What is the difference between an impact electric screwdriver and a non-impact

At such a price, it is difficult to find very powerful models on the market, mainly their limit is 400 watts. Problems can also arise with the drilling diameter, you can count on a maximum of 2.5 cm (for wood). There will hardly be many speeds here either, one or two is the ceiling. But otherwise it is a very good tool for non-professional use.

The main parameters of the battery and the tool itself

The main parameter that characterizes the operation of a screwdriver is the voltage of the battery, which, in turn, determines the power of the electric motor and the torque. For household models, the difference in voltage between screwdrivers is small. on average, it is in the range of 10.8-14.4 V. productive options designed for constant use can be equipped with batteries of 24-36 volts.

The battery voltage of an electric screwdriver depends on the type of battery. you can answer what the difference is, knowing what metals were used to make it. For nickel-cadmium batteries, large in size with a similar capacity, the value of the indicator is a multiple of 1.2 V (this is exactly the voltage for one element of which the battery pack is made up), for lithium-ion batteries. 3.6 V.

Among other, equally important characteristics, one can note:

torque, the value of which can become one of the main answers to the question of what the voltage of the battery of an electric screwdriver affects. According to this characteristic, it is possible to determine both the diameter and the length of the screw or self-tapping screw. Large fasteners, as well as drilling deep and wide holes and hard materials, require a serious torque value. Torque. 12-15 Nm (maximum up to 30 Nm) for home models, 30 Nm for professional models

The parameter is important, pay attention to it. If the maximum speed is below 1000 rpm, it will be convenient to use the tool to tighten screws and drill soft materials (wood, metal, plastic). If you are going to drill metal, choose models with rpm above 1500 rpm

They will have two speeds: the first is for fasteners, the second is for drilling. For serial work (installation of drywall sheets, clapboard cladding), choose corded screwdrivers with a depth gauge. For work at home, I will fit both network and battery models, so choose what you like best.

There are two types of screwdriver torque. starting (larger in magnitude and required to start the device into operation) and constant, that is, working. The parameter value for modern equipment models can be adjusted. to find out how many modes can be selected for a particular device, you can find out in the documentation available for it. over, tools with a pulsed mode of operation (turning on the rotating part in jerks) have more screwing capabilities. allowing you to periodically increase the torque, they can screw in a larger screw.

In addition to the voltage of the electric screwdriver and its power, the capacity of the battery should also be evaluated. The characteristic is measured in ampere-hours or milliampere-hours. The higher the indicator, the longer the screwdriver can work without recharging.

The average battery capacity of the household model is 1300 mAh, which is enough for 2-3 hours of operation. Professional equipment requires more time to complete the work. and a master who uses a screwdriver for a whole working day should purchase a model with a battery already from 1.5-2.0 Ah and more.

Since the screwdriver is powered by electricity, it cannot be exaggerated that it can be either a mains or a battery. The former is suitable for renovating a small house or daily work in a well-equipped workshop, because it is easier and you do not need to constantly remember to charge the battery.

However, it is a type of battery that is an alternative solution during construction or for outdoor use when the workplace does not require functional outlets.

The main differences from the hammer drill

These devices differ primarily in functionality. The main function of the hammer drill is hammering, and rotation is just one of the functions. It can work in three modes at once:

  • Rotation.
  • Rotation with impact work.
  • Impact work without rotation.

Rock drills use a pneumatic mechanism (like jackhammers) or electromagnetic coils. This explains the high power, you can not only punch holes in the walls, but also make grooves in brick and concrete for wiring, sockets and switches.

The main disadvantage of the device is its large mass, so the work requires more physical strength than with an impact drill, which is lighter than it.

The essential difference between the hammer drill is in the fastening of the working tool. Any electric drill has a cam chuck for the cylindrical shape of the tool, while in the hammer drill the tool is attached by means of special grooves. Therefore, you cannot use drills with a cylindrical shank on a hammer drill.

