I'm really puzzled here. My Remac mill uses an ISO 30 tapered chuck and it's retained by a draw bar.
However, all ISO 30 chucks that I can find, uses M12 draw bar thread, but both my chucks use 16G 3/8" Whitworth thread?
I'm sure I can easily make an M12 draw bar, but I would like to get to the bottom of this. Do I have the chuck type completely wrong, or what?
Below are two pictures of my chuck. The holding system is a Clarkson Autolock:
