Impact tools are great but they are just one more tool in the tool chest. Improper use of a impact gun is just as stupid using a screw driver as a scraper.
My 911 lug nuts will never have a impact wrench used on them. I love it for my El Camino. I still just snug the lugs up and finish with a torque wrench.
One of my neighbors had been struggling with the nut that holds the blade on the crankshaft of his lawn mower. He had tried every combination of wedging the blade and wrench to get it off. He finally wheeled the mower to my house. He handed me some cheap socket and I told him it was not an impact socket. He said to use it anyway. It split into pieces in a second. I got out the proper socket and took the blade off in an instant. He was happy it was off but pissed he had spent 1/2 a day messing with it. I used a torque wrench to tighten the nut.
The proper tool used correctly makes life a lot easier.
