Many wide, delicate or unusual rings are difficult to hold with an outside clamp. This attachment adds inside ring-holding capability to any BenchMate. 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 this 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 won’t scratch or mark rings. With an extra collet set, you can “double-stack” collets for extremely wide rings or hold several rings simultaneously for high volume work. Includes holder body, 7 collets, expansion screw, and wrench.

  • Great for holding rings from the inside
  • Works with most GRS blocks and vises
  • 10 piece set
  • Great for stone setting and ring engraving
  • Includes holder body, 7 collets, expansion screw and wrench
