What is the difference between a drill and a screwdriver drill

Screwdriver: main varieties, functions and design

Let’s start from the very beginning and decide. what is such a tool like. screwdriver? What is it made of and how does it function? The screwdriver body consists of two parts. The internal structure is a combination of electrical and mechanical components. The electrical components are the motor and the electronics control system, viz. trigger, speed and reverse switch, etc.

Mechanical components include: gearbox, which in turn can be single or multi-speed; a torque adjustment clutch, if available, and a spindle onto which the keyless chuck is screwed, or in some models. hex socket-holder, then the equipment is fixed.

The power supply system of the screwdriver includes a battery or a power cord. The basic principle of the screwdriver. energy change. Electrical energy is converted by a motor into mechanical energy, which, using a variety of transmission devices (transmission), drives the work equipment.

Which is better: cordless or cordless tool?

Energy source type. this is the first division of species that we will consider today. In the process of choosing the type of power supply to a power tool, much depends on the working conditions. After analyzing all the advantages and disadvantages of cordless and corded screwdrivers, you will ultimately be able to successfully choose a tool for your case.

Mains: the power tool is “powered” directly from the mains. One of the main advantages of this type is. time independence. That is, the power tool will work exactly as long as you need, and the power, and accordingly, the performance of the tool will be constant. This will provide great convenience if you require prolonged use of the power tool. But this is provided that there is an electrical network nearby and your movements around the work site will not be too active. Indeed, when working with a network tool, there is always the possibility of catching / stepping on, or even easily getting entangled in the network wire. It is worth considering the type of the socket outlet, because both the plug and the socket must be optimally matched to each other. And if the length of the power cord is not enough, then get a power strip.

In the event that you plan to use the hammer drilling function, you will need quite a lot of power, which the cordless tool can hardly develop. There is another rather important plus of the mains power tool. with identical power, its weight is an order of magnitude less than the weight of a cordless tool, since, naturally, a battery always weighs more than a wire.

Rechargeable: source of energy for work. rechargeable battery. Representatives of a portable type of power tools, that is, you will be able to calmly move around the work site without thinking about the wire. But long work is out of the question here, because the charge of the power source is clearly limited by the capacity of the battery, which requires periodic recharging. Also, some types of batteries with the end of the charge cause the screwdrivers to produce much less power. There are also differences in price: a cordless tool is an order of magnitude more expensive than a network analogue.

What is the difference between a screwdriver and a drill. screwdriver?

What is the difference between a screwdriver and a drill driver? Many do not see any major differences between these power tools, but they are still there. The screwdriver, first of all, is designed for serial work and performs the function exclusively for screwing / unscrewing screws and self-tapping screws. Quite often, this is a mains power tool. It is certainly possible to use it as a drill. however, it is not recommended to do this. Drills are not even indicated in the tooling in the catalogs, since it would not be rational to use them. Although it is possible to choose this element correctly, it is very difficult. This is due to the fact that the design of the screwdriver is simply not suitable for drilling. Instead of a keyless chuck (BZP), screwdrivers can have a hexagonal socket-holder, into which a bit is installed.

Let us turn our attention to the technical characteristics, namely the rotational speed. In network models, it is large, which gives its advantages when working, including with complex and even somewhat damaged fasteners. But when drilling, a large value of this indicator is rather a defect, especially if we take into account the fact that the speed limit is either completely absent in this case, or is performed in an extremely mediocre way. And the overall dimensions themselves make the screwdriver an unprofitable tool for drilling.

It is for this reason that cordless drills are becoming more and more popular every day. screwdrivers. Since this type of instrument is almost universal, the range of tasks that it can perform is much wider. Very compact, completely power-independent tool with drilling and driving / unscrewing functions. Such a device will come in handy in any home and will be simply indispensable for repair and finishing works.

