I sold air tools to industrial companies for many years. All of your big industrial hand tools are air. Grinders, rammers, riveting, floor bosses, all of the heavy maintenance tools 1" and up impact wrenches. ect. These tools don't overheat or quit in dirty environments. Electrocution is eliminated. They are repairable. Energy, oil, foundry, heavy equipment, construction, they are very common. Google 'Atlas Copco' they are a major brand. The stuff you know is what we call "throw away" tools and they have their place but not in industry.
