Which is better screwdriver or impact. disadvantages

What is the difference between a screwdriver and a gaykovert?

Gaikovert is often called a tool for professional work, and a screwdriver. A household tool. Several of their key differences can be distinguished: the dimensions of the Gaykowert are often more than that of a screwdriver. Their weight also differs. The Gaikovert is heavier, but it has a good positive difference in power.

Impact (from the word blow) is a pulse screw.Vert or Gaykowert. In a professional environment, it is customary to conventionally call impacts with a Hex ¼ head (hexagon). Screw verters, and with a head a square ½ (under the heads for nuts). Gaikovert. In fact, any pneumo or battery Gaykowert, This Impact.

How to choose a professional screwdriver

The essence of the visible differences in professional screwdrivers and domestic ones lies in the characteristics that provide quick work and user comfort. To select such a tool, pay attention to the following parameters:

  • The power of twisting. Measured in Newton by a meter. For professional use, it should be from 30 nm and above. Then you can unscrew the old fasteners or screw a long self.Tapping screw.
  • Power or voltage. In network devices of a professional type, the indicator should start from 400 watts. For battery screws, the battery voltage is important, which is 18 V and higher.
  • Type of battery. Nicd (nickel-cadmium) is cheaper, but there is a memory effect. Before charging it, you will need to completely devastate the container, otherwise the battery will “think” that the existing level is zero, and this will reduce the volume of the resulting energy and autonomy time. Li-Ion (lithium-ion) battery is more expensive, but it can be placed on charging at any time. When choosing a screwdriver for professional activity, preference should be given to models with this type of battery.
  • Battery capacity. The time of autonomy depends on it. If there is a socket at the workplace, then two batteries with a capacity of 1.2-2.0 A/h ensure the continuous operation of the screwdriver throughout the day (while one works, the second is charged). If the object is not connected to 220 V, then choose batteries with a capacity of 3.0 a/h and above.
  • The presence of a quick.And.Sound cartridge. With professional use, the master often has to alternate the installation of fasteners with a drilling material. If the screwdriver is equipped with a fast.Packed cartridge, then you will not need a drill. Otherwise, you will have to buy and carry two tools with you.
  • Important little things. Professionals are divided that a function such as diode backlight is useful to them. Inside the cabinet or unlit room, this will simplify the drilling and installation of fasteners without an additional flashlight. The bit holder will help not only quickly change the cross nozzle to a flat, but also reliably fix a couple of screws so that they are at hand in a hard.To.Reach place.

Important! Since you will use a professional tool every day and a volume of hours, experts advise personally hold it in their hands before buying, and not order the goods via the Internet. After all, it can be very difficult or more than it seems in the photo.

Bright impact, why European builders do not use screwdrivers, but buy impacts

Do it yourself

Yes, yes, I was not mistaken, we will only talk about builders who have at least 75 mm screws in the work. Who makes the roof with a “black grouse”, self.Tapping screws with a drill, etc.D. Recently, home masters began to switch to this level.

An experienced builder knows that if you buy Shura for 3-4 thousand rubles and accompany it to the object, there will be enough about two or three roofs. This is if you make a roof of 250 square meters, but not in a hurry with conclusions, it all depends on what kind of tool you came across and what hands did you work.

This is my second blow in the workshop, now I will explain why not another screwdriver.

Dewalt DCF809D2T. Despite the high torque (190 nm, 2800 rpm), such a tool can be tightened by any fasteners, from “seed” to “black grouse”. Smooth start due to constant electronics, which really feels the power of pressing the button.

Safety, many people know that large screws or hazel grouse for 150 mm need to be twisted with two hands so that the brush does not twist. Working at a height in this mode is insanely inconvenient.

The blow solves this problem, it can be held with one hand and perform complex tasks.

Time saving. Due to high speed of self.Tapping screws can be tightened several times faster. And if you need to disassemble the structure, then there is generally a fairy tale.

But you need to understand that at first the blow works like a regular screwdriver, as soon as the load increases, the impact mode is turned on.

Well, the most important advantage, the tool is compact, convenient and fast, which means that the work is performed much faster and is spent less effort.

So, we have listed many advantages of this tool, and now about the shortcomings. There is only one minus, high cost, the price of this model is almost 20 thousand rubles. But if you are a professional in your field or want children to work with your tool, then the choice is obvious.

Common mistakes when you choose a screwdriver

The greater the capacity and power of the tool, the faster the hands will get tired. Yes, and you have to pay for them more expensive. When you plan to build a house or a lot of repairs, it is better to buy a pair of medium-capacity batteries for 12-18 watts. At 18-24 watts they take when they will have to work with large nozzles.

