First, all screwdrivers are divided by the method of power into:
It’s very simple: rechargeable battery does not weigh much, quickly charges and does not “tie” you to the socket.
In addition to battery powered screwdrivers, the mains powered screwdrivers are also very popular. And here the question immediately arises, what is the best choice for an electric chain screwdriver?
The corded power tool is powered directly from the mains. Among the advantages of corded tools, is that they will operate for as long as you need without recharging.
For example, customers often ask how to choose an electric screwdriver for the home. We will answer this question in the next paragraph.

What is the best impact wrench??
The choice of an electric screwdriver begins with knowing its characteristics. Knowing the application field of the tool, you can intelligently choose the right option. What features to look for?
Quality and reliability. There is no sense in a disposable tool, so we recommend buying a device with a maximum service life.
Class. The tool is divided into 2 classes: household and professional. Professional. more powerful and more expensive. Domestic. simpler and cheaper.
Power. The higher this index, the harder material the electric screwdriver will be able to handle. Household models have a maximum power rating of 550 watts.
torque. Measured in Newton meters, it characterizes the force exerted on the fasteners. The higher the value, the longer screws can be driven. For home use 10-15 Nm is enough, for professional work torque up to 40 Nm is required.
Torque control. Adjustment allows you to change the force the electric screwdriver exerts on the fastener. The higher the amount of force (the number on the dial), the deeper into the material the screw will go. For drilling, the electric screwdriver has to be switched to the mode that was specifically designed for this application.
Reversible power stroke. A tool with a reverse stroke is more convenient to use. In the past, only professional models had this function; today, almost all screwdrivers have it.
Ergonomic features. A good tool should not only be functional, but also comfortable. And so you need to pay attention to its weight, the shape of the handle, the presence of anti-vibration pads, the location of the buttons and controls.

Type of chuck. This affects how quickly you can change tool bits and how well they lock in place.
There are several types of chucks for different purposes that can be mounted on an electric screwdriver. The three most common chucks:
Quick-action chuck. no need for a special wrench to tighten the chuck and which requires constant attention. One of the most reliable and durable chuck types.
Self-clamping chuck. can be locked without a wrench. No muscle power is needed to tighten it. A slight twist of the sliding sleeve is enough. Needed by craftsmen who frequently change bits.
Bit chuck. a special chuck for bits. This product is usually used for inserting a bit and is only used for loosening (screwing in) threaded fasteners (bolts, nuts, screws, self-tapping screws, etc.). п.).
Additional features. The simpler the tool, the lower the price. Extra options add comfort but increase cost.

- Reverse rotation. Reverse rotation mode is used to unscrew fasteners and remove the drill bit easily from deep holes.
- Impact mechanism. The so-called impact drill enables drilling even in brick and concrete.
- Backlighting. Backlighting is a useful feature for those who need to work in poor lighting conditions.
- Speed adjustment. Stepless adjustment allows for precise setting of the operating mode.

Some tips before you buy
First, make a list of the tasks you will perform. The power and functionality of the electric screwdriver that will suit you best depend on it.

Among the screwdrivers for the home you can find models that do not require complex maintenance during operation.
Professional devices are more capacious, have expanded functionality, increased battery capacity. Some professional screwdrivers can be used for drilling holes in non-hard surfaces.
Types of Screwdrivers
Screwdrivers, first of all, are divided by the type of power source. Cordless tool is convenient for its independence from the wires, which will become a nuisance in a confined space (the cord can cling to the furniture, get tangled in the legs, kinked, twisted). This kind of electric screwdriver often comes with a drill function, which is a plus when repairing or finishing work. Battery power is sufficient for occasional work of several hours a day, and modern chargers allow you to recharge it in an hour. A corded tool, on the other hand, is to be considered for series use. These screwdrivers work with a constant power, which is often more than that of cordless, and it will weigh less, and cost less.
Another thing to look out for. is the use of the tool as a drill. Not every electric screwdriver has a drilling function. The mains models almost all lack it.
Consider another classification. the division of the tool into a professional and a household tool. Technical characteristics play an important role here. A professional electric screwdriver is built to last. It does not overheat under prolonged load, shows better performance results. The reason for this is that such a tool is made of durable materials, each manufacturer seeks to develop its own special combination of alloys and components to improve the properties of the product.
Overview of the most popular brands of this type of power tools
To simplify the final choice of model, it is necessary to specify the most popular brands, under the logos of which modern power tools are produced. Durability and cost depend in part on this, so the choice of a particular manufacturer should not be neglected.

Chuck and bit selection in an electric screwdriver
There are three types of chucks in the mentioned power tools:
The quick-action chuck is more popular because of its convenience and practicality. The drill bit or nozzle can be changed in just a few seconds. The second most popular chuck. hexagonal. Standard bits with hexagonal end are used for it. They are easily inserted into the design and fixed inside the chuck.
Bits are always included in the scope of delivery of the screwdriver. The keyed version, on the other hand, is less common because it requires a special key, which also comes with the kit. This format was relevant a few years ago. The inside diameter of the chuck shows the maximum size of the bit or bit that can be inserted in it. Optimal parameter. 7-10 millimeters. This value is most often mentioned in the list of specifications, so pay attention to it when selecting it as well.
It is also worth paying attention to the screwdrivers with a backlight, because it is very convenient and useful advantage.
