This article will discuss the types of screwdrivers for furniture assembly, their main characteristics and features.
The modern construction market offers the client a huge selection of construction equipment, including screwdrivers. Which screwdriver should you choose if you are purchasing it for furniture assembly?
Company manufacturer
The construction tools market is diverse. Each company tries to show its product from its advantageous side. But there are models that have long won the trust of buyers.
Metabo
The German brand Metabo supplies construction and other equipment to more than 100 countries. The company's cordless and electric screwdrivers have a long service life, are reliable and easy to use. The range of tools offered includes both cheap and premium models.
Makita
A Japanese concern producing power tools. Makita screwdrivers occupy a worthy place in the domestic market. The brand produces more than 1000 models of construction tools. All products have a certificate. All stages of production undergo strict control.
Interskol
A domestic company that occupies not the last place in the production of construction and garden equipment. Over the 25 years of its existence, the company has shown itself only from the best side. New technologies, the use of original components and affordable prices for screwdrivers are the calling card of Interskol.
Which is better - Makita, Bosch or Metabo?
All of the listed brands have long earned the trust of users, because their products are distinguished by excellent build quality, ease of use and advanced functionality. But it is Makita screwdrivers that are considered the best in terms of price and quality ratio.
Metabo and Bosch devices are more expensive, but by choosing the right Makita screwdriver model, the user will be able to perform a lot of work without spending a significant amount of money on the purchase of a power tool.
Features of choice
When choosing power, you should take into account not only what power of the screwdriver is indicated in the information from the manufacturer. Due to too high performance, the device may tighten the screws too tightly, pressing their head into the surface
As a result, the appearance of the coating deteriorates, and the fasteners, if necessary, are almost impossible to unscrew.
Choosing what voltage
better for a screwdriver, it should be borne in mind that voltage is the main parameter of the device. For example, the power of the Makita DDF343SHE motor screwdriver is 700 W, with a voltage of 14.4 V and a battery capacity of 1300 mAh and a torque of 36 Nm. Whereas the other model Hammer ACD182 has a weaker engine (22 Nm) and a less capacious battery (1200 mAh) - and it seems that this device is about 40% weaker. However, due to the 18 V voltage, the Hummer is able to tighten more fasteners without recharging, even being inferior to its competitor in terms of battery capacity. You can understand why a screwdriver that seems less productive at first glance is inferior to a more powerful one by doing a little calculation:
- the amount of energy stored by the first model is 1.2 x 1.8 = 21.6 Wh;
- the second indicator is only 1.3 x 14.4 = 18.72 Wh, i.e. 15.4% less.
When choosing a screwdriver, it is advisable to take into account the presence of a spare battery included with it. Some models even have 2 additional batteries. On the one hand, such equipment will cost more (especially since the cost of the battery is up to 80% of the price of the equipment), but it will be much more convenient to work with it. At the same time, an additional battery is not needed to perform household tasks - the time of work performed with its help rarely exceeds 1–2 hours. While in the process of constant use of a screwdriver (for example, for repair work or furniture assembly), the second battery allows you to not interrupt the work for longer than a few minutes. The discharged battery is charged, and a spare battery is installed in the device.
If there is no need for long-term work, which may require a screwdriver, it is not recommended to buy a model with additional batteries, not only because of its increased cost. It’s just that the service life of such a battery is short, and after a couple of years the user will have to buy a new part without using up even half of the life of the old one.
Basic parameters of the battery and the tool itself
The main parameter that characterizes the operation of a screwdriver is the battery voltage, which, in turn, determines the power of the electric motor and torque . For household models, the difference in voltage between screwdrivers is small - on average, it is in the range of 10.8–14.4 V. More productive options intended for constant use can be equipped with 24–36 volt batteries.
The battery voltage of a screwdriver also depends on the type of battery - you can answer what the difference is by knowing what metals were used to make it. For nickel-cadmium batteries, large in size with a similar capacity, the value of the indicator is a multiple of 1.2 V (this is exactly the voltage of one element that makes up the battery pack), for lithium-ion batteries - 3.6 V.
