When choosing a screwdriver in front of the consumer, the question immediately arises - what is better: network or rechargeable? Consider the option with the acquisition of the network tool and its advantages over its autonomous fellow.

What is the differences between the rechargeable and network screwdriver

The main advantage of the accumulator screwdriver is the presence of an independent power source that provides mobility and maneuverability to the operator. You can work in remote places, in areas where there is no connection to the power grid.

But these tools have their drawbacks.

Autonomous power supplies in them are sufficiently heavy, especially nickel-cadmium. Because of their presence, the dimensions and weight of the device are significantly increased, which makes not very convenient bulk operation with the device at height.

Batteries need to be periodically changed and recharge. This takes time and requires connection to the power grid. So long-term work in remoteness from the permanent source of electricity is limited to the battery capacity.

The most powerful, which are not suiced, are designed for continuous work only up to 2-3 hours. The recharge of batteries often takes time more.

Batteries have a limited period of functionality, and long-term storage reduces their charge. After a certain time, you will have to spend money on new power sources.

The price of autonomous screwdrivers, especially with high-power batteries, higher than on network tools.

Nickel-cadmium sources, the most powerful in terms of the number of charges (up to 1000) and therefore applied more active than others, distinguish harmful substances.

Network for the screwdriver provides higher performance and greater continuity of the work performed. And at home the autonomy of the operation of the screwdriver sometimes does not have a decisive value.

Uninterrupted nutrition means that the device will not lose power in the process of continuous operation during the day.

Lightweight design allows you to perform significant amounts of work, including at the height.

Network screwdriver without problems will work in the cold.

Well, finally the price. A good network screwdriver is significantly cheaper than the rechargeable analogue.

The main technical characteristics of network screwdrivers

The technical characteristics of the screwdriver define it functionality. How long and reliably it will work, what operations they can be produced as far as it will be in operation and so on.

Power

This is the main indicator affects the performance of the instrument, as well as on other parameters of the tool, such as speed and moment of force. For long-term and various works, you need a device that is more powerful for home conditions, a 400 watt engine is quite enough.

If you need a drilling function, you will need a tool with a power of 550-600 W. Machines with greater power are more discern and consume more electricity.

Torque

Measured in Newton meters (nm). Indicates the power with which the device will affect the screwed screws. This indicator determines, with screws of which diameter and how long the screwdriver will cope.

So, with a value of up to 30 nm, they can be screwed into the wood screw to a depth of 70 mm. For fastening elements, the moment of force should be 40 nm or you must first drill the hole.

At the screwdelt this feature Is main and indicated always. Coma of that reliable manufacturers in descriptions call the maximum allowable fastener diameter for specific materials.

Speed \u200b\u200bspeed

In household instruments, this indicator is 400 rpm. To perform the functions of the drill, higher revisions will be required (1300-1700 rpm). High revs are especially needed when working with iron.

Changing the speed is carried out on different models either by pressing the on key or adjust the wheel located on the button. In the screwdriver drills, the turning mode change toggle is installed.

Reverse

Necessarily present on all the screwdrivers. Provides a change in the direction of spindle rotation and, accordingly, the function of unscrewing screws. Switching rotation modes is made with a button that is often located next to the start key. A slightly reliable option looks like a plastic lever at the top above the key that can easily break down.

Locking button

It may be useful only in screwdriver drills.

Shape of the housing

The housing can be made in the form:

Pistol. Characteristic for budget models. Such a housing is convenient to press on the self-tapping screw during screwing, which have to be done due to the weak engine power.

T-shaped. In this case, the handle is shifted to the center of the housing. According to manufacturers, such a configuration does not strain the hand in the process of work.

Traditional drill. This indicates the presence in the apparatus of the gearbox, other metal parts, which is inherent in powerful profilestruments and drillers. Such devices have to often support the second hand, as their weight is approaching 3 kg.

Types of network screwdrivers

As we have already found out, network screwdrivers are divided into devices only with the function of screwing-out screws and devices endowed with a drill function. On the second, you can set a drill mode at a higher speed - up to 1500 rpm.

These devices differ in the type of cartridge in which nozzles and bits are attached. By its design, the cartridge clips are divided into the following types:

The gear or key cartridge in which the nozzle shank is fixed and is finally fixed by a special key. Such a fastening is considered more reliable;

Flexible cartridge (BZP), in which the attachment of the nozzle is performed by manually rotating the clamping sleeve. The shift of the nozzle is carried out in a matter of seconds.

