How to choose an electric corded screwdriver: which one is better. Corded screwdriver Corded or corded drill screwdriver

Screwdrivers have firmly entered our lives and are increasingly replacing the classic screwdriver when carrying out repairs and finishing works. The choice of this tool is so diverse that it often makes you think about which model is best to choose for use.

Before making a choice in favor of one or another option and answering the question “Which cordless screwdriver is better?”, You should clearly understand for what purpose the tool is purchased: for home use or to solve various professional problems.

On sale you can find household, semi-professional and professional screwdrivers.

A household screwdriver is characterized by:

relatively low cost;
low productivity;
low power;
simple assembly;
cheap components;
small capacity battery.

Professional and semi-professional devices are:

high build quality;
powerful engine that can withstand constant loads;
excellent battery life;
ergonomic design;
optimal cost, fully consistent with quality;
reliability in operation;
shockproof housing.

The basis of the power tools market is occupied by cordless screwdrivers, which are displacing models powered by electricity every year. Autonomous power supply allows you to perform wide range tasks. This is especially true for those who do not have the opportunity or simply do not like to constantly carry an extension cord with them and every time look for an outlet to connect the device.

A few words about famous brands

If you really want to buy quality tool, which would serve for more than one year without failures in operation, without necessary repairs and updates, then it is best to purchase a model from a well-known world brand; there are never any complaints about the quality, assembly, reliability and service life.

Bosh - time-tested quality

The Bosh cordless screwdriver, which belongs to the line of professional models, has proven itself to be excellent, characterized by high performance, impact-resistant casing, impeccable assembly and reliable operation. The company, whose products are successfully sold in more than a hundred countries around the world, has been specializing in the production of professional power tools for several decades. When choosing Bosh, you choose quality!

Makita cordless screwdriver - a Japanese tool with an 80-year history of existence

In the same price segment and with similar technical and operational characteristics there is also a Makita screwdriver, the manufacturers of which pay special attention such indicators as:

production resource;
high build quality;
ergonomic design;
high power;
versatility of application.

Five main advantages of battery models

high level of security. There should be no doubt about this “plus” - since contact with high voltage is completely excluded, and, as a consequence, the impossibility of electric shock during operation;
mobility. The self-powered tool can be used anywhere, anyhow. This is especially true for work in rooms with no electricity.
durability. The cordless screwdriver features high performance and a long battery life. Models from well-known brands are guaranteed to last for more than five years even with high intensity of use;
reliability in operation. For many, battery-powered devices are a godsend in operating conditions. summer cottage or in the garage. One fully charged battery will be enough for intensive use for 3-4 hours, and in some cases more;
high labor productivity.

When is it better to choose network-powered models?

When constantly working with hard materials, for example in a carpentry workshop or country house When continuous operation of a power tool is required, you should still consider purchasing a screwdriver that runs on household power. The user does not have to think about where and how to recharge the tool, and such models cost an order of magnitude less than their battery-powered “brothers.”

In addition, such models are distinguished by high power and productivity, which allows you to screw in even long screws and drill holes of any depth without much difficulty. Operating from a constant source of electricity will allow you to operate the tool continuously.

Say no to cheap power tools

The more famous the brand, the more expensive the product. This pattern, alas, has not been canceled. Everyone knows about such power tool manufacturers as, for example, Bosh and Makita. Cordless screwdrivers of these brands will not only differ in price from products of lesser-known brands, but also in quality, to which there should be no complaints at all. These companies produce truly high-quality, reliable, high-performance tools, which most often fall into the category of semi-professional or professional.

Of course, when choosing a product, there is often a tangible temptation to purchase a cheaper option from a less well-known company. But here it is important to clearly understand that, in essence, you are buying a “pig in a poke.” Sometimes this is justified, since today you can find a screwdriver with quite good technical characteristics from a manufacturer whose name has not yet been heard. But at the same time, I would like to warn you that you should not give preference to a tool that is too cheap. Why?

The fact is that often the characteristics of a screwdriver declared by the manufacturer, from power to battery capacity, are overestimated and are not valid. In addition, in cheap models the engine life is often much lower than in more expensive options. You shouldn’t count on “maybe” and assume that repairing the engine or buying a new battery will not cost much. In fact, the price of a new battery is 35-50% of the cost of a new screwdriver. Now it’s clear why we recommend not seriously considering purchasing a cheap power tool even for household needs, not to mention using it for production purposes.

