Additional functionality
In branded models, the manufacturer, in addition to the standard features, also offers the user auxiliary functions. They greatly facilitate work and can become a point over and, dispelling doubts whether it is worth buying this or that model.
Most often found in tools:
- Charge indicator. A small light that will tell you when you need to put the battery on recharge;
- Reverse move. And he will unscrew the screw, and the drill will be able to take it out of the thick board;
- Impact mechanism. Indispensable if you need to work with a stone surface or brick;
- Illumination of the workplace. In some screwdrivers, it is so powerful that there is no need for extended lighting.
There is also an impulse, various blockers, speed switches, etc. Every additional feature. This is a plus to the price of the device, which means that you need to be 100% sure of its need for the device.
Voltage and other parameters
For an ordinary buyer of a screwdriver, it is enough to know:
- In household appliances, the voltage ranges from 10-14 V;
- For professionals, the indicator should be higher. From 18 V. Some instruments boast a 36 V level.
The next characteristic. Power. The parameter informs the user about the speed of the device. It is logical that the higher the power, the faster the screw will be screwed in. But it is not worth overdoing it, for household purposes and do-it-yourself routine repairs, a 500-700 W model is quite enough.
In order not to send the device for charging every half hour of operation, it is worth Paying Close attention to the battery. Modern screwdrivers use:
- Lithium-ion batteries. Not susceptible to self-discharge, the most common. They can be charged up to 3000 times, and at any stage and discharge level.
- Nickel-cadmium. They are not afraid of the cold, they work productively at subzero temperatures. However, there is a small drawback. Self-discharge. You need to store such a battery with 0% charge in order to save capacity to the maximum.
- Nickel-metal hybrid. Eco-friendly batteries, which are equipped with some tools of European brands. These batteries are compact and lightweight, but are frost-resistant.
Comparing the characteristics of the battery, it is also worth looking at the capacity. The autonomy of the device and the number of possible recharges depend on it. Over time, the capacity decreases, this also needs to be taken into account.

Screwdriver. It is essentially an electric screwdriver replacement. He performs the same functions as the younger fellow, only makes the process of tightening / loosening screws and bolts much faster. Such a tool is especially effective if there are screws. Dozens or even hundreds. The device can not only twist the screws. I installed a special drill, with a screwdriver you can make holes in wood, plastic and thin metal. powerful devices even take bricks and concrete. In general, the tool is indispensable in everyday life and in repair.
Manufacturer focus
Battered truth. The brand is beyond competition. Yes, branded tools are more expensive, but they have a quality guarantee and service centers for repairs, and the screwdrivers themselves are made of durable components.
Quite good screwdrivers with a removable battery are also offered by Varo Kreator, Sparky, Dnipro-M and others.
Torque
The numbers in the characteristic show with what force the screwdriver twists the self-tapping screw or how much force is required to overcome the drilling load. What is the practical use of knowing the parameter? The diameter and length of the bolt to be screwed in depends on the torque. The higher the indicator, the longer and thicker the screws will be used in work, and not fearing failures or breakdowns. For example, at 40 N / m it will turn out freely drive in self-tapping screw 10 cm long.
In small household models, the torque is from 10 to 30 N / m, but the indicator can be adjusted by adjusting to the nozzle. A limiter is provided on the screwdriver body for adjustment. The ring immediately after the chuck. The user can coordinate the effort for a specific screw by scrolling the limiter. Result: as soon as the self-tapping screw is tightened to the desired level, the chuck will stop, although the motor will work.
Interesting: The stop does not only help to tighten the bolts by preventing excessive sinking into the material, but also protects the tool from wear.
Criteria for choosing a cordless screwdriver
To choose a quality screwdriver, pay little attention only to the price, appearance and comfort in the hand. It is necessary to additionally evaluate a lot of characteristics. Those who DO NOT believe the consultants can independently study the technical passport of the device they like. It describes the main parameters and capabilities. What is important when buying a cordless screwdriver and which device is better for the house from inexpensive ones is described in detail in the following sections.
Choosing the type of battery: basic recommendations
When deciding how to choose the right screwdriver, special attention must be paid to the type of battery used. There are these types of batteries: Li-Ion, Ni-Cd, Ni-Mh.

In the process of wallpapering, read here.
Tool power
Cordless screwdriver runs on lithium-ion, nickel-cadmium batteries.
