About this product
Tapered Silicone Ring Mandrel
A tapered silicone mandrel for holding a ring from the inside while you sand or polish the outside.
The BRS Tapered Silicone Ring Mandrel grips the inside of the band with a ribbed, flexible taper. It gives you a centered, slip-resistant hold without putting hard jaws against the finished interior.The taper covers U.S. ring sizes 4 through 15 and mounts on a 6mm steel shaft for a handheld drill or a lathe equipped with a Jacobs-style chuck.

Setup and use

This mandrel is intended for finishing work, not cutting or aggressive shaping. The flexible silicone introduces some runout and is not a precision cutting fixture.
