6 jaw chucks are used to hold round stock the same as a 3 jaw chuck would be used for. The advantage of a 6 jaw chuck is increased holding power while applying the same force to the work piece or the same holding power while imparting less force to the work piece. They are great for holding thin wall or delicate parts. They are way more expensive than an equivalent 3 jaw chuck. Nice find, I would definitely keep it. Regards, Jeff
What a nice chuck ,looks like new ! What make is it ? There is usually an initial or name on one side or the other. A lot of these were bezel chucks for holding delicate objects like watch crystal bezels.

and what may we ask did you pay for it ? Old guys like me like to know so we can groan and grump a bit ,it's our nature LOL
If you come up with a need to grab a wheel by it's outer edge, that is the chuck you will need. It's handier than using standard stepped chucks, because of the wider range of adjustment, but it will have the same centering problems as a three jaw scroll chuck does.
Sorry - I was looking at the photo cross-eyed or something. I was thinkng the steps were toward the INSIDE of the chuck, not the outside. Yes. That is a ring chuck. Great for making things like stepped collars. I wish I had had one of those when I made the stepped collar to set my camera on top of my microscope. As it was, I had to use pretty large stock, and make the walls a lot thicker to keep from squashing them while I gripped it from the outside.
I just looked again. That IS handy - it has steps both inside AND outside.