Other equally important characteristics include:
- torque, the value of which can be one of the main answers to the question of what the voltage of the screwdriver battery affects. Using this characteristic, you can determine both the diameter and the length of the screw or self-tapping screw being screwed. Large fasteners, as well as drilling deep and wide holes and hard materials, require significant torque. Torque – 12-15 Nm (maximum up to 30 Nm) is enough for home models, and from 30 Nm for professional models. This parameter is important, pay attention to it.
- If the maximum speed is below 1000 rpm, the tool will be convenient for tightening screws and drilling soft materials (wood, metal, plastic). If you are going to drill metal, choose models with speeds above 1500 rpm. They will have two speeds: the first is for fastening, the second is for drilling.
- For serial work (installation of drywall sheets, clapboard paneling), choose corded screwdrivers with a depth limiter. Both mains-powered and battery-powered models are suitable for working at home, so choose what you like best.
There are two types of torque for screwdrivers - starting (larger in magnitude and required to put the device into operation) and constant, that is, working. The parameter value for modern equipment models can be adjusted - you can find out how many modes can be selected for a particular device in the documentation available for it. Moreover, tools with a pulse mode of operation (turning on the rotating part in jerks) have more screwing capabilities - allowing them to periodically increase the torque, they can screw in a larger screw.
The output torque value of electric motors is not constant and depends, first of all, on the speed of the motor; the higher the speed, the lower the torque on the shaft.
In addition to the voltage of the screwdriver and its power, the battery capacity should also be assessed. The characteristic is measured in ampere-hours or milliamp-hours. The higher the indicator, the longer the screwdriver can work without recharging.
The average battery capacity of a household model is 1300 mAh, which is enough for 2–3 hours of operation. Professional equipment requires more time to complete the work - and a master who uses a screwdriver throughout the whole working day should purchase a model with a battery of 1.5–2.0 Ah or more.
The best corded screwdrivers
Wired models are not as convenient as their cable can sometimes get in the way during operation. In addition, the need to connect to an outlet does not allow, if necessary, to immediately move from the garage to the bedroom, and from there to the kitchen in order to tighten several screws everywhere. You always have to first disconnect the device, and then collect the wire and reconnect the screwdriver in another room.
But on the other hand, owners of networked models do not have to wait a long time for batteries to charge when they have to work for a long time, and in the process they will not be left without a tool due to a dead battery. Also, wired solutions tend to have higher power and rotation speed
Due to the absence of batteries, such screwdrivers weigh less, which is important if you need to hold the device in your hands for a long time
DeWALT DW274K
Are you looking for a good corded screwdriver for simple home use? We recommend choosing the DeWALT DW274K with a power of 540 W. It is equipped with a suitcase and a head that is set to the screwing depth. The device also comes with a holder for attachments and a clip for attaching a screwdriver to a belt.

Advantages:
- belt clip;
- idle speed;
- high-quality case included;
- optimal weight for long work;
- Excellent assembly and reliable design.
Recommendations.
Let's consider two characteristics of the product - professional and household for home use. What's the difference? First of all, it is a load; If you are a furniture assembler and use a tool every day, then you will need a professional one. At home for household needs - a cheaper analogue. When purchasing, pay attention to the year of manufacture (the older, the worse), inquire about the storage location of the product (in normal temperature conditions), the durability and quality of the screwdriver depends on this. From recommendations from my own experience
AEG- 12x best NiCd – 2.5 years without interruption, rating 5 Milwaukee PLD 12 X NiCd – 2.5 years, in the third month the charger burned out, rating 4 Makita BDF343 Li-Ion – in operation for more than two years (replacement of gearbox and engine) rating 4+ There were bosch, black decker, sparky, and others - in operation for less than a year.

General rules
There are a number of rules that extend the life of any battery when forced to send it for long-term storage:
- When using a power source with a long break, it is necessary to carry out a complete discharge-charge cycle of the element several times;
- The ambient temperature in the warehouse should not fall below 10 degrees Celsius;
- Extending the service life of a battery at rest is facilitated by periodic charging and complete discharging of the current source - at least once every six months;
- If the power tool is not going to be used in the near future, the battery must be disconnected from it and cleaned of all visible dirt.
Storing Nickel-Cadmium Batteries
If you do not use power tools regularly, it is wiser to store nickel-cadmium (NiCd) batteries in a discharged state. These elements have a specific property - a high level of self-discharge. Therefore, during storage, a fully charged battery will discharge on its own over time: every month the remaining charge level will decrease by 8-10%.

