160MM 全線材形狀（三角形、圓形、鑲座、半圓形）

I was able to get crisp half-round grooves on a copper bracelet right out of the box. The CNC machining on these rollers really delivers clean shapes without any wobble, even on my first try.

Switching between the triangle and round rollers in the same mill is such a time-saver for my silver wire projects. The half-round shape created a perfectly uniform edge on my first try, and the CNC precision really shows in the consistent results.

The CNC machining on these rollers is spot on—every shape comes out crisp and even, no snagging on the metal. I’ve run silver and copper through them, and the triangle profile is exactly as sharp as I hoped, though it takes a bit of pressure to get a full pass.
