In the work of a home craftsman or professional builder, a special tool is required. It should be universal, allowing several actions to be performed during repairs using the same equipment. Among the electric tools, one of the most popular is the screwdriver. He can have various additional qualities. These include the possibility of an impact during the operation of the mechanism. This expands the scope of the tool.
Also, users mark such a model as Ryobi R18PD-LL15S. The kit includes 2 batteries. Sophisticated ergonomics allow you to work for a long time without hand fatigue. 2 speeds are provided, which increases the range of capabilities of the presented device.
General characteristics of the tool
Impact screwdrivers are designed to perform a number of functions that were beyond the power of the usual variety of such technology. This power tool is designed to screw in and unscrew screws, drill holes of various diameters, tighten, etc. It significantly speeds up the workflow, improving the quality of the final result.
A wide selection of models of such equipment is on sale. First of all, there are professional and household screwdrivers. Their characteristics correspond to the requirements of different categories of craftsmen.
There is also a cordless and cordless impact driver. Each of them has its own advantages and disadvantages. The specifics of the wizard allows you to choose the optimal type of device.
Today, the power tool market offers customers a large selection of domestic and foreign devices. Depending on the technical characteristics, the price for the presented equipment is also determined. When choosing an impact screwdriver, you need to have knowledge of the advantages and disadvantages of each model. This will allow you to make the right choice.
Difference of functions
Most screwdrivers on the power tool market today are semi-professional. This means that the equipment has improved qualities, but does not meet the requirements that are put forward for professional devices.
Almost all manufacturers make both powerful and simple models. The most popular is the Makita impact driver. Bosch, Metabo, and from domestic brands. “Interskol”, “Zubr”.
The professional tool is distinguished by the ability to work without interruptions for a long time, high power, as well as quick tool change. This type of device does not require too careful handling, it is distinguished by its endurance and durability.
Home screwdrivers are characterized by a more modest set of qualities. It should be said that in professional series of equipment there are also low-power types of products. For example, this is a Bosch Professional impact driver with a 10.8 V battery. However, they are ranked in this group due to their high build quality, well-thought-out ergonomics, and a long working resource. Such devices are indispensable, for example, in furniture assembly enterprises.
What to look for when choosing?
When you want to purchase an impact driver (mains or cordless), you need to pay attention to the factors determining the choice. First of all, experts recommend identifying the scope of this equipment. If the master uses the device once or twice a year, you can give preference to simple models. Their cost will be less than that of more powerful equipment.
However, even for a one-time use of the impact screwdriver, it is worth considering the future load. For example, when assembling a garage or other metal structure, you should not purchase the simplest, low-power devices. In this case, the work will take more time and effort. Also, experts do not advise purchasing the cheapest power tools from unknown manufacturers. Such equipment quickly fails.
If the master uses the tool in his professional activity, it is better to give preference to a more durable, powerful screwdriver. It will allow you to solve even complex repair tasks. The cost of this equipment will be higher than that of simple models. But the screwdriver quickly pays for itself when carrying out repairs or other actions at a professional level.
Type of food
When choosing a device, it is necessary to determine the type of power supply for the instrument. The cordless impact driver is suitable for almost anywhere. It does not require that there is a household network nearby, to which the instrument can be powered. The scope of application of the presented tool is extremely large.
However, the presence of a battery limits the duration of the wizard’s work. If the load on the tool increases, its duration of operation is sharply reduced. Cordless screwdrivers generally have limited torque. Therefore, the power of such equipment is sometimes not enough to carry out all the necessary actions during the repair. One of the best representatives of this class of devices is the Makita cordless hammer drill. This device is able to drill even hard materials, and also work for a rather long time without recharging.
For professional purposes, network types of devices are often used. They can function for a long time, and the cost of such equipment will be less. As a rule, these screwdrivers have a high rotation speed and power. The absence of a battery facilitates the design, making the presented device comfortable to use. But there is one significant drawback in the work of this class of screwdrivers. If there is no outlet nearby, it will not be possible to use such a device. This limits the capabilities of network equipment.
It is also worth considering that by choosing the most inexpensive network units, you may not get the desired equipment power. Therefore, when choosing a particular type of equipment, it is imperative to take into account its capabilities and correlate them with your needs.
Considering the impact screwdrivers on sale today. you should familiarize yourself with the main technical characteristics of household and professional models.
