Just wondering when you would use the hexagonal instead of the square?

When in a 3 jaw chuck?

Milling nuts and bolt heads are the main use for me. OK mine are 5c bought way back when but principle is same.

When you want to put six sides on something rather than four?

Sorry.

Hi Chris,
I bought the hexagonal one to use for sharpening 6 flute milling cutters. As others have said you could use them as a quick way drilling 3 or 6 holes around something.

Use with a V-block and the six-sided block can be used to mill 12 facets. I bet even John S. hasn't worked that one out

Might be a good idea to point out to Chris that the idea behind these fixtures is for using them on a mill, not as cheap collet holder in a lathe chuck.

I didn't think of turning them!

I usually use an indexer.

Yes I would use it for holding round things on the milling machine.