Following simple recommendations for long-term storage of nickel-cadmium cells without use will allow you to obtain a fully operational current source after a full charge. The basic rules are:
- 3-4 full charging cycles followed by discharging the element;
- The temperature in the storage room is not lower than 10 degrees Celsius.
Storing lithium-ion batteries
Lithium-ion (Li-ion) power sources are sensitive to temperature conditions and residual charge when sent for long-term storage. The available charge level when starting use directly depends on this.
For lithium screwdriver batteries, adhere to the following rules:
- Eliminates the possibility of freezing - when using a refrigerator as a storage space, place it in the main compartment and not in the freezer;
- The optimal temperature ranges from 1 to 25 degrees Celsius;
- Before sending for storage, the discharged element is recharged to a level of 40%, this will allow the charge to be fully restored if it is necessary to use a screwdriver.
The mobility of a battery-powered screwdriver has one drawback - they run out. Following recommendations for storing batteries increases their service life without loss of functionality. In this case, be sure to take into account the type of battery used in the screwdriver. Nickel-cadmium cells require complete discharge, and lithium-ion batteries will only be damaged by this procedure.
Hi all! People often ask on the Internet how to store screwdriver batteries correctly so that they do not fail prematurely. In this article I will try to answer the question posed.
At one time, I also asked myself this question and one wonderful thought came to my mind: “Why not look in the operating instructions for a screwdriver?” With this “brilliant” thought, I took the instructions from Makita and... found only general words in it
Well, this is about the fact that you need to store it in such a way that the battery contacts cannot be accidentally closed with a paper clip, coin or other metal object, that storage should be in conditions where the air temperature does not exceed 50 degrees, and so on, which is also of course important , but it seems clear
And everyone is interested in questions like these:
- At what charge level should batteries be stored?
- Do they both need to be removed from the screwdriver or can one be left inserted?
- How long can it be stored without recharging?

In the end, after reviewing the instructions from different manufacturers, I was able to find some useful information. Moreover, even if you look at the instructions for different screwdrivers from the same manufacturer, but differing in the type of battery, it will be the same. At the same time, if the manufacturer believes that it is necessary to indicate some special information for certain types of batteries, then it is indicated, but in general, the conditions are basically the same for all types.
Here, for example, is what AEG writes:
Here's information from DeWalt:
Or Makita gives universal advice for all types of batteries: recharge the batteries every six months of storage if they have been lying idle for so long.
In general, what can we say based on the information provided by the manufacturers? Let's go in order.
Which battery is better: lithium or nickel-cadmium?
This question about which battery is best for a screwdriver is not posed entirely correctly. It all depends on the situation and the length of time the tool will be used.
types of batteries
The diversity of rechargeable batteries is due to the fact that various chemical elements can be used as electrodes and electrolytes. The quality of operation of the power tool used depends on the correct choice of energy storage device. The following 3 types are most widespread in the field of electrical appliances:
- nickel-cadmium (Ni-Cd);
- nickel metal hydride (Ni-MH);
- lithium-ion (Li-Ion); lithium polymer (Li-Pol).
A lithium battery pack weighs less with the same capacity as cadmium. But this is not the main indicator on the basis of which you should choose a battery for a screwdriver.
Of course, the number of charge-discharge cycles for cadmium cells is several times less than for lithium cells. The standard for Ni-Cd is 500 and for Li it is 1500, which certainly initially makes one think that lithium batteries are much better and lighter in weight.
When choosing batteries, it is important to take into account the fact that the aging of nickel-cadmium batteries depends solely on the cycles they operate, and not on their actual age!
The service life of lithium-ion batteries, unlike cadmium, directly depends on age over the years. After 3 years they will already fail, even if they have not been used.
Nickel-cadmium batteries, on the other hand, will last a long time even if they are rarely used.
For example, when buying a used screwdriver, you should not take it with lithium batteries. There is a high probability that if the tool has not been used for a long time, or has been frozen frequently, its battery pack is no longer suitable for use.
If a used Shurik is sold with cadmium batteries, they can retain up to 60% of the charge, regardless of whether the tool was used or not.
