أقراص 3M جولد 216U مقاس 5 بوصة 5 ثقوب PSA

I’ve been running these discs on my orbital sander for a week now, and the 5-hole dust extraction really keeps things clean. The pressure-sensitive adhesive backing holds firm even on vertical surfaces, which is a nice change from cheaper options.

The adhesive backing on these discs is genuinely strong—once they're on the pad, they stay put through heavy use. I've been getting a smooth, consistent finish without any tearing or lifting around the holes.

I was tired of discs slipping mid-sand, but these 5-hole 216U discs stay put from start to finish. The gold coating held up through a full door refinishing without loading up.
