5" 8孔 H&L Supergrit 無品牌 Mirka 白色砂紙碟

I’ve been using these white discs for a few weeks now and the hook-and-loop backing holds securely even on curved surfaces. The 8-hole pattern keeps the dust collection consistent with my sander, which really cuts down on clogging.

Fine dust control is exactly why I grabbed the 8-hole version, and the hook-and-loop backing grabs the sander pad firmly with no slipping. These white discs cut cleanly and last longer than the cheaper brown ones I used before, even on the 320 grit.

Picked up the 220-grit in a 50-pack for my auto body work, and these discs cut evenly without loading up too fast. The 8-hole pattern keeps dust collection consistent, which makes a real difference on my DA sander.
