أقراص صنفرة زركونيا ذات ظهر لاصق 9 بوصة، 5 قطع

I switched from regular sanding discs to these zirconia ones and noticed immediately how much longer they last on my metal bench grinder. The blue-green color makes it easy to track which grit I'm using.

The adhesive backing on these 9-inch discs grips the sander firmly with zero slip, even on heavy metal grinding. I’ve used them on hard steel for several projects and the zirconia grit holds up way longer than the cheap fiber discs I tried before.

These zirconia discs cut through steel much faster than the standard aluminum oxide ones I used to buy, and the adhesive backing holds firm even after heavy grinding. The 9-inch size is perfect for covering large surface areas quickly without leaving deep gouges.