A screwdriver is a tool that every owner should have. Which screwdriver is better to buy for housework - consider the rating of the best and the rules for selecting it irreplaceable assistant on the farm.

First of all, you don’t need to chase the cheapest one, even if you only need the tool once. The manufacturer and model must be selected depending on the following technical characteristics of the instrument: speed, power, operating mode and other parameters. Next, we will present in more detail all the information about choosing screwdrivers and consider the most popular ones.

Modern screwdriver

A screwdriver is a universal device that is actively used in everyday life. The purpose of such a power tool is to tighten and unscrew screws and self-tapping screws.

There are dozens of models of similar instruments in stores, which are divided into several categories. Before choosing a screwdriver, you should determine the criteria and conditions under which it will be used.

The price range of the described category of power tools is wide, so everyone can choose a model for themselves according to their expected budget.

The choice greatly depends on the operating conditions. For home use Only technical parameters are relevant. For professional use, you will need more expensive and powerful versions with a removable battery.

Choosing a tool for home and work

To do right choice and buy a suitable screwdriver, you need to decide on the selection criteria. There are not that many of them, and the process itself seems simple, but in order not to regret the purchase later, it is better to clarify the nuances that may not be known to everyone.

The most important thing is to determine for yourself the frequency and intensity with which the tool will be used. If you need it to tighten several screws once or twice a month, the most budget model is enough. However, for more frequent use, you should choose more carefully and thoroughly.

A common mistake is to choose the cheapest model to use the tool for just a couple of days, but under heavy loads. For example, to assemble a metal structure (like a garage), or install fences in a country house, the first cheap one you come across the model will fit Not good.

The first question that buyers of such a device ask themselves is the type of power supply. Today, models are offered with a power cord (the tool only works from a 220 V outlet), as well as with a replaceable battery.

Before choosing the right battery-powered screwdriver, you need to determine in what conditions and for what purposes it will be used. The point is that battery power is limited, so high quality model A screwdriver with a power cord may be more powerful.

On average, one battery charge is enough for 100-250 screws. As the battery life increases, the power of the device decreases, which increases the tightening time and increases the load on the motor.

The capacity of the battery itself is also limited. The manufacturer indicates that it is enough for several hundred charge and discharge cycles, after which it will be necessary to purchase a separate component for a specific model.

Difficulty may arise if the owner has had the screwdriver for a long time, and this version is no longer available. Therefore, you will have to spend some time to find the right battery, identical in power and mounting.

Cordless screwdrivers also have their own advantages, which include autonomy. Network models usually have a cord up to one meter long. This is not even enough to connect the device to the nearest outlet, so you always have to use an extension cord.

If work is carried out outside the garage or home, additional expenses will be required. It is also difficult to work with a network tool at heights (for example, if you are assembling frames, tall furniture, structures, canopies, gazebos, garages, and the like).

Therefore, before choosing a cordless screwdriver, you must determine how important autonomy is to you. After all, corded power tools in this category can cost several times less than options with a removable battery.

Corded screwdrivers are more affordable. They have the same level of torque, regardless of operating time. The minimum rotation speed is 250-300 rpm. This is enough to drill holes in boards up to two centimeters thick and screw screws into them.

To work with thicker material, you should select more powerful model. The average value for difficult working conditions is 750-1300 rpm.

Specifications

To know which screwdriver to choose, you also need to have knowledge of the technical parameters of each category of power tool. Before choosing a cordless screwdriver, you need to pay attention to the type of battery. The duration of operation of the device on a single charge will depend on this and total term battery service.

The following types are distinguished: Ni-Mh (nickel-metal hydride), Ni-Cd (nickel-cadmium), as well as Li-Ion and lithium polymer (Li-Pol). In the first case, a large current can be supplied, but the operating life of the device is less than that of other batteries. Devices with a Ni-Cd battery have higher energy consumption.

Nickel batteries are used less frequently because physical properties they are prone to discharge if not used for several weeks. Lithium batteries more practical, but they are not without drawbacks. For example, in extreme cold, battery life is reduced by 30-50%. Optimal parameter in terms of capacity it is 2 Ah.

