أقراص نايلون زركونيا زرقاء نورتون 5 بوصة 5 ثقوب (لفة)

I've been using these on my random orbital sander for some heavy stock removal, and the five-hole pattern keeps the dust collection working perfectly. The PSA backing holds strong even when the disc gets hot from continuous use.

The PSA backing grips the disc firmly on my backup pad, and it peels off cleanly with no sticky residue left behind. The roll format is convenient for storage and easy to tear off a new disc when needed.

The five-hole layout keeps my shop vac from clogging even during heavy sanding sessions. They also stick to the backing pad securely without leaving residue behind.
