Iam told the name of the manufacturer is kowloon . suposedly located in hong kong.
Google must have been out to lunch that day, then?
'Coz that's the funniest thing a nearly 30 year part-year resident of Quarry Bay, on "the island", now and then referred to as "Victoria", with a Hong Kong "permanent" ID card has heard in long years!
There are (at least) two genuinely decent "primary" makers of drill chucks in PRC. More than one brand goes on their product.
I don't know or care how many bad ones. I have no more interest in buying "bad" drill chucks than already
empty whisky bottles.
I only know that Rohm buys s**t from one, so I won't go near a
formerly-good Rohm any longer, no matter where it is made. Nor a Jacobs, present era, either. Same reason.
One of the good ones knocks-off Jacobs design and does it as well as can be.
The other knocks-off Llambrich, Spain. All I've seen of those are adverts, but they have a good reputation.
Easier to buy the original Llambrich if you want really GOOD chucks, and
without the RISK, as they have a US outlet. In Ohio. Wasn't good stuff, the Buckeyes might tar, feather and run their ass out of the state. They know their machinery out Ohio way.

Their "Hybrid" keyed/keyless is a right handy bit of kit for a balance of speed AND controllable grip when yah need it.
