أقراص جاتور سوداء من الزركونيا H&L صلبة مقاس 5 بوصات

I run these on a 5" random orbit sander for stripping old finish off oak and the zirconia grain just keeps cutting. The hook-and-loop backing holds tight and swaps out fast between grits. Easily the longest-lasting discs I've used on hardwoods.

These discs lasted way longer than the cheaper ones I was using before, even on rough oak edges. The hook-and-loop backing grips my orbital sander tight and doesn't slip mid-pass. I've gone through maybe a dozen and none have shredded on me yet.

The zirconia grain on these really holds up compared to the aluminum oxide discs I used before, still cutting fast after a full afternoon on my belt sander. Five inch size fits my backing pad perfectly with no wobble.
