What other brands of jaws will fit the chuck?

I'm not sure what other brands will fit the Deefine chuck, but the mounting holes are 18MM center-to-center. I purchased a set of flat plate lathe turning jaws a few years ago and their mounting holes are 20MM center-to-center. I've looked at a number of chucks & flat plate jaws on Amazon & none specify the mounting dimension.

what brand of lathe does this fit?

Hello our chuck is suitable for wooden lathes with 1 "x8tip thread or 3/4" x16tpi thread, suitable for all brand lathes. Thank you!

Where can I get the step jaws to add to the set?

It comes with two sets of jaws. For additional, I’d contact DEEFINE or web search.

can this chuck be used without round Jaws or big round jaws in metal lathe?