Let’s compare the technical characteristics of the drill using certain examples. screwdriver and screwdriver. A screwdriver with the same power or battery voltage is “stronger” than a drill. screwdriver, this is shown by the values ​​of the maximum torque and tightening torque. Also, pay attention to the drilling diameter, in the case of a screwdriver, these columns are completely empty: the data is not indicated in the technical characteristics of the tool, because drilling is not typical for it. Now consider the rated speed or idle speed. At the drill. screwdriver, it is lower, but it has a comfortable adjustment, which allows you to better adapt the tool to new tasks during work. The same difference is observed in the type of shank. “Hexagon” or quick-clamping. The first is designed for a bit and is not convenient for a drill, while the second copes with a secure fixation of both.

What to choose: household or professional tool?

The professional screwdriver is designed for serial screwing of fasteners. This tool is highly resistant to wear and tear, and can work a full work shift non-stop without the danger of overheating. Professional models are made of more expensive and stronger materials. Each manufacturer selects and develops his materials, gaining the necessary set of qualities for his tool. There are more metal parts in the design of such a device, because of this, such a tool weighs much more. Naturally, professional and household tools differ in price.

Household power tools are more likely to be used intermittently. It is more affordable to the user, one might say. primitive to handle, lighter in weight.

They also differ in technical characteristics. Professional tools are much more powerful, the torque of such models is much higher. Even without looking at the technical characteristics, you can notice this by paying attention only to the torque limiting clutch: there will be much more adjustment values ​​there than on the household model. This, by the way, indicates not only the strength of the screwdriver, but also that a professional tool can be adjusted more precisely.

Torque clutch or screwing depth stop?

The torque clutch, also known as the torque adjustment clutch, serves to limit the “force” of the tool. It is a ring with a scale of values, the number of which depends on the magnitude of the torque. The larger it is, the more divisions there will be. The value is set by the user: depending on the size of the screw and the material in which it is wrapped. Adjustable and tightening value.

difference, drill, screwdriver

For the most part, power screwdrivers are equipped with a screwdriver depth limiter, since it is very convenient for serial use of the tool. It can be used to set the depth to which the screw will be wrapped. The limiter, unlike the coupling, does not react to the force of resistance of the material, which is also sometimes very convenient in practice. If, for example, we wrap a self-tapping screw in a tree and we encounter a seal, a screwdriver with a stop will still screw in the fasteners, and the coupling will stop working. But if it is too strong material, while there will be a chance of breaking the rig, be especially careful.

feel the difference

The drill and screwdriver are good for performing the functions for which they were created. The drill makes it possible to drill a hole quickly and accurately. Using 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 in diameter drill. 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 lead to damage to the screw head or the attachment screwing it in.

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.

difference, drill, screwdriver
  • 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 run less than comparable 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.

Drill and screwdriver differences

What is the difference between a drill and a perforator, from a screwdriver and what is better to choose

The question of how a drill differs from a perforator is asked by young masters. Indeed, at first glance, it may seem that these tools are the same, because they are both designed to create different holes. But the difference between them is significant, so before you go shopping for them, you need to find out about what is used for both “relative”.

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 for quick handling of screw connections, screws and self-tapping screws. There are models that can perform drilling operations. Screwdrivers are designed to provide powerful torque. High rotation speed is contraindicated here. 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 the screw, screw or self-tapping screw without deformation.

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 the handle of a screwdriver made it extremely popular in construction, assembly production, and in the repair of machines and mechanisms. With a replaceable power supply, the screwdriver can operate for a long time, which can be increased with the use of the most advanced rechargeable batteries.

The age-old question: which is better. a drill or a hammer drill?

In fact, this question is not very correct. In this case, we are not talking about “better” or “worse”, but about the expediency of such a purchase. For example, if the tool is purchased for the home, then the purchase of a perforator (given its high price compared to a drill) will not justify itself soon, because it is unlikely that you will drill and gouge concrete very often. However, if you have serious repairs ahead, in which you definitely cannot do without such work, the hammer drill will come in handy. Several holes in concrete can be drilled with a hammer drill, but it is not recommended to make a significant number of them. It is worth remembering that in some cases, repairs can even cost more than buying a new drill.

If the main part of the work for which the tool is intended is drilling plastic, wood and metal, then an ordinary drill will do just fine. But even in this case, it is best to purchase a model with a shock function. the difference in price is small, and the scope of application is much wider. However, over time it will be possible to add a perforator to your “arsenal”. in brick and panel houses it will definitely not be superfluous.

