Fine finishing — 120 is a leveling grit and never the last one; follow with 150 and/or 180.
Between-coat and Level-5 polishing — that's 240 (09928/09922).
Rated wood/metal/fiberglass duty — that range belongs to the aluminum-oxide discs (09871), not the net line.
And, given the gate: it is not for the buyer who needs a Hyde-published performance spec on the exact SKU — that buyer wants the sourced 09919, whose claims are stated against the model.
The research engine found no hydetools.com page and no 2024-catalog row for the 09923; its identity comes from the Hyde Store listing and GTIN. The net properties are inherited from the sourced 09919 family and flagged as such.
Is it the same disc as the 09919?
By all evidence yes — the same 9" net 120 disc, in a 25-pack instead of a 10-pack. The difference that's certain is the count; the difference to verify is lifecycle.
Who should buy the 25-pack?
A crew standardized on dust-free sanding that burns first-knockdown discs fast. A single serious job or a season of small ones is better served by the sourced 10-pack (09919).
Can I trust the no-clog and washable claims?
They are Hyde's for the net-120 family and almost certainly apply — but they are inherited, not published against this SKU. Keep that distinction in customer-facing copy.
Is 120 fine enough to paint over?
No — it's a leveling grit; follow with 150 and/or 180.
