to use a screwdriver. So that the screwdriver serves for a long time. Tool usage options

The presented tool can be mains-powered or cordless, and according to the type of work, there are drill-drivers, cordless screwdrivers, impact wrenches and screwdrivers. All these tools have the same operating principle, but perform different functions.

If a conventional screwdriver only works with fasteners, then a drill-driver can also drill holes. The impact wrench is designed for loosening or tightening bolts and nuts. The cordless screwdriver has a Phillips-shaped bit. In terms of power, this device is weak.

Working without the presented tool is quite difficult, especially if you have to tighten a large number of screws. Arrangement suspended ceiling, attaching insulation or drywall to the surface and many other actions - that’s what a screwdriver is for.

How to use a screwdriver - setup stage

The design of the screwdriver is quite simple. The plastic housing houses the motor and gears that drive the bit. The bit is located at the end of the device. Also present on the body LED backlight, speed and direction switches, torque regulator, power switch.

Principle of operation The screwdriver is also very simple. With the help of an engine, a shaft with a cartridge is driven through a gearbox, in which the necessary attachment is fixed. Now that you know how a screwdriver works, you can learn how to use it. First you need to provide safe conditions work. It is also advisable to check whether the battery is well charged. If everything is in order, then you can start working.

Before using a screwdriver, you need to insert the desired attachment into it. It is selected in accordance with the size of the head of the self-tapping screw or screw. To do this, you need to remove the chuck and coupling from the device and insert the bit into magnetic holder, which is then reinserted into the device and fixed in it.

Now you can adjust the bit rotation speed. For this purpose, the device has a special regulator. It is advisable to carry out this stage before you start using the tool. To know how to operate a screwdriver correctly, you must first understand changing the direction of rotation of the spindle, for which there is also a switch.

Using the chuck, the depth of the self-tapping screw is adjusted. The magnetic holder will need to be replaced from time to time. To do this, you need to remove it by first removing the chuck with coupling from the screwdriver, replacing it with a different type of holder of a different type and again installing all the elements in their place.

How to use a screwdriver - accuracy and safety

After the settings are made, you can start using the tool. To do this, the battery is connected to the device and necessary work. Knowing how to use a screwdriver correctly, you can avoid unwanted actions when handling the device, which will increase its trouble-free service life.

You cannot adjust the frequency and direction of rotation of the nozzle if the device is turned on and running. The device should be protected from moisture getting inside it. The room in which the device will be used must be well lit, and the electrical power supply must be stable, without fluctuations.

Do not touch the device to grounded objects, otherwise the user may receive an electric shock. Do not use the device continuously for a long time, otherwise it will simply burn out. It is advisable to work only with a working device and in special protective clothing.

Screwdrivers are used by home craftsmen, in addition to their direct purpose (screwing in screws, self-tapping screws and other fasteners, drilling various holes) in quite unusual cases. For example, you can use a screwdriver to clean clogged drains and sewer pipes. For this purpose in chuck you need to secure a wire bent in half or a small cable for cleaning sewer pipes, carefully insert it into the drain hole and clean the clogged pipe at low speeds.

A screwdriver will also help you wind it up compactly for storage. large segments ropes, wires or wires. Using a screw-in screw, attach it to the cartridge wooden block, onto which a wire or something else will be wound at low speeds. Using the same principle, you can twist the wire when making a spring at home.

By attaching a brush to the cartridge, you can quickly polish your shoes until they shine)

If you don’t have a screwdriver yet, you can buy an inexpensive model, for example something from the Zenit brand, on the website http://ek.ua/list/344/zenit/.E-Katalog will help you choose equipment with the specified parameters at the best price.

Cordless screwdriver can be useful when cleaning bathrooms and plumbing fixtures.

This device will make your manual labor much easier.

But real "Mom's engineer" manifests itself if a man is allowed into the kitchen! Here laziness and engineering imagination get a huge scope for creativity)))

The most common use of a screwdriver in the kitchen is to use it as a mixer. After all, it’s enough to secure a whisk, fork or even scissors in the chuck and you can easily whip cream or knead dough.

It's also quite unusual to use a screwdriver as a blender.

Craftsmen also adapt a screwdriver to a manual one. coffee grinder, pepper grinder and even a meat grinder. And when cleaning large quantity potatoes or apples, this gadget generally becomes indispensable!

If you have rubber boat, but there is no motor, then you can build a portable electric motor from cordless screwdriver. Charging one battery will last for 7-10 minutes)

Electric motor for boat

A cordless drill-driver is a tool that must be present in the work kit of any home handyman. Its versatility allows you to easily perform both screwing and unscrewing work. various types fasteners (screws, self-tapping screws, screws), as well as drilling holes.

