The Difference Between A Screwdriver And A Screwdriver Drill
The main differences between a nutrunner and a screwdriver
An impact wrench is often called a tool for professional work, and a screwdriver is often called a household tool. There are several of their key differences:
- The dimensions of the wrench are often larger than those of the screwdriver. Their weight is also different. the wrench is heavier, but it has a good positive difference in power.
- The impact wrench has no chuck attached. Instead, it has a special holder that secures the nut head. an extension that allows you to work with nuts. To use bits or drills on the nutrunner, you will need to install an adapter.
- The impact wrench is able to apply more force to the fastener. This allows the nuts to be ripped off, even if they seem to be firmly rusted to the bolt.
- Wrenches and screwdrivers have additional functions. Some models may differ in the presence of a speed controller, multiple speeds, backlight, etc. The screwdriver also often has a keyless chuck and a 2- or 3-speed gearbox.
- The screwdriver mechanism is not suitable for tangential impact.
These features allow the use of impact wrenches for work requiring more loosening power. Screwdrivers are used for simple work. By the way, if you use a wrench to screw in screws, you can damage the mounting head with a tangential impact or twist the screw. But, if for any reason you need to tighten the fasteners very tightly, the wrench will make it much more efficient.
What is a screwdriver?
It is an electric hand tool designed to work with a variety of fasteners. Use a screwdriver to unscrew and screw in screws, bolts and self-tapping screws. Its use allows you to significantly speed up the work, especially if you need to tighten several hundred fasteners. Furniture assembly, renovation work, construction. all these work can be done faster with a drill-driver.
Screwdrivers differ among themselves according to several criteria:
- Depending on the type of power supply, network and cordless screwdrivers can be distinguished.
- There are impact and non-impact screwdrivers, which differ in the presence of impact mode.
This tool has several additional features and uses:
- An electric screwdriver can replace a not very powerful drill.
- With the appropriate attachments, the screwdriver becomes an excellent alternative to hex wrenches.
- If the instrument has a backlight function, it will be useful when working in low light conditions.
- An adjustable ratchet mechanism allows the heads of the mounts to be positioned exactly on the surface of the material, improving the appearance of the product.
Advantages and disadvantages of impact wrenches
One of the key differences between the impact wrench is the tangential impact. When unscrewing, the tool first rips the nut off the bolt and then unscrews it. This approach allows you to work with rusted fasteners without a wrench, without fear that the nut will fly to the side due to the high unscrewing force. Impact wrenches are very useful when working with dimensional machinery.
One of the disadvantages of the impact wrench is the increased noise level, which is due to the high power of the tool. This is especially true for large powerful models. If you can use a screwdriver even at a later time, without fear of waking up the neighbors, then it is not always possible to hide the noise when working with a screwdriver.
Models of impact wrenches that do not have a well-thought-out system of tangential impact and the subsequent limitation of the unscrewing speed are not very convenient. They can damage the fasteners. However, in modern impact wrenches this drawback is eliminated.
Summing up, we can say that the impact wrench will most effectively prove itself in the hands of a skilled craftsman who knows exactly how and for what to use this tool. The screwdriver is suitable even for beginners, although it has not so much power.
Briefly about the features of the impact wrench
An impact wrench is a slightly more specific tool, although its principle of operation is a lot like that of a screwdriver. To distinguish a nut device from a drill, you need to pay attention to the holder. Its attachment is different from the one installed in a drill or screwdriver. The tool mechanism is best suited for working with bolts or nuts. He will be able to unscrew even rusted old fasteners.
There are several popular types of impact wrenches:
- Pneumatic (run on compressed air from a compressor);
- Gasoline (use internal combustion engines);
By the type of action, nutrunners can be divided into torque and impact. Torque are used for heavy work, their torque is from 1000 to 12000 Nm. The downside of the coin is a low rotation speed. 3-16 rpm.
It can be added that there are torque and impact wrenches according to the type of action.
Torque wrenches are used for heavy duty applications, with a torque rating of 1,000 to 12,000 Nm. The disadvantage of this type of nutrunner is its low speed (rotation speed 3-16 rpm). Impact wrenches are more widespread due to their relatively high power (from 100 to 4000 W) and relatively affordable cost.
A wrench is an indispensable professional tool that can be found in the assortment of any repairman or assembly worker. The most powerful models have found their application in mechanical engineering.
Wrench and screwdriver. what is their difference?
