All these tasks require different torque levels, so it's important to take few minutes to write down what you plan to use the wrench for and find out the torque levels.
On the other hand, for heavy work such changing truck tires, or doing exhaust suspension work, wrench with more than 1000 ft lbs of torque is more suitable..
Well, bigger impact wrench means that the tool will be able to have bigger and more potent internal components that will output more torque as result..
Additionally, the form-factor allows for anvil, which increases the strength of the mechanism and increases torque. .
In, the larger the anvil size, the torque the wrench will produce because anvil means more surface area for the mechanism to develop.
So, if you need more torque, go for 4 impact wrench, whereas if you do not, 2 impact wrench might be the best choice..
Impact wrenches, in contrast to impact drivers, are known for providing higher levels of torque, allowing users to remove or fasten hundreds of nuts and bolts and even work on jobs that require higher levels of torque ..
The amount of torque needed to remove lug nuts is around 80 foot-pounds, and most impact wrenches with output of greater than 80 foot-pounds should be able to do the job..
then you may need wrench with output of at least 150 foot-pounds, as the torque will be necessary to break the rusted bond between the nut and bolt..
Is 400 Nm torque good for impact wrench. 400 Nm is about 300 foot-pounds of torque and it will be enough to cover the basics..