Pay attention to this indicator when choosing to ensure stable operation of the device for several hours.

In the description, the operating mode is most often indicated as “unstressed and reverse”. This means that the screwdriver can only be used in the standard mode of rotating the attachment in one or reverse side. The minimum power rating is 400-800 W.

For professional use, you will need 1000 W or more to ensure stable and smooth operation even under high loads. Low values are relevant for cordless screwdrivers that are intended for simple tasks.

Selection criteria

Cordless screwdrivers are selected by power, chuck type and bit rotation speed. In the first case, it is necessary to select models with a minimum power of 600 W, as indicated above.

It is also necessary to take into account the rotation speed of the nozzle. The higher it is, the smoother and more stable the drill or screwdriver will enter wood and metal. At low rotation speeds, it becomes difficult to work on metal, and the risk of motor overheating also increases. The diameter of the cartridge in most models is 10 millimeters, which is the standard.

In the list of characteristics there is an item about the type of cartridge. Today, quick-release or hexagonal chucks are distinguished. The first option is more practical in everyday use, since replacing the nozzle does not require the use of a separate hex key.

A single or double clutch chuck is tightened by hand. The first option requires less effort - this design is often installed on expensive screwdrivers.

The hex chuck requires clamping the bits with a separate key, which is included with the device. Additionally, such screwdrivers are always equipped with bits with different tips, which can be changed with one hand, and then tighten the connector with a small wrench.

When choosing, it is important to pay attention to the total weight of the tool. Models with a battery weigh 0.5-1 kilograms more than networked options, which can lead to inconvenience during long-term operation.

If a screwdriver weighs up to two kilograms, this will reduce the accuracy of its use and accelerate the onset of physical fatigue for the operator.

Few people notice such a detail as the position of the handle. Some power tool models have a standard “pistol” shape, while others have a handle offset to the center to stabilize the center of gravity. The second option is more convenient for frequent use - the load is distributed and centered in the handle itself, which requires less effort.

On today's market there are large number models of screwdrivers for every taste and budget. In order to accurately select a tool for your purposes, you need to familiarize yourself with the main advantages and disadvantages of specific options and the characteristics by which the division into types is carried out.

First of all, when choosing a power tool, you need to clearly define the scope of its use. Often, the household segment of power tools has a much lower cost than professional ones.

Second distinctive feature home appliances are their characteristics: such a tool may not have all the features of high-end models, it may not have increased power, performance or a rugged case, however, it is brilliant for everyday work in the home or workshop.

An amateur mini-screwdriver most often works with batteries, which makes it mobile and practical.

Professional models are designed for long-term work under heavy loads. Such large and heavy tools are usually powered, which ensures uninterrupted and long-term operation, provided there is stable access to the power supply.

Additional functions of screwdrivers

Manufacturers may add additional features for power tools. They do not affect the power or efficiency of work, however, if they are present, using a screwdriver becomes more comfortable.

Among these functions, we can highlight the presence of a backlight near the handle to illuminate the working area (simplifying the use of power tools in a dark place). Also worthy of attention is the pulse mode of operation, in which it is easier to work with soured screws and self-tapping screws.

Mains or battery

As mentioned above, electric screwdrivers are divided into two large groups: those operating from the mains and those that operate using rechargeable batteries.

batteries make devices larger and heavier, while network devices are characterized by lightness, but being tied to the place of use;
networked models are more often used for professional work, and battery-powered ones for short-term use;
If there is a stable connection, corded screwdrivers work for a long time without overloads or excessive heating, while cordless ones will have to be replaced or recharged;
The cord tends to get tangled when working with a network device; with a stand-alone model, you can forget about such problems.

The popularity of cordless professional and household screwdrivers is due to their ergonomic design, quality and independence in operation. Due to high demand, it is worth focusing on these models and considering the types of batteries used.

Before choosing a screwdriver for your home, garage or cottage, you should decide on its power source. Network models use the usual household network, and battery-powered devices are equipped with a removable battery. Each type has its pros and cons.

The cordless screwdriver is good for its autonomy. It is conditionally independent of the outlet and can be used even in an open field. This expands the scope of application of such a tool. However, the battery also imposes limitations.