If the screwdriver is not used very often, lithium batteries are more likely to “grow old” than to serve their required 1500 cycles. Therefore, for periodic household use there is no point in buying a tool with lithium batteries.
Cadmium can last 3 to 5 years, whether batteries are used or not. It can also easily lie in a warehouse, maintaining its properties, unlike lithium. If you do not plan to use a screwdriver often, the answer to the question of how to choose a battery will be short and truthful: choose cadmium.
By the way, in temperatures down to -20°C, cadmium “behaves” better than lithium batteries, which do not like extreme frosts. Lithium must be stored at least 60% charged. They need constant recharging when not in use. Otherwise, they begin to collapse.
Thus, it becomes clear that nickel-cadmium batteries are, in fact, no worse than lithium batteries. The main question is only the scope of application of both types of chemical batteries.
When used at the right time and in the right place, both can be equally useful and good.
Ni-MH batteries
Nickel-metal hydride batteries are less common than nickel-cadmium batteries for screwdrivers.
Their advantages include the absence of toxic components, environmentally friendly production, a slight “memory effect” and lower self-discharge than nickel-cadmium batteries.
In addition, when compared with Ni-Cd batteries, nickel-metal hydride batteries have a larger capacity and can withstand a greater number of charge-discharge cycles.
Ni-MH battery has the following advantages:
- they have virtually no memory effect;
- no toxic components are used in their production;
- ease of disposal; capacity is 30% greater than that of nickel-cadmium; light and compact; are not afraid of mechanical damage.
Minuses:
- takes a long time to charge; 500-600 charge-discharge cycles;
- after 300 cycles, a decrease in capacity can be observed;
- cannot be used at sub-zero temperatures;
- cannot be completely discharged; higher cost compared to the previous type.
Store nickel-metal hydride batteries half-charged and in a cool place.
Lithium-ion (Li ion). The most modern batteries
When thinking about how to choose a cordless screwdriver, we note that the most modern lithium-ion batteries also have their pros and cons.
Let's list their advantages:
- low weight and size;
- the specific capacity is two times higher than that of Ni-Cd;
- no memory effect;
- a large number of charge-discharge cycles (up to 700);
- low self-discharge: (3-6% per month);
- ease of maintenance (do not require strict adherence to charge and discharge modes);
- fast charging (on average 30-40 minutes).
A very popular model of the Metabo screwdriver, especially among furniture assemblers.
Thanks to the use of Lithium-ion (Li ion) batteries at 2Am. The screwdriver has become compact and lightweight. They also have disadvantages and they are quite serious:
- Do not work at sub-zero temperatures;
- Not restored;
- Low life expectancy (maximum 2 years). Moreover, the age of the battery is not counted from the moment of use, but from the date of its production (therefore, buy only “fresh” ones).
- Explosion and fire hazards;
- A complete discharge disables the battery (an attempt to recharge it may lead to an explosion);
- Sensitivity to overheating and shock;
- High price.
Another important point to remember is storing the cordless screwdriver. Nickel-cadmium batteries can be stored when discharged. Nickel metal hydride batteries, on the contrary, must be fully charged before long-term storage (several months).
A separate thing needs to be said about lithium-ion batteries: they don’t care whether you store them charged or discharged. However, remember that they get old quite quickly. Therefore, buy a tool with such power sources not for one-time work, but for intensive use. After just 1 year, a lithium battery will lose about 30% of its original capacity, and after 2 years the battery will have to be thrown away.
Makita DF333DWYE
Next in our TOP is Makita DF333DWYE. This is a compact cordless screwdriver that can be used when assembling furniture, performing repair and finishing work in buildings and outdoors. It copes well with small fasteners, and also allows you to drill holes with a diameter of up to 10 mm in metal and up to 21 mm in wood. This screwdriver has 2 operating speeds and 18 torque settings with a maximum value of 30 Nm, which allow you to select the optimal parameters for working with various materials. And the quick-release chuck provided in it will ensure reliable fixation and change of bits and drills. Among the features of this screwdriver, it is worth noting the battery protection against overload, an electric engine brake, a clip for wearing on a belt, as well as a bright backlight, which is useful when working at night on the street and in poorly lit rooms. The backlight goes out approximately 10 seconds after pressing the button. So you don't have to constantly keep your finger on the switch. This screwdriver weighs a little more than a kilogram, but this is without a battery. In this regard, the manufacturer provides customers with a choice and allows them to connect branded 12-volt batteries with a capacity of 1.5 to 4 Ah to such a screwdriver. However, even with the heaviest battery, the weight of the tool will not change much. So it will be convenient to work with it, and you will not get tired of holding it for a long time.