Many different tools are required for repair or workshop work. There are universal ones that can solve most problems, and there are those aimed at narrow application. A striking example is a screwdriver and a wrench. Despite the similar principle of operation, these tools have differences that make them useful in different situations. Further in the article, we will analyze what is the difference between a nutrunner and a screwdriver, as well as in what cases this or that tool will be needed.
Is it possible to make a wrench with your own hands?
If you have a screwdriver, you can use it as a wrench without purchasing a separate tool. Of course, the power of the tool will remain small, but it will still help to significantly reduce the time of working with nuts when changing wheels for cars. It is enough to install the desired nozzle (head) on the screwdriver, the dimensions of which will coincide with the parameters of the special key. This can be done using an adapter. To loosen the nut, you will need a wrench, since the power of the screwdriver is unlikely to be enough for this. However, after doing this, you can use a homemade impact wrench to speed up the process. This way you can remove the wheels in a few minutes.
Summing up all of the above, it can be noted that the impact wrench is more specific, high power and the presence of a tangential impact. It is most effective when working with nuts and bolts. In turn, the screwdriver is used for easier work, it quickly unscrews and tightens screws, self-tapping screws, etc.
Difference between drill and screwdriver
In the modern market for power tools, you can find a wide variety of options that significantly facilitate construction, finishing and other types of work. When it comes to comparing a screwdriver and a drill, many people simply do not see any difference in these devices. Of course, they can be understood: in appearance, both power tools are very similar, even more. they can perform the same function. For example, many craftsmen use a screwdriver as a drill. that is, using a special drill, they make a hole (the main purpose of a drill). However, there is a difference between the two considered devices, and it is significant. In this article, we will focus primarily on the signs of the difference between them.
A screwdriver is necessary for tightening and unscrewing self-tapping screws and small bolts. The power tool has a built-in mechanism that stops the rotation of the chuck at the moment when the resistance of this rotation reaches its maximum. This is a very important point, because the mechanism prevents damage to the screwdriver attachment. By the way, you should definitely take into account that the above-mentioned mechanism is adjustable. Today, there are two main types of devices: screwdrivers that operate on the mains, and models that operate on a battery. Of course, the price of power tools is different.
Cordless screwdriver DeWALT
A drill is needed to drill holes on various surfaces. It is widely used in construction, decoration, carpentry and assembly work. An interesting fact is that the first electric tool for drilling holes appeared in the middle of the 19th century, and since then it has been constantly improved. The modern drill has two modes of operation: normal and percussion. If in the first case everything is more or less clear. a drill is necessary to drill ordinary holes in the wall and wood surfaces, then in the second one should be slightly more precise. Impact mode is activated when it is necessary to drill holes in stone or concrete, i.E. In harder surfaces.
Impact drill BOSCH to contents
We have already found out that these power tools perform completely different tasks. But the main differences do not end there:
- The rotational speed of the screwdriver cartridge is significantly lower, plus there is no inertial moment. In other words, as soon as you turn off the screwdriver (release your finger from the button), the chuck immediately stops, while at the drill it spins for some time by inertia.
- Safety engineering. To work with a drill, experts recommend wearing safety glasses so that small particles formed during the drilling process do not get into the eyes. The screwdriver does not need to follow special safety precautions, you just need to be careful and careful when working with the attachment.
- Various operating modes. It was already noted above that the drill can be turned on both normal and percussion mode. Screw gun is regulated only by rotation speed, no more.
To the content
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 work of the striking mechanism will say that such a unit is better, and that 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 on the instrument, the wrist and hand of the master are much less tired, which allows to increase the same productivity.
- Given that even a strong wall is not able to successfully withstand the onslaught of such a tool, it usually does not deform the fasteners, which in the future will allow it to be removed without additional efforts. 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, such a 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 twisting 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.
How to choose?
When choosing a particular 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 significant 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 a large battery capacity, which extends 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 first ones 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 dangerous, and most importantly, it must be completely discharged and then fully charged, otherwise the "memory effect" will provoke rapid wear of the carrier.
At high voltage, the engine power also increases, but for home use sky-high rates are not needed: 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 maintenance can be done 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 is rather high. Models with continuously variable torque control are in priority, since they are more sparing for fasteners and surfaces that are drilled.
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 sensible usage tips.
For example, if possible, do not set 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 is even 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.
Always wear protective goggles and gloves, especially with delicate 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 something with it. such experiments often end with a burnt out engine.

One of the peculiar 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.
What is it and what is it for?
