What parameters should have a good household appliance screwdriver
this need when it is necessary either to screw or unscrew the screws, bolts, nuts or screws.Planted a drill hole and can be
main parameter is torque screwdrivers.It was on this indicator it is necessary to pay attention to studying the device passport.
What does the torque value
This parameter shows how the surface of the tool handle without problems.The lower torque so less dense should be a material that needs to be screwed in the screws.For household tools enough torque of 10 to 20 Nm.To protect the motor it is equipped with a special ratchet clutch.Thanks to her, with loads exceeding a threshold (maximum torque), the motor shaft starts to slip.
Qualitatively, the screwdriver is always a device that limits the maximum torque.It is done in the form of a ring and is located on the axis of the engine immediately after the chuck.Safety clutch and nozzle protects from wear, and will not allow the screws too deeply into the material.
limiter can be adjusted.Steps of adjustment is from 5 to 22 - more is better than less.
Select the type of food
screwdriver may be fixed, powered by a normal socket or battery.The latter option is more mobile, compact and convenient.But he has, and "pitfalls".If you do not use a long screwdriver, its batteries die quietly.Very often, this is what lies screwdriver and use it may come 1 time in 2 months.The batteries are discharged, they do not get a timely charge and gradually lose capacity.Therefore, it may be worthwhile to look at the not so convenient network device with a long cord - he will not fail.
Less - demand constant charging and rapid failure of the batteries.
Screwdrivers will be more weighty and clumsy than their rechargeable counterparts.But they can be stored indefinitely, and charge no need to worry.Long cord completely will make the necessary work, and if it is not enough - extension cable at your disposal.
downside network models is the high price.But with such a choice, as now, one can find quite a budget and the power screwdriver.
Choosing between these two types of power consider the conditions in which you will need to use the device and make a selection.
If the batteries, what
power unit is determined by the nominal voltage of the battery, and the duration of the work - in her capacity.Household screwdrivers have this figure at 1.2 - 1.5 amp-hours.Further, we note that most of these batteries are of three types.
- Batteries NiCad type commonly removed from production because they contain cadmium, very harmful to humans.It can cause allergies.But in stores appliances with a battery still sold.The battery that is resistant to frost and can be recharged up to a thousand times.The main drawback - it has a memory effect, which reduces the charge time from time.
- batteries are nickel metal hydride type are very light.The ability to recharge - five hundred times.
- batteries are lithium-ion type - high quality, has no memory effect, it is long.Unfortunately, fear of frost.

Professional devices are usually included an excellent device for charging, able to do its job in just an hour.Amateur models charge the battery in three or even five times longer.However, you decide - because professional models of chargers are much more expensive.In my opinion there is no need to overpay, so you can opt for a simple charger.
For quality screwdriving enough speed not exceeding 500 rev / min.Drilling is required 1300 rev / min, no less.The best option - the presence of the speed controller.
Choice brand manufacturer screwdriver
huge choice of models and companies capable of confusing inexperienced buyer.He had no idea what a screwdriver is better to buy for the house.They are so similar to each other, except that the colors and design are different - that's the first impression.
