Expanding Ring Mandrel with Hex Allen Key – Medium Size Steel Ring Mandrel for Lathe – Heavy Duty Ring Shaper Tool for Ring Turning and Ring Making - Ring Sizes(7.5-10.5) -

Very weak broke after a handful of uses

AWESOME tool that comes in handy. Great quality. I bought this when I was making my brother’s wedding ring (titanium) and needed a way to safely hold it in my lathe for grooving and polishing. This thing works GREAT!! It does work with a live center as well, however I recommend using a bull-nose if you have one, but it will work with a fully tapered/pointed center as well (i tried both just to see). 9.5/10.

These work, but are a little limited. I imagine if you have a bigger lathe than I do these would be more useful. Rings hold onto them alright, but for the price it’s steep.

Very satisfied with these mandrel, perfect for quickly polishing a ring and/or holding in place as you work

Value for money: This is exactly what I was looking for. Fits perfectly on on small lathe.