Important! There is a special device. a cam chuck, which is inserted into the hammer drill. Only with the help of such an adapter can you work on this tool with ordinary drills.

How the impact drill works

This drill is designed for drilling holes in metal, wood, plastic and durable materials. in brick and concrete. From the electric motor through the gearbox, the rotation is transmitted to the chuck, in which the cutting tool (drill) is fixed. For hard materials, bricks and concrete, one rotation is not enough to make a hole.

It differs from a conventional drill by the presence of a ratchet mechanism, which gives the tool reciprocating movements. blows, it is they that allow you to drill holes in solid material.

Important! Conventional drills are not suitable for such work; you must use a tool with a victorious tip. The impact mode in such a power tool can be turned on and off.

At idle, the striking mechanism does not work, it only starts when you press the tool

The impact mode in such a power tool can be turned on and off. At idle, the striking mechanism does not work, it only starts when you press the tool.

How to choose?

When choosing a specific model of an electric 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 the battery life, and the weight of the device, because a capacious battery always weighs quite a lot.

Another point is the choice of the type of battery: today, the most common lithium-ion models, but nickel-cadmium are also found. The former are good with a small mass with a significant capacity, they allow charging at any time, but they are more expensive than the main competitor and can wear out quickly at low temperatures. The advantages of the nickel-cadmium solution completely eliminate the disadvantages of the lithium-ion version. such a battery is cheaper and not afraid of frost, but it is heavy and environmentally hazardous, and most importantly, it must be completely discharged and then fully charged, otherwise the “memory effect” will provoke rapid wear of the carrier.

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 unreasonably expensive.

Chucks of an electric screwdriver, in which replaceable nozzles are attached, are quick-clamping and key. The first can be organized in different ways, but its advantage is that it can be serviced with bare hands. The key cartridge has a characteristic rim; a special key is needed to maintain it, which is not always convenient.

Since we are talking about the cartridge, an important criterion is the maximum diameter of its opening. the larger it is, the more different nozzles can be used.

Maximum torque is a measure of how hard the nozzle will rotate. This indicator does not always directly depend on the power of the motor, sometimes it can be increased due to the gearbox, but it is always desirable that the maximum torque be quite high. Models with stepless torque control are in priority, since they are more sparing for fasteners and surfaces that are drilled.

Additional functions

Reverse function, i.e. backstop, allows you to unscrew tight screws and pull out stuck drills. To turn the reverse on or off, there is a button located usually on the handle, which is very convenient. The essence of the reverse is to change the positive and negative fields in the electric motor.

You can choose a model with functions that will greatly facilitate the work and reduce the time allotted for repairs. For example, a drill / screwdriver with a tape for feeding self-tapping screws. A tape with self-tapping screws is attached to the bottom of the case, which are fed automatically.

There is also a magnetic holder under the chuck, a backlight and an indicator showing the battery charge.

Bosch GSB 18-2-LI

The previous models of the series proved to be excellent in everyday life, and the new device became another work on mistakes, where the manufacturer, as they say, took into account and deducted a lot. Yes, an electric screwdriver cannot compare with the capabilities and functionality of more noble similar devices from the premium segment, but it finds its buyer in cost and quality.

The model has a maximum torque of 63 Newton meters. In shock mode, this is quite enough for drilling bricks, frozen cement and other not particularly picky surfaces, but on high-quality concrete the “kid” stumbles, and seriously.

Indicative

Distinctive features

When deciding whether to choose a shock or shockless model of an electric screwdriver, first you need to figure out how they differ.

difference, impact, electric, screwdriver

Many consumers who have managed to evaluate the operation 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.

