Double Diamond 6 孔 H&L Porter Cable

The hook-and-loop backing grabs the pad firmly with no slipping mid-sand, and the 6-hole pattern lines up perfectly with the sander's dust ports. Just finished a whole cabinet door with one sheet and the grit held up way longer than I expected.

I was pleasantly surprised that these sheets stayed firmly attached to the sander without any shifting, even when I pushed hard on a curved edge. The six-hole dust extraction is a real plus—my workbench stayed noticeably cleaner.

The hook-and-loop backing grabs the sander instantly and holds tight through a full pass on trim, so no mid-stroke slip. Six holes keep the dust flowing, which made a visible difference in how long the sheet stayed sharp.