What is a screwdriver
A screwdriver is an electric tool, the main purpose of which is to carry out work on screwing in or unscrewing various screws, bolts and self-tapping screws. One can only imagine how time-consuming it would be to screw in several hundred screws by hand when assembling, for example, a typical built-in cabinet or tool rack. Using this device, the entire job will take just a few minutes. In addition, this power tool has some other additional features:
- use as a cordless drill;
- replacement of conventional hex keys using special attachments;
- backlight function in low visibility conditions.
An electric screwdriver is also convenient because it can screw screws to a given depth. Therefore, all screw heads will be located in the same plane, which will give the work a beautiful and finished look.
Battery device
When talking about batteries, it is also important to consider how it is built from the inside. All production models are placed in a plastic case, where batteries are located connected by a contact tape.
The end of the tape, as a rule, is brought out in the form of contact plates. Inside there are cylindrical batteries, which come with 8, 10 and 15 batteries - depending on the model. They are tied with nickel tape, taking into account the correct sequence.
Depending on the manufacturer, the housing can be either collapsible or non-demountable. The only difference between them is that in the first option no additional intervention is required.
What is the difference between the tools
An impact wrench is generally considered a tool for professionals, while a screwdriver is mainly used for smaller household jobs. The main differences between a wrench and a screwdriver are their following characteristics.
- An impact wrench is more bulky than a screwdriver and does not have a chuck. At the end there is a special rod on which a nut head is attached.
- The power of a wrench applied to an object is many times greater than the power of a screwdriver. Using the first one, you can solve any “problems”.
- There is a significant difference in the weight and size of these mechanisms. Impact wrenches are usually larger and heavier.
- Screwdrivers have several operating modes that can be adjusted. Unlike them, no other special tools have this capability.
Thus, impact wrenches are used more often for heavy mechanical work, while its competitor is more often used for simpler household repairs. In addition, for simple tasks, you can try to make a wrench yourself using ordinary attachments.
Which tool is better to choose? The answer to this question will depend on the type of work where these tools will be needed. Considering that the impact wrench has a tangential impact during operation, it cannot be used for tightening screws, as it will simply tear off their heads. However, if you ensure that there is no stop, then it can make a fastening that even the most powerful screwdriver cannot create. If there is a small amount of work to be done, including only screwing in screws, then an ordinary screwdriver will be enough for this. Therefore, it is necessary to decide what to choose for the job - a screwdriver or a wrench, based on specific circumstances.

Top 10 best 12V screwdrivers
By food type
It is also customary to divide tools according to the type of food. We are talking about such classifications as battery and network devices. In the first case, a screwdriver is used for long-term work without interruptions. But keep in mind that they require access to a network, which is represented by a voltage of 220 V. Often, they are used for repeated repeated tightening of fasteners. For example, for sheets of drywall. Such devices are famous for their high rotation speeds, as well as for the multiple acceleration of installation work.
If we talk about the cordless screwdriver, then it is suitable for use in places with difficult to reach features. Those. in this case, a network device is simply not appropriate. But not everything is so smooth. This model has a minus. It is connected with the fact that you need to constantly charge the device. As charging declines, power decreases.

Characteristics of a drill and screwdriver for furniture assembly
In our article we will conduct a small analysis of the technical characteristics of modern cordless screwdrivers.
Currently, in most cases, furniture assembly is impossible without the use of specialized tools. To install furniture fittings, a drill-driver is used; the functionality of this tool is undeniable: practical, convenient and financially justified for professional work on furniture. It is also applicable for domestic purposes. The device allows us to perform screwing and unscrewing elements of furniture fittings and drilling in furniture. Some cordless drills/drivers are equipped with an impact mechanism for drilling in dense building structures for hanging or fastening furniture, such as concrete or brick, but do not forget about battery life and impact force. Article on the topic: Why do you dream about a new apartment without furniture?
