12 吋 背膠氧化鋯砂盤，5 包

The adhesive backing on these discs holds tight even during aggressive metal grinding, and they've outlasted other brands I've tried by a good margin. They cut smoothly without loading up, which saves me time on big projects.

These cut right through the heavy grinding I’ve been doing on a steel project, and the Y-weight cloth backing holds up better than the paper discs I used before. The blue-green color is just a bonus, but the real win is how long each disc lasts without loading up.

The adhesive backing on these 12-inch discs holds tight to the plate even during heavy grinding, and the blue/green zirconia fabric lasts noticeably longer than the aluminum oxide ones I used before.
