The Ultimate Set includes all four highest-quality, stainless steel Expanding Ring Mandrels and a hex key. It serves the full range of common ring sizes and offers significant cost savings. These Expanding Ring Mandrels were custom-designed by Patrick Adair to meet a ring maker's special needs. The varied steps offer plenty of space to work on many styles and sizes of rings. The expanding aspect of the tool holds a ring blank securely, allowing for a high level of precision during all phases of ring making. These mandrels withstand sanding abrasion much longer than regular steel and will not rust. Each shaft is 1/2" in diameter and is designed to work in a lathe or a drill. The length was kept short (3") so the full tool remains true while spinning. 1. Small - Recommended for sizes 4.5, 5, 5.5, 6, 6.5, 7. 2.
