أقراص نورتون H228 حمراء AO راتنجية صلبة عادية

Swapped out my old fiber discs for these 5-inch resin plainbacks and the difference is noticeable right away. The 100E grit leaves a consistent finish on steel, and the red AO material seems to hold up longer than I expected.

These 5-inch discs cut through welds smoothly without loading up, even after heavy use. The 100 grit is just right for taking off material fast while leaving a decent finish. Being a pack of 50, it should last through several projects.

I use these 5-inch discs for blending welds on mild steel, and the 100E grit holds up far longer than the cheap generic ones I tried before. The resin bond doesn’t load up fast, even on softer metal.
