This versatile GRS® inside ring holder set works with any GRS bench block or vise to securely hold rings during your engraving and stone setting tasks.
Each collet is fluted on the inside to ensure effective expansion inside the ring for a secure hold. Collets are made from durable, hard plastic.
Two set screws on the sides of the ring holder allows it to tilt forward and backward, making it easy for you to access the side of the ring for engraving or stone setting. These screws can be removed to create a lower profile for working under a microscope.
