The difference between a screwdriver and a screwdriver drill

What is the difference between a screwdriver and a drill and a hammer drill?

In short, the main difference between a screwdriver and a drill and a hammer drill. torque (which is easily adjustable in a screwdriver, but does not reach the speed of a drill and a hammer drill, as well as does not have an impact force), as well as a fast brake (called a “run-out brake”).

The difference between a drill and a hammer drill

Accordingly, the main difference between a drill and a hammer drill. the impact mechanism of the latter, with which you can hammer the walls in the literal sense of the word 🙂 Heavy hammers are actually called jackhammers. Therefore, the main purpose of the rotary hammer is usually. this is working with bricks and concrete. It is not used for precision drilling in metal and wood.

The difference between a hammer drill and a hammer drill

Manufacturers at some point figured out that punchers for chipping walls, removing irregularities and other serious tasks are needed much less often than just a tool for the appearance of two holes in the wall. And they came up with the idea of ​​releasing impact drills. i.e. hammer drills.

The difference between a hammer drill and a hammer drill is that its main function is still drilling, and if you “abuse” the hammer, the motor or chuck will fail faster. over, its power will be much lower than that of a hammer drill.

The main features of screwdrivers

The screwdriver is good because it weighs a little, comes with batteries (usually two), and easily screws almost everything that needs to be screwed. There are a huge number of companies producing screwdrivers, so their choice is rich.

There are also household and professional screwdrivers. the latter have more powerful motors and batteries, they have more powerful torque.

These are all the main differences. All three tools are designed to punch holes. just

• 1) in different materials,
• 2) at different speeds
• 3) and different scope of work.

Which is better. screwdriver, drill or hammer drill?

The question is which is better. screwdriver, drill or hammer drill. does not make sense 🙂 It all depends on your tasks. To insert wooden windows, a screwdriver is enough. To hide the wiring in a concrete wall, you need a puncher.

Personally, I have a more or less decent screwdriver, which lasts for 3-4 hours, and a simple hammer drill. they are enough for me for most of the work in the apartment and in my thatched-frame house.

Difference between drill and screwdriver

In the modern market for power tools, you can find a wide variety of options that significantly facilitate construction, finishing and other types of work. When it comes to comparing a screwdriver and a drill, many people simply do not see any difference in these devices. Of course, they can be understood: in appearance, both power tools are very similar, even more. they can perform the same function. For example, many craftsmen use a screwdriver as a drill. that is, using a special drill, they make a hole (the main purpose of a drill). However, there is a difference between the two considered devices, and it is significant. In this article, we will focus primarily on the signs of the difference between them.

Definition

A screwdriver is necessary for tightening and unscrewing self-tapping screws and small bolts. The power tool has a built-in mechanism that stops the rotation of the chuck at the moment when the resistance of this rotation reaches its maximum. This is a very important point, because the mechanism prevents damage to the screwdriver attachment. By the way, you should definitely take into account that the above-mentioned mechanism is adjustable. Today, there are two main types of devices: screwdrivers that operate on the mains, and models that operate on a battery. Of course, the price of power tools is different.

A drill is needed to drill holes on various surfaces. It is widely used in construction, decoration, carpentry and assembly work. An interesting fact is that the first electric tool for drilling holes appeared in the middle of the 19th century, and since then it has been constantly improved. The modern drill has two modes of operation: normal and percussion. If in the first case everything is more or less clear. a drill is necessary for drilling ordinary holes in the wall and wood surfaces, then in the second one should be slightly more precise. Impact mode is activated when it is necessary to drill holes in stone or concrete, i.e. in harder surfaces.

Comparison

We have already found out that these power tools perform completely different tasks. But the main differences do not end there:

• The rotational speed of the screwdriver cartridge is significantly lower, plus there is no inertial moment. In other words, as soon as you turn off the screwdriver (release your finger from the button), the chuck immediately stops, while at the drill it spins for some time by inertia.
• Safety precautions. To work with a drill, experts recommend wearing safety glasses so that small particles formed during the drilling process do not get into the eyes. The screwdriver does not need to follow special safety precautions, you just need to be careful and careful when working with the attachment.
• Various operating modes. It was already noted above that the drill can be turned on both normal and percussion mode. Screw gun is regulated only by rotation speed, no more.

