100 discs — sia's standard published pack for this article number.
What does open-coat mean at this grit?
sia electrostatically applies the abrasive grain in an open pattern from 220 grit up in this series, which helps resist loading on softer finishes.

No. It is a no-hole (NH) disc, built for sanders without through-pad dust extraction.
What grain does the 220 grit disc use?
Aluminum oxide, within sia's 100–400 aluminum-oxide grit band.
