蠟戒尺寸擴孔器 — 大型實心鋼，19公釐至26公釐，用於雕刻戒指管

I've been using it to open up my thicker men's bands and the solid steel handle gives great leverage even on the hardest wax. The 19 mm to 26 mm range is perfect for my statement ring designs.

This thing ate through a 22 mm wax tube like it was butter, and the steel handle gives you real leverage without slipping. I’ve used it on three statement rings so far and the bore stays dead straight every time.

Finally, a reamer that actually handles the larger sizes without fighting it. The solid steel construction makes opening up a 22 mm bore smooth and consistent.
