7 tips for choosing quality screwdriver

briefly about the varieties of tools

Today, there are a few basic types of screwdrivers, so choicesuitable price and quality need to exercise after you are familiar with the advantages and disadvantages of each of the embodiment.Thus, electric screwdrivers manufacturers produce these models that you can choose not only for the home and garden, but also for work:

• Network (electrical) or rechargeable.The first work on 220V, which is convenient if you need to work in the same place near a power outlet (for example, when the assembly of furniture).Screwdrivers, running from the power supply is not discharged, but as a drawback - the attachment to the outlet, which is not very convenient if you need to work in a place where there is no electricity.In addition, cord when wiring / installation work will always get in the way, that can also be attributed to the disadvantages of the choice of network screwdrivers.Cordless models are more popular and also can hold a charge longer than one hour of active use.They are increasingly used, both professionals and DIY enthusiasts.
  
• nourishing element is represented by a lithium-ion battery (Li-lon), nickel-metal hydride (Ni-MH) or nickel-cadmium (Ni-Cd).Lithium-Ion battery holds a charge for a long time, fast charge and also has no memory effect (we'll talk about it below).If you need to choose a quality screwdriver for construction and electrical works, give preference to the battery model with lithium-ion battery.The only, but significant drawback - the high cost of power tools, so to give a rare and repair work in the house, this option is better not to choose.Nickel-metal hydride battery is not an option less common execution.Because of its environmental performance on such an option already gradually moving all modern manufacturers screwdrivers.Of the benefits should be made smaller battery size (and therefore lower weight of the tool), and of the downsides - the high cost.And the last option that you can choose for the house and garden - nickel-cadmium battery.His undoubted advantage - is not expensive, so this embodiment is most often found in budget screwdriver.In addition to this positive development can be considered a 5-year shelf life (in other embodiments no more than 3 years).Pros do not give preference screwdriver with rechargeable battery, becausecharging time in this case is an order of magnitude longer than in the other embodiments, and in addition to nickel-cadmium battery to the charge storage is present.
• hex chuck or three-jaw.The first type of cartridge is suitable just for home and garden, if repairs are carried out very rarely and with the necessity of frequent replacement of equipment.If you want to choose a professional screwdriver, it is better to prefer a universal three-jaw chuck, also called quick-release.Its advantage - you can fix any bit or drill, the main thing that was the appropriate diameter.
• voltage 12;14.4 or 18 volts.The higher the voltage, the greater the power output for the electrician.If you need to choose a powerful screwdriver for screwing in long screws for metal, with a large diameter (for example, for roofing work on the roof of corrugated board), select the 18-volt model.For the assembly of furniture, household chores or cottages will be enough 12 volt screwdriver
• number of modes 1, 2 or 3. The simplest low-end models, single speed - they can speed from 0 to 800 rev / min.More reliable and popular - cordless screwdrivers 2 speed - from 0 to 400 rev / min (for tightening) and from 0 to 1300 rev / min (for drilling).The third speed can occur in professional variants.The number of revolutions per minute can be as high as 3000.

Recommendations for choosing

So that you know what to look for when choosing a suitable model for your application, offer to your attention some important tips from the experienced masters:

1. Consider torque tool (measured in newton, [Nm]).If you need to screw / unscrew the small screws in drywall and boards, is enough to choose a model with a torque of not more than 30 Nm.For professional construction and roofing works better to choose a model with a torque of over 40 Nm.
2. When drilling holes in concrete and brick is better to opt for a shock screwdriver.Most current models include this feature, but some of it may not be available, so it is once again, make sure it is available.
3. illumination over a start button can not hurt.Of course, some experts argue that the location of the torch over the battery more efficient, but somehow when choosing a screwdriver, pay attention to the fact that the lights in any case had.
4. get round models with memory.This function requires the battery runs out before you put it back into the charger.If you accidentally put on charging is not completely dead batteries, it will reduce its share in the amount of undischarged.Sometimes inadvertently memory effect can be the whole problem.
5. If you need a professional screwdriver for work, be sure to choose a more durable model with metal gears.In amateur and low-end models are plastic gears.
6. Pay attention to such parameter as the ampere-hours that display the battery capacity.Home is well-founded choice of the screwdriver 1.5-2 Ah.If you want to select the tool for construction, try to find a higher-capacity battery, but beware - it will cost more.
7. You need to know which company is better screwdriver.Among the leading manufacturers release Bosch (Bosch), Makita (Makita), Hitachi (Hitachi), Metabo (Metabo).It is better to overpay a little bit of money and choose a quality instrument.From Russian-made good quality of the firm and ZUBR Interskol.
