24 吋 背膠氧化鋯砂盤

Bought these for grinding welds on a trailer project and the zirconia grit just keeps cutting without loading up. The heavy Y cloth backing hasn't torn once even when I catch an edge, which my old discs always did.

Took these to the garage for some heavy grinding on steel and the zirconia grit held up way longer than the cheap discs I used to buy. The 24 inch size covers a lot of surface area, and the sticky backing hasn’t peeled once, even on a warm day.

The PSA backing sticks tight to my 24 inch grinder plate and doesn't peel up at the edges like the cheaper discs I've used. Takes a lot of material off fast on flat steel, though it loads up quicker than I'd like on painted surfaces. Still a solid value for the price.
