In order to determine exactly which network screwdriver is better, you need to know the main characteristics for which you should choose it and which one is responsible for what. Even the form of the case can tell where you can use a particular device and whether it is worth stopping at it your choice, and the remaining characteristics will give an exhaustive picture of its capabilities.
Not all characteristics can tell how a particular tool will perform its duties well. But there are some points that need to be paid attention to in order to determine which network screwdriver is better.
Directly shows how much the device is “voracious” in terms of power consumption and indirectly indicates its weight and size. Depending on the class of the tool, it can be equipped with an electric motor per 100-900 watts, but here “more” does not always mean “better” - it all depends on how the screwdriver will be used. If this is periodic work around the house, then a lot of power can hurt, because these devices are often “with character”, to which you have to get used. Optimal will be the choice of tools with a capacity of about 500 watts - this is quite enough for everyday tasks when using a network screwdriver.
Indicates how much a bit can affect a screw - it depends on what materials you can work with using a particular screwdriver. In household, most often it is 10-15 Nm, professional give out 30-35 Nm, and in screwdrivers with a pulsed mode, this figure reaches 100 Nm. However, in the latter case, this is not entirely true, because this figure is made up of the amounts of effort - the screwdriver does not “pull” the screw or nut in one motion, but acts on it with a series of small impulses - this can be compared with the fact that start tapping on it with a hammer. Such pulses can be from 2 to 4.5 thousand per minute.
When using the tool in everyday life just like a screwdriver, this is not the main indicator - in any case, it will be faster than manually unscrewing the screws with a screwdriver. If you plan to use the device as a drill, then the higher the revolutions, the more accurate the drilling and the smoother the hole.
Since the screwdriver is designed to tighten and unscrew the screws, this is a mandatory function in all devices without exception. Here, more attention needs to be paid to exactly how the switching of modes occurs - the convenience of operation and reliability of the device as a whole depend on it.
Most often, this is a button near the start button, which is retracted on one side and pops up on the other.
But models can come across with a separate lever that can be broken off quite easily. A warranty case, of course, such a breakdown is not.
Many manufacturers in their tips on how to choose a network screwdriver, include this function in the list of mandatory advantages of the device, but practice shows that tangible benefits from it is not as much as it is presented. If the screwdriver with the keyless chuck and the clutch closest to the body is small, then the spindle lock will help to unscrew the far clutch and release the chuck jaws to replace the bits.
But more often than not, this function is not used, because it is easier to hold the far coupling with your hand and press the start button - the screwdriver will unwind the cartridge. Still, if "Monsieur wants to know a lot about perversions," then you can lock the spindle and use a screwdriver like a regular screwdriver, but this clearly does not add karma.
Pay attention to this parameter if the screwdriver will be used periodically as a drill. In this case, there will be an additional mode switch on the case - in the mode of a screwdriver (up to 500 rpm) and a drill (about 1500-2000 rpm). This function will be especially useful when drilling metals - the higher the speed, the more accurate the work will be performed. There are devices with higher rates, but this is already a category of specialized tools designed for specific tasks.
Another function that migrated to the screwdrivers from the drills. It will be useful, if you often use the device to work with different materials, but at home it will most likely remain unclaimed - when tightening several screws it is much easier to set the desired speed with a hammer.
The start button lock is definitely needed by a professional screwdriver equipped with a tape shop - there is a clutch that unwinds the bat only after it “hooks” the screw.In the domestic version, the presence of blocking is justified only in one case - if the power of the screwdriver's engine allows it to be used as a drill. But it must be borne in mind that this is not his direct duty and something to drill "until the arm gets tired" or to use a screwdriver as a mixer for putties and other solutions, is fraught for his health.
When choosing a net screwdriver, it is quite possible for a model to make a rating of yourself based on the shape of the device. First of all, ease of use depends on it, and also the body of the screwdriver will partially tell about its internal filling and capabilities.
Most often this is a sign of a budget model, especially if the body is completely made of plastic. If you disassemble such a screwdriver, you will find that the motor shaft is directly attached to the chuck. That is, the quality of work directly depends on the engine power and its smoothness. Often, the owners of such devices complain about the rapid heating of the body during operation, but for occasional short homework such a screwdriver will fit perfectly. This form of the device allows you to push the screw during tightening, which will inevitably have to do due to the low engine power.
In general, this is the same device as in the shape of a gun, but the handle is shifted to the center of the case - it is considered that It is less annoying hand when working. Here we must take into account that all devices have different electric motors, each with its own mass, centering and other characteristics. It will be difficult to judge how convenient this or that model is without holding it in your hands.
This is already a sign of a class of professional devices, since the characteristic “puziko” indicates the transfer of force to the cartridge through the gearbox. This means that the bit rotates more smoothly, and it is easier to regulate the number of revolutions per minute. Even for the "tum", it is very convenient to support the screwdriver with the second hand (if there is no additional handle) - during prolonged work this will have to be done, because the weight of such devices is about 1.5-2 kg.
There are two main types of cartridges: quick-release and hex with a magnetic holder - each of them has its own advantages and disadvantages, Therefore, it is only possible to definitely recommend any of them knowing exactly where and how the screwdriver will be used.
Keyless chuck - the bits are clamped with cams, which are tightened with couplings on the threaded connection. This is the most common version of the cartridge, installed on budget and professional tools. Two couplings can be divided into the upper one, which is closer to the bit, and the lower one - near the screwdriver body.
To install a bat, you need to take hold of the lower clutch and start spinning the upper one - the cams will disperse, a bit is put between them and clamped. Since the lower clutch is usually tightly connected to the motor shaft (or gearbox), you can simply take up the upper clutch and press the start - the cams will disperse and shrink if you turn on the reverse.
Hexagonal cartridge with magnetic holder is structurally simpler than quick-clamping - it has no moving parts. It is made for quick replacement of bits: there is no need to twist anything - the bit is simply removed from the mount and another one is inserted in its place. In addition, it is easier to install a screwdriver depth limiter on such a cartridge, which comes standard in many professional screwdriver models. The only negative point is that the bit may slightly “play”, because nothing rigidly holds it in the cartridge.
For screwdrivers that can be used as a low-powered drill, drills with a hexagonal shank are available - they have a cutout for the locking ring so that the drill does not remain in the board after drilling a hole.
If a certain model of screwdriver is selected, but it has a cartridge that is not suitable for certain tasks, you can always buy adapters - they are low in cost and the quality of work will not be affected when using them .

These tools in their characteristics are close to professional models and masters often use them in places where greater mobility is not required. Often these are versatile devices, making them a good choice for home use.