Magnetic hex cartridge. The bit into it is simply inserted, it is not necessary to twist anything. As a result, the disadvantage of this attachment is a light backlash bits.

The main characteristics of the cartridges include their diameter. More allows you to use nozzles help. For household tools, a maximum value of Ø up to 20 mm is sufficient.

If the screwdriver is not suitable for specific operations, you can use adapters. The cost of their low, on sale is always a sufficient assortment.

To decide which screwdriver to choose, decide on the circle of tasks to be performed. For fastening self-tapping screws in wooden designs Suitable small power supply apparatus with quick-sample chamber. The screwdriver drill is useful for drilling in small volumes. To fulfill more serious work on drilling, especially metal, it is better to purchase a separate drill.

Network screwdrivers, in contrast to models with an autonomous power source, provided under certain conditions a greater performance and continuity of work. Look below, we consider which network screwdriver is better when carrying out repair and finishing work At home, assembling furniture, etc.

The most important characteristics of the screwdriver

When choosing a screwdriver, attention should be paid to the most important operational parameters Devices. Among them can be allocated:

1. Power. Determines the performance and weight of the power tool. Household applied screwdrivers usually grabs 450-650 W.
2. Torque. Directly determines the performance, characterizing the effort that provides a tool when rotating the bits. The point value determines the material with which the screwdriver can operate, as well as the length and diameter of the fastener.
3. Reversive mechanism. Its presence allows you to extract fasteners.
4. Rotational speed, Ways to regulate its value. Determine the possibility of using the device in different conditions.
5. Ergonomic - Comfortable grip, low weight and other characteristics responsible for the comfort of operation of the power tool.

The usual electric household screwdriver with a capacity of up to 300 W is able, for example, into a thin metal surface to screw the screws. More responsible work require power tools with a capacity above 650 W. Such devices will refer to the category of professional, the power of which reaches 850 W.

Torque household tools It is usually 25-30 N * m. This allows B. wooden base Split about 70-millimeter screws. If there is a need to work with more powerful mounting elements, it is advisable to use devices with a torque of at least 40 N * m.

The rotational speed of the screwdriver's cartridge in most models is 0-800 rpm, which is quite enough when working with fasteners. This feature is adjustable, but in different devices Changing the speed can be done by changing the force of pressing the button or the installation of the desired value of the regulator or toggle. In the course of performing a large amount of single-type work, the second version of the speed control is preferable.

Types of network screwdrivers

Devices differ in the type of cartridge - the mechanism of holding nozzles (bits):

• Devices with gear (key) cartridge, in which the nozzle is attached using a special key. This process requires a certain time and effort, but this option Fastenings are characterized by high reliability.
• A screwdriver with a quick-chase patron is a very convenient mechanism in terms of lightness and speed of shifting nozzles, however, in working with solid materials is not reliable enough. There are single and two-fledged cartridges with one or two rotating rings.
• The cartridge under the bits is equipped exclusively to the screwdrivers, while the types of cartridges have already been described are also applied in the drills, screwdriver drills, etc.

Also, devices differ in the diameter of the cartridge, on which it depends on how powerful the nozzle can be used in operation. Unprofessional power tools is usually equipped with a cartridge with a range of 0-20 mm.

How to choose a network screwdriver with a drill function implemented in the device, you also need to know. These power tools are called drill screwdrivers. Unlike simple models They usually have two speed adjustment ranges:

• from 0 to 400 rpm - work with fastening element;
• from 400 to 1300 rpm - when drilling.

The power tool in question can also be structurally different with the type of engine - with or without brushes. The second more expensive, although they work more smoothly, with low noise and do not require special maintenance (brushes quite often need to be changed, so some manufacturers even complete their power tools with an additional set).

The best screwdriver in solving most tasks is a combination, which made the advantages of not only network, but also battery devices. It works both from the network, having enough power even when driving solid materials and from its own battery, without needing in access to the outlet.

Choose a screwdriver correct

The main thing is to pay attention to when choosing this power tool - the power and the associated torque. For home and work, for example, with furniture, when it is necessary to spin relatively small screws or assemble some element, it will be enough for a screwdriver with a torque from 10 to 30 N * m.