IMPORTANT! To large volumes of work, it makes sense to take a model that is quickly charged. She will charge the battery in 1-2 hours. For comparison, let’s say that the charger of low power will make full charging in 12 hours.

Screwdrivers that have a drilling function cannot be replaced in the private sector and in the country. But in apartments from concrete from them there is no benefit. In order to work in the garage, a model that has a replaceable cartridge and nozzles is more suitable.

IMPORTANT! Autonomy is preferable to power when we talk about work in nature. If we combine a wired drill and a wireless screwdriver, then an ordinary user can bury 99 percent of his needs. A professional in repair work can not do without a battery screwdriver.

These models have a powerful engine with forced cooling and smooth start. Buying brownless models costs more. In everyday life they will never pay off.

So that it is not a pity for the money spent on the purchase of the tool, and get the maximum benefit, the screwdriver needs to be chosen under any specific task. This may be, in particular, the assembly of furniture, small household repairs, construction work.

IMPORTANT! Battery models have many advantages. However, there are cases when it is easier to stretch the wire than to run and charge the battery. Models that have a brilliant engine developed for professionals. And they are too expensive for domestic repair.

Features and advantages of unstressed screwdriver

The design of this tool is more simple and reliable. Since in his case there are no stable alternating loads, cartridges and rotors are much greater than wear resistance.

Unstressed screwdrivers are cheaper than shock models. In addition, they have less weight and dimensions, and are also distinguished by the ability to work for a long time without recharging.

If you are going to work with wood and soft brickwork, screwing and twisting fasteners under an insignificant load, you should choose an unstressed screwdriver.

When trying to perform complex tasks, difficulties arise. The main disadvantage of the tool of this type is the inability to drill unlucky materials of high density (concrete, stone).

The equipment will not allow you to work with damaged fasteners, since the working head will scroll, without performing the expected job.

What does the impulse screwdriver mean?

This is a small device in shape and weight, which is externally similar to the traditional screwdriver. The main difference is the presence impulse operating mode. Due to this, the power of fasteners does not occur smoothly, but intermittently with characteristic measured jerks (tangential blows).

It is also worth distinguishing Shock screwdriver and drill. With the same principle of work, they have a different direction of strikes. For a drill. This is longitudinal, but for screwdriver. Perpendicular to the direction of rotation. The most clearly the process of action of the tool is to imagine how minor shots with a key while twisting the nut.

How to choose a screwdriver. Types, characteristics and of screwdrivers

The screwdriver owes its existence to electric engines. Their work is based on the principle of electromagnetic induction. He reveals the formation of current in a closed circuit during magnetic field jumps.

The discoverer of the phenomenon is considered Michael Faradei. He announced his research in 1831, and in 1834 Boris Jacobi was invented the first electric motor. They thought of connecting it with a screwdriver only in the 20th century.

Processing is explainable. Waiting for the inventions of the screws familiar to us. The Robertson screw became their prototype. Peter Robertson invented him in 1907. The novelty was transformed into a screw with the Crusade in 1934 with the help of Henry Philipps.

You Need This Tool. Episode 4 | Impact Screw Driver

In the middle of the century, attempts began to create screwdrivers. Low.Power batteries were brought. Supensed created only in the 90s. Then success came to screwdrivers. For home They are indispensable, at least for modern. Why? Let’s understand.

The purpose of the screwdriver

Manual tool, designed for twisting and unscrewing fasteners. Most often work with self.Tapping screws. This variety of screws is characterized by a large step in the thread and is covered with a strengthening composition.

What is a screwdriver Impact?

Impact (from the word blow) is an impulse screwwoman or gaykowert. In a professional environment, it is customary to conditionally call impacts with a Hex ¼ head (hexagon). With screw verters, and with the head a square ½ (under the heads for nuts). With a gaykovert. In fact, any pneumo or battery gaycote is impact.

A screwdriver with a pulsed regime. A compact construction tool for performing a wide range of tasks. Unlike classic models, it has increased power and torque.

Is it possible to use a screwdriver as a drill?

The tasks of the screwdriver. Twisting and unscrewing self.Tapping screws, screws. If the drilling mode is not involved, then the screwdriver as the drill will work. In addition to the battery tools, the Drill of the Network Squad is popular, which, although it is now found on sale less often, has no less advantages.

