Video Description:
Our team walks you through how this double-cut carbide rotary file performs in real grinding and polishing scenarios. Watch a side-by-side demo on wood, aluminum, and steel to see why the cross-cut pattern clears chips faster on soft materials, while single-cut geometry suits hard metals. We also cover speed settings by material and burr diameter, proper tool clamping, and safety essentials—so you can choose the right burr and run it efficiently.