Let's look at how a drill/driver works and understand the attachments and accessories.

Tool kit

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

The drill/driver itself consists of a main tool and a removable battery, which is recharged from a household electrical outlet.

For charging, a special charger is used that comes with the set.

Battery charging procedure

It is necessary to insert the battery into the device, observing the polarity (the corresponding “+” and “-” signs are placed on both the battery and the device), i.e. a plus is combined with a plus, and a minus is combined 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.

The rechargeable battery is protected from overcharging, so it can be left in the device for a longer period of time, but not more than 24 hours.

During charging, the battery and the device itself may become warm, but this does not indicate a malfunction.

Bits - attachments

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

Straight edge bits are designed to work with fasteners that have a single slot (spline). Depending on its length and depth, a suitable bit is selected.

The shape of the cross-shaped bit is selected in the same way - the width of the slot and the dimensions of the fastener head itself are taken into account here. For reliable operation, the edge of the bit must fit tightly into the splines, otherwise there is a risk of “licking off” the edges of the splines.

To attach the bat to the chuck, a special attachment with a magnetized holder is used, which prevents the structure from falling apart and reliably holds the bat in a variety of positions.

To secure the bit attachment, you need to unscrew the moving part of the chuck.

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

There are also very convenient double-sided bits that can be fixed in a chuck without an attachment.

Torque setting

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

This is necessary in order to set the most suitable value when working with materials of varying hardness.

For example, for screwing self-tapping screws into drywall (with little force), a value range 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 rapid damage to the fastener splines.

During operation, you can change the speed of rotation, increasing or decreasing the pressure on the trigger of the tool.

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

Chuck rotation direction

The design of the drill-screwdriver has a push-type switch with which you can change the direction of rotation of the chuck to tighten or unscrew the fastener.

There is a directional designation on both sides of the instrument near this switch. By pressing the switch, you can reverse.

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

In the middle position, the switch blocks the operation of the tool. This locking is used while replacing bits or drills.

If necessary, the drill-driver chuck can be replaced. It must be borne in mind that it is fixed with a screw with a left-hand thread, which means it must be unscrewed clockwise.

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

The tool kit also includes a set of drills of different diameters. All of them are designed to work in relatively soft materials.

The drill bits are clamped in the chuck in the same way as a bit attachment (see photo above)

To care for the instrument, simply wipe its body with a damp cloth and then dry it; do not use household chemicals and solvents.

Freezing is not allowed battery.

Before starting work, you should make sure that all parts of the tool are in good condition;

After a long break in operation, the battery still discharges; in this case, it should be recharged;

It is necessary to make sure that there is no electrical cable passing through the drilling areas and no water or gas pipes are buried;

When operating the tool, it is necessary to avoid frequent braking of the electric motor, this can damage the battery;

Be careful to check the polarity when connecting to the charger;

The first battery charge can last up to 12 hours;

Avoid getting moisture on the instrument body;

A screwdriver often replaces a regular screwdriver. Many models are equipped with a drilling function. In each case, you need to select the equipment correctly and use it correctly so as not to damage the tool and fasteners.

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.

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:

• splined. They differ in the width and thickness of the slot;
• crusades. They have different angles at the base and shapes;
• hexagonal. The main characteristic of the bit is the distance between the sides of the hexagon;
• tetrahedral;
• asterisks. This shape improves adhesion between the nozzle and the fastener.

Types of special bits:

• tri wing or triangular;
• double pin. Similar to spline ones, but with a notch in the middle;
• torq set. Like trihedral, but with four rays;
• end Usually performed with a magnet;
• for drywall. They have a persistent limiter;
• with spring lock.

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

Example of a combination nozzle

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.

• quick-release chuck. There are single-coupling and double-coupling types. Installed most often. To open the jaws and remove the old bit, rotate the front clutch counterclockwise. Insert a new bit and screw the coupling back on;
• hexagonal chuck with magnet. The nozzle is simply inserted and pulled out;
• snap clamp. Found in pneumatic screwdrivers. The nozzle is inserted and snapped into place. To remove it, you need to pull the bit while holding the head of the clamp.

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, gas-burner or gas stove, a small container for oil from any tin can, a piece of steel wire.

1. Wrap the wire around the bat so that it does not fall out.
2. Pour oil into a container. Light the gas in the burner and heat the bat until red hot. The main thing is not to overcook it.
3. Place the red attachment in the oil for 5-6 seconds. Remove for 2-3 seconds. Do this several times.

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 special device for magnetizing and demagnetizing screwdrivers. 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.

