What characteristics to choose a screwdriver.

How to choose a screwdriver

Scurgery. A universal power tool, used to tighten fasteners and drill not very solid materials: wood, plastic, drywall, thin sheet metal, etc. Non.Standard use of screwdrivers. Drilling holes in ice on winter fishing and mixing not very thick building mixtures.

The screwdriver is considered a multi.Purpose tool, as it finds use in different types of work: repair, finish, grinding surfaces, assembly of furniture and various designs, work with drywall, wood, etc. The device can be used both indoors (in the apartment, in the country, in the garage), and outside.

The design of any screwdriver is the same: an electric motor with a gearbox transmitting rotation to a spindle and equipment, a cartridge of a certain type and an electronic control system. There is also a clutch that regulates the torque, and the battery (in battery models), which supplies the tool for the tool. The choice of the tool that is optimal for your needs should be approached thoroughly. What screwdriver to buy for home or professional use, our article will tell.

Important characteristics of screwdrivers

Based on these parameters, you can choose the best model for yourself.

Type of battery

– Today it is the most popular type of battery, which is everywhere used in technology. From cell phones to electric vehicles. It is very reliable, powerful, holds a charge well, has an increased resource of charging/discharge cycles, does not have a memory effect. Suitable for frequent use. However, lithium screwdrivers are more expensive than analogues. By the way, the inventors of lithium-ion batteries in 2019 awarded the Nobel Prize in Chemistry The battery “from the past”, today is installed mainly on household models of screwdrivers, which are used from time to time. Their main advantage is low price. A serious disadvantage of such batteries is the memory effect: if you put the planted battery on the charge for the charge, then its maximum container will slightly decrease. If you continue to charge a half.Discharged battery, then it will soon develop its resource ahead of schedule and will fail. Another minus of this type of batteries is their non.Ecologicality. After all, the cadmium is recognized as unfavorable for health and the environment with metal. Therefore, the use of nickel-cadmium batteries will require special care advanced type of nickel batteries. They work perfectly in conditions of negative temperatures, the memory effect is more pronounced than the nickel-cadmium. However, such batteries seriously lose the lithium-ion-ion-ion-ion-ionThe last generation of lithium-ion batteries developed by Metabo specifically for power tools. According to the manufacturer, they are more compact and easier than ordinary lithium-ion elements, and also give out the maximum power, not inferior to power supply from the network.

Engine’s type

– The most common type of electric motor in tools and household appliances. From the current source, electricity is transmitted to the engine using sliding contacts on which special brushes are installed. Brushes are a consumable that we wear out over time and requires a replacement. In some models, it is impossible to quickly replace the brushes and the screwdriver will have to thoroughly disassemble. The main advantages of the brush engine are simplicity of design and low price a more productive electric motor, with high efficiency. There are no moving elements in its insides, and the current transmission is regulated by the semiconductor switch controlled by an electronic sensor. Brightless engine tolerates increased loads well, wear.Resistant and in good condition does not spark. However, it significantly increases the price of screwdrivers.

Food from the battery, type of cartridge fast.Sounding, torque 9 nm, max. Rotation speed 550 rpm, capacity 1.1 ah, voltage 12 V, illumination of the working area, weight 1.32 kg.

Type of cartridge

Special nozzles (bits) are fixed in the cartridge, with which a screwdriver works. There are several types of cartridges in the models presented on the market:

– The most common. Allows a pair of movements to change the bit;
• Magnetic. Bits are held due to magnetic force. Due to the unreliability of such fastening, it is most often used in electro.Opticals and low.Power screwdrivers;. The nozzle is fixed in the cartridge, and then delayed with a side gear key, as in electric drifts and perforators. This is the most reliable type of mount. Naturally, to change the bat will have to spend some time;. Approaches certain types of bit. Allows you to quickly replace them.