The power of network devices for home use ranges from 200 to 500 watts. The same figure for professional equipment is over 500 watts. If the master purchases a rechargeable device for household purposes. a device with an operating voltage of 9.6 to 14.4 V is suitable.This indicator for a screwdriver that works often and for a long time is from 14.4 to 18 V.
The battery capacity of the household appliance is 2 Ah, and that of the professional one is 4 Ah. Conventional screwdrivers usually do not have the ability to change speeds. Professional equipment has a wider range of functions. Therefore, there are 2-3 speeds in such devices. Their torque is 20 Nm or more. Household screwdrivers have this indicator at the level of 15 Nm.
In addition, specialists acquire a tool that is not afraid of stress, mechanical shock and even falling from a height. The cost of such devices is quite high. Therefore, for home use, more fragile, but cheaper power tools are used.
What is it and what is it for?
An impact driver is a special power tool that allows you to most efficiently drill walls in order to drive screws and install other fasteners. Unlike bumpless models, this relative novelty in the domestic market makes a hole not only due to the actual rotation, but also with the help of directional blows. The latter usually do not have a permanent character. the corresponding mode is turned on at the request of the operator or automatically if the drill runs into an obstacle of particular hardness. In a way, it’s a little jackhammer.
Impact screwdriver. the device itself is more complex and “smart”, therefore, a certain versatility should not be surprising. This means that the tool, as a rule, is fully compatible with various attachments, thanks to which the scope of its potential application significantly expands. instead of a drill, you can attach, for example, a hole saw or a mixing attachment.
A distinction should be made between an impact driver and a similar drill. The latter, being focused on making holes, assumes a longitudinal direction of impacts, while a screwdriver strikes as if longitudinally, due to which it significantly increases the torque.
It is logical that such a tool is somewhat more expensive than non-impact models, but its purchase is often justified even at home. the external, load-bearing walls of multi-storey buildings are usually distinguished by the highest strength, which only an impact screwdriver can overcome.
The device is also appreciated by professionals who drill walls or various parts every day. according to them, for all its assertiveness, the drill of an impact driver usually does not cause significant damage to the fasteners, increasing their durability. This characteristic is especially valuable in the context that the same tool is often used to assemble furniture.
The classification of impact screwdrivers is not so extensive, but it can still drive many inexperienced consumers into a dead end. Most of all, the logic in dividing tools into drills, screwdrivers and screwdrivers confuses, but in fact everything is extremely simple here: the mechanism is generally the same for everyone, and the exact name depends on the nozzle.
So, a drill is usually equipped with a drill for making holes, and a screwdriver and a screwdriver at the same time know how to screw in fasteners. Some models imply a simple replacement of nozzles, therefore they can have complex compound names like “screwdriver-drill”, but if such multifunctionality is not provided, the unit is called the most accurate term.
Often, when choosing, beginners are also confused by the fact that the device is supposedly electric and pneumatic. Electric models are the most common, especially at home, but pneumatic ones are perhaps very rare models that will definitely not be in demand at home, the main places of their use are various service stations and tire fitting enterprises.
Since the screwdriver is powered by electricity, it is impossible not to clarify that it can be both mains and battery. The first is good for minor home repairs or daily work in a well-equipped workshop, because it is lighter, and the master does not need to constantly remember to charge the battery.
However, it is the battery version that is the uncontested solution during the construction process or for outdoor use when the working site does not imply the presence of functioning outlets.
Impact Wrench and Impact Driver (Whats the “REAL” difference)
The use of an impact screwdriver will be safe and as effective as possible only if done correctly. Obviously, the first tip is to read the instructions before use, but there are other reasonable tips for use.
For example, if possible, do not expose the equipment to maximum torque, because many fragile materials with a treated surface can simply be torn from this, and you will ruin the workpiece. In addition, working at maximum speeds up tool wear, not to mention the fact that in this mode you need to hold it tighter, otherwise it may even be possible to get injured.
The modes of operation, by the way, are described in the instructions for a reason. each of them assumes optimal settings for performing this particular task, and for another it may not be suitable. So, drilling is needed to make holes, and the screwdriver mode is to screw in fasteners, when used, on the contrary, efficiency decreases, but the risk of injury increases.
It is completely unacceptable to change the settings on the fly, with a rotating chuck. this can break the unit.