The first of these is limited operating time. Usually the charge is enough for a hundred or two self-tapping screws, but in difficult conditions the autonomy is reduced. The second disadvantage is limited power (torque).

It may not be sufficient for working with hard and durable materials. There are positive exceptions, like the professional Makita DTD146Z, but they are not cheap.

A corded corded screwdriver is a tool with higher power and rotation speed. It does an excellent job of tightening screws and self-tapping screws, can be used in drilling mode, and due to the absence of a heavy battery, it weighs less. Constant source power supply allows you not to think about saving battery power.

However, you can only work with such a screwdriver away from an outlet if you have a long carrier or a generator. There are exceptions here too, but unpleasant ones: the cheapest Chinese models are no more powerful than their battery-powered counterparts, but they are also not autonomous. The minimum acceptable choice is something like the Dnepr DE-850.

Which screwdriver to choose – corded or cordless – depends on the needs and expected operating conditions. If the tool will not be used outside the house, apartment, garage or other premises, a networked one is better. It's cheaper for the same power, lighter, and ready to use anywhere, anytime.

The cordless screwdriver is optimal for outdoor use, including outside populated areas. At the same time, it is advisable to choose models with a capacious battery of at least 2 Ah.

Which battery type to choose?

Nickel-cadmium batteries

The undeniable advantage of this type of battery is its low cost. Ni-Cd batteries are most often used by manufacturers to create budget lines of power tools. Another advantage is the five-year warranty period, which exceeds the standard by 2 years.

Nickel metal hydrate batteries

They are characterized by a high level of environmental friendliness and are increasingly used in the production of high-end cordless tools. The dimensions and light weight of the batteries make the tool itself much lighter and more convenient. Perhaps the only drawback of Ni-Mn batteries is their high cost.

Lithium-ion batteries

These batteries are considered the best for mobile power tools. They hold a charge for a long time, charge very quickly, and they also do not have a charge memory effect. The only disadvantage of Li-Ion batteries is their high cost.

total voltage in different batteries ranges from 10 to 24 V, the power of the device depends on it and affects the duration of operation;
The material used to make the battery affects the capacity of the batteries;
loss of battery capacity due to the charge memory effect.

A cordless screwdriver, the price of which depends on the type of battery and other characteristics important for high-quality work of any complexity, is a sought-after tool in every home.

Power and torque

The second thing to consider before choosing a screwdriver is its power and torque. Very often, sellers indicate power, but do not indicate the torque of the model and are silent about the power of cordless tools.

With power, everything is quite simple: 600-800 W is more than enough for non-professional (home) use, if you don’t also need to do a lot of drilling. But the torque is worth considering in more detail.

The torque (measured in Newton meters - N*m) of a screwdriver determines how much force it can apply when tightening a screw. The higher this value, the harder and stronger materials the screw will go into. If there is not enough torque, the transmission mechanism of the tool will slip and the screw will get stuck halfway.

In order to tighten small screws (up to 50 mm) in not very solid wood, any screwdriver is enough. However, to work with hard wood, it is necessary that the torque be at least about 15 N * m. For longer screws and self-tapping screws, you need 20-30 N*m, and models with 40 N*m and more will cope with screwing “hundreds” into solid timber.

Rotation speed

For a household screwdriver, rotation speed is not a fundamentally important parameter. The tools are equipped with a reduction gear that converts high speeds on the motor shaft to low speeds on the chuck.

A couple of hundred revolutions per minute is enough for screwing, but a high rotation speed can cause the bit to jump off. This leads to both premature wear of the nozzles and licking of the slot of the screw head.

Before choosing a screwdriver with drill functions, you still need to pay attention to the speed. When working with hard materials there are never enough of them. 1000 rpm is the minimum suitable for materials of similar hardness, and 3000 rpm will not hurt.

Chuck type

Another point that needs to be taken into account when deciding which screwdriver to choose is the type of chuck. A universal solution is a quick-release chuck, in which the bit is secured by rotating the clamping ring.

It allows you to use not only bits, but also drills and heads for tightening nuts. You can also insert a mixer attachment into a similar cartridge for mixing the solution, or an umbrella sanding brush.