The power of the screwdriver

Its performance directly depends on the power of the power tool. For screwdrivers, this means what moment of strength to be attached to unscrew the screws or check the surface. This value is measured in nm (Newton-meter). The higher it is, the more power the device clamps the bolt and cope with the fastener of a larger diameter. However, excessive torque can damage the nozzles, so in many models it can be adjusted with a special coupling. If it is supposed to work with small fasteners, then there are enough screwdrivers with a capacity of 10-15 Nm. These are typical indicators for electrical buildings. The capacity of professional models is located around 25-30 Nm. With such a tool you can calmly twist screws up to 7 cm. The models of the class are higher than the force of about 40 nm, can cope with long self.Tapping screws and even drill small holes in not too dense materials. The power of professional screwdrivers can reach 130 Nm. They can drill holes in dense materials, used, for example, when installing stretch ceilings. Powerful screwdrivers, as a rule, work from an electric network.

Speed ​​(or frequency) of rotation

This is an important characteristic that shows how speed the cartridge will rotate with the nozzle. The general rule is quite simple. At a lower speed you can drill a denser material or unscrew the screws of larger diameter. Unit of measurement. Turnover per minute (rpm).As a rule, the speed of rotation of the cartridge is regulated by pressing the start button (trigger). In some models, the speed of rotation can be set by a special gearbox. High frequency is used for drilling, low. For installing fasteners. So, for twisting screws, a speed of about 500 rpm is suitable. On the contrary, so that the drilling is comfortable already required 1000-1500 rpm.

Popular manufacturers and their solutions

To the question of what the drill of the future should be in the company Metabo They answer simply: small.Sized, flexible in terms of use, wear.Resistant and multifunctional. And today they produce a productive tool with an ergonomic design. The Metabo BS 12 Nicd battery screwant is equally effective for drilling different materials and working with different types of fasteners. The capacity of 1.7 a/h and the voltage of the battery 12 V provide the necessary duration of work, including with a rather large equipment, for example, for twisting screws of 5×100 in a beam. Adjustment of the torque from 1.8 to 5.2 nm makes it possible to choose the optimal mode of operation, and two.Speed reverse. To unscrew the screws and free the stuck drill. The kit comes with a case and an additional battery. This tool will approve of furniture and builder, who is engaged in specialized drywall false structures.

Company Makita It has been working since 1915 and today is a leader in the development of tools for construction. The success of the manufacturer is ensured by two simple rules. Constant adaptation to the conditions of the developing market and the highest level of product quality. Take, for example, the battery drill Makita 6281DWPE. The ideal option for household work is one of the most compact models in the line. With a battery capacity of 1.3 a/h and a voltage of 14.4 B, the model develops a torque of 36 nm. At the same time, the number of torque installations reaches 16. Is this not evidence of the manufacturer’s desire to create products that meets the requirements of users.

Company Ryobi Developed a special instrument for the Ryobi ONE technology line. Its essence is that one battery is suitable for a whole set of tools. If you have a battery tool of this brand, puzzle over how to choose battery screwdrivers, you no longer need. Choose any tool in this line. Ryobi R18PDBL.Ll99s battery drill, for example, has a shock function. The browned model is complete with two batteries for 1.5 and 4 a/h, which will provide long.Term work. Two.Speed gearbox will make it possible to choose the desired speed for working with different materials. For a quick change of nozzles, a fast.Packed cartridge and a comfortable niche for fixing bit are provided.

Screwdrivers Bosch They are divided into professional (with a blue building) and household (in a green building). The former are distinguished by a large set of functions and serious working characteristics. And among households you can find the most compact models. Bosch IXO V Basic is one of the smallest battery tools in the ruler. Its weight is only 300 g, and the dimensions are such that the tool can be transferred directly in the In this case, the battery capacity is 1.5 a/h, the voltage is 3.6 V, and the torque is 4.5 nm. There is an indicator of the battery charge, built.In backlight, reverse and automatic spindle blocking. In a word, high.Quality household tools.