  • Directional impacts increase the torque of the percussion tool to a range of 80-250 N / m, making it possible to break through the most difficult obstacles. It is significant that in the process there is even no need to firmly press the case against the wall. the tool bites into it even without significant pressing.
  • Without the need for constant physical effort applied to the tool, the wrist and hand of the master are much less tired, which allows you to increase the same productivity.
  • Considering that even a solid wall is not able to successfully withstand the onslaught of such a tool, it usually does not deform the fasteners, which will allow it to be removed without additional efforts in the future. over, many models also provide for the reverse function of removing old fasteners from the walls, and even the fact that, due to long-term operation, it has experienced strong deformation.
  • an electric screwdriver works not only with bolts, but also with nuts, in each case achieving the most tight tightening. A “smart” car usually automatically switches from shockless mode to shock mode when it senses that the nut has become tighter at a certain moment.

Unfortunately, this solution also has certain drawbacks, which may never allow it to completely supplant unstressed models. Thus, an impressive twisting speed is observed only in the shockless mode; when switching to impacts, it significantly decreases.

Chucks for such a tool are not suitable for any. you need strictly hex. Most models do not have a limiting sleeve, so the degree of 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.

Operating rules

The use of an electric impact screwdriver will be safe and as effective as possible only if it is done correctly. Obviously, the first tip is to read the instructions before use, but there are other reasonable tips for use.

For example, if possible, do not expose the equipment to maximum torque, because many fragile materials with a treated surface can simply be torn from this, and you will ruin the workpiece. In addition, working at maximum speeds up tool wear, not to mention the fact that in this mode you need to hold it tighter, otherwise there may even be a possibility of injury.

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 electric screwdriver mode is to screw in fasteners, when used, on the contrary, efficiency decreases, but the risk of injury increases.

It is completely unacceptable to change the settings on the fly, with a rotating chuck. this can break the unit.

Always wear protective goggles and gloves, especially with fragile materials. When drilling walls, make sure there are no electrical wires in advance. Remember that the time of 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 an electric screwdriver, then it is better not to try to drill anything with it. such experiments often end with a burnt out engine.

When using a cordless electric screwdriver in cold weather, be prepared for the fact that a battery of any type, especially a lithium-ion battery, will discharge much faster, therefore you need to charge it more often.

What is it and what is it for?

An electric 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 actual rotation, but also with the help of directional blows. The latter usually do not have a permanent character. the corresponding mode is turned on at the request of the operator or automatically if the drill runs into an obstacle of particular hardness. In a sense, it’s a little jackhammer.

An electric impact screwdriver is a more complex and “smart” device in itself, therefore a certain versatility should not be surprising. This means that the tool, as a rule, is fully compatible with various attachments, thanks to which the scope of its potential application significantly expands. instead of a drill, you can attach, for example, a hole saw or a mixing attachment.

A distinction should be made between an electric impact screwdriver and a similar drill. The latter, being focused on making holes, assumes a longitudinal direction of impacts, while an electric screwdriver strikes as if longitudinally, due to which it significantly increases the torque.

It is logical that such a tool is somewhat more expensive than non-impact models, but its purchase is often justified even at home. the external, load-bearing walls of multi-storey buildings are usually distinguished by the highest strength, which can only be overcome by an electric shock screwdriver.

The device is also appreciated by professionals who drill walls or various parts every day. according to them, for all its assertiveness, the drill of an electric 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 reality 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 an electric 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 “electric 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 electric screwdriver is powered by electricity, it is impossible not to clarify that it can be both mains and battery. The first is good for minor home repairs or daily work in a well-equipped workshop, because it is lighter, and the master does not need to constantly remember to charge the battery.

However, it is the battery version that is the uncontested solution during the construction process or for use on the street, when the working site does not imply the presence of functioning outlets.

Impact screwdrivers: what is and how they differ from shockless?

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. to screw a screw) into the wall. Without this elementary skill, you will not be able to hang a shelf, decorate a room with a picture, or install a curtain rod.

An electric electric screwdriver is called upon to cope with this task faster and without unnecessary effort, and the electric impact screwdriver is especially often praised, but not everyone understands what it is and why.

How to choose?

