Air Impact Wrenches
Before the air impact wrench, changing a tire during a pit stop took at least a full minute. If you've seen a Nascar, F1, Indy Car or other pro race pit stop in the last 50 years, you know with the help of an impact gun those tires can come off and on in about 15 seconds. They can save you even more time in your shop, the first time you run up against a stuck nut that no amount of strength with a ratchet handle can budge. The rhythmic hammer nature of air impact guns can also break lose fasteners that make it difficult to hold the other side of, like axles and harmonic balance bolts.
