How to properly care for a screwdriver?

Regardless of whether you are the proud owner of a screwdriver or just dream of it, it is worth remembering that it can achieve its best characteristics only with proper use and proper care. Which cordless screwdriver is better, its price will tell. Of course, the higher priced models are made of materials that are more durable than the cheaper ones. But even the most inexpensive screwdriver will serve you for many years if you take good care of it.

Advice! Before starting to work with the screwdriver, read the instructions. Nowadays, the variety of devices is so great that the operating rules can differ significantly depending on which manufacturer’s screwdriver you purchased.

Always pay close attention to the battery, because it is he who is the heart of the screwdriver. For example, lithium-ion batteries cannot be brought to full discharge, as this significantly affects the further operation of the device. But the nickel-cadmium battery, on the contrary, requires a complete discharge.

For your power tool to last for a very long time, you need to take care of it.

As for the body of the device, in no case should you wipe it with heavily moistened sponges or even submerge it under running water, because this way it can absolutely fail. After completing any work with a screwdriver, wipe it with a dry or minimally damp sponge, and then wipe it dry. It must be stored in a specially designated place where the device will be protected from moisture and other external factors, for example, in a dry pantry.

Cordless screwdriver: which one is better and how to make the right choice?

In order to make the right choice and understand which brand’s cordless screwdriver is better, you should pay attention to the main characteristics.

Cordless screwdriver is one of the most sought-after electric tools

But many simply do not know how to do it correctly, and therefore face the problem of a difficult choice. In order for your purchase to be truly profitable, you should focus on a few characteristics:

  • Since the main feature of this screwdriver is the battery. then you should pay attention to it first. Here, characteristics such as capacitance and voltage are important. After all, the power of the device is closely related to the magnitude of the voltage. As for the capacity, it is this that affects the performance time of the screwdriver. Also, the material from which it is made plays an important role in the device. The lithium-ion device benefits significantly in terms of compactness, but requires special attention to charging. A nickel-cadmium battery is heavier, but requires recharging only after it is completely discharged.

The battery is the main feature of the screwdriver

  • Torque is another key characteristic of a screwdriver. After all, it depends on what the maximum torque is, how large the screw is able to tighten the given device.

It depends on the torque whether a screwdriver can only screw a self-tapping screw into a tree or it will easily gnaw through concrete

  • Speed ​​is the first thing buyers think about when purchasing a screwdriver. The required number of revolutions depends on exactly where you want to use the purchased device. For example, to drill a hole in a wall. you will need about 1400 rpm, and in order to secure the screw, you need much less rpm. 400–600 rpm. Many screwdrivers have several modes, which greatly simplifies their work.

A sharp angle between the “barrel” and the handle can cause calluses between the thumb and forefinger.

Obtuse screwdrivers fit very comfortably in the hand

The origin of the screwdriver

In order to understand how beneficial and useful a particular device can be for you, it is important to know what led to its appearance and what purpose its inventor pursued. Times are rapidly changing, and progress inexorably erases from the memory of mankind the names of those who once made life easier for people by inventing a previously unthinkable invention. It is for this reason that it is difficult to remember who exactly deserves to bear the laurels of the discoverer of the cordless screwdriver. Obviously, the first battery was invented, but in those distant times, no one imagined how this very battery would change people’s lives. And then there could be no question of connecting it with a screwdriver.

Comparison of cordless and cordless screwdrivers

The cordless screwdriver is definitely one of the essential helpers for household chores. Thanks to the variety of attachments and modes, you can not only tighten screws, but also make holes in the required places. Modern devices of this type are becoming more and more ergonomic. They are easy to use, and in recent years they have significantly lost in volume and weight, which allows absolutely everyone to use the tool.

Many are familiar with the problem of driving nails in an apartment in a panel house. It’s almost impossible with a hammer, but with a drill or screwdriver, you only need a couple of minutes to hang a shelf or painting. In summary, we can say that the cordless screwdriver is the choice of those who value their strength and time.

Criteria for choosing a cordless screwdriver

To choose a quality screwdriver, it is not enough to pay attention only to the price, appearance and comfort in the hand. It is necessary to additionally evaluate a lot of characteristics. Those who do not trust the consultants can independently study the technical passport of the device they like. It describes the main parameters and capabilities. What is important when buying a cordless screwdriver and which device is better for the house from inexpensive ones is described in detail in the following sections.

Voltage and other parameters

For an ordinary buyer of a screwdriver, it is enough to know:

  • for household appliances, the voltage ranges from 10-14 V;
  • for professional, the indicator should be more. from 18 V. Some instruments boast a level of 36 V.

