When a big fastener (lug nut or bolt) has been tightened for months or even years, when it’s rusted and stuck, and cannot be removed with a regular socket wrench, which tool do you turn to?
We all know the answer to that. Don’t we? It’s the impact wrench.
An impact wrench is used for loosening and tightening lug nuts in trucks, car suspension components and tires, heavy machinery like tractors, ship building and airplane construction factories and so on. Anywhere where a very high torque tool is needed to loosen or tighten a fastener on a piece of machinery.
Now, back in the days, pneumatic or air powered wrenches where the go-to impact wrenches for projects like this. However, since the early 2000s, cordless or battery powered wrenches have been coming on pretty strong.
They’re not only portable, but can now produce as much torque in ft-lb as air powered wrenches. Without an air compressor, you can’t use a pneumatic impact wrench. Which means you have to buy an air compressor first if you have to buy an air power impact wrench.
That also means they’re limited to use in the workshop, because taking them out means you have to carry a bulky air compressor along with you.
On the other hand, a cordless battery powered impact wrench has none of these limitations. It’s very portable, and there’re many latest models that will produce as much torque as those air powered ones.
Apart from pneumatic and battery powered impact wrenches, there’re also hydraulic impact wrenches which make use of high-speed hydraulic motors.
Hydraulic wrenches like this produce very high torque and have high power to weight ratio. You’ll find these in large construction sites like shipyards, automobile factories, and large repair shops where a suitable hydraulic supply is on standby.
With so many types of impact wrenches and even more number of tool brands producing them, choosing one for your own projects can quickly become difficult and time consuming.
However, we’ve taken our time to review many of these impact wrenches and I’ve listed 5 of the best right here in this article.
Here’s my list.