Distinctive features

When deciding whether to choose an impact or a shockless model of a screwdriver, first you need to figure out how they differ.

Many consumers who have managed to evaluate the operation of the striking mechanism will say that such a unit is better, and this is how they are ready to substantiate their point of view.

• Directed impacts increase the torque of the impact tool to a range of 80-250 N / m, making it possible to break through the most difficult obstacles. It is significant that in the process there is even no need to firmly press the case against the wall. the tool bites into it even without significant pressing.
• Without the need for constant physical effort applied to the tool, the wrist and hand of the master are much less tired, which allows you to increase the same productivity.
• Considering that even a solid wall is not able to successfully withstand the onslaught of such a tool, it usually does not deform the fasteners, which will allow it to be removed without additional efforts in the future. over, many models also provide for the reverse function of removing old fasteners from the walls, and even the fact that, due to long-term use, it has experienced strong deformation.
• The screwdriver works not only with bolts, but also with nuts, in each case achieving the most tight tightening. A “smart” car usually automatically switches from shockless mode to shock mode when it senses that the nut has become tighter at a certain moment.

Unfortunately, this solution also has certain drawbacks, which may never allow it to completely supplant unstressed models. Thus, an impressive twisting speed is observed only in the shockless mode; when switching to impacts, it significantly decreases.

Chucks for such a tool are not suitable for any. you need strictly hex. Most models do not have a limiting sleeve, so the degree of tightening must be carefully monitored by the operator, otherwise damage to the wall or parts will not be done. Finally, at high speeds, such a unit is capable of producing deafening construction noise, therefore constant work with it requires the mandatory use of protective equipment.

What is it and what is it for?

An impact driver is a special power tool that allows you to most efficiently drill walls in order to drive screws and install other fasteners. Unlike bumpless models, this relative novelty in the domestic market makes a hole not only due to the actual rotation, but also with the help of directional blows. The latter usually do not have a permanent character. the corresponding mode is turned on at the request of the operator or automatically if the drill runs into an obstacle of particular hardness. In a way, it’s a little jackhammer.

Impact screwdriver. the device itself is more complex and “smart”, therefore, a certain versatility should not be surprising. This means that the tool, as a rule, is fully compatible with various attachments, thanks to which the scope of its potential application significantly expands. instead of a drill, you can attach, for example, a hole saw or a mixing attachment.

A distinction should be made between an impact driver and a similar drill. The latter, being focused on making holes, assumes a longitudinal direction of impacts, while a screwdriver strikes as if longitudinally, due to which it significantly increases the torque.

It is logical that such a tool is somewhat more expensive than non-impact models, but its purchase is often justified even at home. the external, load-bearing walls of multi-storey buildings are usually distinguished by the highest strength, which only an impact screwdriver can overcome.

The device is also appreciated by professionals who drill walls or various parts every day. according to them, for all its assertiveness, the drill of an impact driver usually does not cause significant damage to the fasteners, increasing their durability. This characteristic is especially valuable in the context that the same tool is often used to assemble furniture.

The classification of impact screwdrivers is not so extensive, but it can still drive many inexperienced consumers into a dead end. Most of all, the logic in dividing tools into drills, screwdrivers and screwdrivers confuses, but in fact everything is extremely simple here: the mechanism is generally the same for everyone, and the exact name depends on the nozzle.

So, a drill is usually equipped with a drill for making holes, and a screwdriver and a screwdriver at the same time know how to screw in fasteners. Some models imply a simple replacement of nozzles, therefore they can have complex compound names like “screwdriver-drill”, but if such multifunctionality is not provided, the unit is called the most accurate term.

Often, when choosing, beginners are also confused by the fact that the device is supposedly electric and pneumatic. Electric models are the most common, especially at home, but pneumatic ones are perhaps very rare models that will definitely not be in demand at home, the main places of their use are various service stations and tire fitting enterprises.

