Has anyone out there used, or can recommend a quick change adapter for the Chinese 2.2kw ER20 spindles? I have ran searches and seen videos, but I still haven't figured out if there's something appropriate or not. Something which requires no wrench would be great, tool holders with preset lengths, etc. Any ideas?

Dameronw,

Also, if anyone can enlighten me as to the differences between HSD, HSK, and all the other acronyms which have to do with spindles, that would be killer. I know that ATC obviously stands for Auto Tool Changer, but what are all the others?