An impact screwdriver is a special power tool that allows you to most effectively 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 rotation itself, but also with the help of directed 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 comes across an obstacle of particular hardness. In a way, it’s a little jackhammer.
Impact screwdriver. the device itself is more complex and "smart", so a certain versatility should not be surprising. This means that the tool, as a rule, is fully compatible with various attachments, due 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.
It is logical that such a tool is somewhat more expensive than non-impact models, however, 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 on a daily basis. according to them, for all its assertiveness, the drill of an impact screwdriver 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. The logic of dividing tools into drills, screwdrivers and screwdrivers confuses most of all, 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 one is good for small 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 use on the street, when the working site does not imply the presence of functioning outlets.
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.

What is the difference between a drill and a screwdriver: features and differences
Among hand-held power tools, the drill and screwdriver are among the most common. They dramatically increase efficiency wherever you need to drill holes or handle screw fastening materials. These electrically powered tools can be powered by an ordinary power grid, compact batteries, compressed air and even gasoline. Rotation in them can be combined with percussion functions.
What is a drill
The first drills appeared in ancient times and made it easier to make holes in stone, wood, and other materials. When the electric motor was invented, their capabilities expanded significantly. And with the development of metallurgy and the advent of special drills, they began to make holes in metals and stone with the help of an electric drill. Over time, in addition to production, these tools began to be widely used in the household. Their functions were gradually expanded. Special devices were invented that made it possible to grind various surfaces and polish them.
The invention of abrasive cut-off wheels made it possible to use the drill for small-scale cutting work, primarily on pipes and metal rods. Modern drills are characterized by high power, high rotational speed and ergonomics. For them, various options for drills, replaceable chucks, special nozzles and accessories are made to expand the scope of use. For example, with the help of special nozzles, various building mixtures and paints are stirred with a drill. Drills can have normal and impact modes of operation when you need to drill stone or concrete.
There was a division into a professional tool and one that can be used in everyday life. Professional is distinguished by its reliable design and durability, widespread use of rolling bearings. Its parts are made of heat-treated alloy steels. The body is made of high-strength plastic, the lubrication system is closed.
The drills have acquired a convenient housing shape, which houses the electric motor and their control devices. They had switches, power regulators, impact mechanisms, and other useful devices. It became possible to use drills for tightening and unscrewing screws, screws, self-tapping screws.
Why do you need a screwdriver
Equipping drills with compact rechargeable batteries contributed to the creation of screwdrivers, which opened up new possibilities for carpentry, assembly and other work. They turned out to be especially convenient in confined spaces, when dismantling and assembling wooden and metal structures, installing plasterboard parts.
Outwardly, this tool is not much different from a drill. However, it has been specially designed to work quickly with screw connections, screws and self-tapping screws. There are models that can perform drilling operations. Screwdrivers are designed to provide powerful torque. Here high rotation speed is contraindicated. This is provided primarily by a special gearbox that reduces the speed to 200-300 per minute with a simultaneous increase in torque. Such a gearbox is controlled by a special regulator that sets the force required to tighten without deformation of a screw, screw or self-tapping screw.
To counteract jamming, a reversing device with several speeds is installed, as well as an overload warning system. The screwdriver can be equipped with attachments that allow you to loosen and tighten the nuts. Impact driver drives screws or nuts using a series of moderate, high-frequency impacts.
A special release clutch controls the tightening force. It also stops the cartridge in case of overload. The use of batteries combined with a screwdriver handle made it extremely popular in construction, assembly production, and in the repair of machines and mechanisms. With a replaceable power supply, the screwdriver can function for a long time, which can be increased with the use of the most advanced rechargeable batteries.
Feel the difference
The drill and screwdriver are good for performing the functions for which they were created. The drill makes it possible to quickly and accurately drill a hole. With the help of a screwdriver, self-tapping screws, nuts, screws and screws are also quickly twisted and unscrewed. At the same time, both instruments have certain differences.
- The drill holder in the drill is a keyless chuck, for a round drill in diameter. The screwdriver uses special holders designed for the hex tail of the working bit.
- The drill, even when adjusted, does not provide the correct tightening of the fastener, which can damage the screw head or the screwing attachment.
A special clutch is installed in the screwdriver, which allows you to adjust the force. As a result, the screw or self-tapping screw is twisted to the desired depth.
- Drills for drilling require a torque of 20 Nm and a speed of over 1500 rpm. A screwdriver only needs 10 Nm and 500 rpm for tightening.