Since the screwdriver is powered by electricity, it is impossible not to clarify that it can be both mains and battery. The first is good for minor home repairs or daily work in a well-equipped workshop, because it is lighter, and the master does not need to constantly remember to charge the battery.

However, it is the battery version that is the uncontested solution during the construction process or for outdoor use when the working site does not imply the presence of functioning outlets.

Impact screwdrivers: what is it and how is it different from shockless screwdrivers?

• How to choose?
• Operating rules
• Care Tips

One of the original criteria for assessing the masculinity of the owner of the house is considered to be his ability to drive a nail (or, in a modern way, screw a screw) into the wall. Without this elementary skill, it will not be possible to hang a shelf, decorate a room with a picture, or install a curtain rod.

An electric screwdriver is called upon to cope with this task faster and without unnecessary effort, and the impact driver is especially often praised, but not everyone understands what it is and why.

Operating rules

The use of an impact screwdriver will be safe and as effective as possible only if done correctly. Obviously, the first tip is to read the instructions before use, but there are other reasonable tips for use.

The modes of operation, by the way, are described in the instructions for a reason. each of them assumes optimal settings for performing this particular task, and for another it may not be suitable. So, drilling is needed to make holes, and the screwdriver mode is to screw in fasteners, when used, on the contrary, efficiency decreases, but the risk of injury increases.

It is completely unacceptable to change the settings on the fly, with a rotating chuck. this can break the unit.

Always wear protective goggles and gloves, especially with fragile materials. When drilling walls, make sure there are no electrical wires in advance. Remember that the continuous operation of the device is limited. if the nozzle or any other unit is noticeably warm, let it cool.

By the way, if the drilling mode is not provided for in a specific model of a screwdriver, then it is better not to try to drill anything with it. such experiments often end with a burnt out engine.

When using a cordless screwdriver in cold weather, be prepared for the fact that a battery of any type, especially a lithium-ion one, will discharge much faster, therefore you need to charge it more often.

How to choose?

When choosing a specific model of impact screwdriver, pay attention to the smallest details. The first thing that people usually pay attention to is the type of food. Pneumatic models will definitely not be needed at home, but electric models are network and battery, as mentioned above.

The network option is good for working in an equipped room, it is most appreciated for its almost unlimited power. Having given preference to just such a device, evaluate its cable. it must have a considerable length and thickness, have good insulation and not raise doubts about the strength of the place where it enters the unit.

In the case of the battery model, there are more selection criteria. First of all, you need to find a balance between the large battery capacity, which prolongs the battery life, and the weight of the device, because a capacious battery always weighs quite a lot.

Another point is the choice of the type of battery: today the most common lithium-ion models, but nickel-cadmium are also found. The former are good with a small mass with a significant capacity, they allow charging at any time, but they are more expensive than the main competitor and can wear out quickly at low temperatures. The advantages of the nickel-cadmium solution completely eliminate the disadvantages of the lithium-ion version. such a battery is cheaper and not afraid of frost, but it is heavy and environmentally hazardous, and most importantly, it must be completely discharged and then fully charged, otherwise the “memory effect” will provoke rapid wear of the carrier.

Batteries can produce different voltages, but for periodic household work, you can choose models with a value in the range of 12-18 V.

At a high voltage, the engine power also increases, but sky-high rates are not needed for home use: 500-700 W is enough, otherwise the tool will be heavy and unjustifiably expensive.

Screwdriver chucks, in which replaceable nozzles are attached, are quick-clamping and key. The first can be organized in different ways, but its advantage is that it can be serviced with bare hands. The key cartridge has a characteristic rim; a special key is needed to maintain it, which is not always convenient.

Since we are talking about the cartridge, an important criterion is the maximum diameter of its opening. the larger it is, the more different nozzles can be used.

Maximum torque is a measure of how hard the nozzle will rotate. This indicator does not always directly depend on the power of the motor, sometimes it can be increased due to the gearbox, but it is always desirable that the maximum torque be quite high. Models with stepless torque control are in priority, since they are more sparing for fasteners and surfaces that are drilled.