To choose the right screwdriver, you need to pay attention to its power. There are two parameters:
- Soft torque represents the maximum force when twisting or unscrewing, the tool speed in this case is from 0 to 350 rpm. / min;
- If we talk about hard torque, it displays the work of the tool during drilling, the rotational speed is 0-1000 rpm. / min.
productive and powerful is the screwdriver with the above indicators. For example: if it is necessary to screw a screw with a length of 70 mm into a wooden surface, a torque of 25-30 N.M is enough, but if it is necessary to screw a self-tapping screw up to 100 mm long, it is necessary to take models with a torque of more than 40 N.M. If necessary, tighten longer self-tapping screws, you first need to drill a hole.
Availability of additional features
Depending on the model, screwdrivers can have a number of useful additional functions:
- The hammer mechanism makes it much easier to drill holes in concrete and brick.
- There may be an impulse, this is convenient when you need to, for example, Unscrew a stuck screw, and there is an opportunity to press the tool well.
- The presence of a speed regulator will allow the use of a screwdriver as a full-fledged drill, such models can develop more than 3000 rpm. / Min.
- If you plan to frequently use the tool to work in hard-to-reach places, then the presence of a backlight will greatly facilitate your work. It is even better if the illumination is located on top of the battery pack, but in some models it is placed above the start button, which is less effective.
Recommendations for choosing a tool for home use
For infrequent use of the screwdriver at home, if mobility is not important to you, the network model will suffice. If the cordless screwdriver will be used frequently, Ni-Cd or Ni-Mh batteries should be used. If the instrument will be used frequently, a model with a Li-Ion battery should be preferred.
To use this tool periodically at home, it will be enough to purchase a model in which the torque is within 25-35 N.M and the battery capacity is 1.5-2 A.H.
How to Choose a Drill Driver with Ni-Cd Battery
Batteries of this type have been used for a long time, they are designed for 1.5 thousand charge-discharge cycles. The advantage of such models is that they can operate at low temperatures, up to 15 C, have a low cost and a service life of about 5 years.
As a disadvantage, it is worth noting the long process of charging the battery, which has a lot of weight and memory to charge. In order not to reduce the battery life, it must be completely discharged and recharged.
In order to completely discharge such a battery, you can use a flashlight, which is often present as an additional function. Such screwdrivers must be completely discharged before long-term storage.
How to choose a drill screwdriver with a Ni-Mh battery
This type of battery is between the Li-Ion and Ni-Cd models. The popularity of this type of battery is much lower, this is explained by the fact that they are designed for only 1000 charge cycles. The battery also has no memory to charge, practically does NOT self-discharge, but its main drawback is its large weight.
Electric screwdriver device.
In order for the screwdriver to work normally, after long-term storage, it is recommended to completely discharge the battery, and then charge it again. If you plan to NOT use the battery for a long time, fully charge it before storing.
If you decide to choose a screwdriver yourself, you need to pay attention to such a battery indicator as capacity. The higher the capacity, the more work you can do on a single battery charge.
Tool torque indicators will directly depend on the battery voltage: the higher it is, the more powerful the screwdriver.
There are also network models, but they are more intended for professional use or for one-time household work, dependence on the mains and wires, which interfere with work, are their main disadvantages.
Minuses:
Very high price of the battery;
Risk of explosion if the housing is damaged;
The battery is afraid of a full discharge, which can damage it;
Poorly tolerate low temperatures;
Passive aging, even with complete rest, gradually loses its capacity.
When buying a Screwdriver, you need to Pay special attention to the date of manufacture of the battery: Two years of age of the battery can indicate a 30% loss in capacity.
Nickel-cadmium batteries (Ni-Cd)
It has been on the market for a long time. Batteries of this type are short-lived. 1.5 thousand cycles discharge / charge. The service life of such batteries is longer than that of lithium-ion, on average about five years.
Netherlands:
Screwdriver batteries.
There are currently 3 types of batteries:
Ni-MH, nickel metal hydride;
Li-Ion, lithium-ion;
Ni-Cd, Nickel-Cadmium.
A little more detail about each type of battery:
Lithium-ion batteries (Li-Ion)
The most common type of battery today. Designed for 3 thousand battery recharge cycles.
In our time, it is difficult to imagine a more or less serious repair without using a Screwdriver. They come with battery power and mains power, as well as from a pneumatic drive. The last two are used mainly in stationary workplaces.