Batteries can produce different voltages, but for periodic household work, you can choose models with a value in the range of 12-18 V.

At 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 unreasonably expensive.

The last, but very important criterion for choosing a tool is its weight. Unfortunately, it is impossible to create a lightweight, yet powerful and multifunctional device, therefore it is necessary to decide which is more important: lightness or performance. Keep in mind that with constant daily work, the first factor may be much more important.

Care Tips

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.

Difference between Drill Drivers & Impact Drivers

The gearbox of an electric screwdriver may require periodic lubrication, an indicator that such a moment has already come is a characteristic unpleasant sound and a tight movement of the chuck when trying to rotate it by hand.

In the next video you will find an overview of impact and non-impact screwdrivers: AEG BS12CS vs BSB12C2.

Advantages and Disadvantages of Impact Tools

For many buyers who are faced with the choice of which drill or impact wrench to choose, the question arises, how is the impact electric screwdriver superior to the impactless model?

  • The increased torque allows the technician to apply significantly less effort when working with the tool, without pressing on the body itself. For most models, the values ​​of this indicator are in the range from 80 to 250 N / m.
  • The possibility of using not only for self-tapping screws, but also for working with nuts. With the free running of the product, the electric screwdriver works in the standard mode, when resistance occurs and the smooth movement of the nut on the thread is reduced, the mode automatically switches to the impact mode.
  • Since there is no need to apply excessive force to tighten the bolts and screws, the caps will not deform. The power of the tool is also enough for the reverse action. unscrewing the parts that have changed their original shape or rusted;
  • The ease of use of the tool also helps relieve stress on the user’s hand and wrist.

Limitations and disadvantages of impact-producing screwdrivers include a decrease in the tightening speed during impact mode, since the actions of the tool concentrate on the turning moment and on the quality of work. Also, only hex chucks can be used. The degrees of tightening must be controlled independently, since there is no limiting clutch. There is also an increased noise level when working at high speed.

What is the difference between an impact electric screwdriver and a non-impact

an electric screwdriver is an indispensable tool in everyday life for every man. With its help, it will not be difficult to attach a shelf or hang pictures. The screwdriver is specially designed to tighten and unscrew screws, nuts or self-tapping screws. The electrical appliance market is so diverse that it is difficult to navigate and choose the right tool. The best option today is an electric impact screwdriver. What are its differences from the usual, what are the characteristics and features?

Advantages of the Electric Impact Screwdriver

By purchasing this power tool, you greatly facilitate your work at home or in the workshop, and on a production scale it is simply irreplaceable.

Let’s consider the main advantages of the tool:

Impact drill electric screwdriver HITACH

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

  • it completely replaces the screwdriver;
  • using an electric shock screwdriver, you can tighten or unscrew any nuts and screws;
  • if necessary, drill wood or even metal or concrete;
  • the device is much more compact and easier to use than, for example, a drill;
  • this type of power tool is equipped with an adjustable clutch, which allows you to limit the torque and avoid damage to the fasteners;
  • there is no need for strong pressure when tightening self-tapping screws or screws, which allows you to save their caps and then it will not be difficult to unscrew them if the need arises;
  • high wear resistance of the tool;
  • possibility of installation in hard-to-reach places, due to the compactness of the device.

Benefits of Impact Screwdrivers (Impact Wrenches)

  • High torque! For most cordless models, the torque range is between 80 and 250 Nm!
  • Convenient for tightening nuts. At low loads, the tool operates in a shock-free mode with continuous force (quickly tightens the nut along a free thread), and with an increase in resistance, it switches to an impact mode (tightening with a high torque).
  • There is no need to apply a large pressing force to the tool when tightening screws and self-tapping screws, thereby saving the caps from “licking”. Also, with its help, you can unscrew those screws and self-tapping screws, the caps of which have already begun to bully.
  • Reduces torsional stress on the operator’s wrist.

