My little mill has an R-8 spindle nose, probably mostly because that is what I was used to working with on the Bridgeport where I was last enslaved. I do have an ER-25 set of collets that came with a R-8 mounting chuck to hold them, but rarely find use for them on the mill, while I do use them extensively on my Atlas 618 in a collet chuck I built from a Dean Williams tutorial.