Pros:
High capacity battery;
Lack of memory effect batteries;
Low self-discharge, about 20% per year;
Short battery charging time, from half an hour to 4 hours, depending on the battery capacity.
Let’s go through the list a little. By the way, it should be said right away that most of the above is still produced in China.
AEG. Rarely found in everyday life, but the tool is of very high quality, low popularity in our country is explained by the lack of promotion of the brand.
Bosch. The tool of this company can be described as a strong average at a price above average.
Dewalt. Essentially the same as Bosch, only an order of magnitude cheaper.
Metabo. Basically, the same Bosch, only inside more electronics.
Makita. The tool of this manufacturer is considered the best in terms of quality / price ratio. These are the screwdrivers they do best. It should be noted the high-quality assembly, reliability and ease of use. NASA astronauts use Makita products.
Hitachi. This manufacturer’s tool has the same reputation as the Makita, except that it’s a bit simpler.
Black Decker. The products of this manufacturer are unpopular with us due to and a small number of service centers.
Hilti. An exorbitant price with average characteristics. The main focus is on special conditions of service and warranty service.
Interskol. The very thing for the house and the cottage. Reasonable cost (3000. 4500.) With good quality and reliability. Higher in price. This is the lot of professionals.
One more point to remember when choosing a Screwdriver. This is the ergonomics of the instrument. When buying, take the Screwdriver in your hand, Feel how it lies in your hand, is it comfortable for you to hold it, and does the handle slide in your hand, is there a backlight, what material the body and the handle are made of. The weight and size of the tool is also important, whether it will be convenient to work in narrow places, but at the same time it is worth remembering that a heavy and large Screwdriver tightens screws much easier, such a model is more suitable for drilling or woodworking.
Screwdriver power
The capacity of cordless models depends on the operating voltage of the battery. It ranges from 1.2 to 36 V.
- For simple work, 3-6 V (Volts) is enough.
- For screwing into wooden beams, plastic and drywall, optimal 10-15 V.
- For drilling hard materials. Minimum, 18V.
The more power, the more functionality in the screwdriver. Powerful models are heavier than their own fellows.
Tool performance is directly related to the work of torque (force). The more powerful it is, the more tighten the screw or drill the hole deeper.
For homework, screwdrivers of three powers are chosen.
- Stronger: Torque 30-40 Nm (Newton meters) and above. Professional models Equipped with torques up to 130 Nm. In addition to twisting Equipped with the function of drilling hard surfaces.
- Normal: With a force up to 20 Nm. It is easy for them to unscrew / tighten bolts and screws on drywall and plastic.
- If only Twisted. This is a cordless screwdriver. Its torque is about 10 Newton meters. Suitable for working with small fasteners: Repair children’s toys or tighten loosely clamped furniture bolts.
In most screwdrivers, the maximum torque is adjusted using a limiter. Rings with digital markings, located on the chuck. You will be able to set the optimum torque to tighten the screw. The more graduations in the limiter, the more accurately you can meter the torque element.
Sparky BUR2 10.8li-C HD: 20 torque steps drilling
A separate division is provided to determine the drilling coverage. Therefore, the rotation speed in screwdrivers is indicated in two ranges:
- Unscrew the screws on the low one. It ranges from 400 to 800 vol. / Min.
- Drilled on a high. In professional models, the rotation speed reaches 1300 rpm. / Min.
Choosing a screwdriver: for home and for work
Difference between home and work screwdrivers In power and functionality. Accordingly, their tasks are different.
- With the help of household models, you can change the lock, hang a mirror or assemble furniture. They are designed for tightening bolts, screws and self-tapping screws. Designed for short-term operation.
- Professional screwdrivers, in addition to screwing, are equipped with the function of drilling hard surfaces. They are tough: able to work non-stop for eight hours, five days a week.
Choose screwdrivers for two parameters.
How to choose a screwdriver
Battery type
Here the battery depends on how quickly the tool is discharged. And if the question became an edge: How to choose a cordless screwdriver? It is worth understanding the types of batteries.
- Li-Ion (lithium-ion). They have the highest power and, in comparison with other batteries, the highest number of charges. Up to three thousand times. They are lightweight, fast charging and have no memory effect. To extend battery life rather than charging / discharging it to the end, store it half charged. There is only one drawback:
- Works intermittently in the cold.
