It was their facemills and parting system that caused me to make that comment, the boring bars and turning holders do look a bit different. They are identical in shape and finish, which is - quite odd shot peened that initially made me think the chinese ones were aluminium.I think, in common with a couple of your other recent posts, that your logic is completely inverted in this case.
Just how many ways are there of making a (for example) SCLCR 1616 H06 toolholder? The premium-priced ones (e.g. see ArcEuroTrade Sumitomo) might look smoother, shinier and have nice laser-engraved markings, but how much of that is germane to the tool's function? As long as the insert pocket is robust and the securing screw is of a good quality, the rest is just new-age-maker-marketing-BS that only increases the price you pay.