The hexagonal chuck for bits is good because it reduces the weight of the tool and also allows you to quickly change attachments. They are held in it by a special retainer or magnet and can be removed with a little force. However, a drill cannot be inserted into such a chuck.

There are exceptions - these are models that are also equipped with a removable quick-release chuck. They are the most versatile, since they are easier to twist screws and can be used for other purposes.

Review of popular brands

How to choose a cordless screwdriver, which company is better? To simplify the final choice of model, it is necessary to indicate the most popular brands under whose logos modern power tools are produced. Durability and cost partly depend on this, so choosing a specific manufacturer should not be neglected.

Makita is a Japanese company that produces high-quality power tools (founded in 1915);
Dnipro-M is a Ukrainian manufacturer that develops and manufactures power tools in an affordable price segment (most models are produced in China);
Bosch is a German company that does not require a separate introduction;
Vertex is a power tool company in Taiwan;
Forte is a certified Ukrainian manufacturer of power tools.

Conclusions

To immediately know which screwdriver to buy for your home or work, you need to study the working conditions described above, as well as the factors for choosing a tool. The following is an objective list of the advantages and disadvantages of each type of device.

Maintaining rated power, regardless of operating time;
Ability to work unlimited time without breaks to recharge;
Lower cost of power tools compared to battery versions.

Difficulty working at heights (it is difficult to hold the tool level along with a long wire and extension cord);
You cannot work without an extension cord and a 220 V socket ( work area in this case it is limited to a few tens of meters from the outlet).

Based on the list of advantages and disadvantages, it is relevant to say that a corded screwdriver is optimal solution for an apartment or private house. In this case, you need to stock up on an extension cord of 5-20 meters to ensure freedom of movement with a power tool in your hands.

The average resource of such devices is not limited. According to users, on average one model can withstand 2-4 years of active use.

Possibility of remote work, regardless of the proximity of the outlet;
Possibility of developing high speed of the nozzle.

Disadvantages include limited operating time, limited battery capacity and weak power of cheap models.

If you need a device without a network cable for work or at home, it is more important to take high-quality, expensive options cordless screwdriver. This will reduce the time required for charging and provide consistent power even when working with hard materials.

Sooner or later, home owners are faced with such a need as using a screwdriver. It is necessary when you need to assemble furniture, replace a lock, hang a picture, fix drywall or baseboards, install a door, and in many other everyday situations. Those who consider borrowing an instrument from friends or neighbors a bad habit will most likely go out and buy their own. But what should a person who knows little about screwdrivers do? Is there a lot of work ahead with this equipment at home? How not to make a mistake with the necessary parameters and which screwdriver you should choose for your home - this will be discussed further.

There are two types of screwdrivers: cordless and corded.

Let's decide what kind of work the device will be used in most often?

If you go to any power tool store, it will become clear that choosing a screwdriver without knowing absolutely nothing about this type of tool is not an easy task. Because its offer is huge. There are many manufacturers of such equipment, competing with each other and positioning their product as the best. An ignorant person's eyes will run wild from the variety of this proposal.

Therefore, the most fundamental criterion when choosing this tool is the feasibility of its use.

If the device will be used for one-time repair work around the house, then you should choose inexpensive model with a minimum set of functions.

If the equipment is planned to be used in a home workshop and will have to be used frequently for certain highly professional tasks, for example, drilling metal, then its range of functions should be quite wide.

What technical parameters should you pay attention to first and which screwdriver should you buy?

Return to contents

Battery or mains?

Keep in mind that there are both battery-powered and mains-powered models. Which screwdriver is better to buy for your home? Rechargeable ones are convenient to use due to their mobility, they are not tied to the network, they can be carried with you anywhere. No need to think about the length of the wire, the presence of sockets, extension cords, and so on. But for the smooth operation of such a tool, they need to be recharged, which will waste time. Corded power tools are indispensable when working with metals.

If the choice is made in favor of a cordless screwdriver, then you should also select the type of battery. There are three types of them: lithium-ion and nickel-cadmium, metal hybrid. Here they are presented in descending order of reliability, price and time to recharge the battery.

Lithium-ion batteries are considered the most practical. They cost more than their counterparts, but they stand out for their capacity, the ability to be used for a long time between recharges and their low weight. Their working condition is 3-4 years, after which they become unusable. They are unpretentious to use and require regular care.