Wood drilling can already be carried out by a screwdriver with wider capabilities and a moment corresponding to 30-40 N * m. If one of the purpose of the tool is the drilling of brick, concrete or metal surfaces, then the torque of the screwdriver must exceed 40 N * m.

What a screwdriver is acquired, you need to decide in accordance with another characteristic. Manufacturers usually indicate the specifications on the maximum fastener diameter with which this screwdriver can work. Most devices are 5 mm, although there are models that can twist 10 and even 12-mm fasteners. In devices with a drill function, an important parameter - the largest diameter drills. It can also be up to 13 mm in separate models.

Try to buy such a tool with which you could comfortably work and safely work. Auxiliary functions are implemented in many devices:

• blocking the power button;
• backlight working area using a LED flashlight;
• reverse mode when unscrewed fasteners.

Also, the convenience of work affects, for example, the presence of an additional handle in the center, rubber cover Handle preventing tool slide.

The best models of network screwdrivers

Below will be considered to choose a screwdriver - high-quality and inexpensive household or semi-professional. Consider the characteristics of models including domestic.

A domestic inexpensive 260-watt unast drill-screwdriver, weight has a small - only 1.4 kg, convenient to use. Handle with anti-slip overlays, the type of cartridge is quick-release. Torque with a maximum value of 25 N * M - adjustable. Speed \u200b\u200bmode - two-position.

Pretty powerful B. household use 350-watt unstressed screwdriver with a drill function. The cartridge quickly has a function of reverse and electronic speed adjustment of rotation. Weigh the device is only 1.2 kg, the housing is plastic reinforced with fiberglass. Maximum torque 12.3 N * m, maximum turns of 4000 rpm.

Easy and compact, at the same time, a powerful household drill screwdriver with a torque of maximum 38 N * m and a rotational speed of 1600 rpm with electronic adjustment. The kit includes a case, a set of bits and drills. The six-meter network cable allows you to work without using extension cords. To decide which network screwdriver is better in comparison with a semi-professional inexpensive model.

Semi-professional very inexpensive model domestic production. The power of the screwdriver with the function of the drill is 500 W, the speed of rotation of the quick-pressure cartridge - 2600 rpm. Sold with a set of additional brushes.

How to choose a screwdriver (video)

From the video presented, you can learn what the network screwdrivers are different using the example of four selected models:

What a screwdriver is better to choose depends on the tasks solved using this tool. Simple work On the installation of the fastener can be carried out using an inexpensive network screwdriver of low power with a quick-inspection cartridge. If, in addition to standard tasks, it is possible to periodically drill holes in the metal, wood and even concrete, you can choose a sufficient power drill and with a reliable key cartridge.

In contact with

Electric screwdriver is one of popular toolsI certainly heard every person. This tool must be at the disposal of any host, because it is possible to use it for execution. different work at home. With the help of a network screwdriver, you can tighten a variety of bolts or screws in seconds, very often screws.

Sometimes there is a need to collect new furniture. Use for this of different kind Screwdrivers is very uncomfortable, and time this assembly will take a lot. In such a situation, the screwdriver will be simply an indispensable tool. Many modern network models of screwdrivers can be called quite cheap, while they have good specifications And you can use them for many years (unless, of course, to properly exploit them and care for them properly).

Content:

Despite the fact that the choice of electrical screwdrivers is very large, determine which is optimally suitable for you, sometimes it is not easy, especially if you do not understand this tool at all. During the purchase you need to take into account many nuances, starting at how often you are planning to use the tool and which is exactly the goal.

Network screwdriver which is better to buy for the house - this is a very relevant question and if you can not independently do right choiceThe decision of this problem will help you with the decision of our experts.

Advantage and disadvantages of network screws

If there is a question about what differences between the battery and the network type of the power tool, then the most important thing is, of course, the method of powering the tool. Today, most try to buy. After all, they allow you to work anywhere without any restrictions. This means that before starting work, you do not need to look for sockets indoors or use several extension cords to perform one or another manipulation.

At the same time, the power of the screwdriver may differ and due to the fact that different types of battery are installed in the tool. Today there are three different types batteries, namely:

1. lithium-ion (Li-Ion);
2. nickel-metal hydride (Ni-MH);
3. nickel-cadmium (Ni-CD).