The next characteristic is power. The parameter informs the user about the speed of the device. It is logical that the higher the power, the faster the screw will be screwed in. But you should not overdo it, for household purposes and do-it-yourself in-line repairs, a 500-700 W model is quite enough.

In order not to send the device for charging every half hour of operation, you should pay close attention to the battery. Modern screwdrivers use:

  • Lithium-ion batteries are not subject to self-discharge, the most common. They can be charged up to 3000 times, and at any stage and discharge level.
  • Nickel-cadmium. are not afraid of cold, they work efficiently at subzero temperatures. However, there is a small drawback. self-discharge. You need to store such a battery with 0% charge in order to save capacity to the maximum.
  • Nickel-Metal Hybrid batteries are eco-friendly batteries found in some European brands. These batteries are compact and lightweight, but they are frost-resistant.

When comparing battery specifications, it’s also worth looking at capacity. The autonomy of the device and the number of possible recharges depend on it. Over time, the capacity decreases, this must also be taken into account.

Torque

The numbers in the characteristic show with what force the screwdriver twists the self-tapping screw or how much force is required to overcome the load during drilling. What is the practical use of knowing the parameter? The diameter and length of the bolt to be screwed in depends on the torque. The higher the indicator, the longer and thicker the screws can be used in work without fear of failures or breakdowns. For example, at 40 N / m, it will be possible to freely “drive” a self-tapping screw 10 cm long into the tree.

In small household models, the torque is from 10 to 30 N / m, but the indicator can be adjusted by adjusting to the nozzle. For adjustment, a limiter is provided on the screwdriver body. a ring that goes immediately after the chuck. The user can coordinate the effort for a specific screw by scrolling the limiter. Result: as soon as the self-tapping screw is tightened to the desired level, the chuck will stop, although the motor will work at the same time.

Interesting: the stop not only helps to tighten the bolts, preventing excessive “sinking” into the material, but also protects the tool from wear.

Rotation frequency

To choose the perfect device for specific purposes, it is worth paying attention to the number of revolutions. The manufacturer calls this parameter speed or rotational speed. It is adjusted by pressing the “trigger”. the harder you press, the greater the speed. In addition, the frequency shows whether the tool will be able to screw the screw into a dense material and what is the approximate diameter of the hole if the screwdriver replaces the drill.

If the customer is confident that the device will only be used for tightening screws and bolts, 500 rpm is more than enough. Screwdrivers acting as drills operate at 1200 rpm.

Nuance: there are models with 1, 2 and 3 speeds on the market, where one is for self-tapping screws, the second is for drilling small holes, the third is for working with metal or other durable raw materials.

Emphasis on the manufacturer

The hackneyed truth is a brand beyond competition. Yes, branded tools are more expensive, but they have a quality guarantee and service centers for repairs, and the screwdrivers themselves are made of durable components.

Quite good screwdrivers with a removable battery are also offered by Varo Kreator, Sparky, Dnipro-M and others.

Tool chucks

Buyers often ask: “How to choose the right screwdriver for the house, focusing on the type of chuck?” The answer is to remember the information and learn to distinguish one type of cartridge from another. There are 3 of them:

  • The key one is that the drill holds in it a device resembling “cams”. the two sides of the chuck are connected with the fastening side to the center and in this way clamp the tool. The chuck nut is tightened with a special wrench that comes with the kit. It takes some time to change the tooling, but the fixation is strong and reliable, which is ideal for working with hard materials.
  • Keyless. one- and two-sleeve. The main difference is that in single-cartridge cartridges, the nozzle is changed with one hand. press the cartridge, remove the rig, put the other. For double clutch, you will have to use both hands, which is already inconvenient.
  • Hexagon. A special “socket” for bits, which are necessarily included in the tool kit with such a chuck.

Looking through the assortment of cordless screwdrivers with different cartridges, it is difficult to answer which one is better. Here, rather, you need to look at the diameter of the hole in the chuck, it depends on it what kind of equipment can be used when working. In household tools, nozzles no more than 1 cm thick are used.

Everything about battery-powered screwdrivers: pros and cons

The main difference between the cordless screwdriver and the network model is the absence of a cord. Autonomy of work and non-attachment to the outlet are the main advantages of a tool with a battery inside.

The advantages of the device also include:

  • Mobility. The tool and the charging battery are in the same housing, no additional elements are needed for operation. It is enough to take the device in hand, and it is already ready to work. Can be moved anywhere.
  • Compactness. As a rule, household autonomous screwdrivers are small in size. This makes the device especially convenient in hard-to-reach places.
  • Versatility. Technique replaces screwdriver and drill.

In practice, a cordless instrument is indispensable in objects without electricity, when it is necessary to frequently move or climb to a height. The device can be operated outdoors or indoors.

