After waiting a month to get this air grinder, when it arrived the air connector is not what is shown in the advertisement. The fitting does not work with any U.S. type air fitting. I drove over 140 miles going to different hardware and parts stores looking for any connector that I could get to adapt or connect to standard fittings used in the U.S. None of the stores had anything I could use to make these fittings work. I contacted the company and was told it is as advertised. Look at the pictures for yourself. I sent these same photos to the company. They finally sent an e-mail saying they would send the fitting. What they sent is the female connector for the fitting that came with the grinder, still useless in the U.S. If your looking for a high speed air grinder you’ll probably want to look somewhere else, otherwise you may find your self with a grinder that you can’t use.I see they have changed the photo. It now shows the fitting came with the one I bought. That was not the photo in the advertisement when I bought it. My 1st photo shows what was advertised. It is a screen clip taken from the original advertisement on Amazon.

The main air chuck won’t work with anything I have be able to find. Without being able to hook it up to an air chuck (USA SAE type) it is worthless. I have not found any adapterss anyware. I think this is a miss leading item sold by a company that does not care if it works, just as long as they get their money. Unless you can figure it out DO NOT BUY
