Rating of the TOP 15 best corded and corded drills and screwdrivers

Why do you need a cordless impact screwdriver?

Compared to other rotating machines, the cordless impact screwdriver has the following advantages:

• high maximum torque;
• reduces the load on the hand of the master;
• does not require increased clamping force;
• has the ability to drill holes;
• automatic transition from normal to shock mode;
• long operating time without recharging.

The disadvantages include the following:

• lack of manual torque control;
• the need to use special bits;
• drills holes in fragile substrates, such as wood.

An impact driver is a versatile tool for any DIYer, often called an impact drill/driver. However, when purchasing it, it is not so easy to make the right choice. Before you pay money and take the screwdriver home, you need to analyze the device according to the following criteria:

• maximum operating time without connecting to the network;
• Li-Ion battery type;
• tool power, which varies from 24 to 36 V;
• torque of at least 70 Nm;
• comfortable feeling;
• weight no more than 1 kg;
• reputable brand (Bosch, Makita, Metabo).

Why do you need an impact driver?

An impact driver is designed to effectively drill into concrete walls to drive in screws and then install other fasteners. Thanks to rotation and targeted blows, the device instantly makes a hole, eliminating the need for the user to use multiple tools and spend a lot of time on work.

The unit is compatible with various attachments, which means that its scope of application expands significantly. By attaching a hole saw instead of a drill, the owner can use the device to cut various elements and structures.

Impact cordless screwdriver: what is it?

A screwdriver is a convenient electric tool that allows you to quickly unscrew and tighten bolts, nuts and screws. Modern screwdrivers are most often equipped with a battery, which makes it possible to use the device over the entire area without being tied to the length of the cord. These screwdrivers have the following advantages:

• the device is lightweight, making it easy to hold it in one hand;
• low rotation speed, which allows you to unscrew the fasteners and not “lick” its notches;
• the ability to regulate torque - for more convenient screwing in fasteners of different sizes;
• presence of reverse motion - for unscrewing fastening parts.

The main disadvantages of cordless screwdrivers boil down to one thing. This is low power - up to 20 V for unscrewing a bolt or self-tapping screw firmly seated in the base. An impact driver was developed to solve this problem. This tool has more power - up to 36 V. There are both mains and battery versions. The principle of operation of such a device is that when, for example, a self-tapping screw jams in a tree, the electrical device automatically puts a shock load on the fastener, loosening it. Moreover, this does not happen along the axis of the screw, but along the axis of rotation. The device stops, suddenly gives an instantaneous maximum rotation speed to the fastener and lowers it to normal speed. The cycle of such operations is repeated until the screw is unscrewed. Typically, an impact driver will quickly solve this problem.

How is an impact screwdriver different from a non-impact screwdriver?

Unlike simplified non-impact devices, impact screwdrivers stand out due to the presence of such features as:

• versatility of use;
• fast and efficient drilling;
• high power;
• availability of additional attachments included;
• inability to deform the caps;
• ease of operation and maintenance.

Despite all the advantages of impact models, such devices are also more expensive than non-impact screwdrivers. At the same time, the battery life of impact structures is significantly shorter, and the level of noise emitted is higher.

Differences between a traditional drill and an impact driver

Many craftsmen who choose tools for home use or for work are faced with the question of what is the difference between a not yet well-known impact-type screwdriver and an ordinary standard electric drill. With a similar appearance, the main difference is the operating principle:

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

This difference begins to manifest itself, giving an advantage to the impact type tool when working with hard and particularly difficult surfaces. When the drill feels resistance, a series of powerful and fast blows are sent, which significantly increases the torque and tightening the fastener becomes much easier.

It is also worth distinguishing between an impact driver and a drill. Although they operate on the same principle, they have different blow directions. For a drill it is longitudinal, and for a screwdriver it is perpendicular to the direction of rotation. The most obvious way to imagine the process of the tool is as small blows with a wrench while tightening a nut.

Rating of popular models

Which one is better to choose? To purchase the best impact screwdriver model, experts recommend that inexperienced users consider a number of popular devices offered by well-known manufacturers. At the same time, it is worth studying in advance the main technical characteristics, pros and cons of both battery-powered devices and network devices.

Ask a Question

When choosing an impact screwdriver, you should consider the following:

• The universal device is perfect for carrying out minor repairs at home;
• for professional work, it is better to purchase a device from the well-known Kress brand, the BOSCH brand or the trusted company Makita;
• important characteristics are the type and diameter of the cartridge, as well as the maximum number of strikes per minute of operation;
• It is necessary to pay attention to the number of operating speeds, as well as the weight of the unit;
• A protective lock on the power button will help make working with the device safer.

Advantages and disadvantages of percussion type instruments

For many buyers who are faced with the choice of which drill or impact driver to choose, the question arises as to how an impact driver is superior to a non-impact model.