The last, but very important criterion for choosing a tool is its weight. Unfortunately, it is impossible to create a lightweight, and at the same time powerful and multifunctional device, therefore it is necessary to decide which is more important: lightness or performance. Keep in mind that with constant daily work, the first factor may be much more important.

Care Tips

If you purchased a rechargeable model, remember that the battery should always be in the disconnected position, except for direct work. In this case, the nickel-cadmium battery must be completely discharged before turning off the device, and then immediately put on charge. Among other things, it is still not capable of storing a charge for a long time even when it is idle, therefore sometimes it needs to be recharged, even if you have not used it.

A screwdriver gearbox may require periodic lubrication, an indicator that such a moment has already come is a characteristic unpleasant sound and a tight movement of the chuck when trying to rotate it by hand.

In the next video, you will find an overview of the impact and non-impact screwdrivers: AEG BS12CS vs BSB12C2.

Why do you need a screwdriver

Equipping drills with compact rechargeable batteries contributed to the creation of screwdrivers, which opened up new possibilities for carpentry, assembly and other work. They turned out to be especially convenient in confined spaces, when dismantling and assembling wooden and metal structures, installing plasterboard parts.

Outwardly, this tool is not much different from a drill. However, it has been specially designed for quick handling of screw connections, screws and self-tapping screws. There are models that can perform drilling operations. Screwdrivers are designed to provide powerful torque. High rotation speed is contraindicated here. This is provided primarily by a special gearbox that reduces the speed to 200-300 per minute with a simultaneous increase in torque. Such a gearbox is controlled by a special regulator that sets the force required for tightening without deformation of a screw, screw or self-tapping screw.

To counteract jamming, a reversing device with several speeds is installed, as well as an overload warning system. The screwdriver can be equipped with attachments that allow you to loosen and tighten the nuts. Impact screwdriver drives screws or nuts with a series of moderate high-frequency impacts.

A special release clutch controls the tightening force. It also stops the cartridge in case of overload. The use of batteries combined with a screwdriver handle made it extremely popular in construction, assembly production, and in the repair of machines and mechanisms. In the presence of a replaceable power supply, the screwdriver can operate for a long time, which can be increased with the use of the most advanced rechargeable batteries.

What is the difference between a drill and a screwdriver: features and differences

Among hand-held power tools, the drill and screwdriver are among the most common. They dramatically increase efficiency wherever you need to drill holes or handle screw fastening materials. These electrically powered tools can be powered by an ordinary power grid, compact batteries, compressed air and even gasoline. Rotation in them can be combined with percussion functions.

What is a drill

The first drills appeared in ancient times and made it possible to facilitate the work of making holes in stone, wood and other materials. When the electric motor was invented, their capabilities expanded significantly. And with the development of metallurgy and the advent of special drills, they began to make holes in metals and stone with the help of an electric drill. Over time, in addition to production, these tools have become widely used in the household. Their functions were gradually expanded. Special devices were invented that made it possible to grind various surfaces and polish them.

The invention of abrasive cut-off wheels made it possible to use the drill for small-scale cutting work, primarily on pipes and metal rods. Modern drills are characterized by high power, high rotation speed and ergonomics. For them, various options for drills, replaceable chucks, special nozzles and accessories are made to expand the scope of use. For example, using special nozzles, various building mixtures and paints are stirred with a drill. Drills can have normal and percussion modes of operation when you need to drill stone or concrete.

There was a division into a professional tool and one that can be used in everyday life. Professional is distinguished by reliable design and durability, widespread use of rolling bearings. Its parts are made of heat-treated alloy steels. The body is made of high-strength plastic, the lubrication system is closed.

The drills have acquired a convenient housing shape, which houses the electric motor and their control devices. They now have switches, power regulators, impact mechanisms, and other useful devices. It became possible to use drills for tightening and unscrewing screws, screws, self-tapping screws.

feel the difference

The drill and screwdriver are good for performing the functions for which they were created. The drill makes it possible to drill a hole quickly and accurately. Using a screwdriver, self-tapping screws, nuts, screws and screws are also quickly twisted and unscrewed. At the same time, both instruments have certain differences.