Battering drills-shuruvrets Bison. A great solution when you need to purchase a good tool, but I do not want to overpay for the brand. Among the technique of this domestic brand, you can choose a shock and multi.Speed option, while fitting from 2000 to 7000 rubles in the budget. Ben-shuruvrebruster Zda-10 battery.8-L-K-one of the popular models for household work and a small workshop. Two speeds, reverse, fast.Packed cartridge make this tool a reliable assistant to a practical owner. The model has the functions of the engine brake and the start of the start.Up and 12 options for limiting the torque, the maximum indicator of which reaches 32 nm. And what is no less valuable. The equipment that includes the charger, the set of bit and drills, the case for storing and transporting the tool.

Types of screwdrivers on connection

According to the current source, screwdrivers are divided into:

– receive energy from rechargeable batteries. Their main advantage is mobility. You are not attached to the outlet, you can calmly move around the workshop, crawl into the most inaccessible places without extension cords and wires. It is convenient to take the battery screwdriver with you to the country, to the village and to where you can not connect to the electric network. Often in the kit, a replaced battery is in the kit for the screwdriver, which can be charged in advance. Significant minus. Trying to extend the operating time of the screwdriver on batteries, manufacturers make models of lower power. Battery in screwdrivers can be several types. Nickel-cadmium is an outdated type of battery, in many countries that have already become out of use due to the components harmful to the environment. Have a relatively low power and are subject to memory effect. If such a battery is not completely discharged before charging, then in the future the maximum capacity of the funded battery is reduced. The nickel-cadmium battery needs special care. It is recommended to store the tool almost completely discharged, periodically you need to completely charge and discharge the battery. Experience 1000 charge-discharge cycles. Their only plus is low price. Therefore, such batteries can only be found in the most budget models. Suitable if you do not plan to use a screwdriver too often. Lithium-ion-the most common type of battery to date. Accumulate a lot of charge, preserve it well, have no memory effect. Usually these are the most durable batteries-they withstand several thousands of charge-discharge cycles, do not require special care. The only negative is unstable work in low temperatures. If there is a choice, it is worth buying a screwdriver with a lithium-ion battery. Nickel-metall-hydride batteries work steadily even at very low temperatures. Therefore, such batteries are installed in a technique that will be operated in the cold. Among the negative sides. The same effect of memory (albeit not so pronounced) and a high degree of wear (after 500 charge cycles, you need to replace the battery with a new one).
– connect to the electric network. As a rule, network screwdrivers are more powerful, because you can not worry about the quick battery consumption. The obvious drawback is the presence of a wire and the need to use the extension cord, which is not very convenient when used on the street or in the conditions of repair in the apartment.

Power supply from the network, type of cartridge fast.Sounding, torque 36 nm, max. Rotation speed of 1500 rpm, illumination of the working area, weight 1.4 kg.

Brief certificate how to choose a screwdriver

The screwdrivers are currently presented in several main types, so before choosing, we will get acquainted with the advantages and disadvantages of each type of screwdriver.

So, in the line of screwdrivers, such types of tools are represented that are perfect for operation at home and in work:

