CoruEdge — always razor-sharp
Semi-brittle corundum grains fracture in a controlled way during sanding, continuously revealing fresh edges. The cut stays aggressive from the first pass to the last.

Why this disc
Key benefits
Marine-grade mesh
Open-weave mesh channels dust and debris away from the abrasive, resisting the clogging that kills disc performance on boats, yachts, fiberglass, and marine substrates.
Built for dry sanding
The mesh construction is purpose-built for dry sanding. Maximum dust extraction means a cleaner workspace and a surface ready for the next stage.
Professional hook & loop
Durable hook and loop backing mounts fast and holds firm to any standard backing pad through sustained yacht-refinish pressure.