Specialists suggest that the lithium-ion type of battery can be called the most environmentally friendly. At the same time, the tools with such a battery are very poorly transferred to sufficiently low temperatures.

How to choose a video screwdriver

Nickel-metal-hydride view is able to withstand no more than 500 charging, and nickel-cadmium in turn - a little more than 1000. Thus, the second option is quite popular among users from both professionals and those who take the tool for home use. It is very important to remember one negative point: the cadmium is very harmful to the human body, and therefore the long-term use of a screwdriver with such a battery can cause health problems.

To date, you can find tools that are quite capable of supporting several different types batteries and fully work on them.

What network screwdriver is better to choose professional or household?

Most people are confident that if and buying any technique, then your choice must be stopped exclusively on professional. Of course, such a solution can be called logical, but not always such a technique will work quite well at home. Professional screwdrivers have quite a lot of positive moments to which the following can be attributed:

1. such tools are more reliable, and their life is larger;
2. they have a few times the best technical characteristics;
3. included with a screwdriver for sale a much more powerful special "charger", with which you can quickly charge the battery of the power tool.

At the same time, it was not without flaws:

• The cost of the tool. Even if you take into account very big competition, the price of professional tools will still be much higher than that of the usual household model.
• The weight of the professional apparatus is also, as a rule, more than the domestic, which does often work with a tool is quite heavy and uncomfortable.
• Most of the technical characteristics of a professional screwdriver may be unnecessary or superfluous during the use of the tool at home.
• As a rule, if you plan to use a tool exclusively at home, then the household appliance will be more than enough, because a professional tool is nothing but an unnecessary overpayment of money, which can not justify yourself.

The main technical indicators of any power tool is made to attract the power of the tool, torque, reverse, speed of rotation, adjustment of the number of revolutions, ergonomics, as well as type, cartridge size.

The higher the tool will have power, especially high levels Performance he can boast. At the same time, you need to remember that quite powerful screwdrivers have a lot of weight and work with them will not always be convenient.

In addition, it is worth saying about torque or about strength that affects the tool and makes it rotate. Depending on the this indicator You need to choose the size of bolts and screws with which the tool will be able to work. At the same time, this affects the quality of materials that can be treated with an electric screwdriver.

Each of the characteristics plays a big role and it is necessary to consider when choosing a tool for home use. Do not forget that you need to examine else that will be used when working with a network screwdriver. Experts recommend buying a ready-made set, which will make the work simpler and necessary nozzle will always be at your hand. Choose more expensive and high-quality products, because it will allow the nozzles several times longer. As practice shows, there are enough cheaper analogues only for several applications and then you need to buy new ones.

To date, the choice of power tools in any construction store is so big that it is very easy to get confused. But at the same time there are certain manufacturers who have already deserved trust and their products can be called one of the best. The most popular manufacturers of power tools in modern world It is customary: Makita, Bosch and Hitachi. The tools of these companies are distinguished by their reliability, serve long enough, although the cost of their little is high.

For home use, cheaper manufacturers of network screwdrivers will be suitable. For example, such a German manufacturer as DeWalt and a company from America - Black & Decker have proven well.

Soviets Experts on choosing a screwdriver video

Which network screwdriver it is better to take for home only after considering all the technical characteristics of the tools. In addition, it is advisable to compare several models. If you do not understand this question at all, then consult with the seller who will tell about all positive and negative moments This or that model of the screwdriver.

Screwdriver is an indispensable tool for both professional builders and any man engaged in small-scale household repairs. The main thing is that at the right moment this tool did not fail. How to choose a screwdriver will tell this article.

Where does the selection of the screwdriver begins

Choose required tool It is not difficult, the main thing is to take into account several aspects:

• Tool functionality,
• Specifications,
• Varieties of screwdrivers,
• Additional functions.

Screwdriver is functional instrument. It is not necessary to spend time on manual twisting or twisting screws, and therefore it will become a good helper and in assembling / disassembling furniture, and in any installation work, and in drilling various materials.

Given these functions of the screwdrivers, when purchasing it is important to think about the maximum diameter of the screw. Standard size diameters - 5 mm, but some models diameter reaches 10 or 12 mm. The difference is quite significant. The same applies to the diameter of drilling.