The only drawback here is the need to periodically charge the battery. Manufacturers are trying in every possible way to solve this problem, for example, offering 2 batteries with the tool. While one is in the working process, the second restores energy.

    The difference between a drill and a screwdriver

    Tools with equal success drill, screw in screws, beat holes in concrete surfaces, stone, brick. But the existing differences in their mechanisms do not allow us to close our eyes to the features of the first and second home helper. Take at least the screwdriver ratchet, which the drill lacks. The add-on allows you to adjust the force with which screws, screws and screws are screwed in. Conveniently? And how!

    Understanding which is better, a drill or a screwdriver, is not easy. It is worth starting from what this or that tool is needed for. Corded drills and screwdrivers are faster, have more power, weight and drill diameter in different materials. Yes, they are more efficient at work, but definitely not more convenient than a light tool weighing 1.2 kg.

    For more practical work without mains connection, use cordless tools. If you take cordless screwdrivers and compare them to drills, they are more popular, cheaper and more common. Their “weak point”. power. A power drill, judging by the impressive indicator of this parameter, works much more efficiently.

    Universal drills

    In order not to think about the choice for a long time, make a “knight’s move”. The universal tool combines the functionality of both assistants, expanding the range and increasing the efficiency of work. In appearance, it looks more like a screwdriver, but on the ratchet, turn on the jamming mode of the drill connection. and a drill appears in front of you. If you buy an impact attachment, it will do even more tasks.

    Drill-screwdrivers by power supply are divided into mains-powered and battery-powered.

    So choose: drill or screwdriver?

    How often do you plan to use the instrument? Lightweight electric screwdrivers have much less powerful, lower voltage motors than most cordless drills. Therefore, they may not cope with the task if they screw long screws with a gap into hard woods. 18- and 20-volt cordless drills can handle almost any screwdriving task. Even a cheap drill is more powerful and more durable than a cordless screwdriver. Therefore, this toolkit is suitable for working with the hardest building materials. Drilling in walls, installing complex structures in places with electricity. all this can be done with a drill.

    Tip: A screwdriver with less rpm is much better controlled. Therefore, if we are talking about irregular small works, then it is better to choose a screwdriver. Also, it is more suitable if the work consists solely in screwing screws, screws and screws.

    Work in places without electricity. To make a couple of holes, it is better to use a cordless screwdriver than a power drill of the same type. For example, the Bort BAB-10 screwdriver, which is powered by a battery, is more convenient and cheaper. it makes no sense to buy an expensive cordless drill for household use.

    Comfort level at work. The power of cordless drills is increased by the added weight. Some professional cordless drills weigh up to 3 kg, which makes them tiresome for long periods of time. Less powerful household drills are lighter, but even they cannot compete in lightness with electric screwdrivers, which weigh less than a pound. If the heavy weight and the presence of a wire at the drill interfere with work, then it is better to purchase a cordless screwdriver. He works productively with wood, plastic, metal, precisely screwing fasteners.

    Which is better to choose. drill or screwdriver for home: 3 selection criteria

    Minor home repairs, nailing shelves and installing paintings. this requires drilling, twisting or unwinding. To do this job yourself and quickly, you need the right tool. For everyday needs, it is impractical to have a lot of different tools, but there should definitely be one thing. It remains to make a purchase decision: drill or screwdriver?

    Price difference

    Cost also plays a big role in choosing the perfect home tool. Drills are not only practical and powerful, but also quite budgetary. A particularly optimal option can be chosen from the household range. Their initial cost is quite within the power of every owner.

    Tip: Mains-powered tools are not so easy to use (more weight, wires), but they quickly cope with work on wood, metal and concrete.

    Feature of screwdrivers. work with self-tapping screws, screws and screws. They are not very suitable for drilling. Rechargeable models are convenient to use, but their power is enough for short and simple work. The price of such a tool is three times cheaper than its decent quality network counterpart.

    For small volumes of work, it is better to purchase a screwdriver. If the house is being renovated and you often need to make holes in different materials, along the way to work with fasteners, then a drill is better. This tool is supported by its low cost with normal characteristics. all that is needed for domestic purposes.

    Tip: Any tool can be made better with special drills.

    To decide what to buy. a drill or a screwdriver. answer the questions:

    What kind of work are you going to do (you need a hammer drill or you can do something simpler). The more difficult the task, the more powerful the tool is needed: a screwdriver is suitable for screwing in, and for drilling in concrete. drill.

    How often you plan to use the tool (often or from time to time). For minor, rare work with screws and holes, you can use a screwdriver, but for regular work you need a more powerful tool. Long-term work with hard materials under the power of an impact drill and universal drill-screwdriver.

