قرص نورتون A273 صلب 8 بوصة بدون ثقوب من أداكس بحبيبات 400A

I've been using these on my aluminum boat project and the 8-inch size covers ground quickly without leaving deep scratches. The hook-and-loop backing holds securely even with my random orbital sander.

I was a bit skeptical about the 400 grit being fine enough for my boat's aluminum trim, but the no-fil design really kept it from loading up. These left a smooth, even finish with no swirls, exactly what I needed for a showroom look.

These 8-inch discs cut through my aluminum boat project leaving a smooth, even finish with the 400A grit exactly as described. The hook-and-loop side grips the backing pad securely, and they're holding up well on marine metal without loading up.