Battery power (9.6 - 24 volts) is an equally significant factor when choosing a screwdriver. High power is possible long work device without recharging, and also screw screws into the most problem areas. High power is a sign of a heavy device.

Torque also deserves to be taken into account when purchasing. Household work can be performed at 10-15 Nm. It will be sufficient to buy a screwdriver with 40-40 Nm. Although some of its types can reach 130 Nm.

Rotation speed is another important point when choosing a screwdriver and buying the one you need. The drilling speed will depend on this value. Therefore, to drill more hard materials, you need to choose a tool with high torque. To tighten a self-tapping screw on the farm, 400 rpm is enough. For professionals this value will not be enough. They will need from 1200 and above rpm.

When purchasing, take into account how comfortable it is to hold the device in your hand. Comfortable? So he's yours.

From time to time in the household there is a need to drill a hole, tighten up loose furniture, or mix glue or mortar. To do this, do not purchase three tools: a drill, a screwdriver, and a hammer drill. Buy one corded screwdriver with a drill function, and all problems will be solved quickly and efficiently. Such a tool, unlike a battery-powered one, has more power, better performance, works long time without requiring recharging.

How does a corded screwdriver work?

Power tools of various brands and manufacturers are endowed with many technical characteristics, functions, and housings that are different from each other. However, their design and basic operating principle are almost the same. The only difference is small nuances. The photo shows how corded screwdrivers look from the inside:

It bears the following markings:

Start button.
Reverse switch.
Capacitor.
Electric motor.
Frame
Gearbox
Cartridge.

The screwdriver is powered by a 220 volt network and is equipped with a motor DC. The reverse button changes the polarity of the power supply, as a result the motor rotates in the opposite direction and the device turns out the screws instead of screwing them in. Gearbox parts are made of metal or technical plastic. An electric screwdriver acquires additional operational functions when equipped with a two-speed gearbox. A speed of up to 450 rpm is needed to work with self-tapping screws and screws, and rotation at a speed of up to 1400 rpm allows you to drill holes in metal, wood, and plastic.

Advantages and disadvantages of a corded screwdriver over a cordless one

The fact is that both of them have a lot of advantages, but are not without disadvantages. The equipment is not cheap, especially when it comes to branded models. Therefore, make your choice of a corded screwdriver after thoroughly familiarizing yourself with the item you like.

Corded screwdrivers are lighter in weight and smaller in size than cordless screwdrivers. Because the battery inserted into or attached to the body makes the tool heavier and increases its weight.
A 220 V screwdriver does not lose power during operation, while a battery-powered tool gradually loses it in parallel with the decrease in battery charge.
Depending on the power supply conditions and the characteristics of some brands of batteries, it may happen that while charging them, you have to stop all other work. A powered drill/driver will not allow this situation to happen.

Price also matters. The best corded screwdriver costs much less than its cordless counterpart.

What to look for when buying a tool

When you stop in front of a display case or look through a catalog, it is clear that it is impossible to immediately fix your gaze on a decent device. First, you need to know exactly two things: why we are buying and how much we can expect. Since you can choose a corded screwdriver of decent quality only by knowing its long-term tasks in advance. At the same time, it’s good to understand what the most important parameters should be paid attention. Of these we denote:

Power. The weight of an electric drill-driver and its productivity depend on this indicator. For home use, a power of 450-650 W is sufficient; professionals need a more powerful tool.
Torque. Characterizes the force with which the device is capable of working. This value affects the choice of material and the size of fastening devices that can be used with this tool. For household work, a torque of 25-30 N*m is sufficient.
Reverse. Its presence is mandatory when a networked home screwdriver is needed not only for tightening fasteners, but also for removing them.
Rotation speed and mechanism for its regulation. Changing the indicator makes it possible to use the tool in different conditions.

Comfort during operation. This includes light weight, comfortable grip of the handle, cord length and other properties that allow you to create best conditions at the workplace.

The main thing is not to confuse a screwdriver with a drill. It is believed that if the device has a battery, it means a screwdriver, and if there is a plug, then it means a drill. This is not an argument. The main difference is constructive solution. When the start button is pressed, the screwdriver chuck stops instantly. While the drill continues to spin for some time.