The spinning moment of the screwdriver is 8-10nm, the speed of rotation of the shaft is usually about 500 rpm. Drill shuruvret demonstrates much more impressive characteristics. The twisting moment is 10-40 nm, the speed of rotation is 1500 rpm. Therefore, in order to make holes, it is better to use a drill-spray.

What is the difference between the electrical office from a screwdriver

The electrical office is the simplest electrical tool. In fact, it is a regular screwdriver (performs only the functions of unscrewing and twisting), only equipped with an electric motor. People who rarely come across repairs do not know the fundamental differences between a screwdriver and electrical appropriation, but there are quite a lot of them, and often both of these devices are called the same term, but this is incorrect.

An important difference between the electrical office from a screwdriver is its small dimensions and weight. This allows you to easily transfer it, and if necessary, just put the right thing in the jacket

What is an impact? Why is it needed with a screwdriver?

What is an impact? Why is it needed with a screwdriver?

In this video I tell and show what an impact is.Impact (from the word blow) is an impulse screwwoman or gaykowert.In a professional environment, it is customary to conditionally call impacts with a Hex ¼ head (hexagon). With screw verters, and with the head a square ½ (under the heads for nuts). With a gaykovert. In fact, any pneumo or battery gaycote is impact.

which, better, screwdriver, impact, disadvantages

Impacts are fundamentally different from screwdrivers of their device. Large spinning moments are achieved due to the force of inertia and shock impulse. This inertia and the impulse, unlike screwdrivers, occur not due to a lowering gearbox, but due to the rotation of the flywheel, untwisted by the engine and when compressing the spring, which bears the spindle along the tangent to the axis of the rotation. You can more simply imagine the principle of action as unscrewing the nut with a chisel and a hammer.The main drawback of the impacts is a loud noise from the blows of the flywheel during operation.The main advantage in the absence of “reverse traction” from the tool during wrapping powerful fasteners. That is, in the absence of return on the handle of the tool. At the same time, impacts having approximately equal dimensions and weight relative to a class screw, can develop 3-4 times larger peak torque.In addition to noise, one of the disadvantages of impacts is the inability to drill metals with drill diameters over 8-9mm, the inability to work with crowns on solid materials such as stone, porcelain tiles, etc.P. Ineffective drilling stone, brick and concrete with ordinary drill with winning tips.Obviously, each of these tools has its own strengths and weaknesses. Therefore, when there are both of these tools in the set, they complement each other, expanding the use of the application together and generally reaching much better characteristics than any type of tool, even a higher class, power and cost. For example, a combo Kit of 12 Volta series can cost as one powerful 18 volts drill and can at the same time provide work with fasteners of the same level, but with much smaller dimensions and weight. This greatly facilitates the work. Especially in cases where people hold the tool in their hands or on the belt throughout the work shift. Over, it often happens that you need to simultaneously drill and twist. Constantly changing the bats/drills in a screwdriver, this is more tedious than having two compact tools separately for drilling and wrap.Therefore, in recent years, most of the batteries of the battery instrument began to offer in their assortment such paired sets “Drill-shuruvret Impact” and have become very widespread and popular among professionals.

Network or battery

Each owner of a wired screwdriver periodically thinks about buying a battery version to perform work on the roof, in the garden and other places without a constant source of electricity.

Equipment

The easiest option is only one screwdriver, and even without a case. In the average price segment, the manufacturer can be disgusted for a suitcase, a couple of batteries and a set of bit.

Nozzles

There are several dozen nozzles for various tasks, five types of scissors alone:

There is still a nozzle for protection against dust, fast installation, drilling of ice, grinding, rivets, etc.D.

It is a pity, they do not go in the kit, except that an angular one at 900 and a gaykowert in some models.

which, better, screwdriver, impact, disadvantages

There are many of them, and they are different, you need to learn how to distinguish PZ and pH.

There should be a marking with the corresponding designation on a box with screws. PH0, PH1 and PH2.3.4. CREART AND THE SIT of the Standard of 1937, the figure means size.

Pz. Crusade of Zackes of the 1966 Standard. The angle of sharpening decreased by 50, from 550 to 500, the sting became even over the entire thickness. Due to the new faces, a strong connection of the bit with a slot at high speeds was implemented and the load on the tool was reduced.

For a powerful high.Speed tool, it is better to take PZ screws, if only consumables with a pH hat are available, if possible, reduce the speed of the twist and press the bat tightly so that it does not jump out from the slots.

TOP-3 best models

A wide range of such products is presented on the construction tools market. We selected 3 of the most successful models:

  • Metabo BS 18 LTX. The screwdriver of German production. It has a fast.And.Packed cartridge, power from the battery with a capacity of 18 in.
