Screwdriver buying guide

Among the essential tools for DIY enthusiasts, mechanics and garages, we find the Wrench, more commonly called impact wrench or unbolter.

How does a wrench work?

This is a power tool specially designed for to screw and unscrew nuts, screws, and of course tighten and loosen bolts. For example, mechanics use it to remove your wheels when you need to change your tires or your brake pads.

The impact wrench consists of several parts: a Engine, a anvil, a impactor And one spring. She screws and unscrews by a striking mechanism. The effectiveness of this rotating machine lies in the succession of impacts sent in order to resist blockages. Note that the impact wrench has several interchangeable bushings very useful when you have several diameters of different bolts to assemble or disassemble.

Three types of screwdrivers: the comparison

The wired electric shock wrench

It is the most frequently sold model for its efficiency and relatively reasonable price. It looks a lot like a screwdriver and combines the mechanisms of hit and of rotation for the screwing and the unscrewing.

The only downside, you have to have an electrical outlet nearby and its power is not the strongest if you consider all types of unbolters.

The impact wrench with battery

The cordless impact wrench is sought after for its practicality. With her lithium-ion battery (li ion) that charges quickly, you can take it anywhere and access difficult places. However, beware of Weight tool because the battery makes the object heavier. Take the time to see if theergonomics and the grip be right for you. In terms of power, the cordless impact wrench is a little lower than the wired which will perform better.

The pneumatic impact wrench

This is the category of bolters the most expensive and also the most efficient. It is recommended for intense work, it is more powerful than the electric wrench. The pneumatic impact wrench is connected to a compressor which increases its efficiency but causes a little more noise than other impact wrenches.

The criteria for making the right choice

The fundamentals

The tightening torque : measured in Newton-meter, the torque indicates the tightening force of the impact wrench.

The number of impacts per minute : it characterizes the speed of action of your tool. The higher the number of impacts, the better your impact wrench will perform.

Theenergy supply : Regarding the corded electric impact wrench, the type of energy has no impact on the efficiency of the tool.

On the other hand, for the screwdriver lithium-ion battery, choose a intensity (V) And one amperage hour (Ah) bred for better Autonomy and better power.

Finally for the pneumatic impact wrench which works withpressurized air, take into account the pressure necessary for the device and air flow provided by the compressor.

The weight : if you have to do a lot of work over a long period of time, prefer a light model which will be much more manageable and more pleasant to use, especially for screwing / unscrewing at height. Feel free to experiment and weigh several models until you find the best one for you.

Secondary criteria

- the Rotation speed

- the handle coating

- theergonomics of the impact wrench

- the length of the cable for wired models

- the type of battery and its number

- the price

- a progressive trigger

- the breakaway torque(maximum release force)

- the battery life indicator light for battery models.

What you must remember

Now that you have an overview of all the criteria to take into account, know that the purchase of your impact wrench should be done according to the usefulness you will have of it.

First and foremost, you need to understand your needs.

If you need an impact wrench that will serve you occasionally (eg: to change your tires twice a year, to mount a fence or a garden shed), it is not necessary to invest in a tool. high end with lots of options and that will be expensive. Instead, opt for a high-performance, sufficiently powerful and practical model without any frills.

For larger, longer-lasting and more intensive work, choose an impact wrench that is easy to handle, light, powerful, with good user comfort and of course performance suited to the use you will have of it.

Provide in all cases impact sockets and not conventional sockets which risk breaking on first use. And don't forget, to have a device that is neither over-sized nor under-sized, choose the right one couple depending on the work you will need to perform and the Tightening.