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 the difference between a drill and a screwdriver, and how this difference can be used?

There are also drills and screwdrivers on sale that can work in both modes. They are heavier and more expensive than screw-only models. However, their scope of application is much wider than that of simple screwdrivers, which means that such a purchase is more suitable for a home.

Using a drill without the function of a screwdriver for tightening fasteners is certainly possible, but not recommended. The fact is that even the smoothest stroke of this tool is not able to provide the correct force when working. In practice, this means that both on the head of the fastener and on the nozzle itself, the slots will most likely be torn off and it will be impossible to unscrew the self-tapping screw if necessary.

We understand the question: what is the difference between a drill and a screwdriver and which is better?

Screwdriver

A screwdriver is a hand tool made in the form of a pistol.

It is designed for loosening or tightening screws, screws, self-tapping screws, as well as other hardware with a thread with hexagonal or slotted heads.

It is often used at home and at work. Using a screwdriver, it is convenient to mount or dismantle furniture, roofing, fences.

If a special attachment is included with the tool, then it is also used for grinding surfaces and drilling holes, thereby the manufacturer has combined the drill and screwdriver in one tool. The screwdriver can be powered by an outlet or battery. Some models operate on compressed air (pneumatics). The design of the tool consists of a body, a fastener, electrical and mechanical parts, as well as a protection and adjustment system.

Components of the screwdriver design:

  • Body made of metal or plastic with a rubberized handle;
  • Electric (or gas) engine that turns the nozzles;
  • Planetary gearbox (transfers from the motor to the spindle with a clamp);
  • Adjustment clutch, which is connected to the chuck;
  • Clamp chuck (holds the attachment in place);
  • Electronic control unit (there is a reverse switch and a start button on it);
  • Battery or power cord.

For the tool to function, it is necessary to insert and fix a bit with a hex shank into the chuck. Also, using the coupling, the tightening torque is set (depending on the model, there may be 8-5 positions). When the start button is pressed, the motor is turned on, which, with the help of a planetary gear, starts to rotate the spindle and the chuck with the bit. The more force is applied, the higher the speed rises.

After the self-tapping screw is completely screwed into the surface, the resistance increases significantly. This will cause the ratchet to slip and stop the transmission. If it is necessary to unscrew the self-tapping screw, then the reverse comes into operation. It launches the attachments in the opposite direction.

To work with a screwdriver, you do not need to adhere to any special safety rules. You just need to be careful and careful when working with attachments.

According to technical characteristics

Each device has individual characteristics. expensive models have high power, and budget options are often not able to drill holes of sufficient depth. But the tools also have common characteristics that are inherent in most popular models.

Technical characteristics of devices:

  • Screwdriver. Models for private use most often have a torque of 16 Nm and a rotation speed of 600 rpm. Professional tools boast 130 Nm and 1300 rpm. There are several types of batteries. Nickel cadmium can be charged and discharged fully up to a thousand times. Lithium-ion does not have a memory factor, so it can be easily recharged at any time. There is also a nickel-metal hybrid battery. Its capacity is enough for 500 full charges, but using the tool at low temperatures will not work. Also, the screwdriver can have two types of chuck: key (or cam) and keyless, with one or two couplings.
  • Drill. Classic instruments have a power of 0.6 kW, as well as the ability to adjust the speed. The device has a chuck, as well as a wheel for setting the number of revolutions and a mode switch. Electronic controls and an accessory holder are also often present. To protect the mechanism from breakage and unscrewing the screws, there is a reverse. Its location allows the function to be operated with the finger of the operating hand.

The specified information indicates that the speed of the drill is much higher than that of a screwdriver. Therefore, with its help, you can quickly complete large volumes of work.

Definition

To find the differences between a drill and a screwdriver, you need to consider them in detail. These tools have external similarities, but they also have a huge number of structural and functional differences. The principle of operation is also different. In the article we will figure out what is the difference between a screwdriver and a drill.

Drill

A drill is a hand-held electrical device made in the shape of a pistol.

It is used for drilling holes in workpieces made of wood, metal, brick, plastic or concrete (reinforced concrete structures).

