CoruEdge grain blend
A precision blend of zirconia and aluminum oxide engineered to fracture in a controlled way, exposing a fresh cutting edge so the disc keeps biting through the entire session.
STARKE FORGE Premium Sandpaper
High-output sanding disc · Yacht & marine manufacturing
When the job demands maximum cut and consistent results across long sessions, Forge delivers. Built around STARKE’s proprietary CoruEdge Technology for professionals who can’t afford downtime, inconsistency, or a disc that dies halfway through a panel.
Why this disc
A precision blend of zirconia and aluminum oxide engineered to fracture in a controlled way, exposing a fresh cutting edge so the disc keeps biting through the entire session.
Resists the clogging that kills lesser abrasives on gelcoat, filler, and primer — stay in the cut longer and change discs less often.
Keeps the disc flat and stable under pressure for consistent contact. No chatter. No uneven cut. Repeatable performance on flat panels or compound curves.
Heat-resistant resin-over-resin bonding locks grain under the heat and pressure of aggressive dry sanding. No water or lubricant required.
Grit sequence