Differences between a traditional drill and an electric impact screwdriver

For many craftsmen who choose tools for home use or for work, the question arises, what is the difference between the not yet well-known electric impact-type screwdriver and the usual standard electric drill. With a similar appearance, the main difference is the principle of operation:

  • In the first case, the tool has an impact mechanism that drives the drill, while increasing the torque;
  • A standard electric drill is based on a two-stage gearbox.

This distinction is starting to show itself, giving an advantage to the percussion type tool when working on hard and particularly difficult surfaces. When the drill senses resistance, a series of powerful and fast impacts are sent that multiply the torque and tighten the fastener much easier.

It is also worth distinguishing between an electric impact screwdriver and a drill. With the same principle of operation, they have a different direction of impact. For a drill, this is longitudinal, and for an electric screwdriver, it is perpendicular to the direction of rotation. The process of action of the tool is most clearly represented as small blows with a wrench while tightening the nut.

Characteristics of impact screwdrivers

Before choosing any power tool, you should familiarize yourself with its characteristics. Regarding impact screwdrivers, he

Cordless impact drill electric screwdriver Bosch GSB

  • weight: 1-1.3 kg;
  • power: 230-300 W;
  • idle, frequency per minute: 0-3600;
  • the number of beats per minute up to 3200;
  • has double electrical insulation;
  • equipped with a reverse mechanism;
  • many models have a light bulb to illuminate the work surface.

Applications

The fundamental difference between percussion models and standard ones is their compatibility with other devices. You can use a hole saw in parallel, and also replace the functions of a conventional drill for drilling holes using special attachments.

Higher torque with less pressure on the tool by the operator.

Many people often ask the question, what are the advantages and differences of an electric impact screwdriver (nutrunner) from a conventional one and who needs this tool and why? And here it is important not to confuse an impact drill with an electric impact screwdriver, which is sometimes more correctly called a wrench. An electric impact screwdriver or impact wrench has a tangential impact (in a plane perpendicular to the axis of rotation), i.e. the effort to tighten screws or nuts is not applied continuously, but by a high-frequency series of small blows, as if you put an open-end wrench on the nut and started tapping it with a hammer. The total applied force is calculated as the sum of the efforts of these blows per unit of time.

Based on this, you can immediately highlight the advantages and disadvantages of tools of this class.

The cost

Impact screwdrivers are slightly more expensive than conventional ones. This fact is due to the multifunctionality of the device. Also, the cost varies depending on the brand of the manufacturer, additional options that the power tool can be equipped with, for example, a charge indicator, a lamp for illuminating the work surface, or two batteries are provided in the package. All these nuances can affect the cost.

The price range varies from 4,500 to 30,000 rubles. depending on the manufacturer and characteristics of the electric screwdriver. Its average You can find a tool costing 5-6 thousand, but in terms of characteristics it will be inferior.

It all depends on what purpose you are pursuing in operation, if you need an electric screwdriver for domestic purposes and for rare use, a model with a below average price policy will suffice. If you purchase a power tool for a workshop or production, it is better to give preference to models from a more expensive range, their durability will be higher.

As for the manufacturers, their choice is wide, each of them has established itself in the tool market. The most popular brands of screwdrivers: Makita, Bosch, Hitachi, DeWALT.

By giving preference to an impact screwdriver, you get a reliable assistant in everyday life or at work. This power tool will make your work easier and will please you with ease of use.

In the arsenal of each owner there is a tool that allows you to tighten or unscrew a screw, a self-tapping screw, to make minor home repairs, assemble furniture, drill a wall for a new picture. Automatic electric drills greatly simplify the process, allowing you to drill almost any surface without much effort and unnecessary debris.

Now on the market there is a huge selection of tools from different manufacturers, models, wired and mobile, for various surfaces and with a different principle of operation. According to experts, among the colossal variety of drills, the most productive, convenient, versatile and multifunctional is the electric impact screwdriver.