- Professional drills in continuous operation work less than the same screwdrivers, which wear less.
- In an electric drill, it is possible to change the rotation speed. This cannot be done in a screwdriver.
- The electric drill has inertia after it is turned off, which requires increased attention during operation. The screwdriver stops instantly.
The screwdriver can only be used for tightening self-tapping screws, since it has only a hexagonal seat for the bits. Although it should be said that there are also drills with a hexagonal fit, like bits, but usually they only come in small diameters, and they are not everywhere on sale.
Thus, for this tool, we conclude that it can only be purchased for tightening self-tapping screws. At the same time, remember that it is tied to the network, which means that it will not work to work with it autonomously.
It is most convenient to use this unit in any assembly workshop, where work is carried out at one workplace to screw in self-tapping screws or screws.
What is the difference between a drill and a screwdriver?
Hello! In today’s article I will tell you how a drill differs from a screwdriver, since not everyone understands the difference between them and in the end they do not know what to choose.
To begin with, I propose to define the terms. If we start from the terminology of manufacturers, then screwdrivers they call the device shown in Figure 1. This is a network screwdriver with adjustable rotation speed, reverse, and also having a device thanks to which it is possible to avoid breaking the splines of the nozzle (bits).
And the manufacturers call drills both the machine shown in Figure 2 and the devices shown in Figure 3 and 4, which are popularly called screwdrivers (mains or cordless) or simply screwdrivers.
Picture 2 Picture 3 Picture 4
In order not to get confused, in this article we will assign the following names to each unit:
- I will call the tool from Figure 1 a screwdriver
- Figure 2. drill
- From figures 3 and 4. drill driver.
At the same time, I note that the difficulties of choosing arise precisely between the last two types, since everything seems to be so clear with an ordinary screwdriver. But I will describe all three devices early.
The main function of the drill is drilling. However, if there is an adjustment of revolutions and reverse (and they are now on most models), it can also be used as a screwdriver.
However, they lack any mechanism to automatically prevent bit stripping.
Therefore, here you have to rely only on your hands and head.
On the drill, the verdict will be as follows. Buy it if you are going to mainly drill. But keep in mind that sometimes it can also be used as a screwdriver. after all, it is in any case more convenient than turning with a screwdriver.
This tool is versatile. They can be drilled and screwed, without fear of spoiling the bit or unnecessarily drowning the hat into the material.
There is a customizable mechanism (popularly referred to as a ratchet) through which the rotation passes. When a certain resistance set by you is reached, it simply turns with a click, and the bit remains in place safe and sound.
In addition, the drill-screwdriver differs from a conventional electric drill also in that a gearbox is installed on it, which has a large gear ratio. Therefore, with the same engine power, the drill / driver has a greater torque value. This means that, for example, a power cord drill with a 400 W motor will have the same torque as a 700-800 W drill. However, the dimensions will be smaller.
The price paid for this is the lower number of maximum spindle revolutions. If on drills it reaches a value of 3000 rpm, then on drills their number is no more than 600-800. And if it is two-speed, then all the same, the revolutions will not exceed 1500 per minute.
Thus, we conclude that the drill-driver is a good universal option, since it can perform most of both drilling and screwdriving work.
However, such a tool will not replace a drill for jobs that require high chuck rotation. This is, for example, drilling a brick, when the work takes place in percussion mode. And although there is an impact mechanism on some models of screwdrivers, it is not very effective due to the low speed.
It is also worth remembering that they not only drill with drills, but also, for example, knead mortars using a mixing nozzle. And here, too, high speed is required. Therefore, for such work, a drill driver is also poorly suited.
Separately, it should be said about cordless drills. Firstly, it is drills-screwdrivers that are made with a battery, but there are no classic drills with a rotation speed of up to 3000 rpm with a battery.
Secondly, the use of battery technology has both advantages and disadvantages.
The pluses include the following things:
- Autonomy of work. that is, the ability to work for a certain amount of time away from power grids with pre-charged batteries;
- No wires, which is convenient, for example, when working on the roof.
The downsides are the following points:
- Aging of batteries. with frequent use, they usually last no more than 3 years, and if used rarely, they still age and in any case become unusable after 5-8 years, even if they simply lie idle;
- Impossibility to start working immediately if it suddenly turns out that the batteries are discharged.
These are my thoughts on the matter. I hope that after reading the article, you understand for yourself which tool you need. Let me finish on this. until we meet again!
