Description

Steel stepped ring mandrels offer a practical solution for jewelers working on wider bands and rings. Unlike tapered mandrels, the stepped design features straight, flat ring-size steps that keep rings from shifting during forming and finishing work. Two versions are available: one covering full sizes and one covering half sizes, making it easy to select the right fit for your sizing needs.

Features

  • Straight stepped design ideal for working on wider rings
  • Each step is clearly delineated for accurate ring sizing
  • Available in full sizes or half sizes to suit different workflows
  • Substantial 13" overall length provides a secure grip while working
  • Individual stepped sections measure 7/8" (22–23 mm) in length
