How to Buy the Best Cordless Impact Wrench
Torque can be defined as the force required to turn an object around its axis and with that, the higher the torque value, the stronger the impact wrench.
Even if the unit has a fast speed (measured in RPM), ultimately torque is king and it is the one that shows how strong the wrench is.
To remove lug nuts, you need about 100 ft-lbs. of torque but with old, rusted nuts, the required torque is much higher. Basically, the higher the torque value the better because this makes the unit very versatile in terms of its application areas.
There are 2 main types of motors that are used in cordless impact wrenches. Brushed motors have a simple design, but they are not as durable and not as efficient as their brushless counterparts.
On the other hand, brushless motors are the better option because they have a longer lifespan (due to reduced wear and tear), run at a cooler temperature and are more energy efficient.
Even though such motors are costlier than the brushed type, they are highly recommended and contribute greatly towards making the best cordless impact wrenches.
It is very important to consider the wrench’s weight because of fatigue. The heavier the unit, the faster your hand will get tired from holding it in position.
Generally, lighter cordless impact wrenches are recommended because of their easy handling but this might mean that some features are sacrificed so as to achieve this light build.
What you can do is to narrow your list down to the units that meet the specifications you need, then pick the lightest one from them.
A majority of these cordless wrenches run on replaceable lithium-ion batteries but most require you to buy the power station and its charger separately.
If a battery is included, well and good. However, if you are to buy it separately, ensure you get the right voltage for the machine, which is usually either 18 or 20 volts, as per the wrench’s rating.
For the capacity though, the larger the better. Measured in Ah (ampere-hours), this shows the charge capacity that the battery can hold and with a large capacity, you can power the wrench for a longer time with minimal battery-replacement or charging-interval interruptions.
5. Drive Size
The wrench’s drive is quite important as it aids in its torque performance. The higher the drive size, the higher the torque performance and this means that 1/2-inch drive sizes are better for heavy-duty work such as in removing tight and rusty wheel nuts.
On the other hand, the smaller 3/8 and 1/4-inch drive sizes are better suited for light duty work such as in removing fasteners in wood, concrete or metal.
6. Design Features
Lastly, you should consider the convenient design features that make the cordless impact wrench easier to use.
For instance, a soft grip makes the unit easier and more comfortable to handle, and also helps to absorb any vibrations that may cause fatigue.
LED lighting is also very convenient to have as it illuminates your work area, especially if you are working in the dark. With a time-delay, this lighting is even much better.
An LED battery gauge is also ideal as it helps you monitor the battery level at a glance while safety features for tool and battery protection help to enhance the wrench’s durability. Generally, you should ensure that the wrench you buy has as many of these features as possible.
With the convenience offered by a cordless impact wrench, it is important to consider all the necessary features that make up the most suitable piece for your intended use.
As you can see above, these features are quite varied per product but having gone through the cordless impact wrench review, you should be able to easily pick the best cordless impact wrench that suits your needs.
