Advantages of pneumatic wrench and conventional wrenches

Answer 1

The main disadvantage to this kind of impact wrench is simply how much power you have to control in order to use it. There are no variable-speed triggers, for one thing and power is difficult to adjust. So if you only need a little bit of power—say to remove a tiny screw—this device will be too much.     The main advantage involved here is simply that common air is so much cheaper. So you’ll find it less expensive to operate your wrench. If you’re operating a garage or auto body shop that uses a number of different wrenches, this can be a real advantage.
