How I wish I owned a lathe lolMy best advice would be to forget about this adapter. If you need a 5.6 mm or 9 mm module, you would be better off using the correct size module. I personally use only copper ones from DTR, but there are many options in nickel plated brass too.
YES, I sent them an RFQ. Hopefully they reply with something in the <$10/piece range.Not sure if this is what you want?
