5" 8孔 H&L 黑色 SC 微米砂輪片 40微米

The hook-and-loop backing holds firmly to my sander without slipping, and the 8-hole dust extraction pattern keeps my work area almost dust-free. I've worked through half the pack already with consistent results on my current finishing project.

I’ve been using these 40-mic discs for final sanding before paint, and the hook-and-loop backing holds firm with no slipping. They cut cleanly without clogging up too fast on bare wood.

Finally, a disc that actually stays on the backing pad without peeling off mid-sand. The hook and loop grip is firm, and the 40 micron grit cuts through old paint surprisingly fast.
