Description

A stepped ring mandrel gives a band flat, straight ring-size steps to sit against, so the ring stays put instead of creeping while you form, true, or finish it. These steel mandrels come in two versions: one stepped in full sizes 4–16 and one stepped in half sizes 3.5–15.5, so you can pick the one that matches the way you size.

Features

  • Straight stepped design suited to wider rings, which will not seat properly on a taper
  • Each step is clearly delineated for accurate ring sizing
  • Offered in full sizes or half sizes to suit different sizing workflows
  • 13" (330 mm) overall length gives a secure grip while working
  • Individual stepped sections measure 7/8" (22–23 mm) in length
  • Steel construction

Accurate stepped ring mandrels

I tried an Amazon product and it wasn't accurate. I had to buy 2 for 1/2 and whole sizes but brilliant idea. Wish they had thought of these sooner! Thanks 😊
