Can anyone tell me what these items are called and what they would be used for?

I picked up a small milling machine tonight and these collet holders came with it. I'm wondering what the point of them might be? Do they have a name I could research?

Thanks
Bob

They are 5C collet blocks. very simple way to grip round stock to cut squares, flats, or hex using the milling machine vise.

I have used them before. Very good if you need to drill holes or mill flats on a round shaft. They are faster than a dividing head. They usually are stored in a wooden box.

From your photo they are quick release too. Clean the rust off gently and rub a little oil on them they should last you a lifetime. Nice Score

Yup,them is good yarbs for making quick square or hex shapes.

If you had some round shaped ones,you could grip round stock in them and make round parts---but wait!!----forget it!!!
