Engrave or set stones anywhere on the outside of rings with this inside ring holder from GRS. Designed for use with the GRS Benchmate Encore QC or QCX, this fixture includes 10 expanding nylon ring mandrels in diameters 13.5 to 22.5 mm, 1 set of standard expansion cones, 1 set of locking cones, and a drawbar. The standard cone set allows the ring to be rotated with adjustable friction while the locking set keeps the ring stationary. Made in USA.

Not compatible with the Original GRS Benchmate.
