GRS® Indexed Layout Ring Mandrel

Ideal for laying out stones, scrollwork or other decorative elements, this GRS® tapered steel ring mandrel helps you accurately split rings into quadrants. The mandrel circumference is measured into 10° intervals with markings at 0°, 90° (on both sides) and 180° positions around the base for precise spacing. This mandrel accommodates ring sizes (US) 1-1/2 to 12-1/2 US. A smooth, highly polished surface helps prevent marring of the inner surface of the ring as you work.
