The need for screwdrivers arises when you need to tighten or unscrew screws, screws, screws. The tool works much faster than hand tools, while sparing the surface. But for manipulations in hard-to-reach areas, you need to choose a mini-screwdriver, which is smaller.
Peculiarities
A small tool will work with screws and self-tapping screws about 4 x 16. Slightly larger fasteners can also be used. Corresponding self-tapping screws and screws are mainly used in the assembly of furniture. The designs presented by different firms may differ significantly. It concerns both appearance and practical characteristics.
The weight of a small screwdriver varies from 0.3 to 0.7 kg . Therefore, the tool is great even for high school students. Since pressure is hardly needed when working with small fasteners, the handle is made medium-sized - and it easily fits even in a miniature palm. For greater convenience and safety, non-slip plastic pads are used. In shape, the device most often resembles a pistol, although T-shaped structures are also produced.
Selection recommendations
How powerful a screwdriver will be is indicated by its torque. Simply put, this is the force with which the working part of the tool turns the hardware. If the torque is more than 5 Newton-meters (the indicator of a strong human hand), then you will have to work more carefully. There is a great risk of accidentally damaging the material or the attached product. The number of revolutions varies from 180 to 600 turns per minute.
If the indicator is close to the maximum values, then the device allows you to confidently work with large fasteners, screw them into solid foundations. For driving small screws and screws into soft wood, an even simpler drill-driver is suitable, giving out no more than 400 turns. Accordingly, the first option is more suitable for those who like to tinker and fix everything, and the second is more suitable for ordinary people .who only need to periodically twist or disassemble something. As for the batteries used, everything is simple - the total operating time is determined by the capacity of the drive. With the help of household mini-screwdrivers, storing a charge from 1, 2 to 1, 5 ampere-hours, it is possible to tighten or unscrew 60 - 80 medium-sized screws. The exact figure is determined by the type of substrate material.
Lithium-ion batteries are good at home, where it is always warm. But if it is planned to carry out a small part of the work outdoors in winter, nickel-cadmium batteries are preferable. True, they have a memory effect, which requires more careful handling. Collet mounting is more reliable than using a magnet. But here a lot also depends on the habits of the craftsmen, on the types of work carried out.
Miniature screwdrivers are rarely sold "neat ". Almost always, the kit includes attachments and bits. It is necessary to carefully check what accessories are included in the kit, whether everything you need is there, whether you will have to overpay for obviously unnecessary items. Attention should be paid to the reputation of the manufacturer, to how high-quality service he can organize. When buying, connoisseurs advise to always “figure out in hand” whether it is convenient to use the device.
Undoubtedly, Bosch-branded products are good. This manufacturer supplies mini screwdrivers for household and professional grade. Makita brand products are no less high-quality products, in which the fruits of the latest developments are often introduced. The designs are constantly being improved.
It is useful to pay attention to the brands:
- Metabo;
- AEG;
- DeWalt;
- Ryobi.
The lineup
Hitachi DS10DFL with a mass of 1 kg, it has a powerful battery - for 1.5 ampere-hours. It charges very quickly, but the capacity of a single battery may not be enough for intensive work, especially since the torque is not at all happy. Consumers also complain about poorly designed backlighting.
Another Japanese miniature screwdriver - Makita DF330DWE - has a torque of 24 Newton meters. Importantly, this does not interfere with charging the battery in 30 minutes, but even the excellent design does not cancel complaints about the weakness of the cartridge and the appearance of backlash. Connoisseurs consider the Metabo PowerMaxx BS Basic to be the best option - despite the weight of 0.8 kg, the device develops a torque of 34 Newton meters. There are no special reasons for complaints about branded products, you should beware of fakes.
Rules and nuances of using a screwdriver
The first requirement that consumers so often ignore is thorough familiarity with the instructions. It is there that the most important instructions and recommendations are set out, the observance of which allows you to work comfortably, with the best results. A lot of attention should be paid to the rechargeable battery: depending on the specific type, it is discharged or charged before it is completely discharged. It is categorically impossible to wipe off any dirt and stains with a wet cloth, especially pouring water. Only the use of dry or slightly damp sponges is allowed.
Store the mini-screwdriver only in a dry place where it will definitely not fall or be crushed by other things . An idle start helps to check the serviceability of the device before starting work. The nozzle must be oriented in accordance with the axis of the fastener. It is recommended to set a slightly lower speed value than it seems necessary, otherwise there is a great risk of damage to the spline. You cannot use a screwdriver instead of a drill for a long time - it will overheat and be broken.
