I don't know about them all being made in the same factory. I think it is more likely that castings come from one or more places, and all the smaller parts as well. They are also likely machined in various places, especially the smaller parts. Think cottage industry. They are then finished, painted, inspected, and labeled by the people who put their name or likely various names on them. I have found very nice Chinese stuff from the cheapest, no name "makers" as well as some quite poor stuff from the "brand name" stuff like Shars, Phase II, Fowler, etc. There seems to be inconsistent quality control and working to a price point to make a profit cutting into the chances of reliably and consistently turning out quality products. One buyer might get a near perfect set of collets, beautiful, while the next buyer of the same set might find gross errors and unfinished tools. Certainly the Chinese are capable of producing quality stuff, and have some factories with the latest and best quality machines and equipment, sourced world wide. The main problem seems to be greed by all concerned and trying to meet unreasonable price points demanded by their customers. I would love to tell you to buy so-and-so brand and you will be happy, but in my limited experience that is simply not true. My answer has been to get the cheapest I can find from a reputable SELLER, and then hold them accountable by sending back anything that does not meet my standards. I do not have a problem with making adjustments, and other easy fixes to the tools, because those shortcuts are much of why the tools are cheap. If it is machined poorly or inaccurately, then it goes back. If enough of us did that, the extra hassle the seller had to deal with would force them to demand better quality, and yes, that would cost more. The only real savings on third world tools is in their ability to get very cheap labor. They still need to build and inspect their products so they are consistently decently made. And the landscape is changing, little by little, and mostly for the better. For the time being I consider all Chinese tools as "projects or returns."
