This lets you hold rings from the inside like the BenchMate inside ring holder. It works with all GRS Blocks and most vises. Great for stone setting and ring engraving. For extra wide rings, get another collet set and double-stack the collets.
It allows greater access to the outside of the ring and keeps it from flexing while you work.
Channel, bead and bezel settings are surprisingly easy using the inside holder. From the set of collets, you select the closest size that fits inside the ring. The screw expands the collet to hold the ring securely.
These hard plastic collets will not scratch or mar rings. With an extra collet set, you can "double-stack" collets for extremely wide rings or hold several rings simultaneously for high volume work.
The horizontal holder includes the holder body, 7 collets, expansion screw and a wrench. For extra wide rings, get another collet set and double stack the collets.