• The usual screwdriver is a manual tool with a fist cartridge. They will be drilled and work with fasteners. He has a clutch that regulates the torque. Has from 1 to 3 rotation modes. Sometimes there is a shock function, but there is no tangential blow. You can choose an electric (network, battery) or pneumatic drive. There is a wheelbase with a landing cone for a drill to replace the cartridge.
• A screwdriver with the possibility of adjusting the screwing depth is popularly called a screwdriver for GKL sheets. This manual screwdriver has only 1 speed. There is no cam cartridge compared to the aforementioned model. To drill a drywall sheet, you need to use drill with a hexagonal shank. Sometimes supplied with a self.Tapping screw. Can be selected in electrical network or battery options.
• A screwdriver with a battery is presented in the form of a compact manual tool with low power, there is a spindle lock. It is designed for manual dispensing or twisting. It is produced with a hexagonal mount of a screwdriver with a change of tip for one quarter and without a mechanical cartridge. If you need to drill holes, it is necessary to purchase a drill with a hexagonal shank. Manufacturers sometimes produce it with a coupling that regulates the torque, but without a coupling that regulates the depth of screwing. You can choose only one speed. You can also choose screwdrivers on electricity with the ability to work on batteries and batteries.
• Gaikovert twists and unscrews bolts and nuts. It is produced in manual version and in the form of heavy equipment on a wheel platform or placed on the suspension. The impulse operating mode is inherent. There is no fist cartridge, it is replaced with a short square rod, the dimensions of which are indicated in inches. This tool is used only at the same speed. Not equipped with a coupling that regulates the torque, or a coupling that regulates the depth of screwing. To limit torque, you will need to purchase torsion. You can choose electric (network or battery), pneumatic, hydraulic or gasoline drives.
• The screwwoman is the same manual tool as the Gaikovert, but its purpose in working with screws and self.Tapping screws. Another difference is also the presence of a hexagonal holder. Manufacturers have expanded their assortment of this model with a combined solution in combination of an external inch square per second and internal hexagonal holder per fourth in the landing part of the spindle. In case of preference of this model, it must be taken into account that it works on drills with a hexagonal shank. You can choose electrical and pneumatic drives.

According to the main characteristics, screwdrivers can be selected by:

• Energy source. Power is used from the network or autonomous power. If there is the possibility of using a socket and there are no restrictions on the length of the power cable, then an electric tool is preferable and cheaper. In order to understand what kind of electric screwdriver is needed, you should know that its indicators are measured by power consumed or output power. However, it should be noted that the tool with autonomous nutrition is safer. When choosing batteries for a screw version, you should know the following parameters:
• Voltage (it should be from 4 to 35 volts, and for the battery it should be from 11 to 19 volts);
• The time of action of one battery with a container of 1.4 to 7 amperes;
• The type of battery should be ion lithium, cadmium nickel or nickel metal hybrid species.

The positive properties of a screwdriver include adaptability, autonomy, and current safety. Negative properties include limitations in the number of hours of work and frequent loading.

• Twisting to the moment. This parameter determines what kind of display and length the screws will be fastened and which hole can be made in a tree, steel or concrete surface. It should be noted that there are soft, hard and long types of torque.
• Adjustment of the torque, preventing a threaded breakdown, grinding a slot and wear of a change of head.
• The maximum number of idle speed. This characteristic and all the following are the additional properties of this tool. Nevertheless, knowledge of this particular parameter is very important when choosing a device. It is known that each tool has its own individual boundaries of future drilling, which depend on the maximum drilling diameter. The value of the created hole in the selected material depends on the size of the drilling diameter. The type of drill and the power of the device affects the size of the drilling diameter. Due to the resistance of the drill, as well as the high speed of rotation of the component and the friction between them, the drill heating occurs, which may burst. If the drill and processed material are incorrectly selected, then this is fraught with the occurrence of burrs and deformation of the preform. For metal, the size of the drilling diameter is in the range from 5.5 to 23.5 mm, along the wood. From 9 to 51 mm. Typically, work with wood is the most common task.

TOP-10 of the most powerful screwdrivers

Network and battery screwdrivers differ not only in power sources. Cost, functionality is understandable. But there are parameters that divide them into household and professional. We will tell you what the most powerful screwdriver should be and how to determine the power of the screwdriver in a particular type of tool.

Professional or household?

The first question that arises if it is necessary to choose a technique almost always concerns its class. With professionals who specialize in repair work, everything is clear: they need a universal tool of high power, with a good battery capacity, a large number of settings, the most complete configuration. It is more difficult with household appliances, because it is important to choose a model called “for all occasions”, without excesses, for which you will inevitably have to pay when buying, but at the same time with a sufficient set of opportunities that will always be useful during the next repair.