The main factor in the tool is the battery, which is divided according to the type of internal chemical filling, voltage (power) and capacity (volume) of electricity. The most progressive lithium Li-ion, since the efficiency is higher, environmentally cleaner, weight is significantly less than Ni MH and Ni Cd. Voltage from 3.6 V to 36 V is the strength of the screwdriver, traditionally used from 9 V to 18 V. Typical battery capacity is from 0.9 A/h to 3.5 A/h. A large battery capacity is needed, for example, when assembling office furniture in large quantities, where a screwdriver is used 98% of the time from the entire tool set. It is worth paying attention to the battery charger, a fast charger (charging from 20 minutes to 1 hour) or a regular charger (from 4 to 8 hours). The drill-screwdriver is equipped with reverse (reverse movement), adjustment of the force and speed of the rotating torque.
Changing attachments
Changing the attachment on a screwdriver is not difficult. The tool can be equipped with a quick-release chuck or a key-type chuck. Replace the equipment in both cases in a similar way. To remove a drill from a screwdriver with a keyless chuck and insert a new one or another type of equipment, proceed as follows:
- first, select a bit according to the size of the head and the type of slot on it (cross, straight or other) or a drill of the required diameter corresponding to the material in which the hole is to be created;
- spin the cartridge counterclockwise;
- in the center, between the spread cams, install the selected type of equipment;
- Rotating the cartridge case in the direction of the clock hand, clamp the nozzle.
You can remove the drill bit from the screwdriver (or another attachment) by holding the moving part of the chuck with one hand and pressing the start button with the other. Just first switch the direction of rotation to unwinding.
When a drill-driver is equipped with a key chuck, then to change the equipment do this:
- inserting the key into the recess for it, unscrew the cartridge;
- I install the nozzle;
- clamp it by turning the key clockwise.
There are models in which you can remove one type of cartridge, for example, a quick-detachable one, and replace it with a turnkey analogue. When choosing any option, you need to focus not only on ease of use, but you should also consider the pros and cons of each of them
Thus, the key chuck securely clamps the equipment, which is important when drilling, and the quick-release chuck allows you to quickly replace it, even with one hand (the other holds the handle, pressing the start button as necessary)
What is the difference between a wrench and a screwdriver?
During work, difficult situations often arise when the use of just a wrench becomes clearly insufficient. Then you have to pick up special tools: they help in working with parts that have threads. Among them are a screwdriver and a wrench. These technical devices serve one purpose - to speed up work involving a large number of nuts, bolts and screws. At the same time, despite the similarity of the problems being solved, they also have a number of significant differences. You can learn about this and which tool is best to use from the review below.

A few words about the impact wrench
An industrial or homemade impact wrench is used to install and remove bolts and nuts. Some may accidentally confuse it with a drill, but experienced craftsmen will immediately point out the special attachment in the holder that a regular drill does not have. You definitely won’t be able to do without it if you need to unscrew an old nut that is so rusty that you simply can’t unscrew it with your hands or a wrench. The tool is available in the following versions:
- pneumatic;
- gasoline;
- hydraulic;
- powered by electricity.
The impact wrench is widely used in repair shops and for various assembly work. More powerful tools are used in mechanical engineering.
Criterias of choice
The construction tool is selected by the user based on his preferences
But there are some characteristics that are worth paying attention to first.
Types of batteries
Batteries for screwdrivers are available in three types:
- Nickel-cadmium batteries (Ni-Cd). Operation in low temperature conditions. They are stored for a long time and are unpretentious in work. You can work with cadmium cells until they are completely discharged - they are not afraid of a complete stop. The disadvantages here are the presence of a “memory effect” and high toxicity.
- Nickel-metal hydride batteries (Ni-Mh). Developed as an improved version of nickel. Small in weight and dimensions. Weak “memory effect”, large capacity, low toxicity. 1500 charge/discharge cycles. Disadvantages include rapid discharge, susceptibility to cold and short service life.
- Lithium-ion batteries (Li-Ion). Considered the most popular. There is no “memory effect”, you can charge in any condition, even at minus temperatures. No harmful substances, long service life, high power. Negative aspects are the high price tag and sensitivity to falls from heights.
