Should I go with air or cordless impact wrench?

Many have questioned whether a cordless impact wrench (see http://www.impactwrench.co) can be powerful enough to undo corroded nuts. They begin to doubt about the tool and prefer to use air compressor impact wrench. Well, here is the explanation!

Air impact wrench

An impact wrench that uses air to power up its motor usually has lighter weight. Why? Because it doesn’t have battery inside. There is no need to question the power because the compressor can deliver maximum energy to the tool.

The downside of this type of impact wrench is that the attached cord for power supply. What’s more, you also need air hose and other plug in to make this tool works. Another drawback is that you can only use it in your garage or car shop. Other than those 2 places, you better work on something else because you can’t bring it on the road to change your flat tire.

Air model impact wrenches usually come with cheap price tag. It doesn’t have portability feature that could put the price sky high.

Cordless impact wrench

Cordless impact wrenches, on the other hand, have been widely used due to its convenient. You will only need to charge the battery up and then take it anywhere you go. Just like any other impact wrenches, the cordless one needs a trigger to turn on the gun.

The drawback is that it could be heavier than the one attached to the cord. It usually looks bulky when held but it’s a great tool to be moved around because there is no cord or air hose to limit your move in the workspace. In addition, if the power decreases, it won’t have the full energy to tighten the bolts.

Since it is a portable tool, you can work anywhere during emergency at the parking lot or the roadside. Many reviews have claimed that there is no trouble in undoing bolts with a cordless tool because it powers up the same speed as the one with cord, when properly charged.

Manufacturers are competing to deliver the best and the lightest cordless impact wrench that will be less fatigue for the hands and more moves in a tight space.

Cordless impact wrenches come in relatively more expensive than those with air hose with similar features. The battery quality is the component factor that contributes to the price. Lithium ion batteries can retain power longer than any other type of battery to power up the torque.The portable impact wrench tool is the most expensive type in impact wrench lines.

The similarities between both impact wrenches are the volt models of 16-18 volts and the 4 drive sizes from 1 inch to 3/8 inch.

In a nutshell,

Your budget and the specs you need highly determine the tool you get. If you are a mobile person, then opting for battery operated impact wrench is a good idea. But if you are working near the power source most of the time, then taking the electricity or air compressor wrench tool is necessary for repetitive use.