• The increased torque allows the technician to apply significantly less effort when working with the tool, without putting pressure on the body itself. For most models, the values ​​of this indicator range from 80 to 250 N/m.
• Can be used not only for self-tapping screws, but also for working with nuts. When the product moves freely, the screwdriver operates in standard mode; when resistance occurs and the free movement of the nut along the thread decreases, the mode automatically switches to impact mode.
• Since there is no need to make excessive efforts to tighten the bolts and screws, the caps are not deformed. The power of the tool is also sufficient for the reverse action - unscrewing components that have modified their original shape or have rusted;
• The ease of use of the tool also helps relieve stress from the user's hand and wrist.

The limitations and disadvantages of impact-producing screwdrivers include a decrease in the twisting speed during the impact mode, since the actions of the tool are concentrated on the turning moment and the quality of work. You can also only use hex chucks. The degree of twisting must be controlled independently, since there is no limit coupling. There is also an increased noise level when working at intensive speeds.

What is better to choose

There is no such thing as a universal tool. For fast and high-quality work, you need to choose the right power tool, from a non-impact drill to a hammer drill. If drilling with infrequent impact work is necessary, we choose an impact device. For large volumes of work on brick and concrete, it is better to purchase a hammer drill.

The difference in power tools is not small. Of course, to perform quality work, it is advisable for a master to have all three types.

Useful articles, news and reviews on our Yandex Zen channel

Minor home renovations, nailing shelves and installing pictures require drilling, screwing or unscrewing. To do this job yourself and quickly, you need the right tool. For everyday needs, it is impractical to have many different tools, but there certainly should be one. All that remains is to make a purchasing decision: drill or screwdriver?

The difference between a drill and a screwdriver

The tools drill, screw in screws, and punch holes in concrete, stone, and brick planes with equal success. But the existing differences in their mechanisms do not allow us to turn a blind eye to the features of the first and second home assistant. Take, for example, the ratchet of a screwdriver, which a drill lacks. The addition allows you to adjust the force with which screws, screws and self-tapping screws are screwed in. Comfortable? And how!

It is not easy to understand which is better, a drill or a screwdriver. It’s worth starting from what a particular tool is needed for. Corded drills and screwdrivers are faster, have greater power, weight and drilling diameter in different materials. Yes, they are more efficient in their work, but they are definitely not more convenient than a lightweight tool weighing 1.2 kg.

For greater practicality when working without a mains connection, use cordless tools. If you take cordless screwdrivers and compare them with drills, they will turn out to be more popular, cheaper and more widespread. Their “weak point” is power. A corded drill, judging by the impressive indicator of this parameter, works much more efficiently.

How to choose a drill

So what to choose: drill or screwdriver?

1. How often do you plan to work with the tool? 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 wood. 18- and 20-volt cordless drills can handle almost any screwdriving task. Even a cheap drill is more powerful and durable than a corded 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 lower RPMs has much better control. Therefore, if we are talking about irregular small jobs, then it is better to choose a screwdriver. It is also more suitable if the work consists solely of screwing in self-tapping screws, screws and screws.

2. Work in places without electricity. To make a hole or two, it is better to use a cordless screwdriver than a drill with a similar power supply. 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.

3. Level of comfort when working. Cordless drills gain more power at the cost of added weight. Some professional cordless drills weigh up to 3 kg, which makes long-term use tiring. Less powerful household drills are lighter, but even they cannot compete in lightness with electric screwdrivers, which weigh less than half a kilo. If the heavy weight and presence of a wire interfere with the work of the drill, then it is better to purchase a cordless screwdriver. It works productively with wood, plastic, metal, and accurately screws fasteners.

How to choose the right cordless screwdriver

Universal drills and screwdrivers

In order not to think about your 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 once you turn on the ratchet to jam the drill joint, you’ll find yourself with a drill. If you purchase an impact attachment, it will perform even more tasks.

Drills and screwdrivers are divided into mains-powered and battery-powered based on their power source.

Price difference

Cost also plays a big role when choosing the perfect tool for your home. Drills are not only practical and powerful, but also quite affordable. You can choose a particularly optimal option from the household assortment. Their initial cost is within the capabilities of every owner.

Tip: Tools powered by the mains are not as convenient to use (more weight, presence of wires), but they quickly cope with work on wood, metal and concrete.

A special feature of screwdrivers is that they work with self-tapping screws, screws and screws. They are not very suitable for drilling. Cordless 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 network counterpart of decent quality.

For small amounts of work, it is better to purchase a screwdriver. If you are renovating your home and often need to make holes in different materials and work with fasteners at the same time, then a drill is better. This tool is supported by its low cost with normal characteristics - everything you need for household purposes.

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

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

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

2. How often do you plan to use the tool (often or occasionally). For minor, occasional 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 is possible with an impact drill and a universal drill-driver.

3. What will be the working conditions (will there be access to power supplies). Drills and screwdrivers come in corded and corded versions. If you work on a site without electricity, then you need a cordless tool. It is important to remember that corded drills and screwdrivers are much more powerful.

As you can see, making a choice turned out to be not so difficult - the main thing is to ask the right questions and give clear answers to them! This video review will further help you assess the situation.