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. In too soft material The head of the fastener is easily recessed and can pass 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.

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.

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:

1. In a double-clutch quick-release chuck, hold the rear clutch and turn the front clutch counterclockwise.
2. If there is only one clutch, then turn it.
3. The fists will unclench. Insert the drill bit.
4. Turn the clutch counterclockwise to clamp the drill bit into the jaws.
5. There are three holes in the key chuck. Insert the key into them one by one and turn until they rotate freely. The teeth of the wrench must engage the teeth of the chuck.
6. Rotate the chuck counterclockwise until the jaws move apart. Remove the old drill bit and insert the new one.
7. First screw in the cartridge. Then use a wrench to tighten each hole.

Other uses

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

• Polish;
• chamfer the bolts;
• work at any angle and in hard-to-reach places;
• sharpen knives;
• Safely and quickly tighten screws using one hand. For this purpose, a nozzle with a tape magazine of self-tapping screws is provided;
• install rivets;
• cut corrugated sheets with turbo shears;
• light the fire with a hairdryer attachment.

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.

Contrary to popular belief, not every man knows how to use a screwdriver. What can we say about women?

Such knowledge can hardly be called innate, so it is better to learn the intricacies of the work in advance if you do not want to harm your own health or the mechanism of the device.

There are several basic rules for working with a screwdriver. How you work depends on the type of device you are using. If you managed to buy a screwdriver or receive it as a gift, find out in advance how to use such a device correctly.

Let's start with the basics. There are several classifications of devices of this type that you can use in your work.

What types of screwdrivers are there?

Let's start with the classification by type of nutrition. Highlight:

• battery,
• network devices.

The former can work in any conditions, regardless of whether they are connected to the network or not. The battery is charged from the mains and holds a charge for a certain time, depending on its capacity.

Corded screwdrivers only work when they are connected to the network. This is not always convenient, and does not allow you to move far enough away from the outlet. However, when working with such a screwdriver, you don’t have to worry about the battery running out at the most inopportune moment.

By type of operation, several groups of devices can also be distinguished:

• Cordless screwdriver - not very powerful, has a Phillips-shaped bit.
• Impact wrench - designed for tightening and unscrewing nuts.
• A drill-driver not only tightens and unscrews screws, but can also make holes, having a variety of drills in its arsenal.
• A screwdriver is the most common version, used most often for loosening and tightening screws.

The speed of work depends on its complexity, the power of the device you are working with, and the properties of the materials. In short, there are many factors that influence the operation, but the principle of operation of all screwdrivers is approximately the same.

How does a screwdriver work?

The bit, which is the main operating element, is driven by a small motor and gears located inside the screwdriver body. Depending on the configuration, the screwdriver may also have additional lighting, speed switches, etc.

A certain attachment is fixed into the cartridge, then, when the toggle switch is switched, the shaft with the cartridge is driven by the switched on engine. The rotation speed depends on which mode you select. In any case, touching the drill while the screwdriver is on is quite dangerous.

It is important to provide yourself with safe working conditions. Also, make sure the screwdriver is sufficiently charged before starting work.

Working with a screwdriver

So, when starting work, you must choose the right nozzle. This is quite simple to do - you need to take the attachment that corresponds to the size of the screw head or self-tapping screw.

It is necessary to remove the cartridge and coupling from the device, insert the bit into the magnetic holder, and install the remaining elements in place. Make sure that the bit in the screwdriver is installed securely enough.

Another stage of preparation for work is adjusting the bit rotation speed. Using a special regulator, you should test in advance, without starting work, how fast the bit rotates.

Also, by switching the regulator, determine in which direction it rotates to tighten the screw, and in which direction it should rotate when it is necessary to remove the screw from the material.

In addition, it is necessary to check the depth to which the screw will enter the material. From time to time, to adjust the depth of penetration, it will be necessary to change the magnetic holder.

After the settings are made, you can start working.

If you know how to properly use a screwdriver and have made the correct settings, you can be sure that your device will last as long as possible. An important role in determining the service life of a screwdriver is played by its original quality.

At http://www.ru.all.biz/ you will find a large selection of devices that will become excellent helpers in your household for many years. At the same time, the cost of screwdrivers will not be too high.

Please note that the device cannot be adjusted while the screwdriver is running or connected to the network. This can be dangerous, first of all, for you.

Prevent water from getting inside the device and the device falling from a great height. In addition, if the screwdriver is powered by the network, you need to make sure that the network is stable and without fluctuations.

Do not touch grounded objects while the screwdriver is running to avoid electric shock. Remember that a certain amount of caution should always be present when working with electrical items.