To better understand why the parameters choose a screwdriver, you need to at least know how it is arranged.

How to choose a video screwdriver:

Device screwdriver

The main nodes at the tool are a bit, and the device itself consists of:

• Battery, which consists of a whole set of batteries. All these elements combines one housing.
• Gearbox. It may be simple-called gear wheels in the amount of several pieces or planetary. The planetary in turn can be a single-stage or two-stage. Such a gearbox has a more complex mechanism of work.
• Regulatting systems.
• Engine providing permanent current, which is represented by a cylinder with permanent magnets,
• Systems that limits the load.

Its technical characteristics will depend on these tool parts, which should pay much attention when buying a screwdriver.

What technical characteristics of the screwdriver need to pay attention when purchasing it

Characteristics of the screwdriver will depend on its type. It is customary to distinguish between two varieties: a screwdriver for professional work And for housework. They differ in features, scope and use frequency. A professional screwdriver is highly powerful and produced for serious loads.

Note!

Amateur tool does not differ in functionality, but his work is not as fast and not so frequent, therefore professional builders He will not suit.

Household screwdrivers are most often accumulative and easy, and with homework Cool pretty good.

These two types of screwdrivers have different specifications, namely they differ in power and speed. Power is measured in a torque moment, an amateur tool is within 10-15 nm, and at a professional, in the region of 130 nm. Speed \u200b\u200bis measured in turnover, at the first it is about 500 revolutions per minute, and the second is about 1300 revolutions, which allows it not only to twist the bolts, but also to drill holes in various material.

Also on recharge, they need different amounts of time. A professional screwdriver charges in 1 hour, and household for 3-6 hours. More regulatory levels are different, from 5 to 22. Amateur many adjustments are not required, and professional work on the maximum capabilities.

Rechargeable screwdriver

Construction I. mounting work often pass in places remote from the electrical. Rechargeable screwdrivers come to the rescue. You can easily produce high-altitude work and work on those objects where there is no electricity yet. In addition, it does not have to drag the wire everywhere.

Another advantage of the battery tool is its weight, it is easier than the network.

When buying such a tool, it is worth considering that from time to time it is discharged and it will have to be charged. Therefore, it is better to immediately buy a second battery. At the same time, the price of the battery itself can be quite high.

The answer to the question: "What rechargeable screwdriver Better "will depend on its manufacturer and from the type of battery itself. The most reliable rechargeable screwdrivers in the following manufacturers:

• Metabo
• Makita,
• Hitachi.

The battery itself in the screwdriver can be three types:

• Nickel-cadmium
• Nickel-metal-hydride,
• Lithium-ion.

Varieties of screwdrivers

They differ in:

Number of charging. The first is usually withstanding about one thousand charges, the second is about five hundred charges, well, and the third battery is considered the most capacious.

Availability. The first two species have a memory effect with a reduced battery capacity due to incomplete charging.

In resistance to temperatures. Nickel Cadmium is not afraid of frosts, and they can safely work on the street in winter time of the year. But the last two types of batteries are afraid low temperaturesAnd for work in the cold are not suitable.

Safety level. The most environmentally friendly is a lithium-ion battery.

Battery Charger

To charge a battery screwdriver, be sure to need charger. They are two species: standard and impulse.

Standard charging is suitable for household screwdrivers.

Note!

To fully charge the battery with such a charger, it will be necessary from three to six hours.

Pulse charging is suitable for professional screwdrivers. Such chargers have increased efficiency and charge the battery in just an hour.

Proper battery charging must pass at a certain temperature mode, from +10 to +40 degrees. Usually the battery during charging is very heated, so requires cooling. Determine whether the battery charge will help a special light indicator. The scheme of the charger of the screwdriver is not completely complicated, so when it is damaged, the charger can be repaired independently, using special literature.

Screwdriver

Network screwdriver

A rechargeable screwdriver, of course, is very convenient to use, but also cost quite expensive. Network screwdrivers are more affordable. In addition, many such a tool will seem more reliable.

In general, network screwdrivers have quite a few advantages: reliability, reliability, high power, durability and possibility of continuous operation. But with all this they have one big drawback: affection for the power grid. Of course, this is not a disadvantage when work is carried out in the room, close to the source of electricity, but with high-altitude work, for example, on the roof of the house, it becomes a big minus.