    What will be the working conditions (will there be access to power sources). Drills and screwdrivers are battery and mains. If the work on the site is without electricity, then a cordless tool is needed. It is important to remember that power drills and screwdrivers are much more powerful.

    As you can see, the choice was not so difficult. the main thing is to ask the right questions and give clear answers to them! This video review will help you assess the situation even more.

    Platform is an important detail

    No, not even the most important one. The platform is one of the most important criteria by which it is recommended to select this hand tool. This parameter can be found out if you know the battery voltage. Today there are about 4 main platforms. Every brand that makes electric or cordless tools works with one platform.

    Choosing a platform means finding a compromise between the real weight and power of the device. You will understand which is better to choose a cordless screwdriver.

    We drill, fix, cut threads

    To activate the drilling mode, many devices from reputable brands have a special flip frame. It switches the gearbox operating modes. In drilling mode, the speed is doubled. Also, the torque will be halved. Drilling is used less often, but the presence of such a mode is one tool instead of two. There is also a three-speed cordless screwdriver, which is better at cutting threads with taps. Here there is an opportunity to get even lower rpm, and the torque will be simply huge.

    Ergonomics

    The ease of use of a hand tool is more than just comfort. Many manufacturers of these devices are constantly trying to constantly improve their ergonomics. There are many different body shapes, lining materials. Many devices differ in the distribution of weight, the location of the controls. So, a cordless screwdriver, which is better, you need to choose according to the hand of the master and the type of work that has to be done. It is best to choose a screwdriver that is convenient in every sense, even if you have to pay for it with other characteristics.

    One of the important ergonomic parameters is the angle between the handle axis and the motor axis. Designers, creating, in their opinion, comfortable equipment, sometimes make the handle tilt angle too big back. Because of this, it is not always convenient to use the tool. The hands of the craftsmen are numb or overstrained, and a callus appears between the thumb and forefinger. You need to switch the direction of rotation with one hand, this has to be done quite often. Cordless screwdriver which is better? Reviews will help you decide, but it is best if you yourself hold your choice in your own hands. Also, it will not be superfluous to make sure of the excellent balancing of the selected instrument.

    Choice for the specifics of work

    It may seem that a screwdriver is a versatile tool. In fact this is not true.

    So, for those who assemble furniture, more compact models are suitable. They are convenient in that they can work even in the most inaccessible places, and the effort and torque is enough for a reliable and high-quality assembly. The drilling mode is practically not used here. So, for drilling, a more powerful cordless screwdriver is purchased. Which is better? Makita provides a wide range of professional tools at a very affordable price. Screwdrivers of this company have high performance and are very convenient.

    Also, these tools are used for the installation of plasterboard structures. Here manufacturers offer two-speed models with a large battery. For this type of work, the weight of the tool is very critical. For work on the ceiling, models with one speed are suitable without a chuck based on a collet.

    Power is important in special assembly work. Therefore, they choose a cordless screwdriver, which is better for additional functions. Consumers want the device to replace both a hammer drill and a drill.

    Planetary gearboxes

    These devices use planetary gearboxes. Often three satellites can be found in such designs. The carrier is rigidly attached to the crown, it has a lower gear. If the device is capable of delivering up to 25 Nm of torque, then the gearbox device is predominantly plastic. With a torque of up to 50 Nm, manufacturers allow a plastic case. If it is a powerful tool designed for professional use, the gearbox consists of only metal parts. When choosing a cordless screwdriver, which one is better. not hard to guess. Metal parts have a much higher durability and reliable service life.

    Safety clutch

    This system allows you to adjust the torque. It is not possible to use the device in the same way as with a torque wrench, and the scale is only conditional. However, if manufacturers indicate data on the dependence of efforts on the position of the regulator, then this tool can be taken into account.

    Available platforms

    So, tools operating at a voltage of 18 V are even average. The voltage value allows for good torque up to 100 Nm, and the weight is quite light. At this voltage, most models for professionals are created, as well as some representatives of the amateur group.

    The 24-V platform is used primarily to create the highest quality and most expensive equipment. It is a powerful engine, less sensitivity to overloads, reliability and increased service life. Cordless screwdriver which company is better? It all depends on the needs and the work that will have to be done.

    12 and 14 volt models are a variety of hobbyists.

    Here compactness and lightness have a much higher priority than high power, high performance, and service life. It must be said that often at this tension it is possible to single out some series of tools for professionals from market leaders. If you plan to use this device often and seriously, then this is your choice. professional cordless screwdriver. Which one is best to choose from the entire available variety of models depends on some requirements. But do not flatter yourself too much. Such “bison” as “Bosch” or “Makita” position their devices as equipment for professionals, but any representative on this platform will not be able to screw a 120-mm self-tapping screw into dense wood.
