蠟戒管擴孔器，8公釐至15公釐 — 小型實心鋼孔徑尺寸工具，用於雕刻

The tapered flutes cut clean wax curls without grabbing or chattering, which makes sizing the bore feel more controlled. I like that it works from 8mm up to 15mm so you can fine-tune the inner diameter gradually. Definitely speeds up my rough-out stage.

The tapered flutes cut through the wax cleanly without grabbing, which makes sizing the bore much more controlled. I just wish it came with a small handle or cap for better grip during use.

I’ve been using this reamer to prep wax ring tubes for casting, and the tapered shaft really does open the bore cleanly without snagging. The solid steel feels sturdy enough for repeated use, though I do wish it came with a slightly more detailed guide for beginners.
