Expanding Ring Mandrel with Hex Allen Key – Set of 3 Premium Stainless Steel Ring Mandrels Lathe – Heavy Duty Ring Shaper Tool for Ring Turning and Ring Making – Ring Sizes(4-14) - by MaxoPro

Delivery was excellent. The mandrels is a very good quality and works very well.

The tools seem well made, round stock centers easily on the mandrel and tightens easily with the included wrench. Good finish, no burrs.

Mandrel works well. Firmly held ring core without causing any damage. Would have liked more if mandrek was stamped kr etched with sizing. No size indication at all.

The media could not be loaded. The machining is not that accurate as it says. It’s vibrates a lot.

Works as intended.

I needed a mandrel that would work for 7 1/2 and size 10- 12 . These are either too large or too small

I've purchased others that are more expensive but harder to use as an amateur. This is so simple & lightweight. No manual is needed.

It’s for mounting in a lathe or drill press for forming jewlery, esp channel set rings.

Very weak broke after a handful of uses

悪くはないが価格がちょっと高いかも