Ice screw battery
Obviously, you will have to choose only from models that run on a battery, since there will be no access to the network while fishing. In this regard, it is worth noting three options for batteries for a screwdriver:
- Li-Ion cell. These batteries charge quickly and are lightweight. But they also have a serious drawback. Intolerance to severe frost.
- Nickel cadmium battery. In this case, the situation is reversed. The battery can withstand temperatures up to 150 ºC, but its mass makes storms much heavier.
- Nickel-metal hydride elements. If you need a medium-weight ice screw for a screwdriver, which is NOT planned to be used regularly, then this option will do. It weighs less compared to the previous battery and does NOT cause any particular problems in the cold.
Summing up in this part, then according to the totality of characteristics and based on the experience of experienced fishermen, nickel-cadmium batteries should still be called the optimal solution. Despite their heavy weight, such batteries provide the highest degree of reliability in cold conditions. And this is a key advantage for the angler in the winter.
Advantages of ice screws from a screwdriver
Comparing the hybrid design, including the auger and the drill, with the automatic ice screw and modifications from the chainsaw, it can be assumed that there are many disadvantages to such a device. And yet, experienced fishermen Not only for the sake of economy prefer a screwdriver for an ice screw. How to choose an option in terms of power and size. This is decided in each case individually. It is only important not to forget about the minimum power and torque indicators. However, experienced users note other benefits. This is, first of all, ease of assembly, functionality, reliability and ample opportunities for improvements.
Adapter for an ice screw for a screwdriver
With the help of the adapter, the screwdriver is connected to the working part of the device, that is, to the drill. In principle, with the help of such an adapter, you can make a full-fledged power tool from any auger intended for manual use. The main thing. The dimensions of THESE components are correctly matched.
The adapter is equipped with a special shaft on the brown side and a hex head for a screwdriver. The parameters can be as follows: the length of the shaft is 6.8 cm, and the gap from the attachment to the end. 2.6 cm. For the scheme “adapter. Ice screw. Screwdriver” has been correctly formed in practice, you should pay attention to the diameters. Again, standard sizes range from 1.8 to 2.2 cm. It is advisable to purchase adapters with handles and a special stop to protect against falling out. It would seem that any structural addition will reduce the performance of the drill during operation. Nevertheless, avid fishermen note that in their work, convenience in handling the device comes to the fore, and the power of the screwdriver in most cases is enough with excess.
The main criteria for choosing a screwdriver
As in the case of any other tool, it will be useful to estimate at least the average complexity of the upcoming ice work. Approximate data will allow you to make a more accurate choice. If it is supposed to work with a universal device, then two main indicators should be taken into account. Power and torque, which will have a screwdriver for an ice screw. Which device to choose in terms of performance. In this matter, it is worth starting from tension. The power should be at least 18 V. If you need to work with thick ice and you have a good sum of money on your hands, you should not abandon the model with a voltage of 36 V. It is this characteristic that will determine what the power potential of the ice screw will be, and its ability has penetrated the most problematic layers of ice cover. Also, DO NOT forget about torque. This parameter varies on average from 50 to 70 Nm. This value will determine the rotation speed of the auger. Again, the higher the torque, the easier the drilling task will be.
How to choose a screwdriver for an ice screw? Tips from experienced fishermen
On ice fishing, an ice screw is just as necessary as a baited rod. Today there are problems with such equipment, since the market offers many specialized automatic drills. Nevertheless, the cost of such devices makes a considerable part of anglers turn to alternative and, as a rule, cheaper options for such devices. Experts in winter fishing recommend that you immediately focus on a screwdriver for an ice screw. Which to choose. This is the main question, as there are several criteria for evaluating a suitable device. But choosing a basis for b is not enough. You also need to know the assembly technique for such inventory and other nuances.
Assembling the ice screw
At the stage of final assembly, there should be three main elements at your disposal. Among them are the auger itself, a screwdriver and an adapter. It is best to use components from the same company. In particular, purchase storms in one set with an adapter, and then connect the device to a drill. If you have to deal with different designs, then initially it is desirable to purchase models with hinged joints. This configuration expands the options for assembling an ice screw from a screwdriver. How to make a homemade electric drill from different parts? If the components match each other in terms of their diameters, then it will be enough to securely fix the auger and screwdriver from different sides of the adapter. If there is a difference in diameters, then the adapter will have to be modified. This element has two parts. Shank for b and hex for drill. Usually, all possible alterations involve the inclusion of an L-shaped hex key into the design, which is selected strictly for the required dimensions.
