30 بوصة قرص صنفرة زركونيا بظهر لاصق

These discs are chewing through the stainless steel I'm grinding with way less loading than the cheap cloth ones I used before. The Y-weight backing feels tough and the zirconia grain is clearly holding an edge much longer. This is my new go-to for serious metalwork.

The sticky backing held firm even when I was grinding down thick steel for over an hour. These blue discs cut fast and left a surprisingly smooth finish compared to the cheap ones I'd tried before.

I've been using these on my angle grinder for heavy metal fabrication, and the adhesive backing holds tight even on vertical surfaces. The 30-inch length gives me plenty of continuous sanding before needing to swap, which saves time on big jobs.