Using Power or Electric Drill as Electric Screwdriver

Most often, a drill is used during construction work or renovation of premises in an industrial or home environment.

Modern instrument models have additional functionality. For example, they can be used to grind a surface, use it as an angle grinder or a construction mixer.

The drill design consists of the following elements:

difference, drill, screwdriver
  • Body made of plastic or aluminum with rubberized handle and additional handle;
  • Collector motor with rotor, starter, armature and brushes;
  • Keyless chuck (used to hold the bit);
  • Start button, which is fixed in a certain position during long-term work;
  • Speed ​​control knob (it should be adjusted in accordance with the material being processed);
  • Power cord for plugging into an outlet;
  • Metal stop (made in the form of a rod, it is necessary to control the depth of the holes);
  • LED illumination for precision.

Before starting the tasks, set the depth gauge to the desired position and adjust the speed. This is done depending on the structure of the material (the harder the workpiece, the less revolutions are required).

Then you need to take the tool by the handle and press the start button. Be sure to direct the nozzle along the same axis that should be at the hole in the material. Changing the angle is prohibited. From the spindle, the torsion is transmitted to the gearbox, which allows the drill to enter the prepared surface. Most drills have a fairly high speed, so all work should be done carefully.

Important! It is recommended to wear protective goggles when working with the drill. Otherwise, small particles of construction dust may enter the eyes and damage vision.

Comparison

To find the differences between the tools, a comparative analysis should be carried out. You can evaluate the characteristics of devices and the types of work that can be performed using them. Only after that the master will be able to determine which tool will be best for him.

By type of work and purpose

With the help of a drill and a screwdriver, tasks of a different plan are performed. Their differences are as follows:

  • The screwdriver is designed for mounting or dismounting bolts, screws, nuts and other threaded hardware. The main distinguishing feature of the tool is the ability to adjust the torque. This helps to deepen the screws to the desired position in the work surface. The screw head will not go into the wall, but will remain flush with it. In addition, in some modern models, the function of grinding and drilling holes is provided when using additional equipment. Of course, performing side tasks with a screwdriver will be less effective than with specialized equipment.
  • The drill was invented for making holes in various surfaces (wood, metal, plastic, concrete). It differs from a screwdriver in that the main indicator of performance is the speed of rotation. This tool is also capable of performing additional functions: sanding, cutting metal or wood parts. It can be used as a drill, but it should be done carefully. There is no screwing depth limiter in the design of the device, so it is easy to rip off the splines or push the hardware too deep into the surface.

DRILL VS. DRIVER (What’s The Difference?!! Cordless Drill Vs. Impact DriverCOMPARISON)

Important! To perform some types of work, it is enough to use one of the tools. However, if there is no experience in the construction industry, it is better to stock up on all the devices, otherwise the end result will be disappointing.

A drill and a screwdriver have physical similarities, but their design and functionality are different. If the main task that a person plans to perform after purchasing a tool is tightening self-tapping screws, then you just need to choose a screwdriver. If he needs a tool as a tool for drilling holes, then it would be better to opt for a drill.

Definition

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 needed 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, that is, in harder surfaces.

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, they make a hole using a special drill (the main purpose of the 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.

Comparison

We have already found out that these power tools perform completely different tasks. But the main differences do not end there:

  • The rotation 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 precautions. 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 has already been noted above that the drill can be turned on both normal and percussion mode. Screw gun is regulated only by rotation speed, no more.

What is the difference between a wrench and a screwdriver: 3 main criteria

In some everyday situations, it is quite difficult to get by with a wrench. Then devices come to the rescue that help to assemble and disassemble threaded devices. Some of these are a screwdriver and a wrench. They have one task. help when working with fasteners. but also a lot of differences. We propose to consider the main differences between the devices, find out which is more convenient to use, and how you can upgrade an old screwdriver to a nutrunner.

An impact wrench is a mechanical tool for screwing in and out nuts and bolts. You cannot do without it when you need to unscrew a rusted nut in hard-to-reach places, and a simple wrench is powerless. The impact wrench can be confused with a drill. but an experienced owner will see the difference: the attachment installed in the holder. It is this nozzle that compresses the nut and holds it while the engine twists it in or unscrews it.

