Corded screwdrivers, unlike models with an autonomous power source, provide, under certain conditions, greater productivity and continuity of work. Below we consider which corded screwdriver is better when carrying out repair and finishing work at home, assembling furniture, etc.

The most important characteristics of a screwdriver

When choosing a screwdriver, attention should be paid to the most important operational parameters of the device. Among them are:

  1. Power. Determines the performance and weight of the power tool. Screwdrivers for domestic use usually have enough power of 450-650 watts.
  2. Torque. Directly determines performance, characterizing the force that the tool provides when rotating the bit. The magnitude of the moment determines the material with which the screwdriver can work, as well as the length and diameter of the fastener.
  3. Reversing mechanism. Its presence allows you to remove fasteners.
  4. Rotational speed, ways to regulate its value. Determine whether the device can be used in various conditions.
  5. Ergonomics – comfortable grip, light weight and other characteristics that are responsible for the comfort of using a power tool.

A conventional electric household screwdriver with a power of up to 300 W is capable, for example, of screwing a self-tapping screw into a thin metal surface. More responsible work requires a power tool with a power already above 650 watts. Such devices will be classified as professional, the power of which reaches 850 watts.

The torque of a household tool is usually 25-30 N * m. This allows a 70 mm self-tapping screw to be screwed into the wooden base. If there is a need to work with more powerful fasteners, it is advisable to use devices with a torque of at least 40 N * m.

The rotation speed of the screwdriver chuck for most models is 0-800 rpm, which is quite enough when working with fasteners. This characteristic is adjustable, but in different devices, the speed change can be carried out by changing the pressing force of the button or by setting the desired value with the wheel of the regulator or toggle switch. In the course of performing a large amount of the same type of work, the second option for regulating the rotation speed is preferable.

Types of network screwdrivers

Devices differ in the type of cartridge – the mechanism for holding the nozzle (bits):

  • Devices with a gear (key) cartridge in which the nozzle is attached using a special key. This process requires some time and effort, but this mounting option is highly reliable.
  • A screwdriver with a keyless chuck is a very convenient mechanism in terms of ease and speed of changing the nozzle, but it is not reliable enough when working with hard materials. Distinguish one – and two-sleeve cartridges with one or two rotating rings.
  • The bit chuck is an accessory exclusively for screwdrivers, while the types of chucks already described are also used in drills, drill drivers, etc.

Also, the devices differ in the diameter of the cartridge, which determines how powerful the nozzle can be used in work. Non-professional power tools are usually equipped with a chuck with a range of 0-20 mm.

You also need to know how to choose a power screwdriver with a drill function implemented in the device. These power tools are called drills. Unlike simple models, they usually have two speed adjustment ranges:

  • from 0 to 400 rpm – work with a fastener;
  • from 400 to 1300 rpm – when drilling.

The power tool in question may also be structurally different in the type of motor – with or without brushes. The latter are more expensive, although they operate more smoothly, with low noise and do not require special maintenance (the brushes need to be changed quite often, so some manufacturers even complete their power tools with an additional set).

The best screwdriver for solving most tasks is a combined one, which has absorbed the advantages of not only networked, but also battery devices. It works both from the mains, having sufficient power even when drilling hard materials, and from its own battery, without needing access to a power outlet.

Choose the right screwdriver

The main thing you need to pay attention to when choosing this power tool is the power and the torque associated with it. For home and work, for example, with furniture, when you need to tighten relatively small screws or assemble some element, a screwdriver with a torque of 10 to 30 N * m will be enough.

Drilling wood can already be carried out with a drill-driver with more capabilities and a moment corresponding to 30-40 N * m. If one of the purposes of the tool is drilling brick, concrete or metal surfaces, then the torque of the screwdriver should exceed 40 N * m.

Which screwdriver to purchase must be decided in accordance with one more characteristic. Manufacturers usually indicate in the equipment specification the maximum diameter of fasteners that a given screwdriver can work with. In most devices, this is 5 mm, although there are models that can twist 10 and even 12 mm fasteners. In devices with a drill function, an important parameter is the largest drilling diameter. It can also be up to 13 mm in selected models.

Try to buy a tool with which you can work comfortably and safely. Many devices have auxiliary functions:

  • blocking the power button;
  • illumination of the working area with an LED flashlight;
  • reverse mode when unscrewing fasteners.

Also, the convenience of work is affected, for example, by the presence of an additional handle in the center, the rubber coating of the handle, which prevents the tool from slipping.

How to choose a screwdriver (video)

From the presented video you can find out how the network screwdrivers differ from each other using the example of four selected models:

Which screwdriver is better to choose depends on the tasks solved with this tool. Simple fastener assembly work can be carried out using an inexpensive low-power corded screwdriver with a quick-release chuck. If, in addition to standard tasks, you periodically need to drill holes in metal, wood, and even concrete, you can choose a drill driver with sufficient power and with a reliable key chuck.