• The drill holder in the drill is a keyless chuck, for a round drill in diameter. The screwdriver uses special holders designed for the hex tail of the working bit.
• The drill, even when adjusted, does not provide the correct tightening of the fastener, which can lead to damage to the screw head or the screwing attachment

A special clutch is installed in the screwdriver, which allows you to adjust the force. As a result, the screw or self-tapping screw is twisted to the desired depth.

• Drills for drilling require a torque of 20 Nm and a speed of over 1500 rpm. A screwdriver only needs 10 Nm and 500 rpm for tightening.
• Professional drills in continuous operation run less than comparable screwdrivers, which wear less.
• In an electric drill, it is possible to change the rotation speed. This cannot be done in a screwdriver.
• The electric drill has inertia after it is turned off, which requires increased attention during operation. The screwdriver stops instantly.

What is the difference between a drill and a screwdriver?

Hello everyone! In today’s article I will tell you how a drill differs from a screwdriver, since not everyone understands the difference between them and in the end they do not know what to choose.

To begin with, I propose to define the terms. If we start from the terminology of manufacturers, then screwdrivers they call the device shown in Figure 1. This is a network screwdriver with adjustable rotation speed, reverse, and also having a device thanks to which it is possible to avoid breaking the nozzle slots (bits).

Picture 1

And the manufacturers call drills both the machine shown in Figure 2 and the devices shown in Figure 3 and 4, which are popularly called screwdrivers (mains-powered or battery-powered) or simply screwdrivers.

Picture 2 Picture 3 Picture 4

In order not to get confused, in this article we will assign the following names to each unit:

• the tool from Figure 1 I will call the screwdriver
• from figure 2. drill
• from figures 3 and 4. drill-screwdriver.

At the same time, I note that the difficulties of choosing arise precisely between the last two types, since everything seems to be so clear with a conventional screwdriver. But I’ll describe all three devices early.

Screwdriver

The screwdriver can only be used for tightening self-tapping screws, since it has only a hexagonal seat for the bits. Although it should be said that there are drills with a hexagonal fit, like bits, but usually they are only of small diameters, and they are not everywhere on sale.

Thus, for this tool, we conclude that it can only be purchased for tightening self-tapping screws. At the same time, we remember that it is tied to the network, which means that it will not be possible to work with it autonomously.

It is most convenient to use this unit in any assembly shop, where work is carried out at one working place to screw in self-tapping screws or screws.

Drill

The main function of the drill is drilling. However, if there is an adjustment of revolutions and reverse (and they are now on most models), it can also be used as a screwdriver.

However, they lack any mechanism to automatically prevent bit stripping.

Often, when screwing a self-tapping screw with a drill, its cap can drown unnecessarily in the material, or the slots of the bit scroll in the cap, which can cause them to be ripped off.

Therefore, here you have to rely only on your hands and head.

According to the drill, the verdict will be as follows. Buy it if you are going to mainly drill. But keep in mind that sometimes it can also be used as a screwdriver. in the end, it is in any case more convenient than twisting with a screwdriver.

Drill driver

This tool is versatile. They can be drilled and screwed, without fear of ruining the bit or unnecessarily drowning the hat into the material.

There is a customizable mechanism (popularly referred to as a ratchet) through which the rotation passes. When a certain resistance set by you is reached, it simply turns with a click, and the bit remains in place, safe and sound.

In addition, the drill-screwdriver differs from a conventional electric drill also in that a gearbox is installed on it, which has a large gear ratio. Therefore, with the same engine power, the drill-driver has a greater torque value. This means that, for example, a power drill with a 400 W motor will have the same torque as a 700-800 W drill. However, the dimensions will be smaller.

The price paid for this is the lower number of maximum spindle revolutions. If on drills it reaches a value of 3000 rpm, then on drills their number is no more than 600-800. And if it is two-speed, then all the same, the revolutions will not exceed 1500 per minute.

Thus, we conclude that the drill-screwdriver is a good universal option, since it can perform most of both drilling and screwdriving work.

