The KBC stub length drills I bought were quite good. Made in Europe. Mine happened to be black oxide. The supplied case was not great I ended up getting a Huot when it came on sale. I'm pretty sure the drills are 135-deg point if that's an issue for you. I would have preferred to match my 120-deg center spot drills but you don't see that as often & 135-deg center drills are even harder to find. I bought a regular set of HSS KBC 118-deg drills a while back on sale with the expressed purpose to dub them for use on brass/bronze etc. They seemed pretty decent too. Not as good as Precision Twist or USA brands, but quite a bit less cost.
Don't have any adjustable reamers. What I do on question mark stuff is just call KBC, they have a way of looking up country of origin. If they are Chinese, well, then at least you know that going into it the deal. Might be ok or maybe not. Travers & other vendors do the same thing with their house brand, it can mean darn near anything depending on the tool.
Anything TMX/Poland is usually very decent quality IMO. I'm seeing some new euro countries on labels now, Serbia for example. Not much actual purchasing history though.