Always wear protective goggles and gloves, especially with fragile materials. When drilling walls, make sure there are no electrical wires in advance. Remember that the continuous operation of the device is limited. if the nozzle or any other unit is noticeably warm, let it cool.
By the way, if the drilling mode is not provided for in a specific model of a screwdriver, then it is better not to try to drill anything with it. such experiments often end with a burnt out engine.
When using a cordless screwdriver in cold weather, be prepared for the fact that a battery of any type, especially a lithium-ion one, will discharge much faster, therefore you need to charge it more often.
How to choose?
When choosing a specific model of impact screwdriver, pay attention to the smallest details. The first thing that people usually pay attention to is the type of food. Pneumatic models will definitely not be needed at home, but electric models are network and battery, as mentioned above.
The network option is good for working in an equipped room, it is most appreciated for its almost unlimited power. Having given preference to just such a device, evaluate its cable. it must have a considerable length and thickness, have good insulation and not raise doubts about the strength of the place where it enters the unit.
In the case of the battery model, there are more selection criteria. First of all, you need to find a balance between the large battery capacity, which prolongs the battery life, and the weight of the device, because a capacious battery always weighs quite a lot.
Another point is the choice of the type of battery: today the most common lithium-ion models, but nickel-cadmium are also found. The former are good with a small mass with a significant capacity, they allow charging at any time, but they are more expensive than the main competitor and can wear out quickly at low temperatures. The advantages of the nickel-cadmium solution completely eliminate the disadvantages of the lithium-ion version. such a battery is cheaper and not afraid of frost, but it is heavy and environmentally hazardous, and most importantly, it must be completely discharged and then fully charged, otherwise the “memory effect” will provoke rapid wear of the carrier.
Batteries can produce different voltages, but for periodic household work, you can choose models with a value in the range of 12-18 V.
At a high voltage, the engine power also increases, but sky-high rates are not needed for home use: 500-700 W is enough, otherwise the tool will be heavy and unjustifiably expensive.
Screwdriver chucks, in which replaceable nozzles are attached, are quick-clamping and key. The first can be organized in different ways, but its advantage is that it can be serviced with bare hands. The key cartridge has a characteristic rim; a special key is needed to maintain it, which is not always convenient.
Since we are talking about the cartridge, an important criterion is the maximum diameter of its opening. the larger it is, the more different nozzles can be used.
Maximum torque is a measure of how hard the nozzle will rotate. This indicator does not always directly depend on the power of the motor, sometimes it can be increased due to the gearbox, but it is always desirable that the maximum torque be quite high. Models with stepless torque control are in priority, since they are more sparing for fasteners and surfaces that are drilled.
The last, but very important criterion for choosing a tool is its weight. Unfortunately, it is impossible to create a lightweight, and at the same time powerful and multifunctional device, therefore it is necessary to decide which is more important: lightness or performance. Keep in mind that with constant daily work, the first factor may be much more important.
When deciding whether to choose an impact or a shockless model of a screwdriver, first you need to figure out how they differ.
Many consumers who have managed to evaluate the operation of the striking mechanism will say that such a unit is better, and this is how they are ready to substantiate their point of view.

- Directed impacts increase the torque of the impact tool to a range of 80-250 N / m, making it possible to break through the most difficult obstacles. It is significant that in the process there is even no need to firmly press the case against the wall. the tool bites into it even without significant pressing.
- Without the need for constant physical effort applied to the tool, the wrist and hand of the master are much less tired, which allows you to increase the same productivity.
- Considering that even a solid wall is not able to successfully withstand the onslaught of such a tool, it usually does not deform the fasteners, which will allow it to be removed without additional efforts in the future. over, many models also provide for the reverse function of removing old fasteners from the walls, and even the fact that, due to long-term use, it has experienced strong deformation.
- The screwdriver works not only with bolts, but also with nuts, in each case achieving the most tight tightening. A “smart” car usually automatically switches from shockless mode to shock mode when it senses that the nut has become tighter at a certain moment.
Unfortunately, this solution also has certain drawbacks, which may never allow it to completely supplant unstressed models. Thus, an impressive twisting speed is observed only in the shockless mode; when switching to impacts, it significantly decreases.