However, such a tool will not replace a drill in jobs that require high chuck rotation speed. This is, for example, drilling a brick, when the work takes place in percussion mode. And although there is an impact mechanism on some models of screwdrivers, due to the low speed, it is not very effective.

It is also worth remembering that they not only drill with drills, but also, for example, knead mortars using a mixing nozzle. And here, too, high speed is required. Therefore, a drill driver is also poorly suited for such work.

Separately, it should be said about cordless drills and screwdrivers. Firstly, it is drills-screwdrivers that are made with a battery, but there are no classic drills with a rotation speed of up to 3000 rpm with a battery.

Secondly, the use of battery technology has both advantages and disadvantages.

The pluses include the following things:

• autonomy of work. that is, the ability to work for a certain amount of time away from power grids with pre-charged batteries;
• no wires, which is convenient, for example, when working on the roof.

The downsides are the following points:

• aging of batteries. with frequent use, they usually last no more than 3 years, and if used rarely, they still age and in any case become unusable after 5-8 years, even if they just lie idle;
• the inability to immediately start work if it suddenly turned out that the batteries are discharged.

These are my thoughts on the matter. I hope that after reading the article, you understand for yourself which tool you need. Let me finish on this. until we meet again.!

Tool selection by parameters

The first factor that influences when choosing a tool is the purpose and frequency of its use. It is not at all necessary to buy a professional expensive tool if its purpose is to screw something on several times a year. If a cordless drill is necessary for regular use, it is better to look at the professional models with the greatest power and number of functions. Another difference between the usual ones is the operating time of the charger.

In order to choose the right screwdriver, you should pay attention to the possible configuration and parameters of the tool. A drill with a battery can be of different configurations, most often, it is a tool with a large number of attachments. Tools with separate attachments are more convenient to use. Of the parameters by which the selection will be made, the following should be noted:

The difference between a screwdriver and a drill

First, a little help: how does a screwdriver differ from a drill? Many citizens think that if with a battery, then a screwdriver, if with a plug, then a drill. In principle, most screwdrivers do operate on rechargeable batteries, but not all, there are also those that operate on the mains. So this argument is bypassed. And the main difference is that when the button is released, the screwdriver instantly stops rotating, while the drill chuck spins for quite a long time by inertia, simultaneously killing the slots on the screw or even tearing off its (screw) head. The overrun brake is responsible for the instant stop, which is usually not available on a drill.

Also on the body of the screwdriver near the chuck there is a special regulator ring, commonly referred to as a force or power regulator. The correct term is torque regulator. If you have already had a chance to hold a screwdriver in your hands, then you know that if you set this regulator to a minimum, then even just in the GVL you will not be able to tighten the self-tapping screw, the cartridge will stop rotating, and the screwdriver will crackle. This means that the release clutch has worked, and this, in turn, means that the set torque is clearly insufficient for the task at hand and it would be necessary to add by twisting the ring (clutch). The number of steps for adjusting the torque is different for different companies and even for different models, there is no standard in this case. At the same time, most screwdrivers have a set maximum, usually indicated not by a number, but by the image of the drill. Since most screwdrivers have a more complete name sounds like a cordless drill / screwdriver. this means that by switching the clutch to the drill bit, the tool can be used as a drill, the release clutch does not work in this case. True, the coasting brake will work anyway. Well, it is also desirable for common sense to work. if even in your screwdriver you can turn off the release clutch, but according to the passport, the tool is weak, with a torque of no more than 20 Nm, then you should not load a bit on concrete into it and prepare a place for the socket. most likely you just burn the anchor or erase the gears in the planetary gear.

Nevertheless, there are screwdrivers with which you can not only tighten self-tapping screws, but also drill wood, gypsum plasterboard, gypsum plasterboard, and so on using a crown or a feather. as I said, there are many models, everyone can do different things. And in this section we will try to understand them.

Well, let’s start with one of the most popular brands called Makita (Makita), in the recent past Japanese, but now it is clear, mainly Chinese, which, however, in this case is not so scary.

What is the difference between a drill and a screwdriver?