Tip: DeWalt DW292 is considered a convenient option. the model consumes 710 watts of power.

Screwdriver. a device for screwing and unscrewing screws, screws, self-tapping screws and other fasteners. Its peculiarity. work at different speeds. expands the range of possibilities. The device drives screws, drills, has an impact function.

Tip: Bosch has established itself as a market leader in this niche too. Especially popular are the models Bosch GSR 6-45 TE, Bosch GSR 14.4-2-LI Plus.

A wrench, unlike a screwdriver, is considered a more professional tool. According to the method of application, the mechanism for nuts can be: gasoline, pneumatic, hydraulic and work from the mains. It is designed for screwing in or out bolts or nuts. Unlike a screwdriver, a chuck is not attached to the nutrunner. A rod with a nut head is installed in its place.

The second difference. in tightening power, here the impact wrench has an advantage. With him you can “master” any crafts.

Another difference lies in the volume and weight of the mechanisms, for example, not every person can lift some wrenches. Also, screwdrivers are able to regulate their work process, while another representative of mechanics does not have this opportunity. A nutrunner copes with complex tasks no faster than a screwdriver, which creates a lot of noise during operation. this fact is the key difference. In such a situation, equipped with a 3-speed gearbox, the DeWalt DCF895M2 screwdriver can replace any nut tightening device in light tasks.

In terms of operational capabilities, the nut mechanism has serious limitations. It is good to use drills when drilling. So, for soft wood, it is not necessary to use a professional mechanism, you can get by with the BlackDecker EPC12CAB screwdriving tool.

It may also be interesting: How to choose a drill

Which is better wrench or screwdriver?

Given the many functions of a screwdriver, it performs a wider range of work, which is what wins over a nutrunner. In many cases, it replaces the nut device, performs the simple work of a wrench. The screwdriver works even more accurately: the tangential impact of a professional wrench, although it works quickly, but the self-tapping screws do not withstand the stress and can fly out of the building material.

Tip: From the outside, the nut mechanism looks like a conventional drill, and its holder is equipped with an extension attachment.

The impact wrench becomes indispensable during large construction works, when working with cars, ships, airplanes and other units. A device for screwing in self-tapping screws and screws is often used at home for furniture repair. Since such a mechanism is free of mains power, the use of the impact wrench is.

How to convert a screwdriver to a wrench?

Consider how to convert an unusable screwdriver into a new nutrunner. For such a design you will need:

  • Adapter set.
  • Device battery.
  • Control indicator.
  • Button for wrench.

Tip: Store the devices in a case, so the chance of breakage if dropped is reduced to a minimum. It is important to remember that attachments for mechanisms are very fragile and require careful maintenance.

For the device, you need to set the horn for the brakes. Then you need to connect and solder all the connectors of the indicators. If you connect the components correctly, you get a screwdriver. Watch your voltage. the battery is difficult to tolerate. The assembly of parts will take no more than 20 minutes; you can also convert the device to its original state. Such a device will be able to screw in the screws, however, for this you need to put a suitable nozzle.

In summary, it is not necessary to buy new home appliances. Practical expert advice will help you build your wrench. At home, it can be easily replaced with a screwdriver. For more serious construction, the impact wrench is indispensable. We hope our material has helped to understand the main differences between devices for screws and nuts.

What is the difference between a drill and a screwdriver? Learning to comprehend the intricacies of repair

When replenishing their set of tools, people are often interested in how a drill differs from a screwdriver, and whether it is possible to replace one tool in work with another. However, first of all, there is a question about the expediency and necessity of such replacements. I must say that the desire to save a certain amount of money is rarely successfully combined with the desire to make your work easier. Of course, on occasion, a mixer from an ordinary drill can be built. But, as a rule, such know-how is used only when absolutely necessary.

A simple example: you can, of course, pull out a nail from the wall with pliers, but the more likely result will be biting off its head. And with pliers it is faster and more convenient to do it. With the same pliers, you can try and drive in a nail. However, you will most likely bend it. And the hammer will complete the task in a matter of seconds. And these are the simplest, most primitive tools! What can we say about more technological equipment.

