PSA مقاس 5 بوصات 8 ثقوب (3 ثقوب لولبية) لدوالت/بلاك أند ديكر

The 8-hole pattern lines up perfectly with my orbital sander and the dust collection actually works now. The PSA backing holds tight through a whole sanding session without peeling at the edges.

The 8-hole pattern lines up perfectly with the dust ports on my sander, so almost nothing gets left behind on the surface. Three screw holes keep it from slipping, which is a nice change from discs I've used before.

The PSA backing sticks way better than the peel-and-stick discs I used to buy, and the 3 screw holes lock it down so it doesn't fly off mid-sanding. Went through a whole batch refinishing cabinets and never had one slip.
