GRS® Inside-Ring Holder Set for Vises

This GRS® inside ring holder set works with your GRS vise or bench block to securely hold rings during your engraving and stone setting tasks. An expansion cone ensures equal pressure around the entire circumference of the ring, reducing vibration and marring. Use a single collet for rings with thin bands. Stack collets with the long expansion screw (included) to hold wide bands or several rings at once. Set includes a ring holder frame, seven hard plastic collets, an expansion cone, two screws, and an Allen wrench.
