4 x 48 吋 氧化鋁金屬砂帶，3 件組

Used these on a steel railing project and the 4x48 size fit my belt sander perfectly, the aluminum oxide cut through the metal much faster than my generic belts. Very impressed with how they handled the heat without breaking down during heavy use.

The closed coat really holds up—I ran these on a mix of mild steel and aluminum and they didn’t load up or glaze over like cheaper belts I’ve tried. Heat buildup stayed low too, which made the finishing pass a lot smoother.

Used them on a quick steel grinding job and the closed coat really does keep the heat down—no glazing or burn marks after several passes. Three belts in the pack means I’m not stopping to swap out mid-project, which is exactly what I needed.
