قرص صنفرة زركونيا ذو ظهر لاصق مقاس 16 بوصة

Used these on my angle grinder to strip heavy weld splatter off steel plate, and the zirconia grain chewed through it without glazing over. The heavy Y weight cloth backing held up to the pressure without tearing. Got through a full day of fabrication work on a single disc.

Sticky backing grabbed the disc tight on my sander, no slipping even on steel edges. The cloth’s heavy enough that a single disc lasted through three projects before the grit wore flat.

I’ve been using these 16-inch zirconia discs on my angle grinder for a few days, and the adhesive backing holds firmly even under heavy pressure. The blue-green color makes it easy to spot wear, and they’re lasting longer than the cheap options I tried before.