It is important to initially decide on what kind of surfaces you will have to work, because, for example, when working with solid materials for effective work, the speed of rotation should be higher than 1200 rpm, while household models make it possible to work with a maximum of 400 speeds. As for the drilling function, the torque of the household tool is within 15-20 nm, while in professional models it is an average of 130 nm, which means that it can easily work with materials of any hardness.

In addition, professional and domestic models are characterized by operating voltage: the higher it is, the more complex tasks will be capable of performing a screwdriver. For comparison: household models most often use 9.6 V, and professional from 12 V and above.

Engines in screwdrivers

In modern screwdrivers, two types of engines are used:

Brush (collector) engines are the heirs of old technologies. To supply current to the engine from the battery, special contacts are used, which are called brushes. Over time, such brushes wear out, so sooner or later there will be a need to replace them. It’s good if the screwdriver provides for a fast contact replacement function. Otherwise you will have to disassemble the device almost completely.

Brightless (contactless) screwdrivers Compared to their predecessors, they have much larger efficiency during work. The current is supplied to the engine using electronics. There are no elements that would be carried out by Rapid wear, so most manufacturers smoothly switch to this type of engine.

Short.Term loads are well tolerated, there is no electrical sparking from brushes, which allows you to work in rooms where explosive gas mixtures can be located. The minus of these devices is one. Price. However, in the long run, a screwdriver with a bronnial engine pays off with more than.

Network or battery

Depending on the method of obtaining food, all screwdrivers are divided into network and battery. The first option receives power supply to the network cord, they are much more effective due to constant power and due to the lack of need to monitor the value of the charge. But, in comparison with battery screws, they cannot be used in places where there is no 220 V electric network, they also have a fairly large weight. A separate disadvantage of network screwdrivers is nutrition from a dangerous voltage level, while batteries, feed on low voltage and do not threaten the working in the event of breakdowns.

Battery screwdrivers are mobility. They can be used in places where there is no power supply at all or where to carry a bulky tool is inappropriate. Such models differ relatively small weight and dimensions, but they are more expensive and can be discharged at the most inopportune moment. The main parameter to pay attention to, when choosing a battery screwdriver is the type of its battery and its capacity.

Types of batteries

Types of batteries determine the most important parameters. The duration of the screwdriver, the need for a complete discharge, the duration of the charge, the service life and the price of the electric tool itself. Today there are four types of batteries:

• Lithium-ion, It is indicated as Li-Ion Battery-relative to others holds the charge for a long time, also quickly accumulates it and does not require complete discharge. To date, this is the most effective option for construction and electrical operations, its main disadvantage is the high cost, so for single work screwdrivers with such a battery is better not to choose.
• Lithium-polymer, It is indicated as Li-Pol Battery-has the largest capacity among batteries for screwdrivers, but it fails faster than others.
• Nickel-cadmium, The batteries are designated as Ni-CD-they differ in the highest life, about 5 years, in comparison in others about 3 years. This option is also characterized by low cost. The disadvantages include a long charge and the need for a complete category.
• Nickel-metallogid, They are designated as Ni-MH batteries are characterized by a good battery capacity, unlike other models, have much less weight with the same battery capacity. Due to what such a battery screwdriver has smaller sizes, but also much more cost.

For home use, it is better to use nickel-cadmium models, due to rare use, their long charge is not so critical, and a long period of operation will allow you to forget about the replacement for a long time. For professional activities, lithium-ion and nickel-metallological screwdrivers are well suited.

How to choose a screwdriver for the home by characteristics

Network screwdrivers are selected by power, according to the type of cartridge and in speed of rotation of the nozzle. In the first case, it is necessary to select models with a minimum power of 600 watts, as indicated above.

