Aluminum Oxide Sanding Discs:

Abrasive Material: Yellow-brown Aluminum Oxide (Aluminum Oxide Grit) – High hardness and sharp edges.

Application Scope: Wood polishing, rust removal, metal oxidation layer removal, old paint stripping, and putty sanding.

They are not suitable for grinding or polishing hard stone or concrete surfaces, as the abrasive will wear off quickly and fail to cut effectively.
