I did. I got a harbor freight one on sale and it cost so little. I also got the torque sticks that Matt mentioned. Well, turns out my son has never used the impact wrench anyway! He got a long handled torque wrench and is using that. The reason I wanted a power tool is that he often has to change his tires on the eve of it snowing here so it may be in the dark/cold and such and I wanted to make the process faster for him.
I recently bought a 20 volt Dewalt Impact wrench. Can these be used for heavy duty work like lug nuts? The chuck seems pretty small on it. It is a brushless unit by the way so it has a bit more power/efficiency.
Be sure to use a breaker bar to remove the nut & not the torque wrench...
