Overview 6 species best rechargeable screwdrivers: how to choose which one to buy, the pros and cons, features, rating

Wrenches, the energy source for which the batteries are designed for autonomous operation with fasteners of varying complexity. The tool is dependent on electricity, but it is independent of the network. This expresses the user experience rechargeable versionsBut there is a downside - the process continues until such time as the battery is exhausted.

How to Choose a Cordless impact wrench

Among the mass of the models offered by manufacturers found both wrenches with decent specifications, and frankly "disposable" products. Given that the tool is required to perform its functions effectively, while delivering reliability and resiliency, his choice should be approached, guided by the parameters listed below.

Rotational speed

The higher it is, the faster the job done. Shaft speed for domestic models of 400-500 rev / min, while the professional tools often exceeds the rate of 1500 rev / min.

range of application

This characteristic is responsible for the size of nozzles, which is capable of working wrench. If we are talking about household tools, It is optimal for the range of 10-12 nozzle dimensions M12-M24. To work effectively with big fasteners use a different type of tools, such as pneumatic.

Torque

Another important characteristic of the wrench. Torque - is the force with which the tool acts on the fasteners. The higher it is, the more complex the nuts and bolts particular model can handle. At the household index options, usually does not exceed 600 Nm.

The firing mechanism

Distinguish between stressed and unstressed tool. the first value is higher, but a wrench tightens attachment member is easier and also more reliable. Employment impact mechanism is as follows: while screwing the nut on the go without any effort, it shocks the long character and torque wrenches are increasing in strength. Unstressed options when working with the fastener is very heavy hand.

reverse

This function of the shaft rotation in the opposite direction. Not every model is equipped with a thrust reverser. If this option is not available, the tool is used either alone or for tightening fasteners to loosen, depending on the direction of rotation. It should be considered.

Housing and ergonomics

Housing the best models made of metal, which makes the tool extra strength and durability. Furthermore, metallic products better remove heat from the working elements. Often used as a special reinforced plastic. In terms of strength, it is slightly inferior to the metal, but with careful operation is relevant because of the low weight. Work hard tool leads to hand fatigue.

Before buying a wrench, you should evaluate how comfortable it is in your hand. You need to pay attention and on the location of the controls, how easy it is to work with them. Optimally, if the tool handle is located in the center, from which the weight is distributed evenly, and hence, the hand will get tired at work are much smaller.

Battery

Capacity battery - setting, which together with the motor power determines how long the tool. To produce wrenches removable nickel-cadmium or lithium-ion batteries, the amount of charge which reaches up to 1000 cycles. When choosing it is also important to pay attention to whether there is a second battery in the kit. It will ensure continuous operation of the wrench: while the first stands on the instrument, the other is charging. Some manufacturers equip a removable battery pack charge indicator light.