In the modern market for power tools, you can find a wide variety of options that significantly facilitate construction, finishing and other types of work. When it comes to comparing a screwdriver and a drill, many people simply do not see any difference in these devices. Of course, they can be understood: in appearance, both power tools are very similar, even more. they can perform the same function. For example, many craftsmen use a screwdriver as a drill. that is, using a special drill, they make a hole (the main purpose of a drill). However, there is a difference between the two considered devices, and it is significant. In this article, we will focus primarily on the signs of the difference between them.

What is a drill and screwdriver?

A screwdriver is necessary for tightening and unscrewing self-tapping screws and small bolts. The power tool has a built-in mechanism that stops the rotation of the chuck at the moment when the resistance of this rotation reaches its maximum. This is a very important point, because the mechanism prevents damage to the screwdriver attachment. By the way, you should definitely take into account that the above-mentioned mechanism is adjustable. Today, there are two main types of devices: screwdrivers that operate on the mains, and models that operate on a battery. Of course, the price of power tools is different.

Is it worth buying a tool

Sometimes buying a tool may be impractical, for the reason that a screwdriver is simply not suitable for performing certain jobs. Despite the convenience and mobility of drills with batteries, you need to be aware of their disadvantages:

• The weight of the device is quite significant due to the fact that the battery is installed in the body of the tool. It will not be very convenient for working with a canopy.
• In the process of discharging the battery, the power and quality of work decrease. Such a deficiency causes severe discomfort.
• When the battery is discharged, you will have to wait until it is recharged, and if a household screwdriver is used in the work, then this is at least 3-4 hours.
• Over time, the battery loses its power and charge, so sooner or later you will need to purchase a new charger.

We definitely recommend to look

However, if you take into account the peculiarities of the operation of a cordless drill, you can purchase a screwdriver that will fully meet the stated requirements and will work for a long time without being connected to the electrical network. In order to choose a suitable model, the following factors should be remembered:

• Through the autonomous mode, the preparation time of the tool for work depends on the voltage, which ranges from 9 V to 24. This value forms the power on which the weight of the battery itself depends.
• The battery will retain its charge longer if the current-to-time ratio is highest.
• All types of batteries have their own characteristics. Perhaps the best option would be nickel. metal hydride batteries. Although they can withstand fewer charges than lithium, they do not have hazardous substances. However, they are small in size.

For convenience, it is better to choose a model with a separate charging mode. In this case, you do not need to wait for the drill to charge. While one battery is charging, the other will work. Batteries are easy enough to change as needed.

Tool manufacturer

In order to choose a screwdriver, one should not forget that the choice of the tool manufacturer plays an important role. Naturally, a household drill and a professional drill will differ in price and quality, but it is clearly not worth overpaying for a regular screwdriver. You can choose a household screwdriver from Bosch, Hitachi or Hammer.

Most professional drills are manufactured by Dewait. The company’s products are distinguished by a decent value for money. When buying, you should take into account the fact that the cost of the tool, as a rule, doubles, depending on the popularity of the manufacturer. Also, you should pay attention to the list of possible functions. most of them are rarely useful in work, and the price of the tool is greatly increased.

Battery quality

To choose a cordless drill, you need to know the differences between quality batteries. Most often screwdrivers have nickel-metal hydride chargers. They are recognized as environmentally friendly, in contrast to the same cadmium, which contains toxic substances. Toxic batteries are capable of withstanding at least one thousand charges, while environmentally friendly ones. no more than 500. Nickel metal hydride batteries are small in size and practically cannot hold high voltage. They are sensitive to temperature changes. However, if the work is carried out in the cold or heat, this feature does not become a problem.

Another type of battery is lithium. They are much more powerful than nickel ones and have no memory effect. The disadvantage of such batteries is their acute reaction to low temperatures, which is often the cause of tool breakage. Due to this disadvantage, lithium chargers are quite rare.

Before choosing a screwdriver, you need to know about the battery charging speed. Professional models can charge quite quickly, usually 50-60 minutes are enough for this. But household models will have to be charged for 4-6 hours, if there is a memory effect. The more powerful the battery, the faster it charges.