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

In the list of characteristics there is a paragraph about the type of cartridge. Today, rapidly and hexagonal cartridges are distinguished today. The first option is more practical in everyday use, since a separate hexagonal key is not required to replace the nozzle. One.Button or two.Button cartridge is tightened manually. The first option requires less effort. This design is more often installed on expensive screwdrivers.

The hexagonal cartridge requires a clip of bit by a separate key, which is included in the device. Additionally, such screwdrivers are always equipped with bits with a different tip that can be changed with one hand, and then tighten the connector with a small key.

When choosing, it is important to pay attention to the total weight of the tool. Models with the battery weigh 0.5-1 kilograms of more network options, which can lead to inconvenience during prolonged work. If the screwdriver weighs up to two kilograms, this will reduce the accuracy of its application and accelerate the onset of the physical fatigue of the operator.

Few notice such a detail as the location of the handle. Some power tool models have a standard “pistol” form, while in others the hilt is shifted to the center for stabilizing 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.

Which battery for a screwdriver is the best

List of nutrition elements for a small screwdriver. All of them deserve attention, but you need to choose here based on their preferences.

Types of batteries

• Li-Ion (lithium-ionic). Low degree of discharge, no “memory effect”. Inexpensive, suitable for all areas of activity.
• Ni-CD (nickel-cadmium). Are more expensive, there is a weakly expressed “memory effect”.
• Ni-mh (Nickel-metallogid). The most expensive, you can work at low temperatures.

What criteria to pay attention to when choosing a screwdriver?

If you are wondering what kind of battery screwdriver to choose, then you should pay attention to the main characteristics and additional functions, because they can come in handy in one or another work.

Design

The battery can have the following design:

• Pistol. The standard perpendicular location of the handle with respect to the body. It is convenient to keep pistol type devices and crush during drilling/unscrewing. If you do not often have to work in constrained conditions, then a pistol screw your option is your option. We also note that the units of this type are more powerful than the angular “shuriks”.
• Corner. In these models, the cartridge is located at an angle, so you can climb into hard-to-reach places, for example, when you need to screw screws somewhere under the ceiling. Also, corner devices are very convenient when assembling furniture. However, if you are engaged in serial assembly of furniture, then most likely you will have enough pistol device.

We also note that there are so.Called adjustable models in which the cartridge can rotate at different angles. However, they are more expensive than corner and pistol devices and at the same time less powerful. For the house they are not very relevant, and often the usual pistol model fully satisfies the need. But by what other parameters to choose a battery screwdriver for the house?

Torque

Twisting (km) is an effort with which the device screws the self.Tapping screw. The larger the moment, the easier the fastener element will be included in solid material. Pay attention to the torque in the screwdrivers, which is divided into three groups:

For work exclusively with drywall, devices with a small torque are quite suitable. To assemble furniture, it is better to take a device in which the torque will be in the range of 30. 70 nm. But if you need to constantly work with solid materials, then you will definitely need an unit with a large torque.

Shock or unstressed “Shurik”?

Shock screwdriver is not the same as the shock drill. Here the blows are obtained in the form of impulses that rotate the nozzle with some jerks. In fact, the shock mode is designed to screw large fasteners into high density material. The stress mode also helps to drill small holes in concrete.

Shock models, all other things being equal, can cost much more unstressed devices. Therefore, if you do not plan to drill brick or twist long self.Tapping screws into Canadian maple (in fifth place in hardness of wood in the world), then an unstressed model will suit you.