Proven by the masters: every tool must have a rather limited scope of application for which it is intended. And today we will leave the invention of the wooden bicycle to amateur beginners.

How a drill differs from a screwdriver can be listed according to completely different parameters. We propose to analyze the following characteristics in order to understand these differences, and, accordingly, find out the aspects of using the compared tools in repair and construction.

This is first of all: it is completely different for a drill and a screwdriver.

The drill was originally invented to make holes in a wide variety of surfaces. Over time, the scope of its application has expanded greatly. Now the tool can be used to mix concreting and adhesive mortars (albeit not on a too large scale), to remove roughness by grinding. you just need to change the nozzles. And a great many of them have been invented in this instrument.!

Also, modern drills are equipped with a mechanism that allows you to switch them to impact mode (impact drill) in order to cope with particularly durable materials. concrete or stone. But the essence remains the same: the drill is primarily needed for drilling.

Yes, it happens that it is also used for screwing self-tapping screws. Unscrupulous builders especially like to carry out such a use of a drill. However, often fasteners enter at an angle, expands the hole when screwing in (as a result of which it does not hold well). in general, a modern illustration of hammering a nail with pliers.

The tasks performed by a screwdriver are inherent in its very name. It is designed for screwing in and removing fasteners with threads (self-tapping screws, screws of various lengths and sizes). We can say that this is an electric screwdriver. And it is not the tip of the tool that is fundamentally important in the design of the screwdriver. this way, you can simply adapt a well-thought-out drill to the drill, which is held in the slots on the screw head.

The main thing in a screwdriver is a locking mechanism that instantly stops rotation when the maximum resistance of the material is reached. This is observed when the screwed-in object rests on a harder material, or when its cap is completely hidden in the surface of the part being connected. Such protection prevents both the failure of the tool and the breakage of fasteners or partial destruction of the surface where the screw is screwed. Twisting into different materials requires different efforts, therefore the screwdriver is equipped with a regulator with which this effect is dosed.

I must say, a screwdriver can partly replace the drill itself and even drill a hole in not too strong material. However, this will take much more time than using a drill. Manufacturers insist not to use a screwdriver in this direction due to the high risk of breakage.

They may not seem as significant compared to the difference in purpose, but they exist and you need to know them in order to use both tools competently.

  • Rotational speed. For a drill, even not equipped with a percussion mechanism, it is much higher. This is due to the fact that, in principle, it was invented for destruction, overcoming obstacles. The rotation speed contributes to a faster solution of the task. For screwing in fasteners, fast rotation is only an obstacle, since it reduces the accuracy of work.
  • Inertial moment. In a screwdriver, it is practically absent. When the button is released, the chuck stops immediately. When the drill is turned off, the drill continues to rotate for some time, which is often fraught with injury, especially for a not too experienced beginner user.
  • The weight. The drill is much heavier than its counterpart. the weight also helps to quickly deal with the obstacle. The small weight of the screwdriver provides more precise, jewelery work.
  • Safety precautions. When working with a drill, the precautions are more serious: the high speed of rotation causes particles of the material in which the hole is made to spray out. Therefore, safety glasses are required. The screwdriver is practically safe both because of the slower twisting of the chuck, and because it pursues other, non-destructive goals.
  • Modes of operation. Modern drills can switch from drilling to hammering, that is, they are of two types. With a screwdriver, only the direction of rotation is switched plus the force is regulated. That is, it can only work in one mode. Some manufacturers supply screwdrivers with an impact mechanism. Experts do not advise buying such hybrids: the second role, aimed at destruction, they still play weaker than impact drills, and the accuracy of the main task (screwing in) is lost.

Having figured out for himself how the drill differs from the screwdriver, the zealous owner will select a set of tools based on his needs. If minor repairs in the house happen infrequently, you can purchase a hybrid. drill-driver with impact function: you will rarely have to use all the possibilities, so why spend money on highly specialized tools. True, you have to sacrifice screwing accuracy.

With constant work, both a drill and a screwdriver are bought (by the way, this is the most common choice). And if you also have to chisel more than once in a decade, then a perforator is also purchased for them, designed specifically for the destruction of complex materials that the drill will no longer be able to handle.

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 are only of small diameters, and not everywhere are on sale.

