What is the best cordless screwdriver: top producers

Man is constantly improving tools. Modern tool It is becoming more efficient, more compact, allowing faster and better to carry out tasks. Manufacturers are increasingly paying attention to the development Autonomous powerWhich allows you to work in tight spaces without a direct connection to the mains. In this article we will look at what is best cordless screwdriver - battery or mains, the advantages and disadvantages of the device, and what to look for when buying.

The cordless screwdriver is better in comparison with the network power tools

Wired and cordless screwdriver performs the same function - boring, Twisting and twisting various fasteners (Depending on the characteristics and nozzles). However, the battery power tool has several indisputable advantages over wired models, namely:

device screwdriver

Using a cordless screwdriver at home, it is useful to learn about its structure, which will help in the further exploitation. Of course, if there is no special knowledge, you do not you will make, if necessary, for example, an electric motor, but some damage still can be solved simply by replacing this or that detail.

Regardless of the model, any cordless screwdriver consists of the following elements:

• housing;
• DC motor;
• planetary reductor;
• speed control button;
• reverse button;
• keyless chuck;
• load limiter;
• accumulator battery.

The electric screwdriver to the main assembly. motor execution standard and includes winding the anchor and brushes. Voltage supplied to the motor through the graphite brushes. motor rotation direction depends on the polarity of which changes when you press the reverse button.

The second most important hub screwdriver is a planetary gear consisting of a ring and sun gears, carrier and satellites. They often fail in the operation of the power tool, especially if all the elements of the gear made of plastic, as in the low-cost models.

Speed ​​control is widely pulse controller and a key formed on the basis of the FET. Is controlled by a variable resistor, and the speed of rotation of the cartridge, respectively, depends on the power button is pressed.

Without battery (rechargeable battery), of course, screwdriver will not work, because it is responsible for supplying the DC voltage to the motor. Through the development of technologies for battery screwdriver become more capacious, and at the same time compact. The battery consists of several supply elements placed in one housing.

In can range 9-18 depending on the model and manufacturer of the voltage range B. Accordingly, the higher the voltage, the stronger the screwdriver.

How to choose a cordless screwdriver Home

As the number of manufacturers of power is constantly growing, and, respectively, and expanding their range, sometimes the consumer is in difficulty when selecting a suitable screwdriver. Therefore, to facilitate this task, consider the basic criteria that need to pay attention to when buying a tool.

The first step is to determine the order, for what purposes and how often to use screwdriver. When it is expected its application a few times a year and in the home, it is better to buy an inexpensive household screwdriver. In fact if the tool needed for work, you should give preference to a professional model.

Speed ​​mode

the rotation speed is very important when choosing the tool, because it determines its functionality. Typically cordless screwdrivers and screwdrivers have only one speed -. 0-800 rev / min, which is enough for screwing or unscrewing the fasteners. But in most models with screwdrivers drills feature has two modes:

1. Curler - 0-400 rev / min.
2. drilling - 400-1300 rev / min.

Torque screwdriver

Torque - a measure of the force with which the tool is running. It is measured in Newton-meters (N / m), and for domestic use enough index of 15-20 N / m, and for professional tools it should be up to 100 N / m.

cartridge

Before an electric screwdrivers and completed with conventional cartridges, in which the nozzle or the drill bits recorded by means of a special key. Now, almost all the models of this type of power tool equipped with a quick-lock mechanism that allows to replace the nozzle quickly. It's enough to close chuck arm and turn low speed in the right mode.

Additional options

In addition to the standard options, screwdriver can be provided and additional features that improve usability of the tool. Nice to complete with a screwdriver comes with a special case for convenience store and transportation (expensive models usually already packaged in a plastic case with a set of nozzles). An added convenience is the presence of the backlight, which makes it easier to work in poorly lit areas.

What is the best battery for screwdriver

Battery life for screwdriver depends largely on the duration of battery life and functionality. It is for this reason that when buying an instrument you need to pay attention to the type, voltage and battery capacity. Screwdriver used three types of batteries:

1. Nickel-cadmium (Ni-Cd);
2. Nickel-metal hydride (Ni-MH);
3. Lithium-ion (Li-I).

Nickel-cadmium battery

Batteries of this type are usually equipped with screwdrivers for household use. These low-cost, reliable battery, energy-intensive and at the correct use can withstand up to 1000 charge / discharge cycles. In addition, nickel-cadmium batteries have the longest shelf life (up to 5 years). However, Ni-Cd batteries exhibit a fairly unpleasant drawback consisting in that when incomplete charging or discharging the battery quickly loses its capacity and self-discharge (20% charge for the month just me). It must be considered, having decided to buy the battery with a screwdriver.

NiMH batteries

Nickel-metal hydride batteries have a small weight, a considerable capacity (at 30% more than that of the battery described above) and impact resistance. A disadvantage is the same as that of the nickel-cadmium battery, and a low level cycles Charge / discharge (units 400-500.), the charging duration - up to 3 hours and samorazryadnost high (of the order 30% per month). In addition, this type of battery can not tolerate low temperatures, making it impossible to use them in the street in the cold season.

Lithium-ion batteries for screwdrivers

Lithium-ion batteries have a high capacity screwdriver, not a long time for charging and lack of self-discharge. The batteries of this type are no drawbacks of the above types of batteries, but still they have their weaknesses. Lithium batteries Screwdriver not tolerate overcharge or full charge, as this may destroy or cause the battery to explode. This feature of the lithium ion battery increases the demands on the battery charger and, therefore, makes them considerably more expensive than nickel-cadmium and nickel-metal counterparts.

What else you need to know about batteries

There is another kind of battery - Li-zhelezofosfatny, which is already used as a food item, but not in the power tool. This is due to the high price. The peculiarity of this type of batteries is longer service life (up to 2000 charge / discharge cycles) and a large discharge current discharge - up to 30 A. Therefore, for domestic screwdriver will be advantageous to use nickel metal hydride battery, and for professional tools - a lithium ion battery.

To the battery for a long time served, should abide by the rules of storage, which differ depending on the type of battery. Nickel-cadmium batteries can store is completely discharged, whereas the nickel-metal hydride needed to fully charge. Lithium-ion batteries can be stored in a charged or uncharged form.

Another option is the battery, which you need to look for when choosing - Capacity, measured in ampere-hour (A / h). To household power can buy a battery capacity of 1.2-2.4 A / h.