Functions and possibilities of screwdrivers

How to choose the right screwdriver for additional functions? It all depends on the type of work performed. Here are the most popular functions that the high.Quality screwdriver for the home should have:

• Reverse. A function designed to remove fasteners. It would seem that absolutely all “shuriks” should have this function. However, we noticed that some “Nounim” Chinese devices only allow you to tighten the bolt, but not to unscrew. Pay attention to this when buying.
• Backlight. The backlight improves the review of the screwed fasteners (or holes). The function is especially convenient when working in unlit (or with poor lighting) room and in hard.To.Reach places.
• Adjustment of torque. One of the most useful functions of Shurik, as it allows you to configure the power of rotation for a certain material. For example, for screwing fasteners into a solid wood, it is better to increase the torque, and when unscrewing rusty bolts, it is better to reduce so as not to disrupt the slot. If you are engaged in the repair of household appliances and you often have to work with old fasteners, then you definitely need an unit with the adjustment of the CM.
• Speed ​​adjustment. If the torque can be changed in 20. 25 positions, then the speeds in the device can be 2. 3 maximum. For screwdrivers, speed adjustment is relevant when drilling different materials. For example, high speeds are suitable for soft materials, and for hard.Firmly low. However, if you need to drill often, then we advise you to take a closer look at the reliable network drums.
• Blocking button on. This constructive element in screwdrivers is often intended for drilling. If you drill several holes in a row in the workpiece, then it is convenient to press this button so as not to constantly keep the starting key key. These button are usually equipped with heavy powerful devices, which are supposed to be frequent drilling holes. If you already have a drill at home, then you do not need such a “shurik”.
• Engine brake. After the power is turned off, the engine can rotate the cartridge for some time. This function almost immediately disconnects the engine so that you do not have to keep the device on weight, waiting for the arrangement of the cartridge.
• Engine protection. Protection turns off the engine when overheating (in screwdrivers occurs extremely rarely) or when jamming the drill in the hole.
• Brighting engine. In comparison with collector engines, the brilliant ones give out a higher efficiency and at the same time do not spark. Typical engines are usually equipped with powerful devices with a high torque moment. But of course they have a rather big cost.

And with which battery to choose a screwdriver? It is not necessary to explain for a long time-with lithium-ionic. It is deprived of the “memory effect”, has a good container (depending on the model) and more durable than nickel-cadmium. It is worth noting that 99 % of screwdrivers are equipped with lithium-ion batteries now.

How to choose a screwdriver

Screwdrivers are constructively very close to drones. Sometimes manufacturers even create both devices on the same base. No wonder they are often called “Battery Drill Shurovret”. In other words, one can do with one drill with an adapter for bit in the household. But is it necessary? Let’s talk about this class of the power tool with seller-consultant of the construction equipment store Anatoly Gopkin.

Wire or battery

Wended screwdrivers in the early 1920s are less and less found on sale. The reason for the victory of the battery devices is simple. Although they are more expensive, but much more universal in use. Scurrys working from the network often choose, for example, to work in a car service. But for home and repair, the battery is simply indispensable. The upper class is charging that can completely replenish the energy supply of less than an hour.

Torque

Almost the main characteristic for the best screwdriver for the home is the torque that develops its electric motor. This indicator speaks of the rotational action of force on the solid body. In other words, the more torque, the easier the tool copes with the twisting of screws or screws. Even in complex materials such as concrete or metal.

Ergonomics

Imagine. You need to tighten more than a hundred self.Tapping screws into the roof of a summer house. In such a situation, the screwdriver should be convenient to operate, otherwise difficult work will turn into hard labor. This is why ergonomics are needed. Firstly, this is a mass. Less is better. This also includes the amusing, which should reach 50:50 in the best screwdrivers for the house. Secondly, the convenience of grip and body size. Too small models are bad in hand. Finally, the amenities add trifles such as a latch for waist mounting or additional bit holders.

Functional

The screwdriver is not as simple as an electric screwdriver. And different models, depending on the level of performance, have many options. Reverse, which a screwdriver is even more needed than a drill, in almost every model. It is much easier to twist the bolts with it. Often there is also illumination of the working area. But in some, even expensive models, it is made so stupid that when working with large screws, it becomes useless. The brake of the engine, which instantly stops the operation, is very helpful, you just need to release the button. In professional models there is a thin adjustment of torque, which allows you to adjust the tightness force. It will not be superfluous and the indication of the remaining charge on the battery.