Thus, for this tool, we conclude that it can only be purchased for tightening self-tapping screws. At the same time, we remember that it is tied to the network, which means that it will not work autonomously with it.

It is most convenient to use this unit in any assembly workshop, where work is carried out at one working place to screw in self-tapping screws or screws.

Drill

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.

Often, when screwing a self-tapping screw with a drill, its cap can drown unnecessarily in the material, or the slots of the bit scroll in the cap, which can cause them to be ripped off.

Therefore, here you have to rely only on your hands and head.

According to 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 twisting with a screwdriver.

What is the difference between a drill and a screwdriver?

Hello everyone! 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).

Picture 1

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 battery-powered) or simply screwdrivers.

In order not to get confused, in this article we will assign the following names to each unit:

  • the tool from Figure 1 I will call the screwdriver
  • from figure 2. drill
  • from Figures 3 and 4. drill driver.
READ  Drill Heads In Work

At the same time, I note that the difficulties of choice arise precisely between the last two types, since everything seems to be so clear with an ordinary screwdriver. But I’ll describe all three devices early.

Drill driver

This tool is versatile. They can be drilled and screwed, without fear of ruining 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 stays in place, safe and sound.

In addition, the drill driver 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 drill with a 400 W motor will have the same torque as a 700-800 W drill. However, the dimensions will be smaller.

Cordless Screwdriver or Cordless Drill?

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-screwdriver 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 in jobs that require a high chuck rotation speed. This is, for example, drilling a brick when the work takes place in the hammer mode. And although there is an impact mechanism on some models of screwdrivers, due to the low speed, it is not very effective.

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, a drill driver is also poorly suited for such work.

Separately, it should be said about cordless drills and screwdrivers. 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 just lie idle;
  • the inability to immediately start work if it suddenly turned 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. see you soon.!

Is it worth buying a tool

Sometimes buying a tool may be impractical, for the reason that a screwdriver is simply not suitable for performing certain jobs. Despite the convenience and mobility of drills with batteries, you need to be aware of their disadvantages:

  • The weight of the device is quite significant due to the fact that the battery is installed in the body of the tool. It will not be very convenient for working with a canopy.
  • In the process of discharging the battery, the power and quality of work decrease. Such a deficiency causes severe discomfort.
  • When the battery is discharged, you will have to wait until it is recharged, and if a household screwdriver is used in the work, then this is at least 3-4 hours.
  • Over time, the battery loses its power and charge, so sooner or later you will need to purchase a new charger.

We definitely recommend to look

However, if you take into account the peculiarities of the operation of a cordless drill, you can purchase a screwdriver that will fully meet the stated requirements and will work for a long time without being connected to the electrical network. In order to choose a suitable model, the following factors should be remembered:

  • Through the autonomous mode, the preparation time of the tool for work depends on the voltage, which ranges from 9 V to 24. This value forms the power on which the weight of the battery itself depends.
  • The battery will retain its charge longer if the current-to-time ratio is highest.
  • All types of batteries have their own characteristics. Perhaps the best option would be nickel. metal hydride batteries. Although they can withstand fewer charges than lithium, they do not have hazardous substances. However, they are small in size.

For convenience, it is better to choose a model with a separate charging mode. In this case, you do not need to wait for the drill to charge. While one battery is charging, the other will work. Batteries are easy enough to change as needed.

Tool selection by parameters

The first factor that influences when choosing a tool is the purpose and frequency of its use. It is not at all necessary to buy a professional expensive tool if its purpose is to screw something on several times a year. If a cordless drill is necessary for regular use, it is better to look at the professional models with the greatest power and number of functions. Another difference between the usual ones is the operating time of the charger.

In order to choose the right screwdriver, you should pay attention to the possible configuration and parameters of the tool. A drill with a battery can be of different configurations, most often, it is a tool with a large number of attachments. Tools with separate attachments are more convenient to use. Of the parameters by which the selection will be made, the following should be noted:

What is a drill and screwdriver?

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.

Tool manufacturer

In order to choose a screwdriver, one should not forget that the choice of the tool manufacturer plays an important role. Naturally, a household drill and a professional drill will differ in price and quality, but it is clearly not worth overpaying for a regular screwdriver. You can choose a household screwdriver from Bosch, Hitachi or Hammer.

