5吋 8孔 PSA 紅色樹脂重型砂碟 100 E 粒度

Much stickier than the cheap paper discs I used to use, these grab the backing pad instantly and don't slip. The 100 grit cuts aggressively on my random orbital sander without loading up too fast.

First time using resin discs and the 100 grit cuts fast without loading up on my palm sander. The 8 hole pattern lines up perfectly with my dust collection, keeping the work area clean.

I’ve been using these PSA discs on my orbital sander for a few days now, and the resin bond holds up much longer than the paper ones I used before. The 100E grit gives a consistent scratch pattern on hardwood, and the 8-hole pattern keeps dust from clogging the surface.
