5" 5 孔 H&L 黑色 SC 防水砂紙盤

The waterproof backing held up through a wet sanding session without any peeling, and the hook-and-loop grip stayed firm the whole time. Five holes meant less clogging than my old discs, so I got more work done per pad.

The five holes actually kept the dust from clogging the paper even on wet sanding, which surprised me. Hook-and-loop backing held firm the whole time, and these discs lasted way longer than the cheap ones I've grabbed before.

Switched to a finer grit for the final sanding pass on my last project and these discs cut cleanly without loading up, even on wet surfaces. The hook-and-loop backing held firm on my orbital sander through the whole session.
