I have a R-8 holder that uses the OZ-25 collets and wanted a MT-3 holder to utilize them as well. I was skeptical at first about this holder because of the low price but highly impressed when it arrived. I would definitely recommend it.

Works great!
Works great! Used this in place of a lower loose ball type for a vintage road bike headset. Perfect fit.