Users are often interested in the question: what is the current in a 12V screwdriver and how to calculate it? There is no exact amount of current produced by the motor. Manufacturers do not bother themselves to indicate it on the box.
This figure is approximate and does not apply to all 12 volt screwdrivers. As a result of the research, it turned out that for a 12-volt tool, a current of 10 A is sufficient. In some cases, current drops can reach 30 A.
This leads to the question: which power supply is suitable for a 12V screwdriver? Here you can use a 12 volt unit of the same name with a current output of 10 A. If the amperes are in the range of 20-30, this is even better.
Brush or brushless
Depending on the model, the screwdriver is equipped with a brushed or brushless motor.
The main advantage of a brushless motor is the absence of sparks. You can work in areas where there is a high risk of explosion. The screwdriver produces the same speed in both directions.
Inverter motors are not afraid of overloads, are durable and have high efficiency. The disadvantage lies in the high cost of the tool. Therefore, it is better to choose such a screwdriver for professional work.
The brushed motor version is more widespread. Easy to assemble, compact and low price tag. There are more disadvantages. Rapid wear of brushes, low power, low efficiency. Sparks appear during operation. Because of this, there are limitations in operation.
Rotational speed
For home repairs and in everyday life, you can buy a screwdriver with a rotation speed of 350-450 rpm. This is enough to work with simple fasteners. For professional work, you will need tools with a speed of 800 to 1200 rpm.
Torque
For household and low-power screwdrivers, the torque value is 8-15 Nm. For furniture production and other serious tasks, tools with a rating from 23 to 50 Nm are suitable. Professionals are recommended to purchase screwdrivers with a value from 60 to 140 Nm.
How to choose the right screwdriver
To make a choice in the direction of a reliable and high-quality screwdriver, you need to know some important characteristics of the tool.
Engine types
Motors used in screwdrivers are divided into 2 types - brushed and brushless. The brush (collector) version has brushes for collecting electric current. The advantage of such a motor is its low price. The disadvantage will be a low percentage of efficiency.
Brushless (inverter) motors have more positive aspects:
- Long service life.
- Tolerance of irregular overloads.
- Wide speed range.
- The efficiency is 30% higher than the brush motor.
- The speed does not decrease when a load is applied to the cartridge.
- There is no sparking, so it can be used in areas with a high fire hazard.
A significant disadvantage of such engines is their high price tag, which is why they are used more in professional environments.
Torque indicator
The minimum torque in screwdrivers is 6 Nm . Household modifications range from 8 to 23 Nm . Semi-professional tools come with a torque of 80 to 110 Nm . For professional units, the torque starts from 110 Nm and reaches 200 Nm .
Some impact screwdrivers with a torque of 120-140 Nm can be used as an ice drill for ice fishing.
Screwdriver and its types
A screwdriver is a hand tool that is designed for tightening and unscrewing screws, self-tapping screws and screws. It can be pneumatic or electric with varying degrees of torque, which must be taken into account when purchasing such a tool for home work.
The division into types is due to design differences. Thus, there are three types in total:
- electrical;
- pneumatic;
- hydraulic.
A pneumatic screwdriver is suitable for absolutely all household work. It is good in reliability and relatively cheap to operate, and is also suitable for use in the presence of flammable mixtures in the air: propane, butane, and so on.
When it comes to professional work, you need to start from the tasks first. And, therefore, there can be no talk about any universal option.
What is the price of a screwdriver
Of course, price is always a factor. This is important to understand the price/quality ratio of the screwdriver. There is such a wide range of prices for these devices that it can be difficult to tell if it's worth the extra money or not.
Don't choose the most expensive one and assume that it is the best electric screwdriver simply because it costs the most, because this is not true in all situations. You'll want to look at all aspects of your planned use first because you can save a significant amount of money this way! I chose a screwdriver that is in the low to mid price range and think it is worth the money spent.
Which screwdriver is better? Review of the most popular screwdriver models
If you decide to purchase a screwdriver, then when choosing the most suitable model you should be guided by such characteristics as power, battery capacity and ergonomics. When choosing a screwdriver, you should also take into account the conditions in which the tool will be used. In this review, we will look at products from the most well-known manufacturers, and we will touch on both budget and more expensive and productive models designed for use for professional purposes.