Most professional drills are manufactured by Dewait. The company’s products are distinguished by a decent value for money. When buying, you should take into account the fact that the cost of a tool, as a rule, doubles depending on the manufacturer’s popularity. Also, you should pay attention to the list of possible functions. most of them are rarely useful in work, and the price of the tool is greatly increased.

Torque and rotation speed

Maximum torque is a kind of blocking that is used to avoid overheating of the tool and its failure. Such a system works at 5-10 Nm, which is quite sufficient to carry out the insertion of the mountings and ensure the safety of the battery.

When choosing a drill, pay attention to the operation of the engine under maximum load, it will also not be superfluous to track how well the tool holds speed.

The rotational speed of the drill for screwing in the screw should be equal to five hundred revolutions per minute. For comfortable work, you need a screwdriver with a rotation speed of 1300 rpm. At the same time, it is necessary to understand that too high a speed of work may be needed only for drilling the most hard materials. Also, you should pay attention to the presence of a reverse motion. If the screwdriver does not have one, the drill may get stuck.

What is the difference between a drill and a 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, they make a hole using a special drill (the main purpose of the 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.

The difference between a screwdriver and a drill

First, a little help: how does a screwdriver differ from a drill? Many citizens think that if with a battery, then a screwdriver, if with a plug, then a drill. In principle, most screwdrivers do operate on rechargeable batteries, but not all, there are also those that operate on the mains. So this argument is bypassed. And the main difference is that when the button is released, the screwdriver instantly stops rotation, while the drill chuck spins for quite a long time by inertia, simultaneously killing the slots on the screw or even tearing off its (screw) head. The overrun brake is responsible for the instant stop, which is usually not available on a drill.

Also on the body of the screwdriver near the chuck there is a special regulator ring, commonly referred to as a force or power regulator. The correct term is torque regulator. If you have already had a chance to hold a screwdriver in your hands, then you know that if you set this regulator to a minimum, then even just in the GVL you will not be able to tighten the screw, the cartridge will stop rotating, and the screwdriver will crackle. This means that the release clutch has worked, and this, in turn, means that the set torque is clearly insufficient for the task at hand and it would be necessary to add by twisting the ring (clutch). The number of steps for adjusting the torque is different for different companies and even for different models, there is no standard in this case. At the same time, most screwdrivers have a set maximum, usually indicated not by a number, but by the image of the drill. Since most screwdrivers have a more complete name sounds like a cordless drill / screwdriver. this means that by switching the clutch to the drill bit, the tool can be used as a drill, the release clutch does not work in this case. True, the coasting brake will work anyway. Well, it is also desirable for common sense to work. if even in your screwdriver you can turn off the release clutch, but according to the passport, the tool is weak, with a torque of no more than 20 Nm, then you should not load a bit on concrete into it and prepare a place for the socket. most likely you just burn the anchor or erase the gears in the planetary gear.

Nevertheless, there are screwdrivers with which you can not only tighten self-tapping screws, but also drill wood, gypsum plasterboard, gypsum plasterboard, and so on using a crown or a feather. as I said, there are many models, everyone can do different things. And in this section we will try to understand them.

Well, let’s start with one of the most popular brands called Makita (Makita), in the recent past Japanese, but now it is clear, mainly Chinese, which, however, in this case is not so scary.

Battery capacity

The power of any tool is determined by the power of the engine. Therefore, before choosing a drill, you should find out the characteristics of the capacity of its battery and its voltage. The latter is determined by the number of power supplies that are installed in the unit. Accordingly, the greater their tension, the more powerful the instrument itself. A characteristic such as the mass of a screwdriver also depends on the voltage. Before purchasing one, you should decide if you really need a massive 36V drill. For household chores, drills with a voltage of 12 and 14.4 V are quite suitable.

Battery capacity is measured in ampere-hours. It is this characteristic that affects the duration of the screwdriver. Household tools have a battery capacity of 1.2. 1.5 amps. hours. For professional drills, the battery capacity is 2 to 3 amperes. hours.