Chucks for such a tool are not suitable for any. you need strictly hex. Most models do not have a limiting sleeve, so the degree of tightening must be carefully monitored by the operator, otherwise damage to the wall or parts will not be done. Finally, at high speeds, such a unit is capable of producing deafening construction noise, therefore constant work with it requires the mandatory use of protective equipment.

One of the original criteria for assessing the masculinity of the owner of the house is considered to be his ability to drive a nail (or, in a modern way, screw a screw) into the wall. Without this elementary skill, it will not be possible to hang a shelf, decorate a room with a picture, or install a curtain rod.
An electric screwdriver is called upon to cope with this task faster and without unnecessary effort, and the impact driver is especially often praised, but not everyone understands what it is and why.
If you purchased a rechargeable model, remember that the battery should always be in the disconnected position, except for direct work. In this case, the nickel-cadmium battery must be completely discharged before turning off the device, and then immediately put on charge. Among other things, it is still not capable of storing a charge for a long time even when it is idle, therefore sometimes it needs to be recharged, even if you have not used it.
A screwdriver gearbox may require periodic lubrication, an indicator that such a moment has already come is a characteristic unpleasant sound and a tight movement of the chuck when trying to rotate it by hand.
In the next video, you will find an overview of the impact and non-impact screwdrivers: AEG BS12CS vs BSB12C2.
Pros and cons of an impact screwdriver
If you have tried to drill concrete with an ordinary screwdriver, then you probably know how long, time consuming and thankless it is. An impact screwdriver easily copes with such a task, gives an advantage in working with brick and masonry, but still its effectiveness is far from the capabilities of a full-size impact drill and, moreover, a hammer drill. But in tightening screws and screws “with interference” impact screwdriver has no equal.
In addition, the tool makes it relatively easy to unscrew fasteners with a damaged cross or partially erased edges. Do not forget that with long-term continuous work, the percussion instrument does not load the wrist as much as the unstressed one.
However, the impact design can create a number of inconveniences:
- The pusher mechanism is subject to rapid wear, which is especially evident in inexpensive models.
- With the transition to the shock mode, the operating speed decreases significantly, and the noise level, on the contrary, increases.
- An impact screwdriver cannot be equipped with such useful components as a cam chuck (almost always hexagons are used) and a torque limiting clutch.
It is important to understand that the cost of a percussion instrument will be an order of magnitude higher than that of its unstressed counterparts, and this with a significantly shorter battery life.
Features of a shockless design
It is known that the simpler the design, the more reliable it is. Due to the absence of constant alternating loads, chucks and rotors of shockless screwdrivers are less susceptible to wear. Add to this the relatively low cost, small dimensions and weight, longer operating time without recharging. and we get a number of obvious advantages over a percussion instrument. So, if the main task of the device is to work with wood and soft brick, screwing in and unscrewing serviceable fasteners under light loads, then preference should be given to a shockless screwdriver.
Problems will arise when the owner of the tool has to face difficult tasks. The main disadvantage of a hammerless tool is its almost complete uselessness in drilling hard inelastic surfaces, such as concrete or stone. When working with damaged or hard-wired fasteners, there is a high risk of damage to them. the working head will simply rotate in the crosspiece or on the hexagon, without doing any useful work.
Impact or non-impact screwdriver: what to choose and in which case
The main feature that favorably distinguishes a screwdriver from a drill is its compactness and the ability to work independently. A few years ago, the operating time of the device without recharging was relatively short, but today, after the advent of more capacious and energy efficient batteries, manufacturers were able to significantly increase the mobility of screwdrivers and provide them with new functions. One of them is the percussion mechanism. Which is better. an impact or non-impact screwdriver, and what criteria should be used to choose this tool.
What and in which case to choose?
For professional use, powerful impact drivers from Bosch, Makita, Einhell, DWT and other well-known brands are the best choice. They will not let you down in construction and repair, they will help to cope with damaged or outdated threaded connections. It is better to give preference to models with a high spindle speed and a capacious battery.
At the same time, for home use, you should pay attention to cheaper models. The same firms offer entry-level impactless tools, in addition, good impact and impactless screwdrivers can be found from domestic manufacturers and Chinese brands, for example, Zenit, Vityaz, Intertool, Sigma.
Ultimately, the only thing you need to know for sure before choosing any tool is where, for what and in what conditions it will be used. Based on this, it is not difficult to choose a model that will fully satisfy all your requirements.
